Supercycle

2026-08-21 | 17 views

The Supercycle is a two-person, four-wheeled pedal-electric vehicle. It’s designed as a practical alternative to the car for the average 13 km commute in France, but it’s also a fantastic vehicle for longer trips and adventures. The first models are based on the Velove Armadillo frame, designed by Flevobike, and retrofitted with Grin motors in either two- or four-wheel-drive configurations. A pedal generator replaces the traditional chain drivetrain, making for a comfortable, light, powerful, and low-maintenance ride. The suspension is amazing, regenerative braking takes much of the work off the mechanical brakes, and there’s no chain to look after. In 2026, we added a solar roof for the Sun Trip in Morocco. It powered the Supercycle through a 3,800 km journey using sunshine alone!

Mineral Surveying Deep Desert Bike

2026-08-20 | 13 views

I needed a robust off-road bike that could take on the Yuma Desert in the Gila Mountains areas. Using GPS waypoints, productive surveying and sampling of minerals can be done but the terrain and dangers are formidable. Fourteen varieties of rattlesnakes to start with and a 100+ degree desert that gets 2-3 inches of rain per year. Equipment failure out there is not an option so GrinTech equipment required for these extremes.

Semi-Recumbent Exercise Moped

I never liked to use stationary bikes at the gym, going nowhere on a bike doesn't seem natural. When I found this used Giant Revive DX online, I knew this was the exercise bike I had always been looking for. Giant agrees as their sales literature highlighted the computer ergonomic design it was based on. But it took awhile to get it right and it was good stuff from GrinTech that made that happen.

Brompton P-Line Rear All Axle Motor Build

2026-08-20 | 13 views

This build came about because I really wanted a regular brompton with a grin all axle motor, and my dislike of a front mounted motor on the brompton. I previously had a crystalyte front mounted motor build, but I didn’t like it all too much because of how easy the bike tips when it’s folded (need to usually have a hand hovering around it), and the limited crank options that come about when using a bottom bracket based torque sensor. To fit the motor, I had to use an aftermarket titanium triangle (from hexati or ti-atom) instead of the stock triangle (overall I’ve had no issues with the triangle). Other than that the current iteration of this build is kinda jank (haven’t gotten around to 3D printing a custom housing for the controller so it’s just held to the bike with some voile straps for now) It’s worth mentioning that I started this build before brompton rolled out their e-motiq rear mounted electric bromptons, but because the torque sensor they use has a much lower resolution compared to the all axle and erider, theres a pretty noticeable delay for the assist to kick on and kick off when you stop pedalling. Overall I didn’t like that as much - also no regen ) Overall the all axle motor has been great on this build, and my only gripe with it is overall weight. But because it has a cassette based torque sensor, I can save a bunch of weight by using a lighter crankset and skip the bottom bracket torque sensor - resulting in an overall weight similar to just the weight of a front mounted crystalyte motor. The weight being closer to the bike’s centre of gravity in the folded position, also makes the bike ridiculously stable while folded. Also despite being on the rear, the regen and braking force with the all axle is far greater than the crystalyte brompton motor. Quirks: - Because of how large the diameter of the motor is, and how small the diameter of the rim is - I did have to use schwalbe click valves (it’s better anyway) instead of presta valves, and had to machine a custom 90 degree click valve pump adapter to fit into the small gap between the motor and the rim to inflate the tires. - Some titanium aftermarket triangles may use a slight dish offset. For my triangle I just had to tighten all the right side spokes and loosen all the left side spokes to account for that slight offset.

Yedoo E-Scooter Version 2.0 – 3rd Build Project

2026-08-19 | 17 views

This is my second iteration of the Yedoo 26/20 e-scooter platform. My fourth primary goals for this version were: -More power without compromising anything else -Significantly improved cable management from Version 1.0 -Greater efficiency -Eco-friendly modifications Motor & Drivetrain I mounted a single Grin all-wheel-drive motor in the rear axle for superior climbing power. To accommodate it, I modified the frame from 74mm to 100mm (plenty more modifications coming—Version 3.0 is in the works!). The motor is limited to 1,100 watts, which provides more than enough torque to climb any hill. The slow wind 20-inch setup delivers surprisingly powerful torque. Currently running a 16-tooth sprocket on the disc side*, this hints at the direction for Version 3.0! Cable Management & Protection All cables and the controller are tucked into the footplate, which I restored from another scooter I built (the "Mountain Scooter," now under construction but not yet featured on the Grin website). Every cable, connector, controller, and battery is protected by repurposed inner tubes from old tires I saved after fixing flats. A bit of black paint refreshes scratches on the paintwork and footplate, and Gorilla Super Glue holds the protective rubber in place, it sticks supprisingly well on tube! making installation of salvaged tire tubes incredibly easy. Tires & Braking I installed two Continental Urban E-Tires, maintaining the excellent puncture protection of the wider Schwalbe Super Moto X tires while gaining better range without additional power consumption. Without a rear disc brake (it uses rim brake + regenerative braking plus a hydraulic front brake), the scooter operates completely silently. What's Coming in Version 3.0 (other frame, this one stay the efficient scooter) I'm currently designing a new highly modified yedoo frame to convert this motor into a Stokemonley-style mid-drive configuration. This will allow me to lower the motor gearing for pulling trailers and land work—moving dirt and rocks efficiently. The end goal? A 2-wheel ATV with 2.6-inch Maxxis mountain tires! Stay tuned for Version 3.0! 🛴⚡

VéLorean, Bike to the Future! A Side-by-Side Solar Tandem Quad

2026-08-19 | 27 views

The VéLorean is a hand-built, two-person solar-electric pedal quadricycle inspired by the DeLorean from Back to the Future. It was designed so two people can pedal side by side, talk naturally and share the same view, while four wheels, a low centre of gravity and easy-access bodywork provide stability and confidence for riders of different ages and abilities. The vehicle was designed for the 2026 Sun Trip AURA adventure and the tandem team of Olivier and his mother Chantal, aged 72 and living with a neuroendocrine tumour. Their challenge was to travel 1,300+ km, in two weeks, across the Auvergne and the French Alps, with 20,000+ metres of climbing, using only their legs and solar energy harvested from the sun, powering two GrinTech MAX45 motors (one in each front wheel).

Fahrradgespann, Fahrrad mit Beiwagen

2026-08-15 | 945 views

Ein Paar Daten: - Innenraum über 2m lang - ca. 280WP Solarpanele montierbar - Stahlrahmen - 2X Grin All Axle Motor mit Phaserunner Regler - Rohloff Speedhub 500/14 - Marzocchi 888 Gabel - Lenkungsdämpfer - GFK Boot - 20st. in Epoxy vergossene Akkus 10S unter dem Boot - Kompressor bis 10 Bar - 8,4L Druckluftspeicher - Musikanlage - 168kg :O etc.... Das Fahrrad habe ich mir selbst gebaut da es noch kein Fahrradgespann in dieser größe gibt um viele schwere Lasten zu transportieren. Ein weiterer Grund für dieses große Fahrrad ist das ich gerne Modellbau (Auto, Heli) mache. Mit dieses Gefährt kann ich dann einfach alles einladen und losfahren ins Feld zum Modellheli fliegen oder zur nächsten Baustelle zum Modellauto fahren. Gespann fahren ist etwas ganz anderes und nicht mit einem Zweirad vergleichbar. Gespannfahrer sind von einer Art Virus befallen :)....

Cargo Bomber

2026-08-13 | 30 views

A long range semi-modular do it all bike boasting 70-150+ mi of range. Powered by either one or two LifePo4 Batteries and a QS273 with Statorade. It's heavy, ugly and constantly bashed up but it serves as a daily driver and test bed for new ideas and projects. I'm always tinkering with it and recently have made some quality of life changes. It's capable of hauling 700+lbs, has been range tested for 146 miles averaging 17-20mph before ending the test as I was unable to kill both batteries after 8 hours of runtime. It has a hitch receiver for making new attachments and hauling trailers, 12v sockets for powering tools, onboard air and some other redundancies built in. The long wheel base and lower center of gravity makes it pretty stable and it rides very well in wet conditions and winter.

Smithy Bateira V1.03

2026-08-13 | 23 views

This bike was inspired on the Cannondale Hooligan. I needed an urban bike that was quick and easy to manoeuvre around traffic and get in and out of the train. So I asked Chris from Smithy Bikes to build me a steel frame from scratch and I've integrated a two wheel drive system with your parts. The dropouts were adapted to use 4 torque arms. It weights 18kg, combined with Schwalbe Billy Bonkers and downhill Magura brakes, this bike is a lot of fun!

The Honey Cycle, A 3WD Solar Recumbent Tandem Trike

2026-08-02 | 184 views

Last year my wife and I used this modified TerraTrike Tandem Pro to cycle 400 miles across Iowa with 10,000 other bicyclists during the annual RAGBRAI ride. At that time I had it set up with a rear V3 All-Axle hub motor for cruising and regen combined with a BBSHD crank drive for hill-climbing. The crank drive proved to be hard on the Tandem Pro's complex drive train, so this spring I swapped out the crank drive for one of Grin's new dual side-mounted All-Axle motor kits. Now we can easily climb up the steepest hills in Ithaca NY at over 20mph. This build uses three batteries, three controllers, and three motors. I used two Y-splitter cables to connect all three controllers to one Cycle Analyst. I also have a reverse switch connected to all three controllers. The Honey Cycle carries two 200 watt solar panels and can cruise at 15 mph on level ground using about 400 watts, so that on a sunny day we can arrive at our destination with full batteries! The Honey Cycle represents what I hope will become a new class of lightweight solar-powered EVs. The automobile industry has failed to make EVs lightweight enough to be solar-powered. So it is up to us ebike hobbyists to scale up bicycles and add solar panels to them so that we can give them car-like utility and in so doing save the planet. August 2026 update: I've added a Surly Bill trailer to the Honey Cycle for extra cargo capacity and also to carry a third solar panel so that all three batteries can be charged at the same time.

Pinion gearbox commuter with Max45 single speed

2026-06-12 | 112 views

This is my dream build commuter for the hilly and wet pacific northwest. To achieve some fast average commute speeds, I discovered that traditional gearing was not going to cut it. Having spotted the Max45 with singlespeed was possible for 148x12 boost dropouts I started researching bike packing/mtb frames that have pinion gearboxes. This led me to deciding on the Priority Bruzer as the platform for my project. With that decision made I then ordered up the necessary Grin kit to take me to the finish line. Utilizing the amazing resources on the Grin website ("Motor Simulator" and "Trip Simulator") I figured out what voltage battery (and capacity) was necessary for my fast commutes, as well as what winding I wanted in the Max45. With that analysis complete I ordered up a Max45 singlespeed kit with STD winding, a CA3 and Phaserunner. Battery choice was a 72V with a needed capacity of around 1.3+kWh's. Searching around I sourced a 72V 20Ah battery in the triangle form factor with good quality Samsung cells.

e-Quest

2026-06-07 | 114 views

Human-electric hybrid tricycle. I have added pedal assist to a pre-owned carbon-fiber Quest velomobile. The purpose of this project was to create a practical and efficient vehicle for most of my urban commuting and errands, along with the occasional out of town excursion. I wished to exploit the advantages of a fully faired vehicle to safely increase my low-impact travel relative to using my recumbent bicycle. The reduced aerodynamic drag results in significantly less energy required to travel on level ground, especially at speeds exceeding ~14 mph. The 3-wheeled "tadpole" configuration will keep me upright when surfaces get slippery, and the fairing provides additional protection from the weather and certain kinds of crash injuries. The added weight, however, requires the addition of electric pedal assist, mainly to maintain safe minimum speed on uphill sections of roadways shared with automobile traffic.

After about 35 years of ownership and untold thousands of miles I decided to give my ‘83 ST500 a refresh, and to give my old damaged knees a break I went on to add an eZee front hub motor. I just retired and want to do some touring. I hope you like it! Getting parts was a long story which I’ll spare you, but now the only original components are the frame, seatpost, and derailleurs. eZee front freewheel, 48V 19Ah battery, Fischer AG BB. With the CA3 dialed in it feels very natural, even with assist maxed out. With low assist (about 0.7x, just enough to keep my knees from yelling at me) on a rails-to-trails path, unloaded I made 44 km using only 3.1 Ah. In a couple of months I plan to be in the mountains to see how far I can get when geared up for a tour. I’ll be happy if I can make 50 miles, if not I’ll start thinking about a solar trailer.

Tern Cargo bikes (2 bikes)

2026-05-05 | 107 views

We are gearing up for adventures with our daughter on our Tern Short Haul cargo bike. We've converted it using a CA3+ controller paired with a Phaserunner, driving a Grin All-Axle front motor. We left the rear hub free for future upgrades, such as a dual-motor setup or an internal gear hub. Our primary goal was absolute reliability. To achieve this, we took extensive waterproofing measures: • CA3 Controller: Every crack was sealed with marine silicone. • Phaserunner: Housed in a sealed, outdoor-rated electrical box. • Connections: All connections from the CA3 are enclosed in a sealed box to protect against water ingress. • Motor Exit: We applied liquid electrical tape at the motor cable exit point (supplementing Grin's already excellent factory seal) to make the setup 'bombproof' and highly resistant to salty sea air. We are currently running our older 48V Retention 19Ah batteries (strap is to remove play on rought terrain and white tape to help the battery stay cool under summer sun), which have logged over 8,000 miles. Thanks to the statiator charger, they still charge like new. Our plan is to upgrade to LiGo batteries next year to really make this bike fly! More photo incoming

Recumbent tandem with dual motors and automatic tilting of solar panels

2026-04-30 | 113 views

A solar-powered tandem built on the basis of an Azub Twin, equipped with two motors: a Grin all-axle direct-drive motor at the rear for regenerative braking and a geared eZee One motor at the front to assist on climbs or when carrying a heavy load. Each motor has its own PhaseRunner controller and is controlled by the rear motor’s torque sensor via a dual WP8 splitter connected to the Cycle Analyst. They are powered by a DIY battery pack made up of 14S x 10P 21700 cells instead of the 18650 cells typically found in bike battery packs (52V, 53Ah). Its peak current of 80A allows it to power both motors simultaneously. Two solar panels of 235W each are automatically oriented using a linear actuator. Instead of using light sensors, a 9D sensor featuring a magnetometer, accelerometer, and gyroscope was used to determine the bike’s orientation. Based on the time and position obtained via GPS, a program on an ESP32 board calculates the sun’s exact position and the optimal orientation of the panels. Rotation occurs only if it results in a sufficient power gain.

Bike Friday Tandem with some tech upgrades

2026-03-18 | 170 views

I mainly wanted some help on the hills, plus regen for long descents to save the brake pads. Everything bar the battery is from Grin (All-axle motor, Baserunner, Superharness, Display). The battery is an Infinite Battery which I "should" be able to travel with by air as it easily disassembles and the cells can be taken as carry on luggage. I also upgraded to 1x13 drivetrain with wireless derailleur which really pushed some tollerance limits. The amount of power far exceeds my expectations. Flying up a 20% gradient on a tandem is no mean feat, but this thing does it with ease. The regen however is limited by the max amps of the battery (8A) so I still need to use the brakes at times. We comfortably get 100km on a single charge, but could opt for more or less depending on the level of assistance. All up it's been a very successful project.

Learned plenty adding a G311 Front Minimal Kit to my Pelso Brevet recumbent. I love riding this comfortable, fast, beautiful recumbent but my aging body needed some help climbing the steep hills where I live, not to mention long mountainous climbs on tours. Improvised hardware store items plus the Grin torque arm to the brake fitting on the carbon fork with no eyelets – not elegant but functional! Wanted to mount the battery behind the seat but it didn’t fit frame mount works fine. The Z9 controller is mounted on the back of the seat. Went 1x and added the grip throttle. Note use of cable raceways.

Year-round family commuter & snow plow

2026-01-09 | 194 views

This is our grinning Circle Morpheus serving as a super flexible car replacement. Gets our growing little one to/from school in -15C and +30C warm and dry. Gets me to/from work on my 25km commute. Shovels our driveway and neighborhood sidewalks when it's snowing. Pulls groceries/stuff in a cargo trailer and play date friends in a chariot. We used this bike with a box&canopy configuration when our kid was a few months old and went to daycare that way. Around 2-3years old, she was in a rack mounted seat in the back, with my partner on the front - so the whole family was on one bicycle. And now, kid is in the front until I'm retired and she captains the bike for me. Heated handlebars, pogies and fairing in the winter. Snow plow removable. And soon a secondary bike computer that talks to the CA3 and estimates time of arrival at work for me, based on my actual speed.

Papa's Piecemeal Cargo

2025-10-09 | 297 views

This build began with the acquisition of a Trek MT200 in 24”, of unknown year. It was affordable, about 15 bucks IIRC, and the main frame section appeared geometrically ideal for a cargo build I had in mind. I have an on-site ‘parts department’ (see image), which usually supplies me with nearly anything additionally that maybe needed for builds, except electronics – which always arrives promptly at my front door from those good Canadian folks just north of me…. Grin Technologies. The Trek’s rear seat and chain stays were first surgically removed, then the wheelbase was carefully stretched to 1346.2mm (53”) to accommodate a cozy home for two, fat EGO batteries (which helped to optimized the weight distribution). I then mounted a vintage 26” SID Rock Shok suspension fork, which netted me a near perfect 16-18mm of positive trail. For rubber, I opted for an 24” (507) front wheel w/Schwalbe 2.15 Big Apple. The 20" (406) rear rim is laced to a Grin's GMAC 8t hubmotor, and is fitted with a W/Schwalbe’s 2.60 Pickup tire. I still need install a fresh BB7 front caliper, install lighting, and tidy-up some of the wiring. I’m technically retired (whatever that means?), and posses a couple of deer infested, remote acres just west of the Clearwater NF. Elevation is almost exactly 3000 feet at my living room floor, which,.. had it not been for the windy 12 mile and 1800ft. elevation gain from town to my front door, I’d have zero complains. By car, it’s a piece-of-cake of course, but... I no longer drive most 4-wheeled, highway vehicles. I am also completely off-grid, approaching nine years now, and solar is my transportation’s only refueling source. ~papa~ Thank You Justin & Co.

Brompton G-Line Rear All Axle SLW SuperH conversion.

2025-09-16 | 381 views

The new Brompton Gravel bike with 20" wheels (AKA the G-Line). Converted to a 11 speed cassette and derailleur using a kit supplied by EerderMetal in the Netherlands. A Em3ev 52v 17Ah battery is mounted in the front bag. This bag was also manufactured by EerderMetaal. A Slow-Wind All-Axle SuperH kit was my choice because I don't need a high top speed as we are limited to 15.5 mph here in the UK, this motor has a good bit of torque for pulling my trailer up steep hills. Trailer from RadicalDesigns in the Netherlands. The torque arm bracket was the most challenging part of this build. A DIY custom CNC stainless steel bracket that slotted underneath the rear disk brake calliper did the trick, the torque arm was cut to shorten its length. The bike stills folds nicely. The only downside to this build is that it's heavy. The bag, battery and bike now weighs 27kg! It rides lovely, it's smooth and easy to pedal with PAS set to Zero, no noticeable motor resistants.

Second Wind

2025-09-09 | 354 views

I've grown tired of using my car for everything and I wanted to explore how I could use an e-bike for errands and commuting. This bike is actually the second attempt at making an e-bike, as the first bike had a lot of problems regarding the frame's compatibility with components. I got tired of fixing it and decided to transplant the e-bike stuff onto a new frame. This new bike handles all local trips easily, plus it fits in the bike racks on Translink buses. To commute from South Surrey to YVR, one way is ~11km of riding and $2.70 for the bus fee. This whole project has been about a year in the making and I've learned a lot. Big thanks to my friend Albert at Grin for helping me with this project!

"GrinWagon/BadWagon v3" Converted Radwagon 3

2025-09-05 | 330 views

This Rad Power RadWagon v3 arrived as a donation after suffering catastrophic motor failure — the original factory motor tore its power cables out due to reverse torque and lack of proper maintenance. Working with @alnwright, we decided to bring it back to life with a complete @grin_tech conversion, giving it new functionality and extended service life. Rebuild Configuration: Motor: Grin RH212 direct-drive hub motor – durable, regen-capable replacement for the failed stock motor Controller: Grin Baserunner – integrated with modular wiring for clean installation Display: Grin Cycle Analyst V3 – full programmability, regenerative braking setup, advanced ride metrics Battery: 48V lithium pack (paired with Cycle Analyst for monitoring and tuning) Upgrades: Custom rear footboards (installed by the new owner, Grant) for passenger/cargo use Performance & Functionality: Full programmability via Cycle Analyst, including regen braking and custom ride profiles Increased durability compared to the stock Bafang-based system Utility-focused setup ready for heavy cargo and family hauling Estimated build value ~$3,500 if replicated for resale Now nicknamed the “BadWagon” (or GrinWagon v3), this rebuild proves that older RadWagons can be not only saved but improved. It’s ready for daily use — from hauling kids to school to errands across Boston — and stands as an example of how Grin systems can give second life to failed factory e-bikes.

The Big Bike

2025-08-27 | 524 views

This is my Big Bike, an electric cargo long tail bike I've had since 2011, and was likely the first electric cargo bike in my hometown of Melbourne Australia, it is the OG. Over the years it has been through many iterations, it started as a normal cargo bike and was electrified in late 2011 with a 48V front drive 9C motor. It ran for many years as my work vehicle of choice, it is amazing how many place it gets into, no need to find a park, just ride to and roll up exactly where the job is. There is even a built in work bench! And it carries everything. It was also one of the first Kid movers, and my three boys would ride on the back, those were some amazing days with memories we all remember as they grew up with school pickups and drop offs and trips here and there. When they were big enough to ride the Big Bike would often double duty as the kids bike hauler, they would ride and then have a rest with the Big Bike hauling their rides. Not long ago my youngest boy rode it! It has also been a regular contender in the #carryshitolympics its always fun to see how much stuff can be packed aboard! An interesting not is he bigger the load, the more stable it is. It has been through a few iterations, and not much remains apart from the frame and saddle bags that are original. In January 2025 the Big Bike underwent a modernisation process re-powering it with a Grin fitout. I am a fan of the hub motor for this application, in terms of general reliability, less moving parts and in this application the heavier front wheel balances the overall bike better - an experience observed which hasn't been widely documented for long tail bikes. The overall electrical spec is: - 60V 20Ah LifePO4 battery built with headway 38120S cells and Daly Smart BMS - Grin All axle standard wind front hub motor laced into an Alex DM18 rim, it uses a V brake on the front - Phaserunner - Cycle Analyst with MFS switch and rotary pot control - ERider T17 torque sensor - AYUP Quad front light for illumination and SUV repellant, runs a step down DC/DC converter from the CA I am overall amazed at the quality, documentation and support Grin has for a product range that is overall spot on for the seasoned bike builder. The little things have all be thought of, such as the wire quality, the extras the hardware, the connectors, pinout documentation, how to videos, the software to diagnose and adjust settings etc etc. One thing about the All Axle that was the thing that sold me was the Torque Arm engineered into the design. No more flat spindle spin out. Riding the bike for the first time I was blown away, apart from being silent, I could hear the rubber clawing up the first hill! The torque was just delivered to conquer the local hills. Then add the torque sensor and configuration in the Cycle Analyst and for the first time since the bike was new it became a bike that could be ridden, because pedalling was now responsive and could be enjoyed. It was the start of a journey that I hadn’t seen coming and learning to love pedalling the Big Bike has changed my life almost completely. I’d watched Justins videos and read the writings however the experience of the regen is fantastic. Back pedal for brakes is like the old days in the 70’s, squeeze the ebrake and it kicks in – victory! Control a decent with clicking the assist down – this is incredible. And then there is the maintainable impact, before I’d be changing brake pads every 700-900km, now I have done nearly 5000km on one set of rear pads. There is also another thing with the regen which I haven’t seen or read much about and that is how it helps with interval training. Its possible to keep the speed low for an effort for safety and also to preserve the available trail, something I would never have thought. These days the bike runs lots of kms, with generally 50km in the daily commute that includes 550m of elevation gain from the hills at the beginning and the end. It carries everything including all winter inclement clothing, tools, water, food, charger groceries anything that may be needed on the day day. It is the true car-replacement and a core part of my life. Thank you to Grin and all the team for letting us have the nice things.

Yedoo Scooter project Dual motor high Range

2025-06-03 | 430 views

Updated: This was my first dual-motor project—huge thanks to the Grin team for answering all my questions! I built these two e-scooters with high fun, portability (bike rack compatible), and long-range capabilities in mind. With dual 21700 battery packs, I achieved a tested range of about 80km** on steep hills roads, even at 2°C. The front motor is a Grin All-Axle Slow Wind, powered by a Phase-runner V6, while the rear motor is an SAW20 with a 74mm axle width, capped at 400**watts for that extra push on the many steep hills in Quebec's northern regions. As shown in the picture, I can pull my kid in the Thule full-suspension trailer (about 50 pounds total) while maintaining a solid 18-22 km/h** up an 8% grade hill. I've created a custom rack to hold both battery at the same time as seen in on of the photos, because carrying the extra battery in a backpack was really getting heavy on those long ride. I’ve decided to hold off on adding solar for now, since the components I need aren’t available in Canada. I’ll revisit that option next summer. In the meantime, once Grin has batteries back in stock, I plan to upgrade from 48 V to 72 V. The 48 V pack delivers plenty of power when fully charged, but below about 50 % its output falls off sharply—and with a heavy load (kid trailer in tow), big hills become impossible. The switch to 72 V isn’t about gaining top speed it’s simply to keep the power more consistent across the entire charge range. At least its the ideal.

For my participation in the Sun Trip Sahara 2024 I built a bicycle camper with a Grin drivetrain. I had a really nice trip, the entire route was 7'376 km in 43 days. I consumed and charged about 70 kWh and the average daily performance was 172 km. Unfortunately I had problems with the gears of the Shengyi motor in Taroudant, Morocco. Grin sent me some spare gears within 3 days, so I was back on track unexpectedly quickly. Thanks a lot, you really saved me there! I am currently reworking the vehicle, especially the change to the Grin All-Axle motor will bring some improvement for the next trips.

Silver Bullitt

2025-03-05 | 543 views

The first time I rode an ebike a few years back, I immediately fell in love and didn't want to drive my car any more than necessary ever again. What started with a no-name ebike from Amazon, took me through two DIY builds, hundreds of miles, and a broken arm before going for my end game year round car replacement powered by Grin and based on a Larry vs Harry Bullitt frame. The Silver Bullitt is a dual FH/RH212, dual Phaserunner, single Cycle Analyst build currently powered by 2x 29ah 52v batteries. The frame is a Larry vs Harry Bullitt in raw aluminum finish rated for just under 400lbs/180kg of cargo carrying capacity. The torque provided by the dual Statorade cooled FH/RH212 motors combined is more than enough for the heaviest of loads from Costco/Lowes without overheating, while the dual 29ah 52v batteries provide more than enough range for multi day/week bike touring. A Grin Aux Pot and CA MF Switch on the handlebar makes adjusting the max amps/speed and more a breeze on the fly as riding conditions or as my use case changes between rides. When paired with an 9ft long DIY aluminum trailer, even a Ford F150 has nothing on The Silver Bullitt when it comes to getting work done and looking good while doing it! Summer 2025 will bring with it the completion of the year round camping trailer, along with 300w (possibly up to 600w) of solar panels to extend overall range/time between charging around town, on the trail, or to provide power once at camp. Additionally, a Cycle Analogger with GPS is in route to provide detailed performance information over time for future adjustments and fine tuning the overall setup. For year round riding comfort in the coldest of conditions (we don't get tons of snow but it still gets pretty darn cold here sometimes), the bike also has the ability to plug in 12v DC powered heated jacket and pants via a DC-DC down converter. Once fully complete, The Silver Bullitt will also have turn signals, additional wired headlight, switchable flood/off-road lighting, Apple CarPlay, bluetooth speakers, and a few additional 12v DC "creature comfort" accessories. Thanks so much to everyone at Grin for making this possible with your awesome selection of products, support, and extensive documentation!

Low maintenance year round commuter

2025-03-02 | 437 views

After riding a number of winters with my "90's mountain bike transformed" (https://ebikes.ca/projectgallery/90-s-mtn-bike-tranformed-ottawa) and having to replace the chain & cassette every spring and occasionally chainrings not to mention constant rim brake adjustments, I was looking for a more maintenance free setup for winter commuting. After a bit of research I settled on a new Trek District with the low-maintenance Gates CDX belt drive system with an 8-speed Shimano Alfine internal geared hub and disk brakes. For the ebike conversion I went with a Grin All-Axle front wheel build, Phaserunner controller, simple 24 Pole PAS system, CA3 (of course) and replaced the dynamo light with the Roxim X4 light. This was my first direct drive motor and I was looking forward to trying out the backwards pedalling regen braking. I have to say the regen braking is really sweet and the belt drive with IGH make this a very nice low maintenance setup. Gotta love all wheel drive in the winter! (But some days there is just a bit too much snow!)

I wanted to build fast, comfortable and simple vehicle for long distances, so moving bottom bracket recumbent seemed like a good start. I made the steering geometry (rake and head angle) adjustable to study the magic of bicycle stability. The rear fork has been safely frozen since the first winter, but the steel beam frame and hammock type seat make the ride really smooth. Under the paper towel dispenser box I have a 1600Wh prismatic Lifepo4 battery feeding Phaserunner and All-axle on the rear. I sometimes miss my diamond frame if the snow is really deep, but studded tyres with electric motor make winter cycling really comfortable. Just need to remember to pedal hard too to stay warm!

eXtracycle Electric Cargo Bike

My beloved electric Xtracycle FreeRadical (eXtracycle?) longtail cargo bike electrified using a Grin kit. I finished the bike in August of 2023, and have since ridden ~3500km through ~1.5 winters. I use it for almost all of my transportation needs, from grocery shopping to towing other bikes! Motor: RH212 Controller: Baserunner V6 Battery: 50.4V 19.6Ah, 14s4p using Samsung 50E cells inside a custom rack mount enclosure Display: Cycle Analyst V3 I typically get anywhere from ~7 to ~12 Wh/km with the current setup, depending on throttle usage and PAS settings of course. Future plans include powder coating the FreeRadical black, switching to a triangle/downtube battery, and maybe switching to an All-Axle motor. I've included a short overview video covering the bike in a bit more depth, and plan on making a few more showing my wintertime commutes as well as the towing capability in more detail.

After a number of years of coveting, researching and regularly visiting ebikes.ca I finally decided to take the plunge in March 2018 and purchase an eZee Front wheel kit for an old 1991 mountain bike that I had as a second bike. The near 40km commute (usually against the wind) would leave me quite gassed some evenings and more so towards the end of the week. I'll never forget the grin on my face that first ride to work in April 2018 once the route to work was clear of snow. I was still able to get a workout, but was able to shave 20+ minutes round trip off my commute with the electric assist. The purchase of studded tires made it my AWD vehicle for my winter commute. Throttle only for now, but love the CA3 cruise control feature.

Judy's Pink Pedals Fatbike

2025-02-04 | 461 views

It was with great anticipation that I awaited the coming of the Grin All-Axle fatbike motor. Over a year ago my wife Judy bought this Salsa HeyDay and I promised to motorize it for her. (It's pretty difficult to ride up the hills here in Ithaca without electrical assistance.) I've done fatbike builds in the past and a huge issue has been that typical fatbike dropouts are not strong enough to hold a motor powerful enough for a fatbike, especially if regen is desired. The motor will eventually pop out of the dropouts at the most inconvenient time, often tearing out the motor wires in the process. Grin has solved this problem by creating a very powerful fatbike motor that works with a through-axle bike frame rather than dropouts, and has an integrated torque arm. Thank you thank you!. For this build I used a 72v battery from Electrify capable of 50 amps continuous, so up to 4,000 watts of power. But Judy doesn't actually want that much power so we limited the bike to 2,000 watts. In this photo you see Judy's custom pink pedals and she is in her winter gear with ski pants, ski goggles and battery powered heated gloves. The bike has studded tires (it took me several hours to insert over 200 studs!) so it works well on any terrain including ice. I turned on Grin's back-pedal regen feature and Judy loves it.

Badass Cargo Bike

2025-02-04 | 686 views

The original purpose of this build a few years ago was to create an ebike capable of carrying an adult passenger up a steep hill, specifically Hook Place in Ithaca NY which is two blocks long and has about a 15% grade, and is where my future wife Judy lived. A side effect of using a big motor to carry a lot of weight up a hill is that the bike can also go incredibly fast, and hence the name "badass". I started with a Surly Instigator that was on sale. Surly designed this unusual steel-frame bike to have a downhill geometry, so it is especially stable at high speeds and has really great long reach front shocks. To this I added an Xtracycle Leap cargo bike extension and the largest Grin hub motor then available, a Crystalyte Crown. To help the hub motor at slow speeds and on extreme uphill climbs I added a BBSHD mid-drive motor. This dual-rear-drive setup works very well and I encourage other ebike hobbyists to try it. I use the two motors like two different gears: the mid-drive in low gear is for going from zero to 20 mph, and I kick in the large hub motor for going from 20 to 40 mph. I've gone through several controllers for the hub motor. Currently I have an 80 amp controller paired with a 72v battery capable of 50 amps continuous. Unfortunately unlike the Grin Phaserunner this off-brand controller is not easily configurable so the motor growls at low speeds, but I've grown to like the badass sound it makes. I've configured this bike for winter use by adding Schwalbe Ice Spiker studded tires and Bar Mitts. The heaviness of the rear hub motor is actually an asset for winter riding as it provides more traction. I use this bike for all-weather hauling of my weekly vegetable share from a barn about five miles away.

Year-round commuter E-bike

2025-02-03 | 645 views

his is my first e-bike, which I built from scratch in 2020. I was inspired by endless-sphere.com and the Grin YouTube channel. Initially, I had planned to buy a ready-made e-bike, but every model I considered seemed too complicated and difficult to repair. So, I asked myself how much it would cost to build an e-bike with the best available components. A rough estimate showed that this would be only half as expensive as a conventional, ready-made e-bike – that was the impetus for my project. My design specifications were: • Simple mechanical and electrical construction • Climbing ability of up to 12% • Should not get stuck in streetcar tracks These specifications limited the selection of components to be used. I decided on: • A direct drive motor • A frame without suspension • Mechanical brakes (no hydraulics) • No gear shifting Since I wanted to use a direct drive motor, I looked for a frame that could accommodate not too big wheels, i.e. 26 inch. The Surly Troll, which is no longer in production, turned out to be well suited. It fits tires wide enough not to get stuck in streetcar tracks. I did some actual measurements, and it turned out that 2“ wide tires (or wider) will do fine. After numerous simulations with the Grin motor simulator, the MXUS XF40 hub motor emerged as a suitable drive due to its relatively high efficiency at road gradients of 12%, despite its high weight of about 10 kg. However, if I had the choice today, I would opt for the Grin Fatbike motor, which offers similar performance to the XF40, but weighs only 6 kg. Some problems only arose during assembly: Although the MXUS motor has a mount for disc brakes, it turned out that there was not enough space between the motor housing and the frame to install a brake disc without the caliper rubbing against the motor housing. This issue seems to be known many other users report similar difficulties in forums. Fortunately, I had ordered rims that were also suitable for rim brakes, allowing me to install a V-brake. In hindsight, I would say that this is even the better solution compared to a disc brake. Most braking is done through the regenerative motor brake anyway, and to come to a complete stop at a traffic light, I usually use the front brake. The rear V-brake is rarely used, and the brake pads have not needed to be replaced after 16,000 km – not to mention the rim itself. Since non-existent components cannot break, I opted out of a gear shifter. The missing torque is always provided by the motor. I calculated on the website www.ritzelrechner.de that at a speed of 25 km/h – the maximum speed for non-registered e-bikes in Switzerland – and a desired cadence of 85 RPM, a chainring with 44 teeth and a sprocket with 17 teeth would fit well together. From the mechanical diagrams of the motor and a BMX freewheel sprocket, a chainline of 48 mm was determined. To achieve this chainline at the bottom bracket, I combined a "John Wayne style" 3x chainring set with a relatively short bottom bracket. I kept only the outer chainring and mounted it in the middle position. The electrical components include: • Battery from EM3EV • Phaserunner PAS and Cycle Analyst from Grin. Now, almost five years and 16,000 km later, it’s time for an update. Although my e-bike was meant to be as low-maintenance as possible, especially after the first winter, some repairs and conceptual changes were necessary. Initially, this concerned the brake levers. I originally installed brake levers with electrical contacts that could trigger regenerative braking support. However, this brought some disadvantages: The quality of the e-bike brake levers was nowhere near comparable to normal brake levers. They were wobbly, the lever arm was too short, and the brakes had to be adjusted very precisely. Additionally, there were winter problems with coupling mechanical and regenerative brakes. When I parked my e-bike outside for a few hours, the battery temperature dropped so low that the BMS prevented charging. This caused the electronics to stutter when braking. The solution came with the CA firmware version 3.2 beta in the form of a virtual backpedal brake. Now the mechanical brakes and the regenerative brake are decoupled, and as a welcome side-effect the cable from the brake lever to the Cycle Analyst is no longer needed. Other changes concerned weather resistance. In Switzerland, aggressive potassium chloride is spread in winter, which caused my chain to be completely degreased after only one ride in the salt, and even the BMX freewheel was damaged. After various attempts to better protect the chain, I finally discovered a fabric chain guard. This type of chain guard has been common on Dutch bikes and already seemed old-fashioned to me in my childhood. However, old-fashioned does not have to be bad – quite the opposite. With a pair of scissors, this chain guard could be easily adjusted to expose the crank, the opening for the PAS, and the area next to the sprocket. Thanks to the fabric, the chain box does not form a resonance chamber, and the significantly reduced chain wear eliminates rattling or scraping noises. Since front fenders are usually too short, I extended mine downward with a mud flap and forward with a cut plastic piece. Previously, rainwater always splashed onto the headlight and the bottom bracket housing – this problem has now been solved. Another improvement concerns the handlebars: I originally installed a downhill handlebar with a 15-degree backsweep. It looked sporty but led to arm pain and cold fingertips in winter, A new handlebar with a 47-degree backsweep brought a significant improvement: no more pain, and thanks to better blood circulation and a better position against the wind, no more cold fingers.

A modified Chinese tailg scooter. Upgraded to include a Grinfineon 25A controller and Cycle analyst for regenerative braking. After returning from a year living in Shanghai. I bought this bike and added a cycle analyst and grin controller. Having regen braking was a huge help due to the fact I didn’t know if I could buy brake parts. I used this bike as my only transportation at the time. Dropping two kids at school and then off to work at the empress hotel during the construction Reno’s. The money I saved on fuel and parking ($18) a day more than covered the grin upgrades. The factory motor was so robust. I never thought to upgrade. I rode in the snow rain, wind. Everyday trouble free. The oven mitt gloves kept me warm and the umbrella kept me dry. People would stare at me everyday.

As a Grin dealer and also a recumbent dealer / specialist it's natural for me to gravitate towards their products for my own projects.

I also wanted to keep as much of the look and feel of the original scooter as possible. So, if you have an old Ego Cycle in your garage and want to do something similar, I’ve made a video to share what I set out to do and why, what I discovered when I went shopping for parts, what I chose to do and how it all went together, and, finally, how it turned out.

Old-School/New-School Do-Everything Bike

2025-01-18 | 697 views

Work, play, summer, winter, my Spot Brand Wazee has been my do-everything bike for a decade. Old-school steel frame, retro styling new-school 11 speed hub, belt drive, hydraulic disks. Bit by bit, it's gone from sporty to utility - fenders, raised bars, a box on the back. A hub motor seemed only as weird as the rest of it. I didn't need gobs of power, and I wanted a clean, minimal appearance. Also wanted quiet, as the belt and hub are so quiet. It worked out, and my goodness the hills and headwinds are easy now! Battery wouldn't work on the teardrop-shaped downtube. Kinda like it better on the seat tube anyway, as it keeps weight distribution a bit more even. Kept the wiring pretty clean using existing zip tie braze-ons. No display, no PAS, no brake cutoffs. Just a throttle and a headlight. Wrapped unused connectors in silicone tape. Got Grin to add the 'battery tap' to the Baserunner so I could add a 5 volt buck converter and USB connectors for the rear light (an LED light strip wrapped around the box) and occasional "festive" accessories. Halfway through my first winter with the hub motor. Salty crap hasn't gotten into anything it shouldn't. Works at -25°C, and front wheel drive pleasantly pulls past poorly ploughed paths!

Unlocked Diamondback Powerline - STOLEN

2025-01-05 | 1067 views

As of December 2024 this bike is gone stolen from my garage. I really enjoyed the results of the effort I put into customizing it. If you see this bike around anywhere, please reach out. It should be easy to recognize because I don't think anyone else in the world has done an external motor controller swap on one of these. Having been an "acoustic cyclist" commuter and road biker for many years, and having been a previous owner of a Specialized Turbo Vado, several Radpower bikes and a handful of Grin conversions, I really wanted to experience a mid-drive e-bike that was similar in experience to a road or commuter bike, but wasn't nerfed by canadian e-bike laws (like my enormously expensive Turbo Vado was). I love the flexibility and power that Grin conversions have given me, but I was too afraid to try modify my Turbo Vado, so I ended up selling it and sticking with geared hub motors (which have served me well!) Then I found this bike on Kijiji and thought it might perfectly suit my needs. I purchased this Diamondback Powerline from someone that had it stolen then recovered by the police, the paint was badly damaged, the wheels had been swapped from a set of 27.5" 10 speed to a set of 700c with a 9 speed cassette so it wouldn't shift properly, the brakes and speedometer didn't work, and the power electronics wouldn't consistently provide power there was even a check engine light flashing on the badly scratched OEM ebike display. I didn't spend too much money so I felt comfortable with trying to modify it without risking too much, and I also felt pretty good about keeping this bike out of the landfill. This bike has a Shengyi mid-drive CMT01N motor in it, and I have replaced the majority of the power electronics with Grin parts, including a Baserunner L10 and a Cycle Analyst, and I really love this thing. I removed the motor from the frame, cracked it open, installed an NTC thermistor on the motor stator, then wired up an L1019 cable to the existing hall sensors and phase wires. I also supplied 5V DC to the torque sensor and measured the output voltage of the other pins to figure out the torque sensing and cadence of the pedals, I then hooked up these wires a standard Grin torque sensor cable and added an inline 10V to 5V DC converter board to make sure it would be compatible with the Cycle Analyst. I didn't have a speedometer, so I bought a cheap one off Ali Express and wired that up into the Cycle Analyst. I also added a super nice headlight (SPL-01 1900 Lumen Ebike Light) from Grin which is amazing at night. I built a 48V battery with a Hailong case, shoved the Baserunner L10 in there, then wired up the Baserunner and Cycle Analyst and configured everything and I was good to go! Everything went fine on first ride, but I wanted to go faster, and the supplied chainring is proprietary, so I thought I was out of luck, but then I realized I could remove the chainring guide and put an additional chainring on (like you'd see in a 2x front DR system), so I slapped on a 50T and I was good to go! I completed the build in the winter, so I didn't really have a chance to test this bike out very much, but I was able to hit 50kph at about 1200 watts in the highest gearing. I was pretty satisfied. Since spring has arrived in Calgary this has been my primary mode of transportation, at least when I'm by myself, and I've put several hundred kilometers on it. I've set the thermal rollback to start at 60C and stop at 90C and it seems to be running great under these conditions. I usually run between 2.0 and 5.0x torque with pedal assist and I find it to be super smooth, powerful and quiet. I can fly up hills with grades about 10-15 degrees at about 25 kph no problem and the motor only starts throttling if the hill is really long. I have been riding fast, and with a high cadence (70-90 rpm) yet I've averaged 9.2 wh/km, which I think is amazing given the aggressive speed and hill climbing I've been doing. The motor is small, and rated at 250 watts, but I have noticed that the motor will handle 500 watts on a flat surface for a long period of time without overheating. It only really becomes a problem when the power levels climb to over 750 watts which typically means steep hills. I really think that 750-1000 watts is reasonable on an ebike, especially with steep hills and carrying large loads. If we got rid of power requirements in the laws and stuck with the 32kph limit I think e-bikes would be much more useful to many people out there, thanks Grin for helping me unlock the true capabilities of this bike! Things that I had a tough time with during this build * Routing the cabling through the frame. I originally tried making the L1019 modular with MT60s and JSTs inside the motor, but that was a bad idea. It is now just a hard wired L1019, which totally makes sense, the L1019 is modular anyway! * Unable to auto-tune the motor. I got around this by loading up an Shengyi SX profile and modifying it to get it to work. Hall sensors seem to work fine, so I'm not sure what I did wrong. * I have a throttle, but when I go throttle only it often has a hall sensor error and shuts off power. I'm going to be removing the throttle since this bike is best with pedal assist anyway. * I can't find 27.5" rims with 100/135 QR skewers for a reasonable price anywhere. I'd really like to have this bike running 27.5x2.25 or thereabouts for a bit more contact to the ground for dirt/gravel trails. I might have to build my own in the winter. Thanks for reading.

Clown Bike Death Trap That May or May Not Be The End of Me

2024-12-01 | 561 views

The origins of this bike is an ebike called Jackrabbit OG, that comes in at 11kg/24lbs from factory with a 300w motor and about 10-12km range from a 40wh battery. Its sold and marketed as a super-light weight fun bike, but can definitely serve a a last-mile commuter. I indeed did a 5km commute on this regularly, with charging at destination and home. It's very light, nimble, fun, but also commands some diligence and caution given the extremely high centre-of-mass, short wheel base (73cm) and twitchy steering. At 9kg it's very easy to sling around. 300 watts was fine for flat areas around the streets, but the slightest gradient really brought out the limitations. There was one particular hill though that made me think "this is unacceptable" and I immediately started looking for more power and range. That brought me to Grin products. With the rear dropouts being 110mm, I used a Grin AA Front motor with some custom spacers and axle. This is driven by the Phaserunner and powered by a custom made 13s3p Molicel P45 battery, made by a Canadian business on the East coast. The rear-only brakes immediately became inadequate and I had a custom front fork with disc made - 20" disc forks are non-existent except for some BMX specific stuff that doesn't fit the look. I swapped in a Magura caliper with a 203mm rotor. The final weight is 18kg which has doubled the weight, but my bicep curls finally have a use-case and I don't find this heavy per se. With a range of about 60km (according to the Grin simulator), it's got a great ratio of weight to range/power. Playing around with the Phaserunner software, 1000watts is fast but sensible, 1500watts requires much more caution on the throttle, and 2000watts feels angry and twitchy. Obviously, hills aren't a problem anymore. The Grin products are extremely high quality, and I struggle to find anything to even nit-pick at. I'm really impressed with all parts of the products, information, documentation, fit and finish, performance. All 10/10. Before I considered Grin I considered the usual suspects - the Aliexpress imports, Goldenmotor, Amazon stuff, and they could only offer lower prices. All other aspects weren't comparable. I've become a huge fan of Grin products, their business model, how they treat their staff, their investment in product development. Their methodical and cautious approach to their work shows in all aspects. I will definitely be considering another motor to go on my next idea - a 29" BMX with a Grin at the back again.

Comotion Tandem Conversion

2024-11-17 | 535 views

A used low mileage Primera was the perfect platform for the conversion. The long, open bottom beam permitted a battery placement with a low center of gravity. The Grin slow wind All Axle rear motor with torque sensor and the recent CA update enabled regen breaking which is absolutely awesome for a tandem. The only challenge was the need to add 4mm spacers to the timing chain side to accommodate the width of the battery. We've put just over 100 miles on the clock and still have 25% on the 48V 19 AH battery. Special thanks to Miguel for his support and patience.

Trek 820 mountain bike meets xtracycle Free Radical and the Stokemonkey. The idea of using a hub motor to create a mid-drive made me smile the first time I saw it. But having the pedals always turn if the motor was running bugged me. I also wanted my next ebike to have a throttle driven by torque sensing of some kind. That's not possible with the conventional Stokemonkey setup. The solution to both problems was a right side drive with a freewheeling crank. Easier said than done, but certainly doable. And as it turned out, Grin was closing out some Stokemonkey parts right about the time I was noodling this over. It took five years of on-again off-again working on it, but it is finally done.

Brompton bike for oversea touring Updated

2024-08-20 | 656 views

I present my first Brompton build, this one was a challenge since cable management is a nightmare on those bike. Plus i don't have fenders to use to place the controller as presented in grin's conversion of this bike. So here it is, its a 6 speed 2023 Brompton that i bought new and converted it into a no fender, single rear brake, single speed, (upcoming Tannus airless tire) and electric, compatible with Dewalt battery and my 900 watt/h Grin Battery. The goal of this bike is a maintenance free, world touring bike and I'm getting there. Its equip with the front direct motor that Grin provide, Baserunner controller, Throttle, CA3 and a torque sensor Erider. I manage around 100km range on this bike. I use the front motor as a brake replacement with the regen so my only mechanical brake is the rear one and doesn't show any major wear even after 2000 KM, thanks to the regen. I use a brompton front bag to hide the battery and i don't even have to take it out to charge as there cable exit for both connecting and charging the battery from the bag, so i can discretely charge it with a statiator in a cafe or something. UPDATE : I've change the tires as after using the Marathon then the Tannus airless, i found that the new continental urban E-Contact plus tire are amazing for Ebikes, I've got more range due to a lot less drag. And remove the battery from the bag since it made my front very heavy due to my 900watt/h battery

Custom LongJohn Cargo bike. Built to commute 25km run per way with 300kg total weight to replace my car trips of the same journey. See trip simulation at end of description which shows just the G62 in the rear*. Based on these simulations and the Grin youtube videos on multi-motor systems, I decided I needed an additional motor up front. 1300kms of test riding in prototyping stage. Finished up and painted now (May 2024) Getting about 21 wh/km doing 35-40km/h on the simulated trip (with dual motors). Front motor comes in under moderate throttles, with rear G62 starting to assist at 50% throttle and then stepping up to providing the majority of the torque at higher throttles. Front MAC motor limited to about 50 phase amps to help keep its temp down as its also doing the regen. I have a 250W road legal mode that the Cycle analyst resets to if I turn it off. My "Offroad" setting is limited to 80A battery current and 4500W. I'm using the "Power throttle" mode on the CA v3.1. I'm running V3.2b3 firmware that gives back pedel regen and using the throttle to provide proportional regen. https://ebikes.ca/tools/trip-simulator.html?m=MG62_STD&v=cust_ad0.7_rd0.015&ms=300&h=200&w=26&sp=40&wv=0&b=cust_vl65_br0.2&c=PR&rg=true&t=21&ct=21&st=21&i=map&p=&mo=-37_15372+144_23335&md=-37_00486+144_27541&x=&y=&lx=&rx=&rw=

This is my Metrofiets cargo bike, now with a stealthy little ebike conversion capable of regen braking. Metrofiets were designed and built right here in Portland OR, USA and are equal parts style and function. It is so much fun to ride around on such a unique piece of Portland bike history. The motor helps make long rides on this heavy bike less daunting. My goal in the conversion was to give myself a little boost to average speed and do regenerative braking without being too obvious. I also wanted a bike that encourages me to keep pedaling, not just let it do all the work, so I added a BB torque sensor. I think this achieves those goals pretty well and I'm happy with it.

$200 Pawn Shop find. I couldn't pass up a spring sale and an XL frame. Always looking for projects. My first project with Grin worked so well that I wanted to build another one! I now have two bikes for 2/3 the cost because of the bottle batteries that are interchangeable between my two e-bikes. It makes for a more affordable step up. Now, I can ride two bikes on two different types of terrain—one hardtail for roads and one full suspension for trails and stuff. The hardtail allows me to hold more batteries via the two panniers, which is excellent for longer trips. I bought a 3rd battery, an Ezee 48/16ah, for long rides. I like it too( although I popped a 30 amp fuse but learned to take the battery apart). I've had a few doggies try to catch me, and they keep up with me, but it’s always good for staying in shape! Lol. Bear spray might be an excellent defence weapon if you're not cool going over 40 km per hour. Just saying..lol I can peddle to about 45 km per hour, which keeps the dogs and me in shape.

This is an inaugural year Big Fat Dummy frameset I bought on clearance and kept in a box until I adopted it as a Covid lockdown project. After watching a Grin video on multi-motor setups, I got the idea in my head to make it all-wheel drive. And with the help of the folks at Grin, it worked great! (until I ripped out the brazeons I used for the torque arm, which is why some photos only have one hub motor.) I use this as a grocery getter, passenger hauler, box truck, and most importantly it hauls a 4000w soundsystem on Pedalpalooza rides all over the city. Also my little fuzzy buddy Ranger has been riding bikes since he was 3 months old, and is never happier than when he's on the back of the bike.

2021 sanity project rescuing a replacement RANS frame from storage to build a second recumbent high-racer, this time with oomph and range (I may have gone a bit overboard). Lots of Grin Tech made this an easy and fun first conversion project - RH212 direct drive in a built 650b wheel Phaserunner L10 controller Cycle Analyst V3 EBrake WUXD levers ERider T9N torque-sensing bottom bracket... all hooked to a 52V-20Ah battery in a Blackburn frame bag under the main tube. It's fast and probably could go 130 miles on one charge. Weird stuff: Fabricated stainless steel plate for left dropout torque lever bracket - it's bolted to a disk brake boss and a rear eyelet, keeping both usable! Also added a second torque lever on the right side - this is an aluminum frame and that motor has silly power. Mounted the Cycle Analyst vertically for knee clearance. Bulky bags under the seat for hydration system, tools, and rain gear. There's a full front fender and a cropped rear fender under the seat bags. Lessons learned: Go bigger with the rear disk size (at least 180mm) to get more clearance with the sides of the motor! Keep plugging away at the settings until you get exactly what you want. And, maybe avoid installing a throttle - for me at least, too much temptation. Huge thanks for all the fantastic free and well-organized information from GRIN

This started off as a gravity only downhill mountain bike for people in wheelchairs. I have since used Grins single sided 1500w hub motors on each rear wheel, CA3 and baserunners to convert this over to electric! It has been an absolute game changer! Before it was very, very limited to where you could ride this. Even in places that were somewhat downhill, the weight of this made you loose speed very quickly. Also pushing around the pits just to get to the lifts was exhausting. Now, I can ride all day and have an absolute blast with my friends!

Aventon Pace 350 Conversion – Cruiser to Commuter/Touring Bike

2024-05-14 | 540 views

First generation Aventon Pace 350 retrofitted with GrinTech parts. Built to commute to classes while on a campus notorious for its lack of student parking, but now ridden recreationally. I bought the Pace 350 because (at $1000) it was one of the cheapest ebikes I could find from an American bike company, and I wanted to minimize my spending in case riding an ebike to classes turned out to be impractical. Since then, I've probably spent more than $2000 on upgrades and customizations. Battery cradle, brake levers, and thumb throttle are reused from the factory configuration. New electronic components are an ERider T9 torque sensor with Miranda cranks, Baserunner L10 V6 controller, GMAC 8T rear hub motor (replacing a Pace 500 rear hub motor, replacing a stock Pace 350 rear hub motor), and a Cycle Analyst V3. The stock battery, a 36V L440 Reention Dorado, is replaced with a 48V model. Other new non-electrical components include an FSA 50T chainring, RockShox 30 Gold RL suspension fork (replacing a stock rigid fork), Cane Creek 3G long travel suspension seat post, an Ibera bike rack, and SKS Bluemels fenders (since fenders weren't included stock). The seat post adds three or four inches onto the height of the saddle, which is actually slightly too tall for me even when lowering the seat post as far as it'll go. In retrospect, I wish I'd bought the medium size bike frame and not the large. Many components on the bike are 3D printed. A 1000 lumen "Slonik" LED headlamp is locked into a 3D printed clamp that interfaces with a Planet Bike fork mount headlight bracket. The RockShox front fork has no eyelets for mounting fenders instead, the fenders attach to 3D printed clamps tightened around the fork lowers. The first-gen Pace 350 has no eyelets for a bottle cage this bike has a 3D printed bracket for mounting a bottle cage on the top tube. Installing the torque sensor necessitated removal of the original crankset, which had a built-in chain guide. This was replaced with a 3D printed chain guide, a very durable but easily replaceable design that saves ~$20-30 compared to buying one off Amazon. The Baserunner is also zip-tied to the downtube with a 3D printed tube mount. Huge thanks to the guys at Grin for all the tech support they've given me! I've pestered them for a while with all the problems I've encountered, and they've been invariably helpful to me.

ChaseWheel Wheelchair Power Assist

2024-05-14 | 470 views

My friend Matt and I built this power assist attachment for my manual wheelchair using Grin parts: Baserunner, Cycle Analyst with switch, and an 8" scooter motor. The rest of the parts were taken from a used electric scooter. The Cycle Analyst was crucial in helping us pinpoint the sweet spots for the throttle ramping, and the switch allows me to set a soft-limited speed limit for when I'm rolling around busy areas. My DIY "ChaseWheel" has been a huge improvement over the SmartDrive, which is what is currently on the market for motorized wheelchair attachments. I haven't used my SmartDrive since September! The controls are more intuitive, it's more maneuverable, and the battery lasts me 5 days. This project and its multiple prototypes served as my senior capstone project for my degree in Industrial Design, which I graduated from this week! Going forward, I plan to continue developing the battery mount and attachment mechanism for the device, incorporate LiGo batteries once Grin rereleases them, and eventually my goal is to release the plans for it open-source so people can build themselves affordable power assists. This project was my senior capstone project for my degree in industrial design at Rochester Institute of Technology, in collaboration with Matt Meleski from E-Bikes East.

I'm a big guy(320 lbs) and I have a lot of steep hills where I live. I wanted something comfortable and capable and that I could also get exercise with. I originally bought a Ariel Ride grizzly. Capable but not comfortable. I then decided to build my own(first build). I settled on a Day 6 Samson frame. It's a semi-recumbent. Very comfortable seat and backrest. I added 2 frankenrunner controllers, Cycle analyst, 9H front motor(used a rear for 135mm dropout) and bafang(G62) rear. Front direct drive for regen braking. Pushing 2000w in front. 1500w in rear. I have 2 72V 15ah batteries. This comfortably gets me up any hill. Because it's a semi recumbent, I can put my feet on the ground while sitting and still have good leg extension. I added a rear rack which can be in 2 modes. The cases are removable. I have a small case with tools ectera. I also have a big case that holds at 72v 50ah battery for a total of 80ah if I ever needed the range but I haven't exhaused the 2 15ah yet. This bike is a dream. I have my CA programmed for 30 levels of assist so I can attain any speed I want. Not that I need it but this bike gets me to 42mph. Grin made all this possible.

CAT Longhaul Rasta All-axle

2024-05-13 | 472 views

This 20 year old, 50 lbs cargo bike has new life from a minimalist install of a Grin All-axle, hooked up to a Phaserunner that has Dyol throttle directly attached, with no head unit. This system is destined to end up as auxiliary assist on a Tern GSD, which will likely be a more interesting project. While I wait for extra parts to make that come together, I’m enjoying this ultra minimalist set up. I found that I needed to relax the throttle ramping time up to a second and widen the dead zone to make the bike feel chill while I get used to the way the Dyol feels. Having regen from the throttle, especially on a bike with rim brakes, is awesome.

Cetma Largo Mega Hauler Family Adventure Wagon

2024-05-09 | 453 views

I found it on Craigslist, with a Stokemoney, a locally made bike for sale 1000 miles from home. It sat for months, and then I found myself visiting for a short trip. It went into the rented minivan, I rode it to a freight shipper, I shipped it home. The Stokemoney was astonishingly weak at climbing, it may have been set up wrong, it was soon replaced by a Mac motor, Phaserunner V2, V3 Cycle Analyst, a battery from Grin, a bottom bracket torque sensor and a cycle satiator. Part of why I chose the Cetma was because it seemed well suited to being a dual motor ebike. As much as I loved the belt drive and continuous shifting, after 5-6000 miles I decided to finish my original plan of having a dual motor bike that can haul anything up my very steep hill. I wasn’t able to find a shop that would build the GMAC for me, so I used the spoke calculator and tutorial build, and it went amazingly well. For some time I used this dual geared hub motor bike with a battery that could only output 45A, then upgraded to a battery capable of supplying 80A. This finally completed the full dual motor experience and it’s amazing having a hub motor bike that seems to never run out of torque. This has been my daily bike for nearly 6 years and it wouldn’t have been possible without the work Grin does.

Radwagon Phaserunner Conversion

2024-05-08 | 463 views

Conversion of a Radwagon 4 to a Phaserunner & Cycleanalyst setup. This is a heavy two-kid carrier and the stock controller just doesn't provide enough power to comfortably accelerate or climb hills. The Phaserunner fixes that problem, allowing me to run much higher peak power through what remains a legal "500w" motor. The ability to customize power onset and ramping-up is also wonderful. *See the youtube video linked below for a full walkthrough of my customizations to the bike.* -Phaserunner mounted on 1/8" aluminium plate using stock controller mounting holes on the frame. -Parallel batteries, upper one on a Triplebob, connected with Y cable from Grin. -Stock Bafang hub motor -24-pole PAS and throttle from Grin -Shinko tube-type motorcycle tire on the rear: heavy (3.5kg!), high rolling resistance, but outstanding grip and comfort (thick rubber + low pressure). Comfort and reliability are more important than efficiency on a kid-carrier like this.

This frame is by Ventana. We got it over 10 years ago and rode a lot of snow, dirt, and gravel. Now at 60-years old with a bad back I can't do that stuff anymore, but I didn't want to give up riding this beauty. So, we converted her to a street rod and added some sweet Grin e-assist. BEST DECISION EVER. This bike has a rear 170mm Rohloff Speedhub, which I did not want to give up nor did I want to give up our frame specific front fork so the front wheel Grin All-Axle Hub Motor was the perfect choice. Grin is the only company I found that machines their own inserts to fit my front fork. I had the idea to hide the battery in a frame bag and I think it looks super clean, super tight. Given the size and weight of this bike with two riders, I also purchased a second battery. We have yet to try and see how far we can ride on two batteries, but we are looking forward to it. Trust me when I tell you this bike is a head turner. Everywhere we go people stop and ask us questions. I won't be surprised if Grin sells a few more all-axle motors from our free advertising, lol.

If scooters didn’t suck

2024-05-07 | 602 views

This is the second scooter I have built, obviously I love them but the ones on the market are not for me. This is a Globe3T full suspension downhill scooter. I purchased it off Pinkbike out of the whistler ski area. (You can’t buy these in the US they are French) Globe has started to make electric scooters but none this powerful. It is 2 wheel drive powered by 2 all axel hub motors both with statorade and dual phase runner controllers, 1 throttle. I run 3000 watts in the rear and 2000 in the front. I know 5000 watts would never be condoned by Grin, but this really works. The amazing thing is with 2 motors and the lightness of the build, nothing gets hot?!? It’s faster than a modded Sur Ron, and the best part about it is the absolute silent running. The battery is a special 72 volt 140 amp continuous discharge custom build 12 amp hour. This build is thirsty so I only get maybe 15 Miles on a charge. I have been playing with the phase runner suite tuning on this all the time. I am experimenting with virtual free wheeling on the front trying to get it set up to switch from 2 wheel drive to 1 wheel drive to increase range. I have the scooter limited to 46mph, It accelerates like a bat out of hell and climbs all hills. With 2 motors even at slow speed the torque is incredible making technical riding easy. The All-Axle motors are light and the handling is amazing. The build was simple, I did have to mill down the fat tire adapter in the rear to get the correct spacing. Build is about 60 pounds. Lastly, unlike all other small wheel scooters, this thing really shines off road. My buddies ride sur-Rons and they barely hang with me, and I get none of the negative attention they do. I really think I might have the baddest, fastest, stealthiest Grin-powered vehicle on the road? Prove me wrong? It’s dirty because i ride it constantly!!!!

2024-05-06 | 467 views

Front wheel motor, with pedal assist and throttle. The challenge was to find good locations for some of the components (controller and CA3 display). Main use case for me is going up steeper hills where balance at very slow speeds is an issue (safety also, as chugging up blind hills can be risky when there's no shoulder, as is often the case on many rural roads). Very happy with the result.

I found your YouTube channel 2 years ago maybe longer. It inspired me to try a solar trailer for an e-scooter I got for free from fixing other people's stuff. Long story short the scooters are dumb lol it took me over a year to afford the cheapest e-bike kit and a 200$ bike from CT and it reused the trailer and made a solar stand out of steel instead of wood. I just need some better batteries and I'm the lights-disabled Solar E-Biker around lol You can see my build on my YT channel @Ro-Bucks, it's about the only one I got up on there. I wish new of this before. Grin is what got me into all of this. Thank you! I might need to sell this and I just made it but my new issue with range I think is my body now and that now very far. I need a recumbent trike to reduce the stress on my core cause of a rib deformity (Pectus excavatum) and bad back and hip. I now have new plans for my solar setup and I'm building a solar setup for a friend, going to need to get some grin components for spare parts before my big adventure. Wish I had a friend with the guts to ride from Ontario to the grin shop with me but that's a big trip )

My Chopper Pedelec is a big bike, that weighs round about 30kg, depending on the battery size and it offers a lot of space for really big battery packs. So ranges of more than 300km with a single charge are possible. Because of its comfortable seat position riding the whole day could be a pleasure. The legs in front, the body leans nearly upright on a backrest. It is not a recumbent, but neck and hands are relaxed, while riding.

Larry Vs. Harry Bullitt Clockwork Orange

2024-05-01 | 449 views

This is my converted Larry Vs Harry Bullitt Clockwork Orange. My previous and first electric conversion build goals on an edgerunner classic in 2017 were to be a sleeper and pedal assist. The quiet direct drive was hidden in the rear and batteries in the saddlebags. It was unfortunately stolen, but we'd also gone from one to three kids, so before I could make a decision on my next build she ran out and bought an electrified Madsen. But when stuffed with three kids, the 500w BBS02 mid drive definitely left something to be desired on these Vancouver hills. So when a used Larry vs. Harry Bullitt finally came up on craigslist, I immediately pulled the trigger and began converting it. Torque and ease of install were top priority rocking a 1500 W front ezee geared motor. eZee350F_L10 Baserunner Cycle Analyst 48V battery from Grin. Triple bobs worked like a charm. Only thing that slowed down the build was aligning disk brakes and was easily solved with a spacer between the motor and the brake's disk. Next purchase is the new torque arms! I absolutely love this bike. Handling is amazing even when overloaded with three kids!

My Dual Suspension RH212 Rear Hub E-Bike Journey with Grin Technologies

2024-04-30 | 507 views

Hi everyone, I'm thrilled to share my journey of building a custom e-bike using Grin Technologies' RH212 DIY Kit and accessories. This project underscores the significance of investing in quality components for exceptional performance. For my second e-bike build, I set out to create a versatile and enjoyable ride for cruising local cycleways and joining group rides with fellow "ebuddies". The bike needed to provide road comfort with dual suspension, operate mainly on throttle, and run on 52 volts. I carefully selected a Giant donor bike that perfectly met my criteria—29-inch wheels, 100mm front and rear suspension travel, and ample space for a custom battery box. Here's a breakdown of the components used: RH212 DIY Kit including the L10 Phase Runner controller, V3 Cycle Analyst, Thumb Throttle, and CA3 MF Switch. All these components were shipped from Vancouver to NZ by my supportive brother—huge thanks to him! Assembling this e-bike was a rewarding DIY experience, requiring meticulous planning and problem-solving to seamlessly integrate the Grin items. I upgraded to 203mm rotors and installed an e-brake switch (horn switch) to initiate regenerative braking, effectively preserving my rotors and pads. Additionally, custom laser-cut torque arms on each side of the hub motor (10mm and 6mm respectively) reduce stress on the motor shaft during heavy regenerative braking. To enhance the riding experience, I integrated a Grin Pedal Assist System sensor and fabricated a custom 36-pole PAS magnet ring using 3D printing technology. The PAS system has significantly improved my riding style and overall enjoyment, while still allowing for thrilling throttle-only rides. My battery pack currently provides a usable 800 watt-hours. I've achieved an impressive 90km range before cutoff, with a comfortable 35km range using the throttle-only option for fun rides. This project is an ongoing endeavor, with plans to potentially upgrade to 72 volts in the future. I want to extend my sincere appreciation to Grin Technologies for their outstanding customer support. They patiently addressed my queries, guided me through the Phaserunner update process, and helped resolve technical challenges along the way. I'm eagerly looking forward to more exciting upgrades and rides ahead!

Ocean Kite Engine

2024-04-30 | 602 views

This is a hobby that got out of control I'm building a prototype kite controller that converts regular boats into kite boats and wind generators, I chose the baserunner to test with because these motor controllers are designed to integrate human inputs with electric control. This is important for the OKE since it requires a responsive and adaptable control system that can handle gusts and 20+ mph winds. The Grin controller allows for a familiar, bike-like interface that's intuitive for users, providing straightforward controls such as throttle and brake inputs. This makes it easier to manage the complex dynamics of kite propulsion, where precise control over the kite's power and position is necessary to maximize efficiency and safety. Additionally, the Baserunner's robust design ensures reliability and durability, essential qualities for equipment used in maritime conditions. Using this controller, I've been able to enhance the OKE's functionality, making it not only more user-friendly but also more effective at harnessing wind power for propulsion and energy generation.

Cinder Cone high speed commuter

2024-04-29 | 480 views

I turned my old Kona Cinder Cone hardtail into an excellent commuter with a bunch of components from Grin. I think that a barrier for a lot of people who might be interested in converting a bike (certainly me!) is a distaste for protruding clamps, wire bundles and zap straps. I set out to make this bike as close to the slickness of a factory ebike as possible, while still enjoying all the advantages of Grin components (power, customizability, future-proofing, regen braking, throttle and torque sensing . . . ). I got most of the wiring inside the bars, concealed the torque arm, and streamlined the battery mount. See what you think from the photos. It has a 10t Gmac motor capped electronically at 1500 watts (which it easily reaches), a 52 volt battery, Erider bottom bracket torque sensor, and other components explained below. I charge to 85% with a Satiator to prolong the battery life. I can ride at 40-50 km/h anywhere my car goes now, and get to work non-sweaty if desired. I have programmed a fully street legal mode in case of compliance issues, and an offroad mode (which I use most of the time). I think of it as a wolf in sheep's clothing.

No regen as of yet, I'll be ordering an ebrake soon. If I win a prize, I'm gonna get a satiator so I can make this battery last a little while. I added a picture of our ducks because they're cute.

All-road/trail commuter: Surly Krampus GMAC build

2024-04-20 | 555 views

My daily 15 mile commute consists of asphalt, gravel, mud, pot holes, a toll bridge(free for bikes!) and a couple of steep climbs, sometimes with very high winds and rain. Along with occasional side tracks exploring old forest roads and trails. I wanted to put together my first Ebike to do everything well and to be a fast and fun daily ride. As well as taking away any excuses I may to drive to work. I started with a bike that was already very enjoyable to ride and added excellent drivetrain components. The GMAC 10T, Phaserunner, Cycle Analyst, ERider torque sensing bottom bracket, Tripwire and lighting came from Grin. Along with comfortable hand bars, grips, big cushy tires, some left over batteries from cheap e-bikes of past and a “custom” crankset, cassette and derailleur setup it’s now a joy to ride. It’s taken a lot of tinkering, experimenting, research, zip ties, lots of questions for a knowledgeable friend and great help from Grin’s excellent customers service team to get my first DIY ebike project built. I am very satisfied with the outcome. The bike is happy at 3-30 mile per hour and will get 40 miles of range if I keep my pace reasonable.

2024-04-19 | 707 views

The Electrom project has been evolving since 2012. The bike is designed as a ground-up rethink of how human and electric power integrates into a safe and road-worthy vehicle that meets the legal definition of an e-bike here in Canada. The key features of the Electrom are: - Partial enclosure for weather protection and aerodynamics - GCD- Generator Chain Drive, which allows the rider to pedal as hard or as gently as they wish while contributing power to the system - Dual hub motors, Direct Drive, and freewheeling geared motor. The geared hub motor helps get the bike up to speed and to climb hills, but shuts down at higher speeds to save power. -100 liters of cargo storage, lights turn signals and horn, and the ability to carry a small passenger. -the system uses the Grin Solar shunt to measure the power generated by the rider via the separate on-board pedal generator and display the output values on the Cycle Analyst V3

I’ve also used it to replace solo car trips in the 5-10 mi range that would be a bit much for a regular bike. This was my first ebike conversion (and first ebike in general) and was pushing the limit of my technical knowledge/skills but despite a moment or two of wondering what I got myself into I think it turned out well. I was on the fence about getting a GMAC or a cheaper option but I have to say I love the regen! Anything to lessen potential bike maintenance, and I’m consistently getting ~10% regen with only minor hills which is more than I would have expected.

Stealth commuter with torque sensor

2024-04-15 | 535 views

A drop bar bike with minimal wiring and controls. This is my third Grin e-bike build. My AWD cargo e-bike, and high powered 72v bike offered me little fitness, and were very obviously powerful e-bikes. For my third build I wanted a bike that offered more fitness that wasn't obviously an e-bike. By not having a throttle, and relying only on a torque sensing PAS it requires me to put in effort when e-biking, while still giving me extra power to help with the steep hills on my commute. With a digital AUX attached to the seat bag, it keeps the handlebars clear while allowing me to be able to control how much assist I get. I set this up to go from 0% to 150% x the watts (effort) I put in. This allows me to determine how much fitness I wasn't on any given ride. With no assist the bike rides like a normal, just heavier. The only downside is that the clutch is not welded, so there is no regen on this build. Regen is the best, as it saves you time and money on brake militance.

The 18650 reCycled Old Mountain Goat

2024-04-09 | 423 views

Recycled dual suspension bike, recycled batteries, recycled BBS02, recycled Cycle Analyst, 10 year old Grinfineron controller and a recycled Old Goat. This time 8p16s cell arrangement, (batteries individually tested), charged to 64 V. (4 V/cell max). Same air cooled, individually fused, clipped in ( not welded) 18650 construction that make for a easily accessible, intrinsically safe shock cord mounted pack. Thermal runaway naturally subdued. This massive power flows through a 20 A Grinfineon motor controller wired directly to a Bafang BBS02 mid drive refitted with a ( recycled) 20 tooth front chainring. (Speed achieved with 48 tooth.) This torque monster abuses a 7 speed cassette to finally drive 26" recycled trick bike tires. Gold trim. Light, efficient, fast, yet agile uphill. Goat approved.

Fixed up and converted this old (late 60's/early70's) Schwinn Breeze for my wife back in 2000 as a Covid lockdown project. We found the bike in a scrap pile, but the original seat and green grips were in good shape! It's a 36V G311 geared front hub with cycle analyst bought as a kit from Grin. Front wheel relaced with HD spokes and rear rack added with 'California Prunes' crate for housing/hiding the controller and battery. It has cadence sensor with adjustable assist plus a thumb throttle. I initially built a small 10 cell battery and have just ordered a larger battery from Grin to replace it with for extended range. She loves the bike and I'm planning a similar build for my old Raleigh Sports so I can keep up with her! The kit was a snap to put together, the online tools were really helpful for spec-ing out all the components, and this was a really fun project that gets a lot of attention everywhere she goes. Most people are stunned to find out it's electric. Old bikes make great e-bikes!

$20 Thrift Store Mountain Bike Conversion

2024-04-02 | 464 views

After drooling over Grin's e-bike components and reading up on hub motors I wanted to try a test conversion on an inexpensive bike. Soon my wife bought me this $20 mountain bike at our local thrift store (Knick Knack Nook.) We have very steep hills here on Bowen Island, and our own driveway is especially bad, so I went with a large RH212 motor kit. I thought I'd test it out on this cheapo then get a proper bike, but as soon as I got it working I had so much fun riding it I couldn't stop. Actually I literally couldn't stop and had a crash and broke my wrist when a car turned into my path right at the bottom of a very steep hill. The pinch brakes are just not up to the task of emergency braking with a heavy motor, battery and 200lb rider. I had been so enamoured with the regen braking that I didn't even test how effective the pinch brakes were and rode for months before needing to use them. Lesson learned. Next conversion will be to a bike with proper disk brakes!

Last year, I built 2 light electric vehicules in France, basing my design on an open-source french concept : the Vhélio (vhelio.org). In one month, I built two of them from scratch. The first item was bought on June 5th and the date of departure was set for July 17th. on July 16th, the bike rolled out of the workshop for their first 17km. The morning of the next day, we did 90 km, and went on for the following 2880 km. 8 of my friends joined the trip, taking over each other. We left from Paris, aiming the Basque Country near the Spanish border (my grand-parents place). We had a solar powered trailer containing all of our tent and stuff. My first trikes, my first bike trip, my first real adventure, with my friends ! What an amazing experience. And I'm doing it again with new vehicules this summer. I had a Cycle Analyst V3 installed on board. Great piece of equipment !

## Concepts in mind maintain original appearance/be minimal, made for active pedalling, keep under max speed the bike was originally intended for. Most of the challenges were related to the bike's age. ## Lessons learned - the 22ah battery is heavy - when only going around town - use a smaller battery - buy a second battery - make my own - Old bikes have likely been crashed - Check/adjust spoke tension - adjust wheel alignment - fork alignment - any other alignments you can think of, it likely needs - Old bikes are ... old - new tyres and tubes - grease crank and head bearings ## Next project Figure out if I can find a cylindrical power supply based on the 4680 Cell. I'd like to make it look like a water bottle to blend in aesthetically with a pair of 1967 Schwinn Typhoons I'm restoring.

A one piece aluminium bicycle and sidecar. Front and rear clutcheless geared hub motor Ezee 26 in the front and GMAC in the rear each with a 25amp controller. I built the 57Ah 48v battery with Vruzend caps. The rig weights about 73kg, I weight 74kg and I can transport up to 68kg with ease. I live on Cortes island on the Pacific coast. There are very few flat stretches of road and a lot of short 200/400 m very steep hills with 8 to 14% grade, my range on the island is 60km. My average speed is 22km/h and I do not know my maximum, I am 72 and I take my adrenaline differently. In the past 3 years I have ridden 3832 km in all weathers except snow. The rig does not ride like a bicycle it is a sidecar and has to be ridden like one. I chose this design because I live in a rural area with roads with irregular surfaces and the geometry of the bike gives me great stability in a small footprint with a heavy irregular load. Living on an island I have to take ferries and the size of the rig lets me get on as a bicycle. My foot print is that of a touring motorcycle with panniers, but so much more nimble. I fabricated the bike out of square aluminium tubing because I could use my woodworking tools to do the fabricating. Izabelle Perry did the welding if you have any questions email me at [email protected] I now have 4300km and I am always amazed how well it works

My Avanti 26inch mountain bike started out as the test bike to see if I would like dd hub motors, regen braking and what size battery I might need before I build my 24inch fat wheel duel suspension bike. Easy to say the Phaserunner and Frankenrunner are the heart of my bikes . I didn't realize how much I would like and depend on regen braking and how much I would like the smooth quite speed. My bike's main use is as a farm Bike. I use it to chase sheep ,shift machinery and as general run around bike ,tool carrier. I have a homemade 20s 4p 72v battery with 21700 liitakala cells and an active bms. The bms has no low high or amp restriction , it just balances the cells . All the controls are left to the phaserunner / frankenrunner including the power reduction ramp down as the battery runs down so I can always make it home . The main frame off the new bike is bent and made from an old road floodway sign. The back suspension bit of a mock up and many get changed , no quite sure what to do there.

The goal was to build a bike for my son which could be use as a commuter bike to school and on the local trails in Squamish utilizing primarily components from BC companies. The frame, rims, front hub, handle bar, stem, seat, pedals are from Chromag in Whistler. All e-components are from Grin Technologies using the Rear All-Axle hub combined with a 52V battery, Cycle Analyst and the Regen brake kit. Carbon Raceface cranks bring a third BC company into the mix. The slow wind was selected for the Rear All-Axle hub motor to ensure excellent uphill performance in Squamish. Regen works amazingly well using just the lightest brake lever movement to control the amount of braking. Seamless transition to full stopping power with Shimano Saint brakes. Shimano 1x11 XT drive train. Modified MKS Mud guards to allow for year round riding. The bike came in at 55 lbs. The performance matches very well the simulator.

Solar touring tandem with a custom regen-capable mid-drive trailer to tour rugged roads and mountains! Good experiences with our last solar touring tandem, going 10'000km to Cape North and around Switzerland led to this second design. We had some clear goals set for our current tour of the Americas: - single-track to be more bad-road capable - gear-change on motor a must, we get up to 22% with 250kg system weight - regen as a nice to have - first and foremost to have an additional brake on the trailer Who could deliver a better system for such a setup than GrinTech? So far we have around 4500km of touring and 1000km of testing under our tires, in all kind of conditions. Icy Swiss winter roads, bad mud tracks and good cycling in France, hot and dry climate as well as heavy rainfalls in Mexico and Belize... to be continued! In France we grilled one Baserunner probably due to too-high regen RPM - immediate support from Grin, a bigger pinion and enabling moderate overdrive got us quickly going with support again. Apart from this, our very experimental setup runs like a charm and flattens hills like no other!

New E-Life for Rental Tandem

2023-09-16 | 700 views

I bought a used Fiori tandem off a rental place for cheap, stripped it to the frame and rebuilt it into an e-tandem with an RH212 motor. E-tandems are great for harnessing regen power as there's the weight of two people but the wind resistance of one, while the RH212 is a big, torquey motor that allows for a lot of regen power. With these, I made a proportional regen system that operates right of the back brake lever.

The tank. I've made the first frame with low positioned battery out of an old donated bike named Taifun with front Chinese spring fork, bat. 36VNom@2232Wh, 25Amp Chinese controller and 6kg heavy motor. Didn't have much of an idea what to do with it at first so I rode town mostly. Randomly ended up in the mountains and liked it a lot but my wrist were not having it at all due to vibrations. So I've started creating completely new frame in 3D with a proper fork and battery located at the front dimensions mostly derived/updated from V1.0 :) . Using phaserunner with CA3 I can get up-hill torque support at a certain level to keep the speed around 10-15 km/h and kickscoot at the same time ending up with great workout and a lot of trail and DH fun rides, thumb throttle rides also possible. Thanks to Grin for this amazing product. Right now I'm working on the new frame for next season, completely closed up sheet structure, scooter will be about 8kg lighter in total hoping for 25kg and about 48VNom- 1500Wh battery pack. Current frame is 4 CrMo tubes 18x1mm and 14x1 mm mig-welded with some reinforcements at the lower structure due to excessive flex cracks. Front fork is Fox Talas 120-140-160mm depending on the trail conditions lower is better for workout but not much for trails. The battery is modified standard (6s2p) VDA format now 12S @ prismatic 62Ah a cell 2732Wh this will get me 3 hrs in the mountains plain throttle, ride distance around 70km (200+km of flat surface rides) all distance values depend on, we all know what.

A stealthy wheelchair pusher unit that uses a geared hub motor mounted with battlebot omniwheels. Using a fast wind Bafang G01 and a 48v battery top speed is a bit over 20kph. A Cycle Analyst keeps the power controllable allowing the user to creep across the room holding a cup of coffee as well as keeping pace with others on bicycles. A thumb throttle is mounted on the wheelchair frame next to a disc brake lever (Individual disc braking provides steering by 'drag' braking). The unit has pushed me over 5,000 miles so far.

2WD Cargo bike

2023-08-29 | 598 views

Home built Long John Cargo frame made from a gutted 90's Trek Yukon MTB. Grin All axle hub on 20" rim in front, Ezee std on 26" wheel in the rear. Each powered by L10 Baserunner. 16 x Ligo batteries integrated into the undercarriage. Torque sensing BB, I ride the bike around daily at 1200 watts (~600 watts each) but have had it up to 3200 watts for short stints just to test it up a hill while fully loaded. The bike went up the hill like it wasn't there! Hoping to put some solar cells onto the top of the cargo box for slow charging while parked. Goes anywhere hauls anything!!

Front hub 750d Gravel Bike

2023-08-28 | 654 views

In 2016 I built up my first front hub 700c drop bar bike using 9c/controller/CA3 Grin components with a 48v 12ah Dolphin style battery to be able to ride the rough roads in my area. It was when they were teasing the All Axle but not quite out with it and as soon as I could get one I built up another bike with that motor. I got many miles out of each riding all over NW Oregon and other parts of the west from sea level to 10k in CO.. The bike I am presenting is my third build on the same principal of a front hub non PAS bike. Although I like torque sensing PAS on my eMTB for use on primarily road surfaces at a consistent higher cadence I prefer to utilize the cruise control available through the CA3 and use a Schlumpf High Speed Drive crankset that has up to a 160" gear for pedaling along at whatever cadence and input effort I desire or the terrain calls for. It is a much more natural experience I find. The bike has what are little known as 750d wheels which are in development by WTB. Because they are larger in diameter than conventional 700c wheels like my other bikes had it required a new frame/fork which was supplied to me back in 2019 and is made of steel. Covid got in the way of their release but there is some amount of press going on currently about them so you may see more of them in the future. Biggest benefit over 700c I have found is that they roll very well when up and on step but are a little slower to get there. The available power and consistent momentum you get from the hub motor helps in that regard. I also have a conventional wheel built that I can swap in and leave the battery home when I want to go acoustic. To me one of the beauties of a front wheel drive, as well as the two wheel drive aspect that can come into play on certain terrain. I really like the All Axle's ability to adapt as a 12mm for this bike as there is only one fork available and that is the standard for it. I also really like the built in torque arm and came up with a way so that a 5mm allen key is all that is needed for removal of the wheel. I use a STD version and it is sufficient to move the bike along at illegal speeds if wanted in addition to the ability to pedal effectively at those speeds. But for the most part I just power along using using up to 500w and go for distance over speed to get there. What I really wanted out of this build was to shield the controller and battery from plain view and thus I have an L5 baserunner and a shrink wrap 52v 21700 cell 17.5ah battery residing in the top tube bag. Leaves room for a couple of King Cages and I would say mission accomplished. I also made a 1 1/8 flat mount for the CA3 that nestles it nicely away below and behind the bar yet easy access for vision and button pressing. A Shimano 10spd, doubled via the Schlumph to a 20spd, with brifters and hydraulic brakes are sufficient I find for a drivetrain and stopping power but the first thing I go for when slowing down is the red button that activates the regen as well as shuts down the cruise control.

“CCC” Compact Cargo Cruiser – E-bike and more

2023-08-28 | 569 views

Is there an “everything” e-bike design that can give a second car a run for the money? I think so and this is my attempt with the following design parameters: maximum total power under 750 watts, both front and rear wheels have seperate throttle power, cargo capable with the ability to comfortably ride two adults, no longer than a larger regualar bike, three season capable with rain/sun protection and enough lithium battery for a 50 mile range. The bike will have scooter/moped characteristics but still be recognized as a bike and allowed down the bike path. At other times the bike must hold its own on the city streets with the slower traffic. I have included a detailedd build section with this posting showing some of the details you might find interesting or informative. I hope some of my design ideas inspire more bikes like this for all around use.

Torker E-Bike with all Internal Gear Powertrain

2023-08-27 | 537 views

I prefer internal gear solutions. There are some good ones out there. For this Torker E-Bike frame I used a SRAM 3-speed IGH and a Patterson 2-speed crankset. The 2x3 gearing solution worked well for my needs and I never got grease on my work pants. This bike started out with the classic Outrider front hub motor from which l later upgraded to the Bafang G01 motor.

A friend lost the strength to squeeze any object with either hand. So using traditional hand brake levers and throttles would not be possible. So we created an E-bike from frame using Grin parts to make it work. Solution: Us a direct drive motor on the front wheel for electronic braking activated by a palm press on the brake button. A kickback braking rear hub was the brakes for the rear. I installed an NCTE bottom bracket for throttle and PAS control. I worked well for her.

Specialized Ariel G311 Conversion

2023-08-27 | 555 views

We bought this Specialized Ariel from Greggs Greenlake Cycle in Seattle, for my wife, but she never really put many miles on it. Seattle is a hilly place and ascending these hills was difficult for her, even with the 3x9 drivetrain. So after we moved back to Canada, I put a Bafang 311 kit from Grin, complete with a Baserunner Z9, eRider torque sensing bottom bracket, and of course a Cycle Analyst. I built a 52V 600Wh battery for this bike, with the Baserunner installed in the battery tray. I chose this kit due to it's low noise and weight, as well as to keep the stock look as much as possible. This has ended up being a great choice, since my wife does want to put in work, but might want a bit of help on the hills. The G311 does warm up pretty quick, but during casual rides and commuting it provides adequate help on hills. She doesn't use a lot of assist, and averages around 5-6 Wh/km giving the bike a range of over 100km, which is more than she will ever ride in a day on this bike. This has ended up being a great bike for commuting and casual riding, without becoming too "motorcycle-ish", and she's been enjoying it a lot more now.

Modified RadRunner

2023-08-27 | 572 views

I bought a basic RadRunner off of Kijiji and have since modified it to be much more capable. I used the Grin video on YouTube as inspiration, and am very satisfied with how moddable the RadRunner is, and how well the Grin components have worked. I have the Rad large front basket, bag, fender kit, passenger kit, and the Superknuckle monkey bars so that I can haul groceries and my kid around easily. This bike, plus the Grin mods have really changed how I get around the city. I avoid using my car as much as possible, and this has made this so much easier. To support the extra weight and to make the riding experience much nicer, I've done a lot of performance upgrades as well, including a custom 850 watt hour 52V battery with the negative grounded to the frame using a 100mA fuse, V6 Phaserunner, Cycle Analyst, ERider T17, Thumb Throttle, Shimano MT201 Hydraulic brakes, Diety Pedals, Raceface grips, as well as a 12V DCDC converter which currently just runs the upgraded brake light, but I may soon use it to provide power to the ERider bottom bracket so I can upgrade to a 72V system. With some field weakening I am able to hit about 45 kph, which is plenty fast for this type of bike, and I typically don't go that fast anyway, so maybe I won't bother upgrading to 72V. I had originally used a Baserunner L10 to power the bike, but at a stop or at low speeds it would shudder when trying to get moving, which is a bit of a problem given the aggressive single speed gearing, and the all the heavy accessories + kid on the bike. I had used the Baserunner on a GMac earlier with no problems, but there's something about this heavy bike and Bafang G60 that didn't play nice. Playing around with the Phaserunner this problem disappeared when supplying 90 phase amps, so I stuck with that solution, and am super happy with the outcome. The motor is a stock G60 motor and I am using the Z916 to L1019 adapter cable, so there is no temperature monitoring. I'm running 30A max from the battery, and am always conscious of the power I'm applying versus speed so that I don't roast the windings. I mostly need the 90 phase amps just to get going from a stop, especially on hills, so try not to push it too hard between 5 and 20 kph. I am hoping over the winter I can complete an L1019 cable swap + add a thermistor so I can run even more power and not have to worry too much about frying the motor. I had some issues with the ERider initially, but I was able to find out that grounding the battery to the bike (with a small fuse) solved those problems. Everything works great now.

My Fat Trek, created for comfort

The result is a lowered balloon tire comfy bike with great balance and power using the Ezee rear motor and controller.

Freecross upgraded to E-Freecross fast bike

2023-08-26 | 573 views

Since the Freecross comes with a 16 speed rear IGH, the only other power solution is dual front side axle motors. With dual baserunner controllers, a PAS bottom bracket, CA3 and large downtube battery, this bike can go fast! Additionally, dual front headlights and rear lights from Grin with a raised instrument cluster give it ergonomic function. There is also a front/rear camera system installed to record rides.

Micky's Bike

2023-08-26 | 641 views

The goal when building Micky's Bike was to create a clean, capable, and unique ebike. To achieve this, I used a 2019 Specialized Rockhopper as the base with an RH212, Baserunner L10, and a homemade battery pack in a headless, dual-throttle configuration. A few details about the build: The battery pack was built using Lishen 21700 cells in a 10S 6P configuration to produce a 36V 24Ah battery. The custom battery allowed me to design and build my own mounting system using wood for a dark-stained finish. By using wood, I was able to chisel out a void in my vertical support to fit the L10 controller in a recessed and secured location while still providing exposure for heat dissipation. By mounting it at a diagonal I was able to help maintain discrete cable routing where possible. I chose a dual throttle configuration as I wanted proportional control of both my acceleration and regenerative braking. To maintain a clean look I was able to utilize a free channel in the bike frame to internally route a multiconductor cable to wire both throttles through the frame and back to the controller. Additionally, I routed cables through the seatpost itself to wire in a hidden on/off switch under the seat for convenience and increased security. I ride this bike daily for my commute from Fairview to the Northshore and back and love every second of the ride! It's also a ton of fun on the trails.

2023-08-24 | 537 views

The Cyclete is one of the best stand up bikes and with the addition of the Grin All Axle hub motor, a great E-bike. The challenge with this style of bike is the limited options for the downtube battery placement, always on the front with the total weight of battery and motor to be unbalanced. So with a Topeak rear rack and a special 3D printed front bracket for it, the downtube battery is now in the rear as a good counter balance to the front motor. I really enjoyed working with the Grin All Axle motor for this install.

Salvaged BionX Hub motor. Commuter e-bike

Over 16000 km since April 2020, so far so good )) I use it for my daily commuting, all 4 seasons, good weather, bad weather, sometimes for bike touring. It is fun to ride and i love all the features I've got using GrinTech products: regen e-brake, back pedaling braking, electronic freewheel, pedal assist, throttle, the control and monitoring of all parameters. With the MF Switch i control the PAS level. All the parts where purchased at ebikes.ca: *Cycle Analyst V3_WP *Multi Function Switch *Throttle *Baserunner L10 *36V 19Ah 21700 Downtube Battery *Tripple Bob *L1019_M cable for the motor *Cycle Satiator Charger * Thermistor 10K *PAS_12P *Sate-lite 1.5 Watt Ebike Light *Sapim spokes This conversion was inspired by the YouTube video posted by Justin: How to Salvage / Hack a BionX Hub Motor for External Controller and 3rd Party Batteries https://www.youtube.com/watch?v=Wc8OJtFRUng&ab_channel=GrinTechnologies I have followed all the steps shown in the video and successfully salvaged this BionX motor. Here are some advice from my experience: *If you don't have the gear puller and you live in Canada you can loan it for free at "Canadian Tire" thru Loan A Tool Program. This one you can see in the images is a 7 ton gear puller. * To remove the torque washer from the axis i made a DIY bracket from a L-shaped steel angle since the gear puller jaws were too thick to grab the washer * Don't forget to insert the cable thru the lid and the bearing before soldering the wires as Justin did ))) * The Speed sensor wire in the L1019_M cable can be connected to one of the outputs of the hall sensors. I made a mistake assuming the speed will come from baserunner since the 3 hall sensor were connected but it turned out i have no speed indication after i assembled the motor so i did a small cut in the cable and connected the wire to a hall sensor wire because i didn't want to disassemble it again. * Check the bearings maybe they need to be replaced too since the motor is already disassembled. Mine were marked 6003 LB wich is a 17X35X10MM sealed ball bearing. I've replaced them now after 16K kM, who knows what mileage they had before. As for the performance you can get from BionX PL350 motor - i have compared my real data, speed, consumption with the Motor Simulator and Trip Simulator available in TOOLS section on this site and they are pretty accurate. The motor is not very powerful but good enough for a comfortable ride. I can give bursts of 700 - 1000W without problems as long as i monitor the temperature on CA. For long term power - up to 350W is ok, higher it tends to overheat above 90 deg C especially during summer heat. It is not very effective for steep uphills. The average consumption is about 8.7W/km if i set the power level at 200W-275W and 11-13W/km at 350W (700x35C tire) With my 36V battery i can reach 35-42 Km/h. Usually i ride it at 25-30km/h with 250W PAS level. Good luck with your projects! Special thanks to Grin Technologies for all the shared knowledge and good quality products!

Edgerunner Long-tail Cargo

2023-08-19 | 575 views

The Xtracycle Edgerunner is long-tail cargo bike it has a 20" rear-wheel to keep the load deck low. In 2015 I converted it to electric with a kit from Grin called the "Cycle Stoker" the kit included a pretty awesome mounting system for a direct-drive hub motor to be mounted behind the seat-tube and underneath the cargo-deck. The chain wrapped around the hub motor into an 'S' shape with the use of an idler pulley. The mount had a strain-gauge ingeniously included so it was an after-market torque-sensing mid-drive system! The kit served me well for 6 years, but I kept wearing through idler pulley's and had to replace the freewheel sprocket on the hub motor a few times (until I ponied up for a White Industries one that was seemingly indestructible). In 2022, I decided to convert the bike again and this time chose a GMAC 10T motor built into the rear 20" wheel, a Frankenrunner controller, and even a new battery with more capacity (the old kit is being repurposed for a few projects, including a commuter for my son). I absolutely LOVE the GMAC motor and new controller! It has gobs of power and can actually climb better than the old mid-drive set-up. I also really like the regen system, especially in my steep hilly city. I did have a minor issue at first with the torque readings going wild when the motor kicked in, which was solved by adding a grounding wire from the power circuit directly to my bike frame. My life-time average with the mid-drive kit was about 14Wh/km, and the new kit is almost down to 10Wh/km, which along with the bigger battery has greatly increased my range.

Last year I picked up a used Cruzbike Q559 to add to my bike collection. This spring I added a Bfang G311 front wheel 500 watt motor to the rear wheel. I had to do a tiny bit of modifying to get the brake rotor to fit. But with around 500 miles, everything works great. I have a Cycle Analyst 3 controller to allow a maximum of 200 watts (I like to get across busy intersections fast) to the Grin throttle, and a maximum of 125 watts when using the Grin 24 pole PAS system. My sweet spot for riding with this set up is about 21 mph, or 33 kph. I run a 12 amp hour battery (which sits in a custom made battery bag above the rear wheel), which I charge to 85% of full using my Grin Cycle Sator charger. This bike is my go to neighborhood errand bike. This is a very quiet running e-bike.

Bacchetta Giro e-bike

2023-08-10 | 544 views

The idea came to be my first e-bike build in 2021. After seeing what Bacchetta wanted for a factory Giro made me wonder if I could build one myself for less money. Enter Grin Technologies and my idea was realized with the purchase of an eZee Front Wheel Ready to Roll Kit. The kit included one 20 inch rim laced to an eZee L-10 motor, down tube battery, Baserunner controller, V3 Cycle Analyst, pedal sensor, torque arm and auxiliary input and power switch. There where a few extra accessories but that’s the main parts. The power is used for pedal assist only, no throttle. Highest mileage on a single charge has been 128 miles. The battery box is made of thin plywood and attached to the main tube by a pair of T-Cycle pannier brackets.

2nd Hand Yuba Boda eCargo Bike with BionX System- RESTORATION/REPAIR PROJECT

2023-08-07 | 417 views

I want to keep the regen on pedal stroke capability of this eCargo Bike I just traded carpentry work for however the battery is not charging & the company is no longer in existence... with the help of Grin off the shelf products & maybe their expert input I hope to restore my eCargo Bike to use as an everyday to & from work on my carpentry/contracting projects. Even as just a Cargo Bike I have already picked up 4' sheets of material which would have been impossible to transport with my Mtb so even as just a bike I like the unit. Still I need to learn & restore this regen system. It needs a 48V BionX Battery or rebuild & probably a battery management system board. ... More details and rework / repair pictures to be added as this project moves along.

Xtracycle free-radical conversion with 1st-generationStokemonkey STILL in service since 2013.

2023-08-07 | 462 views

Bike started as a 1999 Specialized HardRock mountain bike that was my commuter bike for many years.. First step was using an Xtracycle free radical conversion kit to turn it into a long-tail cargo bike in 2011. Replaced the front rockshox suspension fork with a rigid Surly fork. Mountain bike handlebars were replaced with swept-back bars from Velo-Orange. Next was a Rolling jackass cargo bike kickstand that allows for full loading to either side with no worries of falling over. Final touches were a used stokemonkey conversion kit from 2010 that I purchased late 2013 along with a USED 36V 15 ah LifeP04 battery that turned this Frankenbike into a high-torque, mountain-climbing goat. Last few items were adding a front rack from CETMA and Wald front basket. Car horn is from LoudBicycle. Charger is a cycle satiator which I bought the first year they came out. Bike is still on the road today with that 13 year old battery. I attribute its incredible longevity in large part due to the cycle satiator. Thanks Justin and Grin! Ty

Bullitt

2023-08-06 | 563 views

Here is our everyday life Bullitt with an RH212 engine, CA, Phaserunner and touque sensing BB. The battery is 17,5 Ah big with 48V. I ran it normally with up to 25 or 30A to have enough power in a hilly city and daily load of shopping and one kid (around 170-210kg total load). The regen breaking safes a lot of brake pads and brings between 7 and 17% of energy back. In the future I would like to upgrade to two 17,5Ah 48V batteries under the front deck and an Grin All Axle front hub engine for better efficiency on hills and to get rid of the moving and getting lose trailer attachment. This happens because of the power and regen changes and would disappear with an integrated torque arm from Grin.

SX2 on a Schwinn Voyageur Sport

2023-08-06 | 436 views

Put an SX2 on my 20 year old Schwinn. I bought the bike when I was first out of college and commuted to work on it. I always liked the upright riding position for a tall rider and that it could take any street and some moderate groomed rail trail use. I met my wife while riding this bike, so it has some sentimental value as well. We've since moved to a hillier area in NJ, and any ride from my house requires a big climb back up, which tended to limit my riding. I've already had it out for some fun weekend rides around the area and grocery trips, and hoping to do more as I get a feel for it.

The bike was fabricated by my brother Paul from parts collected at the curb on garbage day circa 1974. Two CCM Mustang frames were used to create the stretched rear end. A lenghtened1950's Monark fork and a 3-speed Sturmey Archer hub with drum brake add exoticism. It became an ebike in 2002 because my first hub motor only had 28 spoke holes which did not work well at all when fitted to my mountain bike. I recently revived the e-chopper because it is a blast to drive. I use the 48v 15ah LiIon battery from my regular commuter.

Commuting ebike for me and my daughter

2023-08-04 | 457 views

Hi, 15 years ago y had a Little Scooter (50cc 2stroke motor), The Bogota City Municipality prohibited the 2 stroke engines in the city, I already commuted a lot by bike so I decided to build my own ebike instead buying a new petrol scooter. At that time, I was a pioneer in Colombia with the ebike mobility and during the R&D process to build my own ebike I found Justin and ebikes.ca, from which I learned most of what I know. They have been providing me unbelievable products and support since 2008. This is my last build, adapted with versatility in mind, I have a 10 year old daughter and she loves to ride seated on the extra seat, sometimes she drives and I pedal! It´s so fun. I love my ebike I can´t imagine living in this jammed city by car…

Electric Yuba Mundo

2023-08-01 | 530 views

I wanted something to carry my wife and I plus any cargo for around-town trips like visits to the farmer's market, or even just getting coffee on the weekends. This bike more than delivers for that. The bike is a Yuba Mundo v4. It uses a GMAC motor, phaserunner v6, CA-3, and torque sensor. Connected to a 52v nominal battery, housed in the triangle bag. This bike is not intended to be fast, but rather to handle any kind of load we could conceivably throw at it. In fact, in the cycle-analyst, I have the pedal assist limited to 15 MPH (24 kph). Which is more than fast enough for the kind of load on the bike, the quality of the roads around us, and my general comfort on the bike. I absolutely adore the GMAC. Having regen is absolutely amazing for this bike. Having the torque sensor and getting pedal assist proportional to the amount of work I do has been great for preserving the "bike" feel.

I wanted to build a speedy, every day trike for my daily commute, my shopping, my family and friends visits. In short, this is the reason for not using my car, as much as possible and still have lots of fun while riding it. I transformed my good speedy muscular recumbent trike into a 70ish km/h fast vehicle (max speed tested in the countryside). It's pushed by a rear 9C RH212 (Fast 10.6 RPM/V version) with statorade fluid inside. The biggest front chainring is 56 and the back, a classic 11-32 cassette. It has a homemade battery nominal 61V 20AH (17S4P Samsung 50E - approx 1200 WH of capacity) and approx. 40A max. I love the natural feeling of the pedal torque sensor and the regen that can push back up to 20% of energy while riding in town.

SB Cruiser 2WD Heavy-Cargo Trike & Dog Carrier

2023-07-31 | 945 views

This one has evolved since about 2015, with the original need to carry Tiny, one of my St Bernards at the time, as well as groceries, cargo, and the copious amounts of dog food required. Tiny, and later Kirin, both loved to ride in it, so there is an avatar of Tiny on the trike, and both their collars are there. The trike has outlived all the dogs except JellyBeanThePerfectlyNormalSchmoo https://twitter.com/PerfNormSchmoo who does not ride in it anymore, but it is still my only transportation, and a mobility aid in that without the motors I wouldn't be going anywhere (too many parts of me worn out), and still regularly carries 200-300lb grocery loads, and similar dog food loads less often. It can also pull a custom-built trailer, and has hauled several hundred pounds of dog food multiple times, and a piano once, and many other varied large and/or heavy loads twice it has carried a queensized 12" thick foam mattress on top. I don't know what it's maximum load is I haven't broken it carrying things yet. -) but I try to keep it to 300lbs directly on the trike, and use the trailer for heavier things. It was built of assorted reycled materials to be adaptable to each of those as the need arose, though it has since been narrowed down a bit, to create a slightly bigger and more secure (and cooler in the desert summer heat) cargo space that is permanenly installed, which also includes significant lighting for better safety in city traffic. Braking is primarily handled by a single Avid BB7 MTN 200mm on the front 26" wheel goes thru pads sort of quickly but has so much braking power I can easily skid the wheel before reaching even my wimpy max lever pull. (a rebuild of the back end to install rear brakes of the same kind has been on hold for at least 3 years now). It handles far better than you would expect an upright delta trike to do, because almost all the weight is down low and centralized. It is rather heavy with me on it and typical everyday cargo it is probably between 400-500lbs I'm not quite half of the lower estimate. ELECTRICS: The basic drive system is two (presently mismatched) hubmotors, an MXUS 450x and an ex-stromer Ultramotor (sans internal controller), each in a 20" rim with 2.25x16 moped tires. Originally used a pair of older Grinfineons but today just the MXUS is driven by one of those, and the UM is driven by a generic similar in power but lacking in the functions. All are powered by the same 14s 40Ah battery of EIG NMC cells, with a Meanwell HLG-600H-54A as an onboard charger. Both are controlled via throttle from Cycle Analyst 3.1x, which is setup to read the cadence sensor of a TDCM BB (not using torque sensor at present), and output a throttle signal to both controllers, as the system is normally pedal-controlled. It is speed limited to 20MPH to comply with AZ legal restrictions. There is a metal ATV thumb throttle operating a cable-operated hall throttle box to use for a "get started" button for conditions where I cannot push hard enough on the pedals to move them and get going normally, and for increasingly-less-rare times when I am physically unable to pedal. Side note: because the Grinfineons respond to proportional regen on the throttle input, and the CA is designed to send that when the ebrake signal is engaged, but the CA has no second input for controlling that braking level and instead uses the throttle to do so, I added a second COT pulled by the left brake lever, and relays engaged by that lever's ebrake switch that swap the CA's throttle input to that COT instead of the thumb-controlled one (and also turn on the CA ebrake signal and turn on my brake lights), so the brake lever modulates the braking level. Since the braking throttle input range is not separately controllable in the CA, the modulation isn't ideal, but it works. The generic controller presently used on the right doesn't respond to that, nor have a useful regen function, so it instead uses the antitheft function that actively opposes wheel rotation, tied to an emergency-only ebrake switch--it's very hard braking, but is very hard on the motor and the controller. LIGHTING: Powered by a separate 4s 40Ah pack of the same cells as the traction pack, charged by a Grin Satiator set to 16.4v with a custom profile. DOT headlight (salvaged from a piece of a KIA left behind in a parking lot after (presumably) a collision), DOT trailer taillights, turn signals, and brake lights. LED light strips for accents / downlighting, and additional turn signals and markers. Front and rear are also sequential-turn-signal LED lights that have steady marker lights when not signalling. All daylight visible at least as much so as the average car/truck/etc. I'll add sections with more specific data on various parts, trips, etc., once I have time to do so. Until then, please see the build threads in the Links section. )

Commute Crusher

2023-07-31 | 478 views

I have a nice multi-use trail that I can take to work, but there's very often strong winds that make for a miserable commute after a long day of work. Enter the commute crusher. While sitting upright, wearing jeans, and carrying a heavy pannier, I can now easily fly by hard working spandex-clad road cyclists. The bike started as a stock commuter bike. I changed the stem to make the riding position more upright and added the GRIN conversion kit with an amazon 48V battery. I used the SX2 Rear Helical Geared Hub Motor, Standard Wind with a 700C wheel build and the Z9 baserunner. I had hoped to install the baserunner in my battery base, but the amazon battery base wasn't the right shape so it didn't fit. Not everything mounted perfectly, but I was able to make it work. Despite the fairly small motor size, this bike now crushes my commute. I can easily cruise over 22mph while wearing jeans and not working very hard. Top speed on flat ground with light pedaling is somewhere around 28mph. I don't think the motor (or my battery) could sustain the higher power levels I sometimes use for a long ride, but my commute is only ~6 miles each way so it's no problem. Next step is probably to upgrade the brakes, or at the very least replace the pads and make sure they're well adjusted.

My minimum range going as hard as it can handle (3500W peak front, 2500W peak rear) I can get 100km. Maximum range can be 300km+ depending on conditions/speed/weight/solar-output/pedal input. Front wheel have a slow wind All Axle Hub, for high torque, and regen enabled, generates 2kw on high speed fast decelerations. Rear has a 1000W MG62 Bafang hub motor, that pulls the bike to a top speed of 75Km/h. At full charge and good conditions, will pull 0-60km/h in under 5 seconds. All batteries where built by me, all packs have BMS designed to link in parallel, so 4 battery packs all link as one, and can output a total of 240A at 72v, limited by BMS, cells can output more. One triangle pack, a back-rack pack, and 2 side saddle packs. Trailer has 2 100w solar panels, and extra plastic to help enclose it, keeping my things clean and dry. I use the trailer for camping trips, but mostly for my e-bike repair service, where I put all my tools in it,(as seen in photo) and go help people with e-bike issues. I have 2 high voltage Satiators in the front rack, to give me 720W charging speed. as well as a 12V battery for the lights/horn/alarm and a charge for it. Built the racks and re-enforcing frame myself, so hold all the batteries and components in place, and make sure the frame can handle all the weight at high speed. Back-Rack is designed to sit on, with custom foot hold to carry a passenger. Custom made trailer hitch in the back, is stronger than OEM design, that did not allow hub motors to be installed with it. Log jumper guard on the bottom bracket to protect chainring and wires while jumping over fallen trees. 200mm hydraulic disc breaks and regen breaking combined with fat tires give great breaking performance. Have put 10,000km on the bike at this point, and 7 years of constantly breaking and upgrading till it evolved to the point it is now.

Kid Carrier / Grocery Getter / Suburban Do-It-All Commuter

2023-07-29 | 567 views

I took a Yuba Supermarché and electrified it with an RH212 (with Statorade), Phaserunner V6, E-Rider torque-sensing BB, and Cycle Analyst. Front light is from Grin, rear light is a hardwired Niterider (no mods required, accepts battery voltage), and seat is a Selle Anatomica that is perfect. I reused an EM3EV 850 Wh battery from my other bike that is still going strong in its 3rd year. I chose an RH212 over a GMAC because I wanted something quieter and with better heat-shedding capability. On these counts, the RH212 delivered. I don't think it has ever been over 50 C, even in the San Diego summer going up 12% hills, with 100+ lb cargo in the front. The drawbacks are a slight loss in efficiency and significantly less e-braking power (on a GMAC 10T, I've hit 1200 W regen, whereas this RH212 8T will only hit around 800 W I don't know if that something I should expect just based on winding speed). E-brake cut-off is handled by using unmodified Tektro levers, which saved me a lot of pain compared to modifying levers to accept a Tripwire. It's my daily driver for dropping off and picking up kiddo, getting groceries, getting a bite with my partner. I get a lot of positive feedback from people, especially motorcyclists. Only issue that remains is a bug where PAS will cut off and die suddenly under particular circumstances. Seems to have something to do with using throttle and pedaling forward at the same time (has happened both during accelerating and e-braking). I've grounded battery negative to the frame, but this didn't fix it. I will start to log Cycle Analyst and Phaserunner data, hopefully that will point the way. Planned future upgrade is a solar panel canopy / sun shade.

Solar Cargo Recumbent - Tilting Trike

2023-07-29 | 598 views

I built this trike for long-distance, heavily loaded solar-powered touring. The frame, bolted together out of aluminum square tubing, is an upgrade from my beloved FlevoTrike - it has the same tilting mechanism, Python lowracer steering, a longer wheelbase. The large cargo box is made from plywood and scrap plastic scavenged off a damaged vending machine. The e-assist is an All-Axle Hub Motor in the right rear wheel controlled by a Phaserunner, with a battery charged by a 150W solar panel on top. People often comment on the use of crutches to support the solar panel, but don't always realize that in addition to being cheap and effective, they're height-adjustable so I can aim the panel at the sun when parked. It's longest trip so far was to the Mexico-California border and back (~2000miles / 3000km) and it has almost certainly accrued another few thousand miles/km in shorter trips.

Initially I added two 100 W solar panels to our TerraTrike Tandem Pro, which has a hub motor and Cycle Analyst. Then just for fun, and for the bike ride across Iowa this week (RAGBRAI), I added a Flux Capacitor (Amazon USB night light) and a Mr. Fusion Home Energy Reactor (made on my 3D printer). It generated thousands of comments from other riders.

All Wheel Drive with BBSHD and Grin All Axle

Grin All Axle front motor with 20 mm axle, Phaserunner controller and a Cycle Analyst. The stock Bafang BBSHD is working on CA as well, the throttle signal goes to both controller. And another throttle to the left for variable regen up to 12A. 15S 6P battery with Samsung 30Q cells and around 3,000 watts of total power. Went to a open E-bike race on gravel with many bends, 1,400 hm and 14 km – finishing first in 16 minutes. Lots of fun and grip on this bike, in steep uphills, there is a bit of wheelspin. Both motors stay cool enough on full throttle, because they have less load. About 30 kg in total with 180 mm of travel.

Wooden recumbent bike

2023-07-28 | 644 views

The bike frame was originally made on my CNC router in 2012. It is a hollow frame (3/8 inch, or 9mm) that is made up of laminated walnut, hard maple, and purple hearth woods. The wood frame actually soaks up road vibration pretty good. The bike is built for speed and efficiency. The recently added Bafang G310 rear motor is connected to a cycle analyst 3 controller that limits the power to 125 watts. This gives around 1 amp hour of battery usage per 9 miles or 14.5 km. And with a 10 plus year old 12 amp hour lithium battery... there is over 100 miles (160 km) of range on this bike. The Zzipper fairing helps with aerodynamic efficiently, as well as the rear wheel disc.

The Build

2023-07-28 | 520 views

Full suspension mountain bike build. Found and older frame, stripped down, stripped paint and rebuilt and painted. Changed over to disc brakes all round and mounted Grin electrical components. My first build and not sure what I wanted and type of riding I would do. Went with basic throttle, Ca-DP analyst, 20 amp Grinfineon controller and Bafang G310 rear hub motor. Installed 36v 20 AH triangle battery. Very happy with build and power for type of riding I expected to do, around town, highway and fairly flat walking/biking trails. As time progressed found myself and others taking on slightly more hilly trails. Now find my legs and bike motor powering out on these trail hills about 3/4 way to top. May have to do another build with more powerful electronics. Will not advance riding past this level of hills doing now (my body is getting too old), but sure enjoying the rides.

For a couple of years now I've been trailering my gear twice a week to my hockey games. I play year-round, and my ebike makes it a breeze to haul heavy loads on the hills of the North Shore. I ditched the stock charger that came with the bike for a Satiator to take advantage of the battery-saving programmability it provides. In addition to hockey, I use the trailer for grocery shopping, Costco runs, and the odd craft brewery hub crawl.

Not your typical Razor E300

2023-07-28 | 504 views

Back when I was 7 years old, I got a Razor E200 for my birthday from Canadian Tire. After many years of collecting dust and the first COVID summer, I decided I would mod it. I chose a 250W motor from AliExpress and a friend of mine that was working for Rocky Mountain back then told me about Grin. He supplied me with a battery he had laying around. I pushed 1000W into that poor motor for a long time (it is still running after 4 years with that amount of power!) and managed to reach 45 km/h. However, I wanted (and still want!) to go faster. I found a non functionning E300 on Marketplace for almost nothing and this was mandatory in order to put a larger motor (1000W from AliExpress once again). No CycleAnalyst on my scooters, but I don't have a need for one at the moment with only a regen and throttle lever both which are connected via JST to my v3 Baserunner L10. That regen is so smooth and I was in the game long before Apollo which introduce the "first" regen with their City 2022. Programming the throttle curve in the Phaserunner suite makes this DIY scooter so much smoother than any high end scooter I tried (Phantom v2, VSETT 10+, Mercane Widewheel, etc) the fact that it's a FOC based on torque makes the acceleration so smooth! The biggest change was really making that custom battery (more info below). I can't describe how sketchy it is to ride a scooter made for kids with 8" wheels without suspension (check the Youtube link) but this is sooooo fun! People don't understand how I can fly on such a small scooter going twice as fast as Ninebots. They are still a lot to improve, but I go to work each day alternating between the E200 and E300 and because of that frame rigidity, they are basically undestroyable!

Rans Seavo Tandem Recumbent

2023-07-28 | 580 views

My wife and I love riding our tandem 'bent but hill climbs are a granny-gear slog in this seating position, and we live in hilly New England. The bike is pretty heavy and the weight of the bike, two riders, and cargo is often close to 450 lbs (200kg), so I knew we'd need a heavy duty motor. I went with the TSM-A5 rear direct drive hub and a 36V 24a battery with the latest baserunner and cycle analyst. It worked out great! Now, we fear no hills and we find ourselves riding more often and over longer distances. One other challenge we had with this tandem is getting the whole thing moving. There's a little cooperative dance we need to do to start rolling from a dead stop so it takes a few seconds. This can be terrifying if we're trying to cross a busy street. With the motor, I just blip the throttle to get us moving across the intersection and we don't have to panic trying to get our feet in the clips. The built-in torque sensor was one of the main reasons we went with this motor. This was our first ebike but I test rode a few, and using cadence to determine assist level just felt really unnatural. The torque sensor is a massive improvement and makes us feel super-human. We also really like the regen capability. I barely use the brakes any more - the regen is just super effective. We set a 25mph (40kmh) speed limit which keeps our speed down on even the biggest hills with no braking. Hayley at Grin was a vital contributor to this project both pre- and post-sale. This is an unusual bike so I wanted to make sure everything was going to fit before purchase. Thankfully it all worked out great and we're very happy with our new ride! Thanks again, Hayley!

The WindWheeler is a recumbent quad or Velomobile that is not only powered by human and electrical power but is also wind-powered by means of a wing sail. At wind propulsion, the maximum speed is controlled by using proportional regenerative braking (Cycle Analyst combined with the Baserunner controller), so you never go faster than the maximum speed and at the same time, you regenerate wind power to recharge the battery.

Brompton Green Machine of Fun

2023-07-27 | 487 views

Up next is my trusty steed, a 10-year-old Brompton that has been my faithful companion in the journey of life. Despite its age, the bike is in peak condition since it's had a transformative journey itself. Over the last decade, each and every part of this bicycle has been replaced, not because of wanting or needing more, but over the natural course of life and new beginnings, gradually transforming itself to a state of sublime performance. When you look at this bicycle, you're not just seeing a decade-old machine but a carefully maintained and diligently updated project of love. It began its life as a standard Brompton, straight from the factory, brand new and gleaming. However, it didn't stay in its original state for long. From the saddle to the pedals, the brakes to the gears. The end result is a bicycle that maintains the classic Brompton charm while boasting all-new parts that have kept it fresh and efficient. My favorite part is the Grin Tech electric conversion that has transformed this Brompton into an electrified marvel. Combining the convenience and compactness of a folding bike with the power of an e-bike, it presents an upgraded commuting experience. This isn't just a bike, it's a versatile companion thats been with me for all my chapters. This bicycle's odometer displays a remarkable 10,000 miles. It's not just about distance this Brompton has seen two different continents, varied landscapes and cultures along the way. Each mile added to the odometer represents a story, a piece of a larger narrative of adventures and discoveries that span across different parts of the world. Overall, this 10-year-old Brompton folding bicycle is a testament to the power of continuous upkeep and innovative modifications. It has been crafted and cared for with love, passion, and a deep respect for the spirit of cycling. What you're getting isn't just a bike—it's a decade of memories, a steadfast companion, and an expertly-upgraded machine ready for new adventures.

After a knee accident a few years ago I found I could not ride for more than a few kilometres per day but wanted to go further. I have fitted the trike and trailer with 480 watts of solar, a Bafang motor which I like to control with the Phaserunner and Cycle Analysts and other parts I have got from Grin Tech. I am currently making a support for my left leg and will be peddling with the right leg. I plan on riding the length of New Zealand, from Cape Reinga in the north to Bluff in the south this summer as a test run, a distance of about 2,500 kilometres. If all goes well I am inclined to cycle across Australia from Brisban to Perth the following year. Who knows I may not stop there but continue my journey home the long way around heading west. The trike meets all the guidelines set for The Suntrip and was inspired by Justin and Anne-Sophie's 2018 Solar Ebike Suntrip Ride from France to Iran.

I strapped a 35-Amp Grinfineon controller to the twin support frame tubes under the seat. The long wires that came with the controller and motor fit perfectly.Even the full twist throttle wires ran all the way from the chopper bars to the controller. The CycleAnalyst fits down low on the chopper bars to keep a clear sight path out front. A small reed switch glued under the brake handle provides cut-off and flips me into regen mode for some extra braking. The 52V 20Ah LiFePO4 battery is tucked securely in a plastic, waterproof, lockable ammo box from MTM. The ammo box comes with an ATV mounting kit that is strapped securely to my back Rans recumbent specific pannier rack. A couple of years ago, I upgraded to the large-display CycleAnalyst and I have cruise control and variable regen braking now, I have to keep my MAX amps limited to 25 amps to keep it safe and extend battery life.

All wheel drive handcycle

2023-07-27 | 492 views

I use two Grin all-axle motors to power the rear wheels on my handcycle. This has been a complete game changer as a common issue I was experiencing is the drop in traction when going up hills as the steeper the hill the less weight I have on my front wheel. This prevented me from being able to bike on fire roads. With the two motors in the rear I know gain traction as my weight distribution increases on the back wheels. This allows me to go up steep gravel roads and enjoy mountain biking with my sons (something I never thought I could do). I was even able to bike up ski slopes with two fat tires in the rear. This bike is part of our electric assist handcycling program, ablebodied.org, where we offer free lessons to anybody who cannot ride a regular bike. We primarily have riders with spinal cord injuries, but have also had riders with MS or knee issues. The all wheel drive handcycle allows our riders to go places they would otherwise never be able to get to.

Bike Friday Haul-a-Day

2023-07-21 | 539 views

Was lucky to find a used Bike Friday cargo frame and built myself a second vehicle for commuting and errands. This bike has the older version of the Mg311 front motor with pedal assist. It’s a smooth and dependable ride. I love the integrated light and long battery range. Drive train and other parts were in short supply during the pandemic so it ended up with several unintended upgrades which make for smooth shifting and braking. Did the install myself and had a local bike shop check my work!

Last year I decided to buy an ebike to get further out of Quebec city center and also go to work with my bike and not be all sweaty. I really liked my actual bike and I didn't have the space for a second bike in a tiny apartment so a conversion kit was the best option. I went with an All-Axle front motor, a Frankenrunner controller, a cycle analyst and a 72v/9.5A battery. Yes the battery is backwards, more details bellow :D

It’s an electric chopper designed with my teenage son with the specific goal of not looking like an e-bike. We spent months and months searching for batteries that were modular and that’s how we found Grin. Using the Grin system as the electrical foundation, we worked with The Cruiser Shop in Campbell California to build this up with the specific aesthetic of marrying it with the computer term bare metal server. So we wanted literally nothing extra right down to using powder coating on the frame so we could should off the beautiful heat marks around the welds. This bike is the embodiment of form is function and engineering. My girlfriend loved it so much we built up a similar one for her… that’s painted with a gas tank and the opposite of the original.

Ye Olde EbikeE CT

2023-07-17 | 496 views

The core of this project is a bikeE CT, in faded red. It was a gift from my mom around the year 2000, and was basically stock except for a replacement stem and handlebar to widen it so it's not the original bikeE Squirrel bars, with your hands very very close together. Then a friend introduced me to the wonderland that is Grin and electric bicycles. I had been previously tempted, in my uninitiated ignorance, with a gas-powered assist motor. What a fool I had been! Unicycles on the wall, with motors? What? So many cool electric and even non-electric vehicles, I was in awe! I don't remember the specifics of the parts, other than they more than likely came off the cheap shelf. It's a v2.23 CycleAnalyst with a NineContinents Pre-RH212 motor and a Grinfineon controller, finished with a pair of ebrake levers and a full-length throttle with built-in ebrake button. The Grinfineon cheap-shelf controller was eventually diagnosed as the source of my teething problems, and so it was dumped for a Phaserunner MT in Silver, with ebrake connector added to compensate for the v2 CA. The batteries are pair of eZee Flat 36V, stored in the pannier bags, which unfortunately eat most of my carrying space. I think they were 14Ah each, and have lost a lot of juice over the years. They still do get me where I want to go, but only barely. I've tried to install them in the eZee racks, but they are an older version of the battery case and won't quite fit without force, so I'm stuck with panniers until I figure something else out. Given the weight distribution of the bikeE in general, the best place for the batteries would be strapped under the frame between the pedals as far to the front as I can fit it, so maybe that's the next upgrade! I admit I don't commute with it as much as I could, but that's because of terrible and unavoidable construction near work on King George highway, and the frankly terrifying Alex Fraser bridge. Other than the motor showing it's age and the CA lacking features, it's a very smooth and comfortable ride! I could use a bit more acceleration at points, and a fairing, but there are always things to add and make better! #HackThePlanet Thanks Grin Team!

Touring eTrike Build

2023-07-17 | 695 views

This is my favourite touring vehicle - a Performer JC-70 recumbent trike with a Grin kit comprising of an RH212 motor and a Baserunner L10 controller. The Baserunner allows regen braking, which is fabulous for recumbent trikes as they have very low wind resistance and quite a bit more weight, so there's plenty to be recouped in regen. The low wind resistance also allows for very low power cruising - at 30-35km/h, I get about 5Wh/km which is about half the average ebike. These together translates into very good range - I have a theoretical 200+ km range on the 52V 19Ah battery and have done over 160km on a single charge with quite a bit to spare! I also wired this vehicle so that I can e-brake with a single press of a button and throttle with it for proportional regen of up to 1200W. There's also a reverse feature at the press of a button, along with a 48V motorbike horn and some seriously bright headlights and taillights for safety. I love touring on this things - it's so relaxed and covers ground so rapidly. I recently did a 2 day 260km ride on this without even feeling tired at the end of it!

Built for a long, hilly commute. The route includes bike lanes, city streets, back roads and MUP bike paths. For most of the way I need speed, but some of the MUP are limited to Class 1, 20 mph. I go slow on the MUP, but it's best to keep from looking like an aggressive e-bike. SX1 front hub, baserunner and CA3, simple PAS, 62 cm Soma Buena Vista frame, 8 speed Alfine IGH rear, Growtac cable discs. A custom frame bag from Waxwing holds pump and tools, a home made wrap covers the battery. My previous bike was a BBSHD mid-drive. I expected the front hub to be less capable, but except for steep hills it is fine. I go just as fast, but use only 10 - 12 Wh per mile instead of 15 - 18 on the BBSHD. The mixte frame made the cable runs very clean.

A sleepy Giant Simple Three converted to a stealthy E-bike. My goal was to build something that has enough range that I would never have to worry about running out of charge, more power than anything bought in a store, and won't draw attention. All in, this project took nearly 2 years to complete. The custom built aluminum battery box holds a 52v 50A pack built with Panasonic 21700 cells and a Frankenrunner mounted to the bottom with all wiring concealed inside for a clean look. Rear wheel is laced to a 9 Continent RH212 standard wind motor. Brakes were upgraded from coaster to 180mm Avid Level disc brakes. Other parts include ERider torque sensor, Cycle Analyst V3, Halo headlight with high beam, Brooks B67 saddle, Salt Plus Warlock chain, and an ATV style throttle with long throw for finer throttle control. Specs: Peak Power: 3300W/63A (Limited due to phase over-current faults at higher output) Max Regen: 1400W/25A (Limited to reduce stress on pack. 85% of max cell charge current) Top Speed: REDACTED Range: 250KM easy riding, 120-150KM hard riding As of July 2023: Odometer: 7000KM Power Consumed: 125KWh Rear Tires Replaced: 3

The hub is a direct drive 9 continents hub I got a few years back. Regen braking provides most stopping power, vbrakes are good in an emergency. I have 4 × 20 ah 48v homebrew batteries. Each battery gives me 50km range. The gears are selected to allow me to peddle 40kph, meaning I can still be getting a workout whole bike is at top speed. I have been commuting with this bike for almost three years now. This trailer is a new addition. The dropouts of the front wheel gave out, causing me to have to rewire the motor. I managed to beef up the new dropouts with 3/8" thick steel. LEDs are powered by a 48v-12v converter and blinker module usually used in cars.

2023-07-15 | 474 views

This is an EbikE CT from the early 2000's. It was initially converted in 2014 using cheap components that eventually died or were replaced over the years with better stuff from Grin. Now it sports a Cycle Analyst V3, RH212 and Grinfineon controller. It is also charged using a Satiator charger. It also sports a slim, internally mounted battery (14S5P - 18650 - 850Wh) I built myself which has delivered over 20000km and 500+ charge cycles and even with degradation still gives over 55km range with the more efficient Grin products. Future plans for the bike are to add a second, external battery and eventually replace the internal one. The solar CA was also considered, however the bike is often left charging via Solar when switched off so this was discounted. Photo's show the bike at various stages of build over the years, showing some smaller solar panels, shorter seat-back and it's original golden motor, now replaced with a RH212. Efficiency is around 13-15Wh/km with the Solar panel actually improving aerodynamics at a cruising speed of around 40kp/h.

Grins Cargo Trike

2023-07-14 | 633 views

This project was Christiana-inspired trike that we commissioned as a hauling device for transporting packages from our small shop space to the post office. A critical design criteria is that it had to fit through the doorway of the shop so that we could load it up with boxes, requiring the wheels to be inbound rather than outbound. Segue of Frankentrikes did the mechanical build fabrication in 2007 using from scrap metal from an old bed frame and salvaged bicycle components. The dual front motors, controller, and battery system have been upgraded numerous times over the years. While Canada Post now comes to us, the trike is still in regular use at Grin some 15 years later as our primary means to haul scrap metal to the recycling yard.

Sociable (Side by Side) Tandem Ebike

2023-07-14 | 681 views

This project was inspired by from a library book on bicycle history which showed a 2 wheeled tandem bike with the riders side by side! We thought that was such a neat idea, and decided to build one for fun using two bicycle frames pulled from a bicycle scrap yard. Originally not electrified, we eventually added motor power with a Crystalyte 408 hub motor. The ride experience was an interesting dynamic as both riders shared the same handlebar and could equally contribute to the steering. The bike was taken to Burning Man, VEVA REv! shows, Critical and Maker Faires but then sadly got stolen from the back lane when Grin moved headquarters from Main St to False Creek in 2011. We have no idea where it is today

Justin's First Ebike Build

2023-07-14 | 663 views

This is the first bike build that I completed in 2003 after discovering the Yahoo Power Assist group and the small but burgeoning community of DIY ebike builders that existed at the time. The Crysatlyte 400 series rear hub motor and 20A controller were purchased used from Joshua Goldberg in Toronto, one of the first people to be importing these early direct drive hubs into North America. The battery pack was cobbled together from surplus NiMH cells that were pulled from old laptop batteries of the era, and held tight to the bike with tape. There were no ebike displays at this time so a multimeter was affixed to the handlebar to see how much power I was pulling and let me look at the battery voltage. This eventually became the seeds for the first Cycle Analyst devices. My main motivation for this project was to have some inspiration to get up and climb the large hill to university and not be late for my 8am morning classes.

72v E-BMX!

Turned a rare 22inch BMX into a Pocket-Rocket! Used a Phaserunner and 72v 8ah Battery with Samsung 40T Cells giving the bike a peak power of 2600w! Headless system with one throttle and a separate brake input to activate regen in the rear hub to aid with braking. Lots of custom fabrication work went into this build, the battery was an extremely tight fit! We settled on a design that would allow the battery to be bolted in, and remveable only for service. The rear end was also lengthened slightly to make room for the motor, and to add stability at speed.
