BAFANG SR PA Series Speed Sensor Owner’s Manual
INTRODUCTION OF SENSOR
- Scope: It is applicable to standard 68mm BB.
- The material of locking cap is PA (nylon).
This is a speed sensor for the BB (bottom bracket). This high-quality and high-performance BB speed sensor is installed on electric bicycles or tricycles. The CPU processes the speed signals collected by the speed sensor by means of non-contact induction and analyzes the motor operating direction. As the speed sensor (including its PCBA) is integrated within the BB, it is protected from friction and boasts a longer service life.
