In the first place, there’s street biking, which isn’t all that safe to begin with. Then there’s offroad biking, which makes up for a lack of careless motorists with countless natural dangers. Finally, you have the sort of extreme biking that entails using the side of a mountain as a customized obstacle course—a radical stunt you can experience for yourself via GoPro camera.

It’s all a bit dizzying and bone-rattling, but don’t feel bad: even the cyclist has to pause once to collect himself, later emitting a worried “Whoa!” when he comes off a particularly diabolical ramp.

Public service announcement to would-be daredevils: it may feel, after watching that, as if you can execute a mid-air 360º spin over treacherous rocks on a mountain bike. But no, you can’t.
