Cycling burns a satisfying number of calories without beating up your joints, which is why it remains a favorite low-impact option for everyone from daily commuters to weekend racers. This biking calories per hour calculator estimates how many calories you burn while riding at a chosen intensity, based on your body weight, riding effort, and session length.
Built on the standard MET method used by exercise physiologists, the tool is simple enough for a casual rider and flexible enough for serious cyclists: choose from six intensity levels, or enter a custom MET if you know your workout's exact value. You'll get an hourly burn rate plus totals for your full ride, 30 minutes, and 15 minutes.

Advanced: custom MET value (optional)
How to Use This Calculator
Start by selecting your weight unit and entering your body weight — the value you use on a typical ride day. Then pick the intensity level that best matches the ride you're planning. Most recreational riders should start with Moderate — 12–14 mph or Light — 10–12 mph. If you already know your exact MET from a fitness device, expand the Advanced section and type it in; your custom value will override the dropdown.
Set the duration to the length of your ride in minutes (60 is the default, which makes the main result your true per-hour rate). Press Calculate to see your hourly burn, session total, and per-15-minute figures. Use Reset to clear everything and start over.
Tip: For gravel or hilly routes, choose Mountain biking — general rather than the flat-road speed descriptors, because climbing and uneven terrain increase the effort required at the same speed.
The Formula Behind the Estimate
This calculator uses the standard MET method from the Compendium of Physical Activities. MET, or metabolic equivalent of task, expresses how many times your resting metabolic rate an activity requires. Resting oxygen consumption is about 3.5 ml of oxygen per kilogram per minute, equal to 1 MET.
The full equation is:
Calories per hour = MET × 3.5 × weight in kg ÷ 200 × 60
The 200 accounts for the fact that roughly 200 ml of oxygen consumed corresponds to 1 kcal of energy expenditure; multiplying by 60 converts the minute-based value into an hourly total. For most people this simplifies to about 1.05 kcal per kg per hour per MET. That's why a heavier rider burns more calories at the same speed: their body does more work to move the same distance. If you'd like to explore the concept further, the Wikipedia article on MET is a clear starting point.
For a separate approach that works from speed and distance rather than intensity labels, try the cycling calories burned calculator on this site.
Worked Examples
Example 1 — Moderate 45-minute ride
A 70 kg rider pedals at 12–14 mph (MET 8.0) for 45 minutes. Hourly burn = 8.0 × 70 × 1.05 = 588 kcal/hr. The 45-minute total = 588 × 45 ÷ 60 = 441 kcal.
Example 2 — Light one-hour hop
A rider weighing 160 lb (72.6 kg) cruises at 10–12 mph (MET 6.8) for 60 minutes. Hourly burn = 6.8 × 72.6 × 1.05 = 518 kcal — nearly identical to the first example's hourly rate despite the lower effort because the rider is slightly heavier.
Notice how both intensity and body weight move the final number. Changing either input by even a few percent changes the estimate by 20–40 kcal per hour, so it pays to be honest about your pace and weight.
Reference MET Values for Biking
These values represent steady-effort cycling on mostly flat terrain; hill climbing and strong headwinds effectively increase the MET.
| Activity Description | Speed / Pace | MET |
|---|---|---|
| Leisurely, casual riding | Under 10 mph | 4.0 |
| Light, easy effort | 10–12 mph | 6.8 |
| Moderate, steady effort | 12–14 mph | 8.0 |
| Vigorous effort | 14–16 mph | 10.0 |
| Very vigorous / racing | Over 16 mph | 12.0 |
| Mountain or BMX riding | General | 8.5 |
Stationary cycling classes often report MET values between 5.5 and 12.5 depending on intensity. If you train indoors, the spin calories at moderate intensity calculator is tuned for studio spin workouts.
Tips for Realistic Estimates
- Weigh yourself without shoes and in light clothing; the weight you enter is the single biggest driver of your per-hour total.
- Use the effort level that matches the majority of your ride. An hour with hills and rests is better described by mountain biking or vigorous MET than by a flat-road average.
- Only count active riding minutes. If you stop for traffic lights, coffee, or photos, those minutes don't add to the total.
- For e-bike rides, reduce the MET by roughly 20–40% because the motor does some of the work.
- Remember this is a gross energy estimate, not net calories above resting metabolism. If a fitness tracker shows a similar number, it's using the same general model.
Frequently Asked Questions
Is cycling a good low-impact exercise for beginners?
Yes. Cycling places far less stress on knees and ankles than running, yet it can still raise your heart rate and build leg strength. Choose low gears, keep your cadence comfortable, and build up your duration gradually.
Why does the calculator need my body weight?
Moving a heavier body requires more energy, so calorie burn scales almost linearly with mass. Two riders on the same route at the same speed can differ by 100+ kcal per hour if their weights differ by 30 kg.
Can I use this for an indoor stationary bike?
Yes, choose the intensity that matches how hard you're working. Indoor cycling without wind resistance is easier for a given speed, so base your selection on perceived exertion rather than the mph numbers.
What about short rides?
For rides of 15 minutes or less, you can still use this tool by setting the duration, or check the 15-minute cycling calories calculator for a quicker estimate.
Are these estimates exact?
No. Individual metabolism, bike efficiency, and terrain all introduce variance. The MET method gives a solid planning number, usually within 15–20% of lab-measured values for steady cycling.
