Fat Bike Commuters I have a special distaste reserved for bike commuters who are fatasses. Yes biking is "low impact" and isn't a super calorie burner, but it is still exercise. If you commute via bike for work, you are essentially getting a built-in cardio sesh every day. Why are you still fat? I was lucky enough to be able to bike to work for a few years and it helped my physique a lot.  People I personally know who bike commute are also in good shape and are not fatasses. I don't understand. Why, fats?
