Feature: 1. Dual Hall Sensors: The electric bicycle assist sensor housing has dual Hall sensors to detect the running of the bicycle. 2. 12 Magnets: With 12 magnets, the accuracy is higher than with 5 magnets, and the distance from the sensor becomes longer. In terms of sensitivity, it is 2-3 times higher than ordinary 5 magnets, and there is no false action. 3. Pulse Signal: Installed on the right side of the pedal by default, with 12 pulses in a circle. The chip screens 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 output a pulse signal, and the LED is at a low level (with or without a pulse signal), so the LED will not flash. 5. Features: Made of high quality material, strong and durable. Professional manufacturing, stable performance and high reliability. Easy installation and disassembly, waterproof interface.
