I just can't keep paying $200 a month for gas to get back and forth to work in my Dodge Ram pick-up. I want to commute daily on a bicycle. My commute is 32 miles round trip. My route is 85% open four-lane divided highway with a nice wide bike path, and 15% single lane rural country roads (quite crowded and dangerous). What is the best type of bicycle for me to buy for my commute? Thanks.
