The best explanation is demonstrated in the old B. Kliban cartoon (featured in either "Cat" or in "Never Eat Anything Bigger Than Your Head") showing how the anti-jump muscles work.� Contracted, they keep you on the ground.� Relaxed, you just float away.

The skills of the guy on the bike are nothing short of amazing!
But I've never understood the physics of how he can jump the bike like that without pushing off the ground with his feet. �Same thing with skateboarders who do similar tricks.
Since it is Frydae, perhaps one of the list resident geniuses could explain it.
