    Chain problems

    Hello, My son and I built a motorized bicycle and the back wheel doesn't move, My son says he can hear it happening under the base plate where the chain goes in the engine. When I look at the chain sprocket on the engine it seems to be getting caught on the base plate itself, I tried to ride it...
