After riding my new rad city bike like less than two blocks, the controller died. Rad Power bikes have been extremely cooperative helping me troubleshoot my problem and have sent me a new controller. Tony (tech support) told me to contact the four wires from the controller to the connectors going to the battery and motor. The big problem is there are three connectors and the fourth wire disappears into the frame and is inaccessible. Does anyone know how I can access the wire going into the frame to connect the new controller.
