Gear Shift Sensor for Bafang Mid Drive Motors
This connects to the yellow plug in modern Bafang Motors, the plug directly comes out of the motor.
This sensor will momentarily cut motor power when shifting so that your shifts are much more smooth. This also results in less wear on your driveline.
Not a totally necessary item but a nice touch! Can definitely driving a mid drive motor easier (especially if you are using a mid-high assist level).
You will have to unfeed your shift cable from your derailleur and then feed it through the sensor. You can see pictures for how it can be mounted.
Mount either on the bare cable and hold on place with a zip tie, or put on the end of the housing so that the sensor stays in place.
