One Family, Every Hub Motor You'll Ever Need
The Grin All-Axle Motor is our family of direct-drive motors designed for universal compatibility with all varieties of rear and front quick-release, thru' axle mounting and even single-sided mounts in the bike and trike world today. In one product we:
Solve the compatibility problem between hub motors and modern bike frames
Provide the benefits of direct drive without the traditional heft
Simplify the installation with integrated torque arms and torque sensors
Why Direct Drive?

Smooth and very silent - almost noiseless with no gears to grind

Regenerative braking capable, saving you brake pads and returning brake power for more range
