Now my big man has finally come off his stableizers I'm going to start looking at getting him a new one for Christmas. Now by no means am I a lightweight freak when it comes to bike stuff. But would it be worth spending that little bit more on a lighter weight bike instead of the usual heavy duty steel frame kids bikes that are all over the market. Bike will only be used on flat bike paths. Would a lighter one b beneficial to a child and be worth spending that bit extra ?
