I just started to plan my first bike trip. I plan on riding a good section of the C & O Canal Towpath in the DC area. I'm looking at bikes and trying to decide what kind would be good for me. I don't think that I really need a front suspension but if it fits in my budget I wouldn't mind it. I'm looking to spend $400 to $550. Any suggestion? And if anyone has been on any of the C & O Canal Towpath let me know what you thought about it. Thanks!
