This one will make you wince.
In the video, we hear his team mate, Travis Walker, warning van der Spuy to "watch the buck." And while van der Spuy looks to his right, there's nothing he can do. Moments later...well, you'll see what happens.
Shockingly, the visibly shaken -- and audibly groaning -- van der Spuy didn't suffer any serious injuries, although his helmet was shattered. He tweeted later that he's "stable with nothing more than a very stiff neck," thanking his team mates for their help.
According to the YouTube description, Walker took this video with a GoPro camera. GoPro has been suspected of launching some pretty savvy viral video campaigns, but this video seems legit.
