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. 

Thanks in part to an unexpected article by the ebike champion and educator Micah Toll, we've found found ourselves being flooded with interest in our new GMAC Hub Motor series. Well we're glad to say that after 2 years of development testing and design iterations, the goals we set out to achieve in partnership with MAC motors for have been fully realized. It's time to properly introduce the GMAC motor now in full production:

A powerful regen-capable geared motor, with integrated torque arm, round axle, side cable exit, cassette freehub, and no clutch. Enjoy!

We hope all of our northern customers have been having a great Canada Day long weekend. If you've gone on an ebike powered camping expedition then send us your celebration pics!

For the next week we have a flat 15.2% discount on all our flagship made-in-Canada items (Phaserunner, Grin All Axle motor, LiGo batteries, dc-dc converters etc). Simply use the coupon code "Canada152" at the checkout.

Just a note to everyone that Justin and Anne-Sophie are now back from a 6-week leave after bringing a little baby girl into this world. Her name Andina was inspired from AnSo's unicycle trip across the Andes, and it's going to be a delight for us to join all the other young families who've been raising a kid from the seat of a cargo bike rather than the backseat of a car.

Anyways if there's been a lack of updates on the site that is why, and we want to thank all the staff at Grin who've been keeping things running and flowing during this very busy time of year. More good stuff (videos, new products, web updates, clearance sales) coming soon.

A trade show we've been dying to attend one of these days is the Spezi bike show happening next weekend (April 27-28) in Germany. This is where all the oddball, unusual, and otherwise special bikes get showcased, and if anyone's been keen on electrifying wheeled oddities it's us!. 

While we won't be there in person, a number of vehicles will be at the show featuring the new Grin products like the GMAC Hub Motors, RH212 direct drive motors, All Axle hubs, and the Baserunner and Phaserunner_L10 controllers.  If you're lucky enough to attend then check out Booth A.18 and Booth 3.12 for some velomobiles and cargo vehicles running this gear.  

The timing is also great for us to formally announce an updated 2019 version of the Grin All Axle motor suitable for these single side applications, as explained in this new video below.
