The above installed, rear hub,internal controller,sw-900 LCD display. Code 10 error (communications ) I checked everything ,throttle, halls sensors, still nothing , the motor has never moved. Bought through eBay they are mediating for supplier to voilamart? They came back right away from xxxx miles and said oh it's the controller ,now they are on holiday (Chinese) nothing has been done, they are going to replace controller I believe ,but isn't there a bench test for motor ? A way I can be sure it's the controller I would have to remove my tire and package the whole thing for shipment.any ideas
