Version 3 for You and Me

The busy bees have been at it this winter and have got the V3 release of both our front and rear All-Axle motors in full swing.

What's New?

This includes support for more dropout standards, more drivetrain options, better cable clearance, and most critically it adds integrated torque sensing to the rear hubs. That gives both full backpedal regen capabilities and torque sensing control without any need to install a bottom bracket sensor making installation a real breeze. You can read about the details here or just let the video do the talking!

Introducing Grin's V3 All-Axle hub motor series. SRAM XD, torque sensing, and Fat Bikes included


We've also completed the full owner manual and have made 3D CAD model exports with all the different adapter configurations for people who like to do full modeling of their project build and motor integration.

The V3 hubs are listed on our store page by themselves or as components of full conversion kits. Our manufacturing team is having a hard time keeping them on the shelf so if the store page says "back-ordered" just place the order anyways to get in the queue as they come off the line.
