A few months ago i had a bad crash on my bmx and ever since that crash its had problems i fixed most problems, but there one that im not sure about, when i go fast on the bmx the chain comes off, and it hurts your knee's :D smashing them into the handle bars. Anyone know what the problem is and how i could fix or replace it?

    It's not just that the back wheel has moved slightly making the chain loose? If so undo the bolts and then pull the wheel back so the chain is tight then retighten the bolts

    or the frame is bent.

    then take a link out?

    but it does sound like the frame could be damaged. get it checked out.
