How Many Calories Does Cycling Burn? Exact Numbers by Speed and Weight

This article is for educational purposes only and is not medical advice. Talk with a qualified healthcare professional before making major nutrition, weight loss, or medication-related changes.

Cycling burns roughly 400 to 1,000 calories per hour, or about 7 to 16 calories per minute, for most adults. A 150-pound person burns around 545 calories per hour at a moderate 12 to 14 mph pace, while a 200-pound person riding hard at 16 to 19 mph can top 1,000.

The problem is that Peloton screens, gym bike consoles, and generic charts often disagree by 200 calories or more for the same ride. Below are the precise numbers from the Compendium of Physical Activities (the MET database used by exercise physiologists), broken down by weight and speed, so you can stop guessing.

Key Takeaways

Body weight and intensity are the two biggest factors. A 200-lb rider burns about 65% more than a 120-lb rider at the same speed
A 30-minute moderate ride (12-14 mph) burns about 273 calories at 150 lb and 364 calories at 200 lb
A spin or Peloton class burns roughly 400 to 600 calories in 45 minutes at a vigorous effort
Indoor bike consoles overestimate calorie burn, often by 15 to 30 percent, because they assume a generic weight and drivetrain efficiency
Cycling is non-weight-bearing, so it burns fewer calories than running at the same perceived effort, but it is far gentler on the joints
To burn 500 calories, most people need 40 to 70 minutes of steady moderate cycling

What is a MET, and how are cycling calories calculated?

A MET (Metabolic Equivalent of Task) is a measure of how much energy an activity uses compared to sitting still. One MET is the energy you burn at rest. Cycling ranges from about 4 METs (a leisurely roll under 10 mph) up to 16 METs (racing above 20 mph).

The formula is: Calories per hour = MET value × body weight in kilograms. To convert pounds to kilograms, divide by 2.2. So a 150-pound rider at a moderate 12 to 14 mph pace (8.0 METs) burns about 8.0 × 68 = 545 calories per hour, or roughly 9 calories per minute.

How many calories does cycling burn per minute by weight and speed?

Here are the calorie burn rates per minute at common cycling speeds, using MET values from the 2024 Adult Compendium of Physical Activities:

Speed (effort)	120 lb	150 lb	180 lb	200 lb
<10 mph (leisurely)	3.6	4.5	5.5	6.1
10-12 mph (light)	6.2	7.7	9.3	10.3
12-14 mph (moderate)	7.3	9.1	10.9	12.1
14-16 mph (vigorous)	9.1	11.4	13.6	15.2
16-19 mph (racing)	10.9	13.6	16.4	18.2

Calories per minute. Multiply by ride duration for total burn. Multiply by 60 for calories per hour.

How many calories does a 30-minute bike ride burn?

A 30-minute ride at a moderate 12 to 14 mph pace burns approximately:

120 lb: 218 calories
150 lb: 273 calories
180 lb: 327 calories
200 lb: 364 calories

Push the pace to a vigorous 14 to 16 mph and those numbers rise to about 273, 341, 409, and 455 calories. Drop to a leisurely sub-10 mph cruise and they fall to roughly 108, 135, 164, and 182 calories for the same weights. Intensity changes your burn far more than duration alone.

Does a stationary bike, spin class, or Peloton burn more calories?

It comes down to effort, not the type of bike. A spin or Peloton class is listed at about 8.5 to 9.0 METs in the Compendium, which is the same vigorous zone as riding 14 to 16 mph outdoors. A typical 45-minute spin class burns 400 to 600 calories for most adults at a moderate-to-hard effort.

Outdoor cycling can burn slightly more at a matched intensity because of wind resistance, hills, and the constant micro-adjustments needed for balance. According to Harvard Health, a 155-pound person burns about 252 calories in 30 minutes of moderate stationary cycling versus roughly 288 calories outdoors at 12 to 14 mph. The gap is real but small. A hard indoor session beats an easy outdoor cruise every time.

Why your Peloton or gym bike overestimates your calorie burn

Indoor bike consoles are optimistic. They typically assume a generic rider weight, estimate power from cadence and resistance rather than measuring it directly, and ignore your individual efficiency. The result: most bike displays overstate calories by 15 to 30 percent.

Wearables are not much better. A 2017 Stanford study tested seven popular fitness trackers (Apple Watch, Fitbit, Garmin, and others) against gold-standard indirect calorimetry and found energy expenditure readings were off by an average of 27 percent, with some devices missing by as much as 93 percent. If your screen says you burned 700 calories, the real number is probably closer to 500.

This matters most if you are eating back exercise calories. Over-reporting your burn leads to over-eating, which quietly erases the deficit your ride created.

Is cycling good for weight loss, and does it burn belly fat?

Yes, cycling is an effective and joint-friendly way to create the calorie deficit that drives fat loss. A systematic review in Scandinavian Journal of Medicine & Science in Sports found regular cycling is associated with meaningful improvements in body composition and cardiovascular fitness.

You cannot spot-reduce belly fat with cycling or any other exercise. But a sustained calorie deficit does preferentially burn visceral (deep belly) fat first, because it is the most metabolically active fat tissue. To maximize fat loss, most guidance points to 150 or more minutes of moderate cycling per week, with a couple of higher-intensity interval sessions mixed in.

Here is the catch: cycling creates the deficit, but your diet decides whether it turns into fat loss. A 30-minute ride that burns 300 calories is fully undone by a single post-ride smoothie. For a full breakdown of your maintenance number, see our guide to calculating your TDEE.

How long do I need to cycle to burn 500 calories?

At a moderate 12 to 14 mph pace, hitting 500 calories takes between 40 and 70 minutes depending on your weight:

120 lb rider: about 68 minutes
150 lb rider: about 55 minutes
180 lb rider: about 46 minutes
200 lb rider: about 41 minutes
150 lb rider at a vigorous 14-16 mph: about 44 minutes

Is cycling or running better for burning calories?

Minute for minute, running usually wins. Because cycling is non-weight-bearing, you are not lifting your full body weight with every stride, so a moderate ride burns less than a moderate run at the same perceived effort. A 30-minute moderate run burns about 333 calories for a 150-pound person, versus around 273 calories for 30 minutes of moderate cycling.

But cycling lets you go much longer with less impact, which is why many people end up burning more total calories on a bike over a week. It is also far easier on the knees, hips, and back. If you are comparing options, our guides to how many calories running burns break down the exact numbers side by side. The best choice is the one you will do consistently.

What factors affect how many calories cycling burns?

Body weight

Weight is the single biggest factor. A 200-pound rider burns about 65 percent more calories than a 120-pound rider at the same speed. This is why a single generic calorie number is misleading: it assumes an "average" rider who does not exist.

Intensity and resistance

Higher resistance and faster cadence push you into higher MET zones. Jumping from a 12 mph cruise (8 METs) to a 16 mph push (12 METs) increases your burn by 50 percent. On a stationary bike, cranking the resistance is the lever that matters most.

Terrain and wind

Climbing a 5 percent grade can nearly double the energy cost compared to flat ground, and a strong headwind has a similar effect. This is why outdoor rides with hills tend to out-burn flat indoor sessions at the same average speed.

Afterburn (EPOC)

High-intensity interval rides elevate your metabolism for hours afterward, a phenomenon called excess post-exercise oxygen consumption (EPOC). A hard interval session can add an extra 50 to 150 calories to your daily burn, while steady easy spinning produces a much smaller afterburn.

Frequently Asked Questions

How many calories does cycling burn in 1 hour?

At a moderate 12 to 14 mph pace, one hour of cycling burns about 436 calories for a 120-pound person, 545 for a 150-pound person, 654 for a 180-pound person, and 727 for a 200-pound person. Vigorous riding above 14 mph can push these numbers past 900 calories per hour.

Is 30 minutes of cycling a day enough to lose weight?

Yes, if it helps create a calorie deficit. Thirty minutes of moderate cycling burns roughly 250 to 365 calories, which over a week can add up to about half a pound of fat loss, but only if your diet does not compensate for the extra burn. Pairing daily rides with a 300 to 500 calorie dietary deficit produces the most reliable results.

Does cycling burn belly fat?

Cycling cannot target belly fat directly because spot reduction is a myth. However, the overall calorie deficit it creates does reduce total body fat, and visceral belly fat is often among the first stores your body burns. Combining steady rides with interval sessions and adequate protein accelerates the process.

Why does my Peloton say I burned more calories than my watch?

The two devices use different assumptions. Bike consoles estimate calories from cadence and resistance using a generic rider profile, while wrist trackers estimate from heart rate. Both are imperfect, and studies show fitness devices overestimate energy expenditure by an average of about 27 percent. Treat either number as a rough guide, not a precise total.

Is cycling better than walking for burning calories?

Moderate cycling burns more per minute than walking because it covers more ground at a higher intensity. A 30-minute moderate ride burns about 273 calories for a 150-pound person, versus roughly 140 calories for a 30-minute walk. Walking, however, requires no equipment and is the easiest activity for most people to do daily.

How Kalo Helps You Turn Cycling Into Real Fat Loss

Calorie burn is only half the equation. If your bike console is off by 27 percent on the burn side, and you are estimating your food intake by eye, your entire deficit is built on guesswork. Kalo solves the food side with precision so your rides actually count.

With Kalo's AI-powered photo tracking, you snap a picture of your meal and get an instant calorie and macro breakdown, no manual logging required. Photograph that post-ride smoothie bowl and Kalo separates the banana, granola, peanut butter, and yogurt, estimates each portion, and shows you whether it just erased the 400 calories you worked for. That feedback loop is what turns a good ride into steady, visible progress.
