    Complete conversion kit based around the Shengyi SX2 mid-sized silent geared hub motors, including the baserunner motor controller tucked neatly in a downtube battery, the CA3 with accessories and pedal assist systems. The motor has built in speed and temperature sensing for automatic thermal rollback with the CA3 so that there is no risk of burning up the motor on long climbs.

    This setup includes everything configured out of the box for a lightweight commuter ebike with pedalec control.
