Thinking of buying a new bicycle? One of your first choices, and not necessarily an easy one, will be where to shop. It can be a challenge because there are a myriad of stores that carry two-wheelers, from specialty retailers, to giant department stores, to backyard garage operations. Where you buy, however, has everything to do with what you get. You see, bicycles aren't like toasters or suitcases. Bikes are shipped in boxes and they must be assembled and tuned.
