I'm 47 and just moved to a nice flat area. I rode the standard 10 speed 27" when I was 16. I'm looking for a good bicycle to ride around the nice flat areas of my developement. Who knows, maybe I'll start making the 15 mile trek everyday to work on nice paved flat roads. I'm in med to ok condition, certainly closer to the med condition. 180 pounds, not very athletic, not a lot of muscle built up. What do I want to get? Price is really not a big object although obviously I'd rather spend money on audio rather than a bike. $300 to $700 is certainly not a concern. I'm thinking super lightweight though. What do I want to look at???
