That wasn't a bad fall at all. If you check it out, he didnt exactly bounce off the roof....he just didnt get his rear tire (or most of the bike) onto the roof, which caused him to drop. The bike is probably in need of a repair (a 20 ft drop will do that) but I'll bet the guy was fine. Did you see the size of that ramp though?? If it was a little longer, or a little closer to the house, he woulda pulled it off...but then he probably would have just fallen off the other side of the house!
