Way cool!

He saves his balls by not having a saddle or seat post on that bike; good thing too.

I saw a young doing stunts like that, well not quite that extreme, but many of the same basic moves. He was sponsored by the Seattle to Portland bike ride, and I was watching him in the finish line park after riding 206 miles, and was fascinated as he'd jump up on a picnic table, then into a tree, etc. I wondered how he could generate so much bounce from a standing start and saw that he had his tires less than half fully inflated. That's how they get so much bounce, and also cushions those extreme drops. Still, way skilled and way crazy. At least he was wearing a crash helmet.
