Summary

    Grin Fat All-Axle front hub motor kit has 66% more torque and power capability than our regular All-Axle motor and is compatible with most fatbike forks. The Barebones kit uses a simple all-in-one throttle with voltage readout and no fancy display or option for torque sensors.  

    The throttle also includes two extra wires for running a front bike light and hooking up an ebrake sensor.  The ebrake levers provide a fixed level of regenerative braking which is OK, but not quite as nice as the varying proportional regen that is possible with a V3 Cycle Analyst or Superharness kit system.

    • Motor is compatible with both 135mm quick release and 150mm thru-axle forks using appropriate adapter set. 
    • Powerful 45mm wide motor stator but weighs just 6.0 kg.
    • Statorade injection port for maximum cooloing option.
    • L10 connector with internal thermistor
