The Bafang G311 front motor is a compact disk compatible 2.3kg rear hub with a nominal 250-350 watt power rating that works great for stealthy systems that do not require significant assist for steep hills or cargo. This motor includes an internal 6-pole speedeometer sensor so it can use a CA-DP device and not require an exeternal speedo pickup. It has a spiral gears on the initial reduction of a double stage planetary gear and is exceptionally quiet for a geared motor. This hub is wound with a moderate speed winding (8.4 rpm/V) for 26" and 700c wheels.

Uses 9-pin overmolded Higo Z910 waterproof connector for the motor phase, hall, and speedo wires. Has internal tabbed washers for anti-torque rotation with the dropouts and a round 10mm axle. Does not work with conventional torque arms.
