I need to buy my son a bike for the summer. He's too big for his old, 20 incher, so I've been looking around at the 24" models - the next and last step before the full adult 26". I'm finding a few fairly well put together bikes for about $250, and then the Mongoose/Huffy WalMart variety for anywhere from $90 to $200. Most places just have nothing. I'm seaching for something of a happy medium, since this is more for transport than it is because he's "way into biking." Unfortunately, he's not, at least not yet. I lucked into an old 26" specialized mtb (7-speed, so you know its old) that my sister in law had, she never rides, and is in perfect shape. I tried to get him to ride it, but he said it was too big. Should I just get him a cheap 26" anyway, or keep searching for a 24" bike that will either cost too much or break too soon? Anyone ever deal with the same problem?
