I saw Justin Case over the summer with the Big Apple Circus- he has similar skills (actually, she appears to be slightly more talented on the balance end of things) but also disassembled and reassembled his bike in all these crazy ways and rode it, while keeping up a running commentary. I have been trying to explain what he did to DH, who wasn't there to see it- this video will help! I have been watching a lot of freestyle mountain bike stuff lately, too- all so cool and inspiring!
