My thought is that something like this could help me get back
into shape. I want to be able to ride my bike to work, and while I'm trying to build my way up to that level of endurance, I'm beginning to wonder if I'm going to make it before oil prices make it impossible to get there any other way. (It's only 7 miles, but that's if you measure flat distance. It's quite a bit longer than that if you take the hills into account!
