    Hi all,

    New here. I recently bought a used motorized bike from someone on Craigslist. It was super fun to ride the first time, then it kinda went downhill. At first, the left pedal came off. I put it back on, and left it for the night. Then, this morning, I thought to myself, Ill take it out for a test ride. I made sure everything was alright, then set off. I made it about a 1/4 of a mile down the street when I heard a loud noise. I immediatley disengaged the engine, and stopped. Then I turned off the engine, and turned around to see what the noise was. The chain that was driving the motorized part was caught in between the wheel and the large gear. I put it back on, then decided to pedal back home. To top it off the pedal fell off right outside my driveway. I brought it back, took off the chain gaurd, then opened up the clutch, as I heard that the gear inside the clutch can be jammed by the chain. I didn't see any jam, so I put it back together. I left the chain guard off, and tried to start it again. Once again, the chain was stuck. I came here hoping you guys would have some ideas to help me out. Thanks a lot. BTW, I'm 16.:-||

    Sounds like your chain is not tight enough or the sprockets are not aligned, the link below I found in the custom search box near the top of the page. There have been many threads on chain problems so you should find a answer. And welcome to the forum, this is the right place to find out how to do just about anything to a m/b.

    You have already learned one thing, use loctite on anything like mounting bolts, pedals and so forth. Vibration from the engine can and will loosen things up. In picture #8 it looks like the sprockets are not aligned, look from the back at the chain it should go off the rear sprocket in a straight line to the engine sprocket.

    Hi Shabhy, welcome to the forum. Everyone I know who is running a steel sprocket on a rag joint has problems with the chain and spokes. One of the easiest and best updates you can do to your bike is to dump the rag joint and install an adaptor. The adaptor requires a 36h rim and a 4 cross spoke pattern. Also keep a close eye on your chain tensioner. If not properly aliened and secured in place it will cause you a world of grief.
    Anything I can do to help.
