# Bicycles and their mad skillz

## Main Question or Discussion Point

Alright. So I'm froob and must admit I don't quite understand the bicycle and how it seems to give you more for less, so to say. I figured the shape of a wheel and how the curves stand off from the ground sorta enable gravity to give an extra pull on it. How ever , when I went to look it up it said the wheels acts like a lever. Hmm, So how does a lever work? Couldn't find a very exact reason for that. Somehow the lever and the wheel-lever definitions need to match...

Thanks!

more for less
More what for less what?

Well for like one step may only get you two feet, while going down on the pedal may take you several

This is mainly due to rolling. But assuming no rolling (high friction) the bike would be just a lever: you foot moves less than the tire, but with more force, depending on the gearing.
