How Long Do You Have to Ride a Bike to Burn 250 Calories?

According to FitDay, riding a bike burns 300 to 350 calories per half hour. This calculation is based on a rider weighing between 200 and 250 pounds who is traveling at a speed of at least 10 miles per hour.

The amount of calories burned while biking depends on the rider's weight, speed and time spent riding. Increased rider weight translates to an increase in calories burned. If the rider weighs less than 200 pounds, he must ride longer or faster in order to burn 250 calories.

When riding for calorie loss, it is important to keep a swift and steady pace. To achieve greater calorie loss, extend the length of the ride.
