We all overuse the word “crazy.” But these guys, well yeah, they’re crazy… like need help crazy.

If one of these riders slips while another pulls his gas-powered pony up from behind, well, use your imagination. Luckily, these guys are also insanely skilled.

Look ma’, no hands. No brains, either, but plenty of balls.
