Convert your 27.5″ (650b) trail hardtail or hybrid with the compact Bafang G310 front geared hub motor. Rated at a nominal 250W with cadence pedal-assist and a 6km/h walk-assist mode only, this kit is road-legal in the UK (EAPC) — legal on roads, bridleways and cycle paths with assist limited to 25km/h. The front-hub design leaves your rear drivetrain and brakes fully standard, so fitting is straightforward on most disc or rim-brake forks.
