My son learned how to ride a bike with out training wheels just after he turned 4. He got his first pair of roller blades at 5. I would not be surprised if I saw him in the X games when he is older. However, it still makes me cringe when I see videos like this one. This rider is amazing at what he does. It wasn't until half way through that I was brave enough to watch with both eyes open. So enjoy, and one day this might by my son.
