MG310_700
Bafang G310 Standard Wind (8.5 rpm/V) Geared Hub Motor Prelaced in 700c Alex DM18 Rim.
The Bafang G310 motor is a compact disk compatible 2.5kg 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 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. Uses a cassette freehub system rather than screw-on freewheel and features a side cable exit as well. This is our standard hub motor winding (8.5 rpm/V) prelaced in a 700c" Alex DM18 rim with Sapim single butted spokes.
Uses 9-pin overmolded Higo Z910 waterproof connector for the motor phase and hall wires. Including 6-pole speedometer. For more details, see the G31X Geared Motor Info Page
