I found this bike on Craigslist for $175. I am thinking about buying it to commute to and from light rail stations in Baltimore for work. It won't be more than a one mile commute at either end of the rail ride. I like it for its light frame and mustache handlebars that allow me to sit upright or lean forward. Is a three speed acceptable for a commute as short as mine? The route from the light rail to work is a slight incline (you can see it if you search "railroad ave, Baltimore" and head north on Fall Rd using street view). I'm a little concerned about not being able to change gears while pedaling, but I could get used to it. Besides commuting, I'll use my bike to get around the city. Thanks for your help!
