I went to Cirque du Soleil this past weekend at Disney World. One of the acts was an acrobat on a bike jumping around all over the place, climbing stairs and stuff. He took an audience member and made him lie down on the ground, then rode up to him, stoppped, then bunny hopped and landed so that the dude was in between his wheels. It was sweet
Anyway, another part was where he was on a platform with no where to move and he track stood for a minute or so. The bike wasn't even fixed gear. It was so sweet.
