Watch this guy surf ocean waves while riding a dirt bike

DC Shoes has sponsored a beautiful Frankenstein of extreme sports: a dirt bike that can surf ocean waves.

The project took two and a half years of testing and building to get to the point where Australian stuntman Robbie Maddison could ride the waves, according to a behind-the-scenes video first discovered by The Verge. But the end product is quite astounding.

In the four-minute video above, Maddison tears up the water of Tahiti, looking impossibly "in control."
