Since I've been riding, my 12 year old nephew has become interested in bikes. He doesn't know how to ride a bike, and I am dying to rectify that fact. I am even willing to purchase a bike for him so he can learn. I don't have a lot of money to spend, and of course, he'll eventually outgrow the bike, so I'd hate to invest a lot, but I'd like him to have a nice starter bike.
I am thinking of a good used bike on CL. He's about 4'11" with a 25-26" inseam. Is he tall enough for a small adult's bike, or should I look at kid's bikes? I don't have kids of my own, otherwise, I might know more!
