Jumping off of a ramp is terrifying no matter what you're doing it in. It could be a skateboard, scooter, or bike. It's all pretty scary. There's something even more terrifying about jumping with a bike though. You're basically flying through the air with a huge hunk of metal. It's either going to land on you or you're going to land on it. If it starts to drift away from you, that's a whole other set of problems. Sometime tells me this guy is going to get the worst of it. The bike is drifting away from him, yet it still looks like it's going to end up hitting him.
I think this trick is called Superman Gone Wrong, or maybe it's Mega Jump to Neck Break. I don't see it being a big hit at the next year's X games.
