I dont commute cause I work for myself and have to drive a truck. But I am diabetic and hate to excercise so after I get home from work, I dont get back into a car. I ride my bicycle everywhere, and ride 6 days a week 14 to 20 miles a day year round. Mostly I ride vintage cruisers, one 5 speed and one single speed. Here are pics. Bicycle riding is not excercise for me it is play. I am 60
