The Bafang G311 motor is a compact disk compatible 2.3kg front 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 speedometer sensor so it can use a CA-DP device and not require an external 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 fast 10.5 rpm/V well suited for 16" and 20" wheels, but can be used in fast 26" and 700c setups as well. 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.
