Any way to create a gear+chain, like for a bike? I would like to create a LEGO bike. I can imagine how most of it would work, but i'm stuck at the chain.

I need a way for the turning pedals (at one spot) to cause the wheel (in the back) to spin with them. A design like the classic bike chain would be nice, but something else that does the job would also work.

It would be best if a solution uses standard pieces, but i do have a few special pieces.
It looks like LEGO sells chain and sprockets, don't know if you'd have them lying around though.

You could also try using pulleys instead. If you don't have any of the actual pulleys, take the tread off of two wheels and stretch a rubber band across, that should work too.
