I'm toying with the idea of buying a bike. I can get most places I want by walking/public transportation, and I have a car, but I wouldn't mind having an alternate form of transportation handy. I am not in the market for high end, here. This is for riding around the neighborhood/to bars/to shows/maybe occasionally to work (about 5 miles, accessible on residential streets, for the most part), not for putting on a postal service uni and clipping in. Also, bikes get stolen around here pretty regularly, so flashy and new is not good. On the other hand, it's pretty hilly around here, so some functionality would be nice. Any recommendations? I've flipped through craigslist for a few days, assessing what's out there. Seems like, in the <$200 range, there's a lot of older road bikes and a few 90s model mountain bikes. What do you guys ride?
