I'm looking for people who want to be rid of their kids sized road bikes because their kids outgrew them or no longer need them. I can get a new fuji (about a 39cm frame?) w/ 650 wheels new for about $500, but I have 6 kids to fit and would rather buy used equipment to save some $. Any small bikes out there? I suppose a compact geometry bike could work too, but I'm thinking those are probably too pricey since they are a newer design generally.
