all kids should have a bike, no matter what the price you pay for it. Personally I say the cheaper the better to begin with. If the've never ridden a Giant/Trek/Gary Fisher or whatever name designer brand you want to throw in there....how will they know if their bike sucks or not? If they enjoy riding, as every kid should, then they can get a better bike next time. If the bike ends up collecting spiders in the garage then you haven't wasted a fortune, because we all know the resale value of bikes is awful.
*this is were, if my dad was still alive, he'd be telling us how he had to go to the scrap heap and find bits to build his own first bike when he was a kid.*
I won a Huffy one time.....it was okay until I bought my Trek 850, then realized what a total piece of shit my Huffy was.
