A stunt rider from Australia named Robbie Maddison recently tested a motorbike with a SURFBOARD down by the wheels, so you can ride it on WATER.  And the YouTube video is pretty incredible. He rides it out into a bay . . . turns back toward the beach . . . and catches a WAVE like he’s surfing.  He told “Surfer Magazine” he legitimately thought he was going to die while he was doing it.
