The body will burn approximately 400 to 500 calories during one hour of bike riding, according to About.com. The amount of calories used by the body will depend on the intensity of the bike ride and on the bike rider’s body weight.
Bike riding is an efficient way to burn excess calories, lose body fat and improve cardiovascular health. High intensity bike riding, especially uphill, helps to develop the quadriceps, hamstrings and calf muscles. An advantage of developing muscle is that it increases the body’s metabolic rate. A higher metabolic rate will cause the body to burn more calories than a lower one, even while at rest.
