I can't believe some people can be so shallow. I am 5'4", 187 lbs., and I ride with friends. We are all different shapes and sizes and we average 30-50 mile bike rides 3 x's per week. We are able to keep an average of 18-20 miles per hour. I am by far the "biggest" woman in the group, but have never received any negative comments about my size. When it comes to riding, you should be with people that appreciate the ride, and mostly appreciate you. It is not about looks or size, but about having fun. Shame to that woman that gave you a hard time!
