The Bafang BBS02B 750W is the most popular high-power mid-drive on the market, delivering 48V 750W and a stout 120Nm of torque through your drivetrain for serious off-road climbing and acceleration. The bottom-bracket mounting keeps weight low and central while letting you exploit your bike’s gears for hill work the hub motors simply cannot match. Supplied with pedal-assist and a full hand/thumb throttle, plus motor-cut-off brake levers, gear sensor, colour display, PAS sensor and complete wiring loom. Fits a standard threaded BSA bottom bracket. For off-road / private land use only — not road-legal in the UK. With 750W output and a full throttle it exceeds the UK EAPC limits and may only be used on private land or off-road with permission.
