Tongsheng TSDZ2B Speed Sensor

Tongsheng Speed Sensor (single) for use with Tongsheng TSDZ2B mid-drive motor.

* Before buying this (if you're assuming your unit is faulty because the speedo is jumping all over the place), please ensure you have the magnet at the correct distance from the sensor (8-15mm), if its too close you'll get this fault.  Doesn't matter if you have to rotate the pickup sensor somewhat to get more distance.  Ensure that the magnet is passing the correct part of the sensor pickup unit.
