Fits 95% of standard bike frames with 68-73mm bottom bracket 30% lighter than a Bafang motor for almost the same power output Built-in torque and cadence sensor - this results in much smoother acceleration than any cadence sensored mid motor Easy to install. Kit includes all installation hardware and tools The motor has an extra support mount - resulting in a much more reliable install than a Bafang BBS motor

New Version: TSDZ2 Updated to TSDZ2B Which has two clutches designed on the main gear. Main gear is disengaged from the chain during riding, so it feels as easy to ride as a bicycle. It increase the center positioning, which ensures the radial spacing accuracy. It also improves waterproof performance. After changing to a new integrated part, the life of the engine is increased
Power & RPM: TSDZ2B 52V 750W 4500rpm mid mid drive motor kits. Fitting most standard bike with 68/73mm length bottom bracket, only fit for the bike with disc brake and chain drive system, if you need it to fit 100mm or 120mm bottom bracket frame, pls send us the message before ordering
Torque Sensor: Resister strain technology to check torque signal, digital wireless data transfer, high sensitivity and stability output. The combination of the detection accuracy of the torque sensor and the reaction speed of the control system makes the torque output waveform perfectly close to the torque waveform outputted by human power, and makes the motor force always change linearly with human power
Independent Controller: Compact modular design, Synthetic step frequency sensor, outer shell, water-proofing glue, no intermediate connector for higher reliability
Safe Design: The power output is synchronized with the pedal, as long as the driver releases the pedal, the power will be cut off immediately, and there is no need to install the brake levers. When the crank is idle, the motor does not rotate. It's as safe as a bicycle
