In short, no. You'll find little to no difference between women's fixed gear bikes and men's fixed gear bikes other than a smaller frame size to accommodate shorter riders. Some also have a shorter reach between the seat and the handlebars, too, so shorter cyclists don't need to stretch uncomfortably to reach them. Of course, women can be short and men can be tall, so a "women's" bike might be a better fit for a short man and a "men's" bike might be a better fit for a tall woman. In the past, women's bikes had a sloped top tube because this was easier to ride when wearing long skirts, but most women's fixed gear bikes have a straight top tube.;
