Grin Kits

Grin Kits

Standard All-Axle

Our regular All-Axle hub motor kits fit virtually all normal sized bicycles and trikes with both slotted and thru-axle dropouts. At 4kg they are among the lightest direct drive motors in their power class, with the rear models featuring an integrated torque sensor for simplified installation.

Max45 All-Axle

The Max45 motors have a wider stator than our standard motors and are correspondingly heavier (6kg) and more powerful. They are designed to fit all fatbike dropout standards. We also have a rear Max45 Freewheel model for regular cruiser and chopper bikes that run a single speed chain.

Dual All-Axle

Dual motor systems are useful when extra power and hill climbing is needed. You can run dual front/rear motors on a normal bicycle, or dual single-sided front motors on trike and quad vehicles.
