motor suddenly went into reverse ????

[garyv123]

so i have an lectric expedition has 1200 miles on it never had a problem. then today it did a weird jerk then it locked up on me. come to find out both sides of my rear axle had jumped out of the drop outs and got jammed in the forward position and also twisted the wire harness and pinched it in the wedged forward position took awhile to figure out what actually happened thought it wasn't tight and they fell out but no they were ripped out of the drop outs with all its torque so i fixed the damaged wires and put it back together powered up all good went to take test ride it mediately forced out of the drop outs and did the same thing any ideas as to what is going on? is it the controller hall effects it is a geared hub motor doesn't it have a clutch that doesn't allow it to go in reverse? I'm so confused also both times when it got jammed up read error code p008 wich means motor issue so they say

I thought Lectric bikes use geared motors. When these are in reverse, the clutch prevents the wheel from spinning. I've intentionally switched the wires on hubmotor to spin in reverse. It just hums away.

If they've gone and put in direct drive hubmotors then ignore me, never mind.

no its a geared hub motor and i thought the same thing that it cant reverse cause of the clutch but it would seem that way idk what is going on to be honest all new today

Hey Garyv123, I'm new here n your question caught my eye right off the jump. I recently installed a 1200w 48v conversion kit on my mountain bike. It worked fine for the first two weeks then one day I tried to take it out for a ride and the bike nearly came out from underneath me going in reverse. I don't know exactly what caused it, but by switching the green and yellow phase wires fixed the problem and runs good except for battery problems I'm trying to figure out. But green to yellow, and yellow to green worked for my setup. The blue I left alone
