Re: New "TSDZ2 Torque Sensor Central Motor"

I fully agree with christian. the problem of the torque sensor is the groove for the ring that fixes the bearing,this groove makes torque very weak.tongsheng engeneers must improve it.us torque becomes unusefull after braking the cheapest solution can be solding the ring directly with no groove.

If you want to know the symptoms when your torque sensor is broken:

.When you press the pedal and stop the motor continue working a time
.you feel more power assist than normal
.your battery lasts minus
.when the torque is full broken you feel irregular assist
