A long time ago I found this deserted BMX bike with no wheels and some other trashed parts. In the past I tried putting on old wheels I had laying around but every time I ride the wheels pop out of place (or at least the rear one does). How do I figure out what wheels to get?

When I originally found the bike I was a kid with no money, and now I'm much older and realize I still have this old frame laying around and would like to do something with it. I think I'm going to turn it into a cheap school bike for getting around at my University campus. Light weight and less likely to be stolen.

The overwhelming majority of BMX bikes use 20" wheels.


..every time I ride the wheels pop out of place What do you mean? does the wheel go sideways in the frame? In that case, look for something called a chain tensioner to help keep the axle in place.

The only other thing I can think of would be badly mangled dropouts, and fixing that would be an entirely different project.
