Calories burned cycling: Road vs gravel vs MTB - which bike burns the most calories?

If you've ever finished a long ride absolutely famished, you're experiencing firsthand just how demanding cycling can be on your energy reserves. But when it comes to calories consumed when cycling, there's no single magic number. It varies wildly depending on your bike type, riding style, terrain, and even how you're positioned on the saddle.

For most adults, cycling burns roughly 300 to 900 calories per hour. That is a wide range because a relaxed roll through town and a hard, hilly training ride may both count as cycling, but both demand different things from your body.  

Research into commuter cycling illustrates the point nicely. In one field study, riders working at a self-selected pace averaged 540 kcal per hour, but the variation between individuals was considerable (de Geus et al., 2007). So, when somebody asks, “how many calories does cycling burn?”, the honest answer is that it burns enough to make cycling excellent exercise, but the precise figure depends on the rider and the ride. 

These broad estimates are a useful starting point for a rider weighing around 70 to 75 kg: 

These are only estimates, of course. A lighter rider will usually use less energy at the same speed. A heavier rider, on the other hand, will use more. 

Ever wondered what makes one person a better climber than the other? It’s all about the relation between rider weight and effort. The reason rider weight matters is because moving more mass generally requires more energy, particularly uphill. Effort matters even more.

Pushing 250 watts demands more energy than turning the pedals at 100 watts, whatever the speed display says. Climbs, mud, loose gravel, headwinds and repeated accelerations raise the cost too. Add in your riding position, tyres, luggage, temperature and fitness, and you’ll see even more variation in the actual number of calories burned.

Here's an overview of the most important factors influencing the number of calories you burn on your bike ride.

• Intensity: Do you train hard or prefer a leisurely pace? The more effort you put into pedalling, the higher your pedalling force, cadence, speed, and calories burned.
• Fitness-Level: Are you new to cycling or exercise, or do you already have a solid muscle mass? Gaining muscle increases energy expenditure on bike rides because muscle burns more calories than fat. You can lose weight more effectively with the resulting higher basal metabolic rate.
• Type of route: Do you seek out flat routes or head for the hills on your rides? Routes with climbs are optimal for increasing calorie consumption compared to flat sections. As soon as you ride your bike briskly uphill, more calories are burned due to the increased energy consumption of your muscles. The terrain will affect how hard you work and how fast you can go, with traffic lights, potholes and other road users all affecting your calorie burn.
• Wind conditions: Cycling into a headwind - curse or blessing? A headwind may not affect mountain bike trail riders, but out on the open road, you’ll see cyclists going into the wind, tucked into their handlebars with determination, and their counterparts going the other way sitting upright and relaxing at high speed. But, if posture is correct, the harder you work to overcome resistance when pedalling, the greater the number of calories burned bike riding will be as a result.
• Physique: Age, gender, and weight affect how many calories you burn while cycling. Cyclists' energy requirements and energy consumption differ for the same distance and speed depending on the proportion of muscle mass and fat tissue, hormone levels and other physiological characteristics.

A bicycle does not burn calories, you do. A quick road bike means you get steady speed, a gravel bike makes long mixed-surface adventures possible, and a mountain bike turns technical ground into a succession of short efforts.

Comparing biking calories by the hour can therefore miss the bigger picture. A 4-hour gravel ride may use more total energy than a full on 60-minute MTB session.

Road bikes = rhythm. Low rolling resistance and an efficient position make a steady moderate or hard effort easier to hold. Fast group rides, long climbs and tempo sessions can move you towards the upper end of the hourly calorie-burn ranges. 

If road cycling is your preferred way to build fitness, cover long distances or ride at speed, choosing the right bike can make a big difference. Explore our road bike range to see the different options available, and check out our road bike buying guide to learn more about the differences between aero, race, endurance and all-road bikes and find the best fit for your riding goals.

Gravel adds resistance and unpredictability. Wider tyres, softer surfaces and rolling terrain can require more effort at a given speed, but the real advantage is often duration. Stable handling and the freedom to link roads, tracks and trails can turn a planned 2-hour ride into a full day adventure.

If you're considering spending more time off the beaten path, choosing the right gravel bike can make all the difference. From race-focused models built for speed to adventure-ready bikes designed for exploration, our gravel bike range has options for every riding style. Explore our gravel bikes or learn more in our gravel bike buying guides to find the right setup for your next ride.

There’s a good reason why you feel exhausted after even a short and snappy mountain bike ride. Technical climbs, punchy accelerations and constant pace changes create an intermittent effort pattern. Research describes high cardiovascular demand and repeated high-power bursts thanks to the terrain you inevitably ride on a mountain bike ride (Arriel et al., 2022). Arms and shoulders work too, quietly absorbing impacts and correcting the bike.

The one metric you should well and truly ignore when riding off-road is average speed. On a rooty climb, you could be giving it your all and the local run club folks can still smoke you. Check out the our mountain bike range to find your next off-road dream machine. The MTB buying guide will tell you all you need to know from efficient cross-country bikes through to longer-travel trail machines.

Electrical assistance usually lowers intensity on the same route. One comparison found lower oxygen uptake on e-bikes, although riders still accumulated meaningful moderate activity (Langåker et al., 2017). Especially if the aim of the game for you is spending more time outside and pushing more in your zone 2, then riding your e-bike is a great way to push in your zone 2 without completely exhausting yourself and spending longer time riding your bike. So, riding an e-bike or pedelec, you can still burn loads of calories, but you’ll go faster, further and with more ease than you would on a conventional bike. The decisive factor for the number of calories you burn is the selected level of motor assistance. When cycling without electric assistance, your calorie consumption is the same as on a conventional bicycle. The more you engage the motor assistance, the less your muscles will work, and your calories burned will decrease accordingly.

When riding an e-bike, the number of calories burned changes as a percentage of the motor assistance used. If the motor does half of your work, you only have to pedal half as hard, and therefore you only burn 50% of the calories. In one hour of cycling, you burn around 250 kcal, whereas the average calorie consumption without motor assistance is 500 kcal.

You can find out more about this topic in our guide to calorie consumption with an e-bike.

How many calories you burn in an hour of riding a bicycle depends on your speed and other factors. As a rule of thumb, you’d achieve the following calorie consumption during 60 minutes of cycling:

• Speed up to 15 km/h ≈ 300 kcal
• Speed up to 18 km/h ≈ 420 kcal
• Speed up to 22 km/h ≈ 600 kcal
• Speed up to 28 km/h ≈ 850 kcal
• Speed over 28 km/h ≈ 1,000 kcal

Half an hour on the bike at 18 km/h burns about 210 kcal. If you want a bike ride calorie burn of 1,000 kilocalories at that same speed, you’d need to maintain that pace for about 2.5 hours.

Distance alone does not say much about calorie consumption. The decisive factor is how fast you go and how much effort you put in, though the profile of the route and headwind also have a significant impact. For example, sprinting at full speed on a racing bike over a short 10 km stretch will actually burn fewer total calories than cycling a much longer 40 km on a trekking bike at a leisurely 15 km/h.

However, assuming a moderate, steady cycling speed of about 18 km/h, you can use these average values to estimate how distance relates to calories burned:

• 1 km: ~23 kcal
• 10 km: ~230 kcal
• 20 km: ~460 kcal
• 25 km: ~575 kcal
• 30 km: ~690 kcal
• 40 km: ~920 kcal
• 80 km: ~1,840 kcal

How you ride hugely influences comfort, handling and sustainable power. This matters more than any tiny theoretical difference in calories between postures. 

An upright position can ease strain on the neck, hands and back. A low position reduces drag at speed, but may limit breathing or comfort when unsuitable. A position that looks fast but causes an early return home is not useful. 

If you're unsure whether your current setup is helping or holding you back, take a look at our dedicated bike position guides. We cover everything from finding the perfect road bike position and optimal gravel bike fit to improving your mountain bike riding position, helping you ride more comfortably, efficiently and confidently on any terrain. 

Endurance geometry generally places the bars higher and closer for long distance comfort. This is the position you’ll usually ride on a bikepacking trip or longer training rides. Aero or race geometry places the rider lower and farther forward, prioritising reduced drag and responsive handling. Neither is universally better. Check out our road bike geometry guide for a detailed explanation on this. 

Comfort is part of performance. Numb hands, a rocking pelvis or a grumbling knee will shorten your rides. A good fit on a bike lets effort go into the pedals rather than into tolerating the bike. 

Use the Perfect Positioning System on our website to find your perfect frame size using your height and inner leg measurements. Check out the blog on our sizing guide for a sensible starting point into buying an appropriately sized bike. If you’re facing persistent discomfort, though, it is definitely worth visiting a qualified bike fitter. Over months, reliable comfort usually contributes more to calorie burning cycling than occasional heroic sessions on the wrong bike. 

To make a lot of energy available during swift and high-intensity activities such as running 100 metres, the body primarily burns carbohydrates. Then it increasingly resorts to burning fat over more extended physical efforts, such as running 10 km. These two types of energy supply both rely on the turnover of oxygen.

• Aerobic zone - If you train in the aerobic metabolism range, your body always has enough oxygen available. Your muscles gain the required energy from the inhaled atmospheric oxygen and simultaneously burn fat and the carbohydrate glycogen. The resulting CO2 is carried by the blood and exhaled through the lungs. When cycling at medium speed, you breathe faster than you would at rest, but you are not out of breath and can still talk without any problems.
• Aerobic threshold - If the load condition of your body is increased by more intensive cycling, further carbon dioxide is produced in your muscles, and it can no longer be exhaled through the lungs in the same amount of time. The CO2 content of the blood therefore increases. Glycogen is no longer wholly burned in the muscle, and lactate is released - a condition known as aerobic threshold, in which your body continues to break down and transport the glycogen residues without any problems. At the aerobic threshold, the lactate level in the blood does not rise further – it is a "steady state". At what point further lactate increase occurs depends on the fitness level of the cyclist. For inexperienced cyclists, the aerobic threshold may be at 60% of the maximum heart rate, whereas for professionals, it starts at 85%. But it averages between 80 and 90% for most. You have reached the anaerobic point when you cycle at the highest training intensity without triggering a significant increase in lactate concentration. The fitter you are, the further and faster you can go before you reach this threshold.
• Anaerobic zone - You only train in the anaerobic zone for short periods, as you are cycling at peak performance. Your body does not have enough oxygen for energy production, and carbohydrate storage is exhausted after a short time. Although the process known as glycolysis is twice as fast, a large amount of lactate accumulates in the bloodstream, which results in a rapid decline in performance, muscle burn and exhaustion. In addition, muscle hardening is possible afterwards, so stretching and cooling down are essential to reduce the risk of injuries.

A calorie deficit is necessary to lose weight permanently: You must burn more calories than you take in. However, it is essential not to take in too few calories as your body may start to reserve them, resulting in a loss of muscle mass. Every calorie consumed is then stored as fat which is how the body ensures that it can maintain vital functions such as breathing, blood circulation or digestion in the long term despite the food shortage. In many crash diets, this is how the infamous yo-yo effect sets in.

The body’s energy requirement to maintain vital processes in a state of rest is called the basal metabolic rate. The power metabolic rate is the energy it needs for any activity over and above the basal metabolic rate. The sum of basal and power metabolic rates is the total energy metabolic rate.

You can lose weight sustainably by keeping your calorie intake a little below the total energy metabolism over time. To do this, you can increase your energy consumption by doing more physical activity or reduce your energy intake by eating healthier. It's best to pay attention to both exercise and diet simultaneously. You can lose weight effectively and permanently without experiencing the yo-yo effect. If you want to maintain weight, your calorie intake and total energy expenditure should balance.

Determining your daily basal metabolic rate is the first step in calculating your calorie needs. With the revised Harris-Benedict formula, you can do this without a calorie calculator:

• Women: 447.593 + (9.247 x body weight in kg) + (3.098 x height in cm) - (4.330 x age)
• Men: 88.362 + (13.397 x body weight in kg) + (4.799 x height in cm) - (5.677 x age)

Calculation example: A 33-year-old man, 185 cm tall, and weighing 80 kg has a calculated basal metabolic rate of 1,861 kcal. For a 33-year-old woman of the same height and weight, the individual basal metabolic rate is 1,618 kcal.

In addition to the basal metabolic rate or resting energy requirement, there is the power metabolic rate, i.e., the energy required for any activity. The power metabolic rate can vary depending on whether you have a physical or sedentary job and how active you are in your free time.

Therefore, the basal metabolic rate is multiplied by a physical activity level (PAL) to determine the total energy requirement. According to the German Nutrition Society (DGE), the PAL value is between 1.2 (lying or sitting) and 2.4 (heavy physical work). For office jobs, a PAL value of 1.4 to 1.5 is assumed. For predominantly walking or standing positions, such as in catering or sales, the PAL value is 1.8 to 1.9. Those who exercise four to five times a week for 30 to 60 minutes can increase the value by 0.3.

Calculation example: The man from the previous example has an office job (1.5) but rides his bike to work and home every day (+ 0.3). He multiplies his basal metabolic rate of 1,863 kcal per day by the PAL value of 1.8 to determine his total energy requirement, which is 3,353 kcal per day.

Calorie numbers can be motivating, but false precision is unhelpful. A display reading 743 calories has not necessarily measured 743 calories. In most cases, it has estimated them from a limited set of inputs. 

Basic GPS estimates use speed, distance, elevation and personal details. Your machine cannot feel the wind, rolling resistance, drafting or technical terrain like you do. Wrist devices add movement and sometimes heart rate, yet their algorithms can produce different answers based on their varied datasets.

In a validation study of 12 wearables, most devices produced physical-activity energy estimates that differed significantly from criterion methods (Murakami et al., 2019). Treat the number as a trend, rather than a sure-shot result.

Your heart rate is basically your body’s response to work. It is affordable and useful, but heat, fatigue, caffeine, hydration and stress can all shift it. It also reacts slowly to short, hard efforts.

A power meter measures the mechanical work delivered to the bike. This makes it the most useful field tool for estimating cycling energy. A common practical approximation is that kilojoules of recorded work are numerically close to dietary kilocalories used, because human cycling efficiency offsets the conversion between the units.

It remains an estimate, as efficiency varies between riders and across intensities (Matomäki et al., 2019). Our guide to training with power explains how to kickstart using a power meter. Some road models come fitted with power meters to save you buying and installing it separately. And if you'd like to learn more about training with heart rate or power, check out our guide on heart rate vs power for cycling and find out which approach best suits your goals.

Your cycling computer brings GPS, heart rate, power, cadence and elevation together. Apps turn the ride into longer-term patterns: volume, load, recovery and progress. Compatible sensors and mounts make the setup cleaner, but at the end of the day, it’s all down to your consistency.

Use the same device and settings when comparing rides. Even if the absolute figure indicating calories burned on your ride is imperfect, a stable system can still show whether workload is rising or recovery weeks are actually easier.

Power zones are what separates endurance riding, threshold work and short anaerobic efforts, even when wind makes speed meaningless. They also push you to pace better, so that every ride doesn’t turn into an FTP test.

The aim is not to make every ride punishing. Useful variety raises energy expenditure while preserving recovery and the desire to ride again.

Steady rides make sure that you spread out your energy expenditure through time. They develop aerobic fitness and can be repeated frequently. Intervals raise the amount of energy you use and train the ability to work hard, but they also require more recovery.

Both belong in a balanced week. Indoor-cycling research found similar total energy expenditure from different interval sequences when overall work was matched (Fusco et al., 2021). One or two hard sessions alongside easier riding is plenty.

Hills raise intensity naturally. Gravity demands more power and repeated climbs develop cardiovascular fitness and muscular endurance. Loose surfaces and headwinds add resistance too.

Start with short climbs at a controlled pace. Add duration or repetitions gradually, and use easy gears and higher cadence to protect your knees. Sustainable progression will do more for burning calories than one huge session that asks for a two-week recovery.

There’s no single "best" bike for burning calories. What matters most is finding a bike that motivates you to ride more often, for longer, and with greater enjoyment. Whether that's chasing speed on the road, exploring new gravel routes or tackling technical trails, consistency will always have the biggest impact on your fitness.

So, no bike category wins every calorie contest. MTB may feel hardest minute for minute, road makes sustained effort easier to control, and gravel encourages long days. The winner is the bike that matches your body, routes and curiosity.
