Cool invention to practice your bmx bike tricks!
That kid has got some balls on him!
He took the corner a little to fast.
This is one hard fall. This kid falls down a flight of steps!
Honestly the guy on the motorcycle never even had a chance. WOW!
Huge bike jump. Will he make it?
Wow, that was quite an impressive trick...lol
Those guys in Nitro Circus are nuts!
