I have tried: taping them together, hot glueing them together and ziptying it right to the frame to prevent jiggle.
All have failed.
Right now, when I reconnect them and apply pressure, I can't even get the engine to turn on anymore. But the speedometer still works and that signal is sent through the engine cable too.
Recently, sometimes the engine rear wheel barely rolls when I roll the bike backwards.
There are no ebike repair stores in my city.
Is this the cable running to the motor? If so, it may be the hall sensors are buggered if disconnect happened while riding. If the plugs are coming loose, then something is wrong with at least one side of the connection and should be replaced (either the wiring harness side or, more difficult) the motor side. Either way, if you can't do that, an electrician should be able to, once you have the parts.
Yeah, sounds like something might be wrong with the motor.
