My wife & I have decided to get back in to bicycling for fun and much needed exercise. For her b-day I just bought her a Jamis explorer 2 due to arrive this week. I'm not sure what I want for myself. I've been looking at four different bikes: Jamis explorer 3.0, Specialized expedition elite, Giant sedona dx and Trek navigator 3.0. I am hoping for someone's input to help me decide. We're really looking forward to to cycling again while the weather here is still nice.
