Bafang Brake Levers with cut off switch Premium E-Brake levers (Pair) for the Bafang BBS02 750 watt electric bike kit and the Bafang BBSHD 1000 watt Electric bike motor kit. The eBrake levers are easy to install and come with a motor cutoff feature. The Bafang BBS02 and the BBSHD are very powerful mid drive motors. When you brake by squeezing the brake lever a sensor automatically shuts off the motor. This is important because if the motor does not shut off you will be trying to brake against a 750 watt or 1000 watt motor! This will quickly wear out your brake pads and can be dangerous.
