Started with the PAS so I changed the B.B. sensor. The PAS would drop out unless you really put a lot of pressure on the pedals. Then the speedo quit which caused the PAS to not work correctly. Then the throttle quit. Bike shop tested my wheel and motor on another bike and it worked fine. Also tested my LCD on another bike and it worked fine. Reconnected every connection. Still nothing. Just tried of trying. So I bought another bike.
