News

Our Grin battery lineup keeps growing and the latest shipment includes high capacity downtube batteries in the new Reention DP-9C 84 cell enclosure. These large packs provide over a kilowatt-hour of capacity in convenient frame mounted casing, ideal for long distance trekkers.

We have both a 36V 26.5Ah and a 52V 20Ah model in stock and ready to ship. We've also got a smaller 48V 16.5Ah Reention battery model for smaller range requirements. These 3 new models are all Baserunner compatible for slick conversions and are available with our Ready-to-Roll kit bundles

72V are Shipping

Last year we expanded our 72V pack offerings to include a 9.5Ah model using Panasonic 21700A cell, but they were for local customers only as we lacked the paperwork and certification to ship them. Well that has been sorted out and these 72V downtube battery packs are now available to be delivered around the world. These packs provide a very convenient approach to doing high speed EV builds without the complications of series connecting 36V batteries or dealing with sketchy pack construction.

LiGo+, Higher Power

We're also putting on the final touches for a new LiGo+ battery module that uses the high power Samsung 30Q cells. These new LiGo+ packs can sustain higher continuous discharge currents (15A vs 10A) and charge currents than our standard LiGo, making them ideal for very lightweight EV builds that are running just 2 or 3 of these modules. For large packs (4 or more in parallel) the standard LiGo batteries are still perfectly suited and the most economical, but for more ultra light systems the LiGo+ packs are just the ticket. .

VIMFF - Feb 26th

We're thrilled to report that the Vancouver International Mountain Film Festival (VIMFF) has selected our short film "3 Wheels Under the Sun" for their upcoming show. This tells the full story of our 2018 Suntrip race and will hit the big screens on Feb 26th at the Rio Theater along with presentations from other long distance bike tours . We welcome anyone in Vancouver with an interest in bike adventures to get tickets now. If you're into the outdoors be sure to check out the many other great shows during the 10 day festival.

BC Bike Show - Feb 29th / Mar 1st

We'll also have a screening the following weekend at the BC Bike Show on Feb 29th at 12:30pm, and March 1st at 3pm. This will be a more intimate environment that will allow discussions about the logistics of solar ebike touring and a Q&A session afterwords. If you are interested to hear more details about solar powered ebikes or have some burning questions then please come out. There are plenty of reasons already to check out the BC Bike Show and hopefully this adds one more to your list!

As we move fully to the L10 motor connector standard for medium to high power kits, we've decided to slash prices on all our remaining motor and controller inventory that use the Powerpole standard. This is your chance to get a great deal on high performance kits at 30-40% off the regular price, and it includes all of our eZee kits and the prelaced Crystalyte UFO kits.

The motor Anderson and JST plugs and standard has served us well for over 10 years, but we're trying to reduce the overlap as our upcoming eZee and Crystalyte orders will all be with the overmolded L1019 connectors.

We hope everyone out there who celebrates is having a great Christmas holiday.

It may not be peak ebike riding season but it can sure be prime building season! We're wrapping up several months of serious work behind the scenes at our shop and are glad to announce a few things as the year comes to a close.

RTR Kits

First and foremost, we've expanded our selection of Ready-to-Roll kit bundles based around the new Baserunner controller series. Including many high power hub systems now that we have the Baserunner_L10 in full production which supports 80A peak phase currents. Check the video below.

All Axle Fun

We're also happy that report that our Grin All Axle hub motor is out of the Beta testing phase and in full release with an updated V2 model. We want to thank all those pilot users from the past several years as we worked out all the kinds, and all those single side trike pioneers who helped us develop a series of adapters for so many trike models. (and yeah, it goes without saying that we are working on a rear version next)

There are more end-of-the-year product treats too. We've got motor options for the 190mm fatbike frames, super secure double and triple bobs coming off our CNC mill for mounting downtube batteries, wheelbarrow and scooter motors for non-ebike conversions, and a few more 72V and 36V battery choices too.

Reading documents

With a wider audience of first timers getting into ebikes as the movement spreads, we also thought it was about time to publish some more entry-level information for people those just getting started.

1. Don't know the difference between a torque arm and a mosfet? Here is a basic primer on all the components that make up an ebike conversion system.
2. Not sure what hub motor options would be compatible with your bike build? We've written a thorough compatibility list for all the different styles of bikes and trikes and what does and doesn't work. 

Well it's been another huge and busy summer, and now that it's mostly wrapping up we're planning to spend the next several months on some deep reorganization and renovation of our shop space. During this time we will operate in business-as-usual for all our online orders and email tech support. However, the storefront will be closed to casual walk-in visits except by appointment only, and our phone may unresponsive for long stretches of times too.

These updates to our facility will allow us to grow and operate more efficiently in the years ahead, and we thank you for your patience during the process. 

For local customers wanting to purchase items, the process will involve placing the order online first and then coming by to pickup the order after you've been notified that the items are ready to collect. 

In our quest to make hub motors keep up with changing frame standards, we've just released a custom version of the Crystalyte 'H' series UFO motor that is compatible with rear thru axle bike frames. We have the rear H3540 and H3525 motors in a 142x12 standard, and a wider H4040 motor available for the 148x12 boost size. 

These motors have an integrated torque arm and we've designed a special CNC machined aluminum frame clamp that provides a versatile means to secure the arm against rotation. They open up electrification options for new bike frames that have adopted the thru-axle hub standard, using the rugged and time proven Crystalyte motor series. 

They are using the L1019 plug standard and are available as part of a complete kit package as well.

Our final event to attend this summer is the annual VEVA Electrafest show, happening this Saturday from 10am to 6pm at the Vancouver Roundhouse. This show dedicated to all electric vehicles has been going on annually for several decades and is really taking off now that EV's are finally coming of age.

We'll be there with an outdoors booth and a number of interesting ebike conversions available to test ride, ready to chat and answer any questions. 

We're hoping this everyone is out having a wonderful BC day long weekend right now. Next weekend, on Aug 10th, our friends at the Sidesaddle Bike Shop are organizing a small cargo bike festival from 10am - 3pm. This could be a fun meetup for those in the city with cargo bikes to hang out, and a great opportunity for those considering getting one take some test rides and talk with firsthand users about their experiences. We'll be there with some from our own fleet of ebikes optimized both stuff and passenger hauling for people to try, and will be happy to answer any electrification questions that come up.

If you've visited our shop this summer you've likely noticed that things can be really really busy. It's a wonderful problem to face and in order to help us maintain our high standards of customer support and product support need more people working at Grin!

We're looking to bring on up to 5 or 6 new recruits in the areas of manufacturing, packing/shipping, accounting/bookeeping, and sales/support. If you are already living in the Vancouver area and see yourself or someone you know fitting in with our culture and mission, please get in touch with us by email. There's a brief description of what we are looking for in the jobs/careers page.

We're in the midsts of inventory suffling right now especially as we transition over to the new L1019 connector standard, and that means a lot of savings and discounts with the remaining Anderson inventory:

MXUS Motor Sale

Now that we have the 9C RH212 direct drive motors in full stock, they'll become our new standard budget direct drive hub, and the remaining MXUS cassette motors are all 25% off. Same with our remaining 9C+ front motors.

eZee Kits:

We've also put a 15-18% sale on all the eZee hub motor kits in anticipation of having an L10 connectorized version of these later in the fall, so now is a fantastic time to get one of these venerable high torque geared motor systems at a discount. 

Stokemonkey:

We're also retiring the classic Stokemonkey kit as we move to focus entirely on hub motor drives, and have our remaining inventory at 50% off and more. If you're looking for a real classic drive system for a cargo bike this could be your chance for bargain shopping.

New 21700 Battery Options

Plus, we've recently expanded our downtube battery selection to include batteries based on the Panasonic NCR21700A cells. These are the same cells used in Tesla vehicles that became available at an unusual discount due to US/China trade issues and so we were able to bring them in and have them on sale in one go. There's a 36V 14.5 Ah, 36V 19.5Ah, and 52V 14.5Ah options, with a new enclosure standard that has an on/off switch, mini 3-pin ST charging port, and Baserunner controller compatibility.

Fatbike Rims Too

We also just received a shipment of the DHL65 rims from Weinmann to further support fatbike and large tire ebike conversions. Unlike most fatbike rims that have excessive left-right spoke stagger rendering them difficult to use with hub motor wheelbuilds, the DHL65 has holes drilled near enough to the centerline that even hub motors with narrow flange spacing can be laced successfully. These rims work well for tires ranging from 3" up to 4.5" in width and are stocked in 20" 24" and 26" diameters with both 32 hole and 36 hole drilling options. Available directly from our Rims catalog or as an option on any kit with a custom wheel build.
