Function: 1. Dual Hall Sensors: The electric bike assist sensor housing has dual hall sensors to detect cycling. 2.12 Magnets: With 12 magnets, the accuracy will be higher than with 5 magnets, and the distance to the sensor will be longer. In terms of sensitivity, it is 2-3 times more than the usual five magnets, and there is no bad effect. 3. Pulse Signal: Installed on the right side of the pedal by default, with 12 pulses in a circle. The chip shields and identifies the pulse signal to determine the direction of rotation. The forward direction is valid and the reverse direction is invalid. 4. LED: When the pedal moves forward, the sensor will send a pulse signal and the LED is low (with or without pulse signal), so the LED will not flash. 5. Characteristic: Made of high quality material, strong and durable. Professional manufacturing, stable performance and high reliability. Easy installation and removal, waterproof interface.
