Title says it all. Having trouble keeping the chain on the rear sprocket. It just isn't aligned right or something. I'm afraid to ride it without the chain throwing over the handle bars. Anyone have any ideas what it could be ? I did have it on another bike without any issues. Would out to 30+ mph no chain issues at all. I'm looking into new mounting plates an hub sprocket adapting hoping that may fix the issue. But won't be a few weeks before I get to order them. . .
