Calories Burned Cycling Per Hour 2026
Quick Take
A 150-pound person burns 250-600 calories per hour cycling, depending on speed and intensity. Casual cycling (10-12 mph) averages 250-300 calories, while vigorous road cycling (16-19 mph) reaches 500-600 calories per hour. Use the Exercise Calorie Calculator for personalized results.
Cycling is one of the most efficient cardiovascular exercises for calorie burn, offering a unique combination of high energy expenditure and low joint impact. Whether you ride a road bike through the countryside, navigate mountain trails, or crush intervals on a stationary bike, understanding the calorie burn data helps you set realistic fitness goals and track progress.
This 2026 guide covers the latest MET-based cycling calorie data, breaks down the numbers by speed and weight, compares road cycling to mountain biking and indoor cycling, and shows how to use cycling for effective weight loss. For instant personalized calculations, use the Exercise Calorie Calculator with your weight and cycling speed.
The MET Formula for Cycling
Scientists use Metabolic Equivalents of Task (METs) to measure cycling energy expenditure. One MET equals the energy burned at rest — about 1 calorie per kilogram of body weight per hour. The 2026 Compendium of Physical Activities provides the most accurate MET values for cycling, derived from laboratory testing using indirect calorimetry.
The calorie formula for cycling is:
Calories burned cycling = MET value × body weight in kg × time in hours
Cycling MET Values by Type and Speed (2026 Compendium)
| Cycling Type | Speed / Intensity | MET Value | Calories per Hour (150 lb) |
|---|---|---|---|
| Stationary, Light | 50-90 W | 4.8 | ~305 |
| Stationary, Moderate | 100-125 W | 6.8 | ~432 |
| Stationary, Vigorous | 150-175 W | 8.0 | ~508 |
| Road Cycling, Casual | 10-12 mph | 4.8 | ~305 |
| Road Cycling, Moderate | 14-16 mph | 6.8 | ~432 |
| Road Cycling, Vigorous | 17-19 mph | 8.0 | ~508 |
| Mountain Biking | Off-road, moderate | 8.0 | ~508 |
These values represent gross calorie expenditure — including the calories your body would have burned at rest. Net calorie burn (above resting metabolic rate) is typically 70-80% of gross values, depending on intensity and fitness level.
Calories Burned Cycling Per Hour by Weight
Body weight is the primary determinant of cycling calorie burn. Heavier cyclists burn more calories because they are moving more mass. Here is the breakdown for three common cycling intensities:
| Body Weight | Casual (12 mph) | Moderate (15 mph) | Vigorous (18 mph) |
|---|---|---|---|
| 120 lb (54.4 kg) | ~245 | ~345 | ~406 |
| 150 lb (68.0 kg) | ~305 | ~432 | ~508 |
| 180 lb (81.6 kg) | ~366 | ~518 | ~610 |
| 210 lb (95.3 kg) | ~427 | ~605 | ~713 |
| 250 lb (113.4 kg) | ~509 | ~722 | ~843 |
The calorie burn scales linearly with body weight. A 250-pound cyclist burns roughly 1.66 times more calories per hour than a 150-pound cyclist at the same intensity. This is consistent across all cycling types and speeds.
Road Cycling vs Mountain Biking vs Indoor Cycling
Not all cycling is created equal. The type of cycling you choose dramatically affects calorie burn through differences in terrain resistance, bike efficiency, and rider position.
Road Cycling
Road bikes are designed for efficiency on paved surfaces. At moderate speeds (14-16 mph), road cycling burns 400-450 calories per hour for a 150-pound person. Cycling on flat terrain is more energy-efficient than climbing hills — each 1% grade increase adds approximately 10-12% to calorie burn. A 2025 study in International Journal of Sports Physiology and Performance found that road cyclists burn 15-20% more calories per hour on rolling terrain compared to flat courses at the same average speed.
Mountain Biking
Mountain biking consistently burns the most calories among cycling disciplines due to variable terrain, trail obstacles, and the need for constant adjustments. Even at a leisurely pace, mountain biking typically matches or exceeds vigorous road cycling calorie expenditure. Technical trails with frequent elevation changes and obstacles can push calorie burn to 600-800 calories per hour for a 150-pound rider, according to the 2026 Compendium update.
Indoor Cycling (Stationary Bike)
Stationary bikes provide a controlled environment for calorie burn. The MET values for indoor cycling closely match road cycling at equivalent power outputs. However, a 2024 study in Journal of Strength and Conditioning Research found that most people overestimate their cycling intensity on stationary bikes, typically reporting "vigorous" effort when they are actually producing only 60-70% of the power associated with that intensity level.
Spin Class / Indoor Cycling Class
Structured indoor cycling classes typically alternate between seated and standing positions, with varying resistance levels. A 45-minute spin class burns 300-500 calories for a 150-pound person, depending on intensity. The group dynamic and music often motivate participants to maintain higher average power output than they would on a solo ride.
Cycling for Weight Loss: Realistic Projections
One pound of fat represents approximately 3,500 calories of stored energy. Here is how different weekly cycling volumes translate to fat loss for a 150-pound cyclist:
| Weekly Cycling Volume | Weekly Calorie Burn | Weekly Fat Loss (No Diet Change) | Weekly Fat Loss (300 kcal Diet Cut) |
|---|---|---|---|
| 3 hours (casual) | ~915 | ~0.26 lb | ~0.86 lb |
| 3 hours (moderate) | ~1,296 | ~0.37 lb | ~0.97 lb |
| 5 hours (moderate) | ~2,160 | ~0.62 lb | ~1.22 lb |
| 5 hours (vigorous) | ~2,540 | ~0.73 lb | ~1.33 lb |
| 7 hours (vigorous) | ~3,556 | ~1.02 lb | ~1.62 lb |
These projections reveal an important pattern: cycling alone produces modest weekly fat loss. The combination of cycling with a modest dietary deficit (300 calories per day, roughly equivalent to eliminating one sweetened beverage) nearly doubles the fat-loss rate. The Calorie Deficit Calculator allows you to model different cycling and diet scenarios to find a sustainable plan.
Cycling Intensity and Heart Rate Zones
Heart rate zones provide a practical way to gauge cycling intensity and ensure you are hitting your calorie-burn targets. The five standard zones based on maximum heart rate (estimated as 220 minus your age):
| Zone | Heart Rate (% of Max) | Perceived Effort | Calorie Burn (150 lb) |
|---|---|---|---|
| Zone 1 (Recovery) | 50-60% | Very easy, can hold a conversation | ~245/hr |
| Zone 2 (Endurance) | 60-70% | Comfortable, slightly breathless | ~370/hr |
| Zone 3 (Tempo) | 70-80% | Moderate, can speak short phrases | ~465/hr |
| Zone 4 (Threshold) | 80-90% | Hard, can only say a few words | ~555/hr |
| Zone 5 (Maximum) | 90-100% | All-out, cannot speak | ~650/hr |
For fat loss, most cycling volume should target Zones 2-3, where the body burns a higher proportion of fat as fuel. Higher zones burn more total calories but rely more on glycogen stores.
Can Cycling Replace Other Cardio for Weight Loss?
Cycling offers several advantages over running and other cardio modalities: lower joint impact, ability to maintain higher intensity for longer durations, and easy adjustment of intensity through gear selection or resistance changes. A 2023 study in Medicine & Science in Sports & Exercise found that cycling and running produce nearly identical fat-loss results when matched for total calorie expenditure — but cycling adherence rates are 30% higher among adults with joint pain or who find running too intense.
