The number of calories burned while biking varies widely depending on factors such as intensity, speed, duration, body weight, and terrain.

• General estimates:
  • Leisure or easy cycling (commuting, light effort) burns about 300 calories per hour.
  • Moderate cycling can burn around 600 calories per hour.
  • Strenuous cycling or racing can burn 1,000 calories per hour or more

• By speed and intensity for a person weighing around 175 lbs (79 kg):
  • Leisurely pace (below 10 mph): approximately 337 calories per 30 minutes, or about 674 calories per hour.
  • Moderate pace (12-14 mph): around 400 calories per hour.
  • Vigorous pace (16 mph or higher): up to 530 calories or more per hour

• Calories burned per hour by weight and speed (approximate):

Weight (lbs)| 10 mph (leisure)| 12 mph (moderate)| 16 mph (vigorous)
---|---|---|---
150| 286| 343| 458
175| 333| 400| 533
200| 381| 457| 608

• Other factors:
  • Stationary biking generally burns fewer calories than road biking at the same intensity (about 10-12.5% less).
  • Using power output or heart rate can provide more precise calorie estimates.
  • MET (Metabolic Equivalent of Task) values for biking range from 4 for leisure cycling to 16 for racing, influencing calorie burn calculations

In summary, biking can burn anywhere from about 300 calories per hour at an easy pace to over 1,000 calories per hour at very high intensity, with typical moderate cycling burning around 400-650 calories per hour depending on individual factors.
