I agree with going to your LBS try out some bikes out, see what fits you, if its in your budget. Most people will say anything is fine to start. It's not. I bought a cheap Schwinn for my 11 mile commute, but I find riding my single speed mtn that I built is much easier and more fun for my ride. And ask questions. In your area, you'll want something to protect your change of clothes and fenders if you plan to ride in the rain. Make sure the fenders fit.
