Summary

    GMAC rear hub motor kit with optional battery pack and your choice of a Baserunner or Phaserunner motor controller.  If a Baserunner controller is selected along with a downtube battery pack, we will mount the controller inside the battery cradle for a very clean instal.

    The GMAC motor has a 5:1 gear ratio and no internal clutch, allowing for regenerative braking capabilities that are not typically available with geared hub motors. Features 0.27m laminations, an integrated splined torque arm, and a Shimano HG compatible freehub system. Motor OLD is 138mm and fits in most bikes with slotted dropouts. 

    The barebones system uses a throttle with an integrated on/off switch and voltage readout that is compatible up to 72V, but doesn't have a proper display or options for PAS / Torque sensors. This makes it great for simple and clean ebike builds that want to avoid any additional complexity.

    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.
