This poor guy tumbles down a steep mountain side after his buddies tell him...
Look at the air these kids get off this bike jump.
Yet another motorcyclist who wrecks his bike.
A bunch of bike crashes rolled into one video.
Some chubby kid takes a nice fall on a bicycle
Some chick gets her own foot stuck in the bike spokes and takes a tumble.
Yet another idiot trying a fearsome stunt.
This kid busts his face up after a nasty crash.

This guy doesnt quite make the backflip.
