Have you ever wondered how many calories you burn when you ride? Use my calculator to find out. Simply select your average speed and then enter your body weight. This will give you the number of calories you burn per minute at the given speed. Remember though, riding up hill will increase the amount of calories burned, and coasting down hill will decrease the amount burned. If you want to calculate the calories lost for a ride enter the time in minutes that you rode along with the other values.
