Calories Burned Cycling Calculator
Estimate how many calories you burn cycling, from an easy cruise to a hard spin class. Choose your intensity, weight, and time to see the figure.

Cycling is gentle on the joints yet can burn serious calories when you push the pace. Unlike running, where speed and burn are tightly linked, cycling burn depends heavily on effort against wind and resistance, so intensity is the key input. This calculator uses MET values that span leisurely riding, brisk commuting, racing, and indoor spin.
Why intensity matters more than distance on a bike
On a bike, most of your effort goes into overcoming air resistance, which rises steeply with speed. That means a fast rider works far harder than a slow one, even over the same distance. A leisurely cruise is about 4 MET, moderate riding around 8, and hard racing 12 or more. Doubling your speed can more than double your calorie burn.
This is why the cycling calculator asks for intensity rather than distance. A relaxed 10-mile ride and a hammering 10-mile ride burn very different amounts, unlike walking or running where distance largely sets the total.
Indoor cycling and spin classes
Stationary bikes and spin classes remove wind and terrain, so burn depends on the resistance you set and how hard you pedal. A moderate stationary session is about 7 MET, while a vigorous spin class pushing intervals reaches 8.5 or higher. The machine's own calorie readout is often optimistic, so a MET estimate based on your weight is a useful reality check.
Because spin classes mix hard intervals with recovery, the average intensity across a class is usually lower than the peak, plan your estimate around the overall effort, not the hardest sprint.
Cycling for fat loss and joint-friendly training
Cycling is ideal if running bothers your knees or you are carrying more weight, since it supports your body and spares impact. You can accumulate long, calorie-burning sessions with far less soreness, which makes it easy to ride most days.
As with any exercise, pair riding with a sensible calorie deficit for weight loss. The burn is a helpful bonus, but your diet still drives the deficit.
Frequently Asked Questions
For a 70 kg person, moderate cycling burns roughly 400 to 500 calories per hour, easy riding around 250, and hard racing 700 or more. Enter your weight, intensity, and time above for a personalized estimate.
A vigorous 45-minute spin class burns roughly 400 to 600 calories for most adults, depending on body weight and how hard you push the intervals. The bike's on-screen calorie count tends to run high, so a MET-based estimate is a good sanity check.
Greatly. Because air resistance rises sharply with speed, a fast rider burns far more than a slow one, even over the same distance. That is why this calculator uses intensity rather than distance to estimate burn.
Running burns more per minute at typical effort, but cycling is far easier on the joints and lets you sustain longer sessions comfortably. For many people, hard cycling and running end up similar per hour, and the best choice is the one you will do consistently.
It varies widely with speed and wind, unlike running. A relaxed mile might cost 30 to 40 calories, while a fast, into-the-wind mile can cost far more. Because of this, time and intensity give a better estimate for cycling than distance alone.
Yes, especially if impact is a concern. Its low joint stress lets you ride often and long, building a meaningful weekly calorie burn. Combine it with a modest calorie deficit for steady fat loss.
Note: Cycling-calorie figures are estimates from MET values, your weight, and intensity. Wind, hills, drafting, and bike type change the real number, and outdoor riding varies far more than a stationary bike at a set resistance.
