This extension cable (or speed sensor, depending on the version chosen) is designed for Tongsheng TSDZ2 and TSDZ2B central motors.
Allows you to extend the connection between the motor and the speed sensor, or to replace the original sensor altogether.
Essential for accurate speed reading, this component ensures the smooth operation of the electric assist and compatibility with VLCD5, VLCD6, XH18 or 850C displays.
The extension is particularly useful for long frames, atypical bikes or assemblies requiring special cable routing.
