In addition, the driving time may be provided with a time counting unit in the acceleration sensor 20, or separately provided with a time counting unit to count the driving time. Of course, the driving time information will be necessary to derive the driving speed and the driving distance. And calorie consumption can be derived by the following equation (1).

Calorie consumption (cal) = 0.0175 × METS × Weight (kg) × 1000

METS is the value according to the database of Metabolic Equivalents. For example, the METS is 14 when riding at 25 to 30 km / sec. In addition, the weight may obtain the user's weight by the pressure sensor 30, or may be obtained by the user's input.

4 is a screen displaying a graph showing a change in calorie consumption for 8 days. Referring to FIG. 4, a graph showing a change in calories consumed by riding a bicycle every day from March 24 to March 31 is displayed on the screen of the terminal 200. By checking the change in calorie consumption, the user can adjust the amount of exercise using the bicycle, and effectively use the bicycle as an exercise.
