This speed sensor with a Y-splitter is specially designed for Tongsheng TSDZ2 and TSDZ2B mid-drive motors.
It combines the standard speed detection function with a dedicated output for lighting, enabling a front headlight and a rear light to be powered directly via the motor.
The 6 V / 3 W output is compatible with most standard e-bike lights, and the lighting can be controlled via the display (VLCD5, VLCD6, XH18, 850C, etc.).
Ideal for neat, integrated installations, this system eliminates the need for an external battery or a separate power supply for the lights.
