Oh I'm very mechanically inclined if you see the bike and you would say wow even I'm impressed but what happened is the the axle that came on the motor could only go on a certain way so it doesn't three wheel and the washer that went with it to lock it in place didn't fit on my bike it was diagonal when I couldn't get it in the slot so I just put the washers but after tightening the first time it kind of come off it never has come off I was changing the tire on it and I thought I turned it down tight enough but I did and it wrapped around like three or four times I've got where I can see the wires I didn't know there was that many in it but I will get it apart and solder if I have to
