Hi everyone, I recently got the urge to purchase a bicycle, but I am not sure what I want/need. I haven't had a bike since being a kid and now I am in my 20's. I would like a bike that I can cruise around the neighborhood in, run errands (go to the store, etc.) and take on bike trails/offroad. I see a lot of inexpensive bikes at places like The Sports Authority, WalMart, etc. But something tells me that I should be looking at more expensive bikes ($300-500 range). Can anyone point me in the right direction so I can narrow down my choices?
