Hello, I'm a 61 year old male in Minneapolis thinking of getting a bike. I haven't been on one for over 35 years. Might get me back in good shape and help me loose the extra 50lb. I'm carrying around. I am 6'3" and around 230lb. I Stopped into a couple of bike shops today and looked at a Trek 7100, a couple of Specialized comfort models and a Cannondale (too expensive). At this point I have to rely on the sales people and of course each one says the one they are selling is the best. Any advice is surely welcome.
