A troupe of 19 maniacs on unicycles, running knobby tires and disc brakes, hit the slickrock trails of America's off-road capital: Moab, Utah. Not sure off-roading can even get much more dangerous than this... probably why it's such a riot to watch.

We can enjoy the view without the high likelihood of being impaled or tumbling to our deaths thanks to the magic of GoPro.
