Right now I only have one bicycle, an 87 Schwinn Tempo. It's a racing bike, and that's what I intend to use it for (once I get in better shape) but I've been using it to commute as well, and it's not exactly suited for it. I'd like to get an inexpensive (<$600 USD) commuter that preferably comes equipped with a back rack and fenders already on, and a more upright posture. I'd use it mainly for my 3 mile commute (flat terrain) and sometimes going to the grocery store (3 miles, again flat terrain.)
Something like the Jamis Commuter series, or maybe Trek Bellevue. Does anyone have any recommendations/bad experiences with bikes in this category? Stuff I should look out for?
