Clumsy kid or does the kid have some "athletic tendencies?" Is the kid nice and sturdy? If yes, then the bike would not be out of the question, IMHO. Though, if the kid likes the Power Wheels better why make 'em ride the bike. Know what I'm saying? But if the kid really likes it (and what kid doesn't, really), and appear to be of a sturdy build, I say go for it.
