So I've been researching like crazy to try to figure out what type bike I'll likely be most happy with. Reading this site has helped, but because I'm hoping to buy used, my options are a bit more limited. I *think* I want something more than a tool around town bike -- something with a bit more speed perhaps? Will be riding mostly paved bike paths. One bike I've got my eye on is a Trek Navigator 2.0. Looks pretty good and I plan to test drive it today, but am concerned that it could be too pokey. I'm in pretty good shape for my age so can handle more than a coaster bike. Is it possible that the Navigator is closer to a hybrid than a comfort? Any other words of wisdom?
