My son is being encouraged to join the mountain bike team by his friend. He is 12 and overweight and also not the most coordinated. I'd love for him to get involved for the health and fun aspects but are we setting him up for failure?

He can ride a bike but not really change gears. Right now he just has a cheapy from Walmart though. The school has bikes he can use and I'm willing to buy what he needs if he wants to get into it.
