How do I remove the sprocket off of a one piece crank of an old BMX bike?

Question

I have a really old bike, no gears or anything just the front and back sprockets. I have the one piece crank out, but i cant remove the chain wheel. there aren't any nuts to unscrew.

Answer 1

This question is a very difficult one to answer. One must be there looking at the bike to help. One piece cranks are a pain, it is very difficult to change/remove sprockets. My suggestion: if you don't know EXACTLY how to do it yourself already, take it to your local bike shop!

Answer 2

Check http://brandscycle.com  for bicycle tools,but if you are good

a bicycle shop will do it for free. Good lock

Answer 3

Usually the sprockets are riveted to the crank.  Check with the link below.  I'm not sure what you are trying to do, replace the whole thing, upgrade or change the sprocket.
