Minshine BK-ES Embedded Brake Detection Sensor

The BK-ES embedded brake detection sensor is a new-generation brake power cut-off component specially developed for electric bicycles. It adopts a through-cable structure, the brake cable can be directly inserted into the sensor body. When pulling the brake cable, the sensor accurately identifies the braking action and outputs switching signal to cut off motor power for riding safety.
