I'm looking to purchase a bike to mostly ride around town (with the wife), but I don't think that an idea of a budding hobby/transportation alternative warrants dropping $500 at a local bike shop. Since I haven't had much luck on Craigslist (and because I don't know enough about bikes to tell a bike in good shape from one that will need all of its parts replaced), I was thinking about ordering online.
So far, I was looking at one of these two:
I'm about 5'9" and both of these claim that they will fit me. I envision riding probably no more than 10 miles per day, 4 days a week.
Can you help me with a suggestion either between these two, or something in this price range?
