I am looking to purchase a bike in the $300 range for commuting to work. I am 6', 235lbs. I am trying to decide which model would be best suited for me in this price range. I've seen the Bianchi Cortina and Raleigh Detour 3.0 or 3.5. Can anyone recommend either of these bikes? Or do you know of another bike that would sit me? I want brand new, no more than $350. I'm not racing or anything, and will ride 95% on road. I really want something comfortable and reliable.
