From Cirque de Demain 2007? A unicycle and bicycle on a round trampoline. They are quite entertaining characters - a charming mismatch just as bizarre as the combination of their apparatuses.
The back drop on the bike has to be the coolest looking move in the act, even though they do much harder skills. I love how he springs back up from it without breaking his rider's pose.
The bike spin and face at 2:30 bring to mind Elvis Mokko!
