MG311 Standard Wind 26"
Bafang G311 Front Geared Hub Motor in 26" Alex DM18 Rim. Standard Wind (8.4 rpm/V).
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 is laced in a 26" Alex DM18 rim and includes an internal 6-pole speedeometer sensor so it can use a CA-DP device and not require an external speedo pickup. It has helical cut gears on the initial reduction of a double stage planetary gear set and is exceptionally quiet for a geared motor. This hub is wound with a moderate speed winding (8.4 rpm/V).
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. For more details, see the G31X Geared Motor Info Page
