riserbar bike or drops type bike?
If he isnt really in shape you will want to spend a lil more on a lighter wheelset to make life a bit easier on him. if he doesnt have fun he wont want to ride. Take him to a shop and have him fitted to the bike after you are done, best money you can spend on ANY bike.
