ENM 406130984 Tongsheng TSDZ2 Mid Drive Motor 36V 48V 52V 350W 500W 750W TSDZ2B Torque Sensor Electric Bike Motor E bike DIY Conversion Kit For BB68/73 MT
[Standard Universal]-- Fits most standard bike with 68-73mm bottom bracket, only fit for the bike with disc brake and chain drive system. [Torque Sensor]-- 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..syi
