It's so cool to have a dad that's able to get you into the sport when you're that young. Some of the best rides I've ever had was with my dad at that age, not caring about what other people were doing or how fast you were going...just riding and having a good time. Don't force him into anything but encourage him to stick with it. You can go real far when you have that kind of support early in life.
