I ride my two Jamis (see signature) bikes everyday that I can. I ride to work 5 - 7 days a week on my comfort style Jamis and then I ride my other Jamis for my workouts or to go longer distances. I only bought the comfort bike to ride with my wife, but it is easy enough to ride the really short distance to the YMCA everyday to work.
