Key Takeaways
- Cycling calorie estimates use MET (Metabolic Equivalent of Task) values from the 2024 Compendium of Physical Activities.[1]
- Speed significantly affects calorie burn: racing at 16-19 mph burns about 3x more than leisure cycling under 10 mph.[2]
- Terrain grade adds substantial effort: cycling up a 7-10% grade increases energy expenditure by approximately 60%.[1]
- Stationary bikes with power meters allow precise tracking: 100 watts corresponds to about 6 MET, while 200+ watts reaches 10+ MET.[1]
- E-bikes with high motor support reduce physical effort significantly, with MET values dropping to around 4.0 compared to 6.8 without assistance.[1]

How the Estimate Works
This calculator uses the standard MET-based formula for estimating energy expenditure during cycling:
MET (Metabolic Equivalent of Task) values come from the 2024 Compendium of Physical Activities, which catalogs energy costs for hundreds of activities based on published research.[1]
For terrain cycling, the calculator applies a multiplier to account for the increased effort of climbing. For stationary bikes with power meters, it uses power-specific MET values that provide more precise estimates than speed-based calculations.
Cycling Types Explained
Road Cycling
Flat road cycling uses speed-based MET values ranging from 4.0 (leisure) to 16.0 (competitive racing). This is the most common cycling type for commuting and recreational rides.
Terrain Cycling
When cycling on hilly routes, the grade significantly increases effort. The calculator applies multipliers from 1.15x (slight incline) to 1.6x (steep incline) to the base MET.
Stationary Bike
Indoor cycling with power meters allows precise tracking. Power in watts directly correlates to MET values, from 3.5 MET at 25-30W to 16.3 MET at 325+ watts.
Mountain Biking
Off-road cycling on trails uses a fixed MET of 8.5 due to the variable terrain and technical demands, regardless of speed.
E-Bike
Electric-assisted cycling varies by support level. High motor support reduces effort to 4.0 MET, light support to 6.0 MET, and no support (motor off) matches regular cycling at 6.8 MET.
Speed and Intensity
Cycling speed has a significant impact on energy expenditure. The relationship is not linear — faster speeds require disproportionately more effort due to air resistance.[3]
The Compendium provides specific MET values for speed ranges:
- Under 10 mph: 4.0 MET (leisure)
- 10-11.9 mph: 6.8 MET (light effort)
- 12-13.9 mph: 8.0 MET (moderate effort)
- 14-15.9 mph: 10.0 MET (vigorous effort)
- 16-19 mph: 12.0 MET (racing)
- Over 20 mph: 16.0 MET (competitive)
When you enter a custom speed, the calculator interpolates between these values to provide a smooth estimate.
Terrain and Grade Impact
Cycling uphill requires significantly more effort than flat terrain. The calculator uses terrain multipliers based on grade percentage:[4]
- Flat (0%): No adjustment — baseline MET
- Slight incline (1-3%): 1.15x multiplier (+15% effort)
- Moderate incline (4-6%): 1.35x multiplier (+35% effort)
- Steep incline (7-10%): 1.6x multiplier (+60% effort)
These multipliers are applied to the base MET value for your speed, accounting for the gravitational work required to climb.
Stationary Bike Power
For stationary bikes with power meters, watts provide a more accurate measure of effort than speed. The Compendium includes specific MET values for different power outputs:[1]
Power-based tracking is particularly useful for:
- Spin classes where resistance varies throughout the workout
- Structured training with specific power targets
- Comparing effort across different bikes and settings
The calculator interpolates between power bands when you enter a specific wattage, providing a smooth progression from low to high intensity.
Body Weight Factor
Body weight directly affects calorie expenditure because larger bodies require more energy to move. The MET formula multiplies by body weight in kilograms:[6]
For example, at moderate cycling intensity (8.0 MET) for 30 minutes:
- 60 kg person: ~240 calories
- 70 kg person: ~280 calories
- 80 kg person: ~320 calories
- 90 kg person: ~360 calories
This linear relationship means a 25% increase in body weight results in approximately 25% more calories expended at the same intensity and duration.
