Robbie Madison is at it again. Not content with backflipping over London's Tower Bridge, the MTX mentalist took his bike to the Olympic ski jump at Park City, USA.

Reaching over 70mph as he hit the edge of the gargantuan jump, he flew for 374feet. That's longer than the length of a football field.Oh, and there's the little matter of the drop.

From lip-to-landing, Madison dropped a bone-jaring 185 feet - over 18 stories. Just imagine that for a second. Next time you see an 18 story building, imagine dropping off the roof, on a bike. Gnarly.
