Mainly to be used on campus. I'm not "that" comfortable with fixed gear bikes (with no free hub) I mean I have ridden in a velodrome and know how one feels but I am concerned about riding one on campus with people walking around. I know many ride fixed gear bikes on the streets. I feel that I might be better off riding a single speed with a free hub rear wheels with brakes, any comments?

Oh btw, I ride mainly ride road bikes.
