This is what I am doing. I commute 18 miles one way. I am currently using my "comfort bike". I am not sure if I am just going to upgrade my bike. Or just buy a new bike yet. Been doing it for two weeks now. Still undecided.
I would do like pinkrobe said, give it a shot once or twice and see how it goes.
