Ya know, say what you will, but I can't even do a headstand on the flat non-moving floor. That dude was doing headstands and stunting on the bike. I won't stunt, and don't like stunting on public roads, but I can definitely appreciate this kind of skill. Loved the moves where he was throwing the bike around like at 38 seconds. Crazy stuff.
I saw some guys in Myrtle Beach one time and this guy is an amateur compared to them. The end get-off was:
a front stoppie but as the rear is going up the rider puts the kickstand down. He balances with just enough forward motion to hop over the handle bars and land on his feet while the bike falls backwards, bounces twice and leans over onto the sidestand. Then the 2nd guy comes at a 90* angle and does the same thing except when he goes over the handle bars he goes over the 1st guy's bike too and lands on his feet as his bike settles down from bouncing and leans over onto its kickstand.
The rest of the show required way, way more skillz than the posted dude has.....
