How many calories does biking burn?
A 70 kg person cycling at a moderate pace (19–22 km/h) for one hour burns approximately 588 kcal. At a leisurely pace under 16 km/h, this drops to about 294 kcal per hour. Racing pace cyclists above 25 km/h can burn over 880 kcal per hour.
Calorie burn scales with speed because higher speed requires more power output against air resistance, which increases roughly with the cube of velocity. This calculator uses MET values as a practical proxy for speed-based intensity.
