Cycling is one of the most enjoyable ways to stay active, whether you're commuting, exploring trails, or training for a long ride. But how many calories do you actually burn per hour? The answer depends on your weight, your speed, the terrain, and even the type of bike you ride. This calculator gives you a realistic estimate based on the widely used MET (Metabolic Equivalent of Task) values from the Compendium of Physical Activities.
Simply enter your weight, choose your riding speed and terrain, and pick your bike type. The tool instantly shows your calories burned per hour, plus a breakdown of the math behind the estimate. It's perfect for anyone planning a ride, tracking fitness goals, or just curious about the energy cost of their favorite route. Whether you're a casual cruiser or a weekend racer, this gentle-movement calculator helps you understand your effort at a glance.
🚴♂️ Bicycle Calories Per Hour
How to Use This Tool
Start by entering your body weight and choosing the unit (kg or lb). Then enter your typical riding speed and select whether it's in km/h or mph. Choose the terrain you'll be riding on — road, gravel, or mountain — and the type of bike you use, since an e-bike with pedal assist burns fewer calories than a road bike at the same speed. Click Calculate to see your estimated calories burned per hour, along with the MET value used and a breakdown of the formula. Use the quick-fill buttons to load common values, and the reset button to clear everything.
How It Works
This calculator uses the MET (Metabolic Equivalent of Task) method, which is the standard approach in exercise science for estimating energy expenditure. One MET is the energy cost of sitting quietly, roughly 1 kcal per kilogram of body weight per hour. When you exercise, your body works harder, and the MET value reflects how many times harder than rest the activity is.
The formula is simple: Calories per hour = MET × weight (kg) × 1.05. The 1.05 factor accounts for the fact that the standard MET definition is based on oxygen consumption, and the actual energy expenditure is slightly higher than the theoretical value. The MET values used here are based on the Compendium of Physical Activities, a widely cited research resource maintained by Arizona State University and the National Institutes of Health.
For example, cycling at a moderate pace of 20 km/h on a road bike has a MET value of about 6.5. A 70 kg person would burn roughly 6.5 × 70 × 1.05 = 478 kcal per hour. The calculator adjusts the MET value based on your speed, terrain, and bike type to give a more personalized estimate.
Worked Examples
Example 1: A 70 kg rider on a road bike, riding at 20 km/h on flat pavement. MET = 6.5. Calories per hour = 6.5 × 70 × 1.05 = 478 kcal. That's about 8 kcal per minute.
Example 2: A 155 lb (70.3 kg) rider on a mountain bike, riding at 15 km/h on a gravel trail. First convert weight to kg: 155 × 0.4536 = 70.3 kg. MET for mountain bike on gravel at moderate speed is about 6.5. Calories per hour = 6.5 × 70.3 × 1.05 = 480 kcal.
Example 3: A 60 kg rider on an e-bike with pedal assist, riding at 25 km/h on a road. MET = 4.0 (e-bikes are less demanding). Calories per hour = 4.0 × 60 × 1.05 = 252 kcal. Notice how much lower this is than a regular bike at the same speed.
Factors Affecting Accuracy
Several factors can make your actual calorie burn differ from the estimate. Your fitness level plays a role — a trained cyclist may burn fewer calories at the same speed because their body is more efficient. Wind resistance, hills, and road surface all increase effort, and the calculator's terrain adjustment tries to capture some of that. Your bike's weight and tire pressure also matter, as do your posture and how much you're carrying. The MET values are averages from research studies, so individual variation is normal. For the most accurate tracking, consider using a heart rate monitor or a power meter, which measure your actual physiological response.
Tips & Best Practices
- Use your actual body weight, not an ideal weight, for the most accurate estimate.
- If you ride on rolling hills, choose the gravel or mountain terrain option to account for the extra effort.
- For interval training, where you alternate between fast and slow segments, the average speed may underestimate your calorie burn — consider using a higher speed or a dedicated interval calculator.
- Remember that calorie estimates are just that — estimates. Use them as a general guide for planning nutrition and tracking trends over time.
Frequently Asked Questions
How many calories do I burn cycling for an hour?
It depends on your weight, speed, and terrain. A 70 kg person cycling at a moderate 20 km/h on a road bike burns about 478 kcal per hour. Heavier riders burn more, and faster speeds or rougher terrain increase the burn.
Does cycling burn belly fat?
Cycling burns calories, which helps create the calorie deficit needed for fat loss. However, you can't spot-reduce fat — your body decides where it loses fat from. Consistent cycling combined with a balanced diet is an effective way to reduce overall body fat.
Is cycling good for weight loss?
Yes, cycling is an excellent low-impact exercise that can burn a significant number of calories. It's easy on the joints, making it suitable for people of all fitness levels. To lose weight, aim for a calorie deficit of about 500 kcal per day through a combination of diet and exercise.
How does an e-bike compare to a regular bike?
E-bikes with pedal assist require less physical effort, so you burn fewer calories at the same speed. However, they still provide moderate exercise, especially if you use lower assist levels. The calculator uses a MET of 4.0 for e-bikes, compared to 5.5–8.5 for regular bikes depending on conditions.
