Here are a bunch of clips of people crashing hard on Bikes.
This guy reeks of douchebaggyness. That's what you get for showing off in...
He attempts the first ever triple backflip on a BMX bike and nails it!!!
Freestyle Motocross Landing Fail, That's going to leave a mark.
Now that's how you load a dirt bike into a pickup truck!
Some more bike stunts and bad crashes.
Not only does he botch the stunt but the dirt bike smashes him in the head.
