Tongsheng TSDZ2 kit with VLCD6 display fitted to Orbit tandem. Battery is Hailong 36V 13A. Unfortunately there is no pedal assist! Connected the throttle and the motor sprung into life, however still no pedal assist. So is it the torque sensor or the controller or can anyone suggest something else? Could it be the wrong firmware, e.g. set up for a 48V battery? I will contact the Chinese supplier, the kit came via Aliexpress.
