Calories Burned Stationary cycling at a moderate effort at 85 kg — 595 kcal per Hour
Stationary cycling at a moderate effort at 85 kg (176–198 lb) burns about 595 kcal per hour. That figure comes from the activity's MET value of 7.0 in the 2011 Compendium of Physical Activities, multiplied by body weight: 7.0 × 85 kg × 1 hour = 595 kcal. This page works the numbers out in full — for 15, 30, 45, 60 and 90 minutes, across all four weight bands, and against four comparable activities at the same weight — so you can plan sessions with real figures instead of guessing.
Moderate stationary cycling means a steady, conversational pace on an exercise bike — enough resistance to feel your legs working and your breathing deepen, but not so hard that you cannot talk in full sentences. On most bikes that is a perceived effort of about 5 or 6 out of 10, a cadence near 70–80 revolutions per minute, and a heart rate in the moderate zone. It is the default pace for a 30–45 minute indoor ride, and it is also the pace many people use for a warm-up before a harder session or a cool-down afterwards.
It suits almost everyone: beginners building a base, people returning to exercise after a break, older adults who want a low-impact workout, and anyone whose knees or ankles object to running. Because the bike supports your weight, the joints take far less pounding than they do on a run, while the legs, glutes and heart still get a thorough workout. If you are short on time, a moderate ride is easy to fit in before work or in a lunch break, and it needs no weather, no traffic and no special clothing beyond comfortable shoes.
If you sit at the heavier end of the scale, your figures will be the highest in this family — that is expected, because a heavier body costs more energy to move. Do not read a bigger number as a better workout: the effort is the same, and the calorie total is physics, not a score. If you are carrying extra weight and new to exercise, the low-impact options in this family are a kind place to start.
Calculate your own numbers
Use the Calorie calculator to work out your own burn for stationary cycling at a moderate effort at your exact weight and session length. Enter your weight, pick the activity and set the duration, and the tool applies the same MET formula shown below. The step calorie calculator is a useful companion if you track daily movement alongside your sessions.

The formula, shown and cited
The standard way to estimate the energy cost of an activity is the MET formula from the Compendium of Physical Activities (Ainsworth et al., Medicine & Science in Sports & Exercise, 2011; 43(8): 1575–1581):
Calories (kcal) = MET × body weight (kg) × duration (hours)
One MET is the energy you use sitting quietly at rest — about 1 kcal per kilogram of body weight per hour. An activity rated at 7.0 METs therefore uses 7.0 times as much energy as resting. The Compendium's MET values come from published studies that measured oxygen use during each activity, so they are measured averages, not guesses. The value used here, 7.0, is the one recorded for stationary cycling at a moderate effort in the FitCalc activity data.
Worked through for this page:
- MET for stationary cycling at a moderate effort: 7.0
- Body weight: 85 kg (the midpoint of the 80-90 kg band, 176–198 lb)
- Duration: 1 hour
- Calculation: 7.0 × 85 × 1 = 595 kcal
For a 30-minute session the same calculation is 7.0 × 85 × 0.5 = 298 kcal. Nothing else is hidden in the maths — if your weight or duration changes, only those two numbers change.
Your numbers at 85 kg
| Duration | Calculation | Calories burned |
|---|---|---|
| 15 minutes | 7.0 × 85 × 0.25 | 149 kcal |
| 30 minutes | 7.0 × 85 × 0.5 | 298 kcal |
| 45 minutes | 7.0 × 85 × 0.75 | 446 kcal |
| 60 minutes | 7.0 × 85 × 1 | 595 kcal |
| 90 minutes | 7.0 × 85 × 1.5 | 892 kcal |
That is about 9.9 kcal per minute of stationary cycling at a moderate effort at this weight. A short session still counts: even 15 minutes burns 149 kcal, and three 15-minute sessions across a day add up to the same 446 kcal as one 45-minute session.
How the burn changes with body weight
The MET value stays the same — it describes the activity, not the person — but the calorie total scales with weight, because a heavier body costs more energy to move:
| Body weight | Calories per hour | Calories per 30 minutes |
|---|---|---|
| 55 kg | 385 kcal | 192 kcal |
| 65 kg | 455 kcal | 228 kcal |
| 75 kg | 525 kcal | 262 kcal |
| 85 kg | 595 kcal | 298 kcal |
Two people doing the same activity for the same time can therefore burn quite different amounts, and that is expected — it is physics, not a mistake in the formula. If your weight sits between two rows, your figure sits between the two values.
How stationary cycling at a moderate effort compares
Here is stationary cycling at a moderate effort against four other activities at the same 85 kg, all using the same MET formula:
| Activity | MET | Calories per hour at 85 kg |
|---|---|---|
| stationary cycling at a moderate effort | 7.0 | 595 kcal |
| cycling at a light effort (10–11.9 mph) | 6.8 | 578 kcal |
| swimming backstroke | 7.0 | 595 kcal |
| jogging | 7.0 | 595 kcal |
| cycling at a moderate effort (12–13.9 mph) | 8.0 | 680 kcal |
Use this table to choose, not to judge. A higher number means a harder session, not a better one: the activity you enjoy and repeat three times a week beats the activity that burns more per hour but that you quit after a fortnight. Mixing intensities across the week — one harder session, two easier ones — is usually more sustainable than doing the hardest activity every time.
Fitting stationary cycling at a moderate effort into your week
| Sessions per week | 30 minutes each | 60 minutes each |
|---|---|---|
| 2 sessions | 595 kcal | 1190 kcal |
| 3 sessions | 892 kcal | 1785 kcal |
| 5 sessions | 1488 kcal | 2975 kcal |
A good moderate session is 30 minutes at a steady pace after a five-minute easy warm-up, with a five-minute easy cool-down at the end. Twice a week is enough to notice your fitness improving; three times a week builds it faster. If you want more from the same time, add five minutes every week or two rather than cranking the resistance up suddenly. A 30-minute ride at this weight burns about 298 kcal, so three rides a week add up to roughly 892 kcal — a meaningful contribution to a weekly activity total without ever feeling punishing.
How to use the result
Use the figure on this page to plan, not to punish yourself. Add the session's calories to your total daily energy expenditure for that day, and remember the estimate carries roughly 10–20% uncertainty. Do not eat back every calorie the calculator shows: MET estimates and activity trackers both tend to overstate slightly, and a small margin keeps a weight-loss plan on track. If you are aiming to lose weight, keep the deficit modest — 300–500 kcal a day is a common, sustainable range — and keep your total intake above the safety floors of 1,200 kcal a day for women and 1,500 kcal a day for men unless a healthcare professional advises otherwise.
Set the saddle so your knee is slightly bent at the bottom of the pedal stroke — a saddle set too low is the most common cause of aching knees on a stationary bike. Keep your back fairly upright rather than hunched over the handlebars, and let your feet push through the whole pedal circle instead of stomping down. Resistance should feel like a gentle slope, not a flat road and not a hill. If you can pedal for 45 minutes without your legs fading, the resistance is about right for a moderate session; if your legs give out after ten minutes, turn it down a notch.
What the number does NOT tell you
The MET formula does not know how fit you are, how much resistance you actually used, or how efficiently you pedal. A fit cyclist burns fewer calories at the same nominal effort than a beginner, because their body wastes less energy. It also ignores the small afterburn after harder sessions, and it says nothing about the strength, balance or bone health the ride does or does not build. Stationary cycling is excellent for the heart and legs, but it is not weight-bearing, so it does little for bone density — pair it with some walking or resistance work across the week if that matters to you.
Frequently asked questions
How many calories do I burn stationary cycling at a moderate effort for 30 minutes at 85 kg?
About 298 kcal. The maths is 7.0 METs × 85 kg × 0.5 hours = 298 kcal. That is an estimate from the Compendium average — your real burn depends on the resistance you use, your cadence and your fitness. If you weigh more or less than 85 kg, use the weight table above to read your own figure.
Is moderate stationary cycling good for weight loss?
It can help, but only as part of an overall calorie deficit. At 85 kg, an hour of moderate stationary cycling burns about 595 kcal, which is a useful contribution — roughly the energy in a modest meal — but weight loss still comes from the total balance of food and activity across the week, not from one ride. Aim for a gradual loss of 0.5–1% of body weight per week, and never drop below 1,200 kcal a day (women) or 1,500 kcal a day (men) without medical supervision.
What resistance should I use for moderate stationary cycling?
Enough that your legs feel the work and your breathing deepens, but not so much that you cannot talk in full sentences or keep a cadence near 70–80 revolutions per minute. On most bikes that is the middle of the resistance range. If your legs fade after ten minutes, the resistance is too high for a moderate session; if you could ride for two hours without noticing, it is too low.
Does the calorie burn change if I weigh more or less than 85 kg?
Yes, directly. Calories = MET × weight in kg × hours, so the burn scales with body weight. At 55 kg the same hour of moderate stationary cycling burns about 385 kcal; at 85 kg it burns about 595 kcal. The MET value itself does not change with weight — it describes the intensity of the activity.
How accurate is the 7.0 MET value for moderate stationary cycling?
It is a population average from the 2011 Compendium of Physical Activities (Ainsworth et al.), which compiled measured energy costs across published studies. Individuals vary by roughly 10–20% around the average because of fitness, body composition, resistance and pedalling efficiency. Treat 595 kcal per hour as a planning estimate, not a precise measurement of your own body.
Estimates only, not medical advice. Minimum safe intakes: 1,200 kcal/day women, 1,500 kcal/day men — consult a healthcare professional before a very-low-calorie diet.
