Calories Burned on a Stationary Bike By Weight, Resistance and Duration
How many calories does a stationary bike burn? Full tables by body weight, resistance, and session length. Covers upright, recumbent, spin class, Peloton, and weekly weight loss planning.
A stationary bike burns between 210 and 840 calories per hour, depending on body weight, resistance level, and riding intensity. A 155 lb (70 kg) person cycling at moderate effort on an upright stationary bike burns approximately 476 calories per hour, based on MET 6.8 from the 2024 Adult Compendium of Physical Activities. The same rider at vigorous effort (MET 8.8 to 12.0) burns 616 to 840 calories per hour, matching or exceeding outdoor cycling output when resistance is set appropriately.
The cycling calorie calculator provides personalised stationary bike estimates across intensity levels. The cycling hub connects all cycling formats, including spin class, outdoor cycling, and mountain biking.
How Many Calories Does a Stationary Bike Burn?
Stationary bike calorie burn depends on three variables: body weight, intensity (measured in watts or effort level), and session duration. The 2024 Adult Compendium of Physical Activities assigns specific MET codes to stationary cycling at different wattage bands, making it one of the most precisely measurable indoor activities in exercise science.
The basic calorie formula is: Calories = MET × body weight (kg) × duration (hours)
At MET 6.8 (moderate effort, approximately 100 watts), a 70 kg rider burns 6.8 × 70 = 476 kcal per hour. At MET 12.0 (very vigorous, 200W+), the same rider burns 12.0 × 70 = 840 kcal per hour. Resistance and wattage, not the bike's speed display, determine actual calorie output.
Stationary Bike Calorie Burn Per Hour by Body Weight
The most important factor in stationary bike calorie output is body weight. At a fixed intensity level, heavier riders burn more calories per hour because the MET formula multiplies by mass.
Stationary Bike Calories Per Hour by Weight and Intensity
Body Weight | Moderate (MET 6.8) | Vigorous (MET 8.8) | Very Vigorous (MET 12.0) |
|---|---|---|---|
120 lb (54 kg) | 367 kcal | 475 kcal | 648 kcal |
140 lb (64 kg) | 435 kcal | 563 kcal | 768 kcal |
155 lb (70 kg) | 476 kcal | 616 kcal | 840 kcal |
165 lb (75 kg) | 510 kcal | 660 kcal | 900 kcal |
185 lb (84 kg) | 571 kcal | 739 kcal | 1,008 kcal |
200 lb (91 kg) | 618 kcal | 800 kcal | 1,092 kcal |
215 lb (97 kg) | 664 kcal | 860 kcal | 1,170 kcal |

Calories burned stationary bike at 150 pounds at moderate effort: approximately 459 kcal per hour. A 215 lb rider at very vigorous effort can exceed 1,000 kcal per hour on a stationary bike approaching the output of competitive outdoor cycling.
Stationary Bike Calories by Wattage
Wattage is the most accurate input for stationary bike calorie estimates because it measures actual mechanical output rather than self-reported effort. The 2024 Compendium includes wattage-specific MET entries for stationary cycling a level of precision not available for most other activities.
Stationary Bike Calories Per Hour by Wattage (155 lb / 70 kg)
Watts | MET | Calories Per Hour | Calories in 30 Min | Calories in 45 Min |
|---|---|---|---|---|
Under 50W | 3.5 | 245 kcal | 122 kcal | 184 kcal |
75W | 5.5 | 385 kcal | 192 kcal | 289 kcal |
100W | 6.8 | 476 kcal | 238 kcal | 357 kcal |
125W | 8.0 | 560 kcal | 280 kcal | 420 kcal |
150W | 8.8 | 616 kcal | 308 kcal | 462 kcal |
175W | 10.0 | 700 kcal | 350 kcal | 525 kcal |
200W+ | 12.0 | 840 kcal | 420 kcal | 630 kcal |
2024 Compendium wattage-specific MET entries.
A rider sustaining 150 watts for 1 hour burns approximately 616 calories. Moving from 100 watts to 150 watts (a 50W increase) adds approximately 140 kcal per hour to the output. Riders with a power meter or smart bike display have a direct path to precise calorie tracking that speed-based calculators cannot match.
Stationary Bike 30 Minutes Calories by Weight
Thirty minutes is the most common stationary bike session length. The calorie output for 30 minutes spans a wide range depending on body weight and effort.
Stationary Bike 30 Minutes Calories by Body Weight
Body Weight | Light (MET 3.5) | Moderate (MET 6.8) | Vigorous (MET 8.8) | Very Vigorous (MET 12.0) |
|---|---|---|---|---|
120 lb (54 kg) | 95 kcal | 184 kcal | 238 kcal | 324 kcal |
140 lb (64 kg) | 111 kcal | 218 kcal | 282 kcal | 384 kcal |
155 lb (70 kg) | 122 kcal | 238 kcal | 308 kcal | 420 kcal |
185 lb (84 kg) | 146 kcal | 285 kcal | 369 kcal | 504 kcal |
200 lb (91 kg) | 158 kcal | 309 kcal | 400 kcal | 546 kcal |
215 lb (97 kg) | 170 kcal | 332 kcal | 430 kcal | 585 kcal |
According to Harvard University data, a 155 lb (70.3 kg) person burns approximately 252 calories in 30 minutes of moderate stationary biking. The 2024 Compendium MET 6.8 calculation above produces 238 kcal very close alignment. The slight variation reflects the different formula versions used; both represent credible moderate-effort estimates.
For sessions extending beyond 30 minutes, the 1-hour cycling calories page covers 60-minute stationary and outdoor data for all body weights.
Recumbent Bike Calories Burned
Recumbent bikes burn approximately 12 to 15% fewer calories than upright stationary bikes at the same wattage and duration. According to BodySpec (2026) citing published exercise science research, the reclined position removes core muscle engagement from the pedalling motion, reducing total active muscle mass and therefore total energy expenditure.
Recumbent vs Upright Bike Calories (30 Min, Moderate Effort, 155 lb)
Bike Type | MET | Calories in 30 Min |
|---|---|---|
Upright stationary, moderate | 6.8 | 238 kcal |
Recumbent, moderate | 5.8 to 6.0 | 203 to 210 kcal |
Upright stationary, vigorous | 8.8 | 308 kcal |
Recumbent, vigorous | 7.5 | 263 kcal |
The 12 to 15% calorie reduction of recumbent riding is real but does not eliminate its value for weight loss. A recumbent session is easier on the lower back and often allows longer sessions, which can compensate for the per-minute reduction. A 60-minute moderate recumbent session burns approximately 408 to 420 kcal for a 155 lb rider comparable to a 30 to 35 minute vigorous upright session.
Stationary Bike Calories Burned Female vs Male
Biological sex affects stationary bike calorie burn primarily through differences in average body weight and lean muscle mass rather than metabolic rate alone. At the same body weight, the MET formula produces identical calorie outputs for male and female riders.
In practice, the average adult female weighs less than the average adult male, which produces lower calorie totals at the same intensity. Using a typical 140 lb female and a typical 185 lb male, both cycling at moderate effort for 30 minutes:
140 lb female, moderate 30 min: approximately 218 kcal
185 lb male, moderate 30 min: approximately 285 kcal
The 31% difference is entirely explained by the 32% weight difference. A 185 lb female and a 185 lb male burn identical calories on a stationary bike at the same effort level and duration, because the formula does not differentiate by sex.
Stationary Bike vs Outdoor Cycling: Calorie Comparison
Stationary bike sessions burn 5 to 12% fewer calories than outdoor cycling at the same perceived effort. Moderate outdoor cycling uses approximately MET 8.0 while a moderate stationary session uses MET 6.8. The difference comes from three factors absent indoors: wind resistance, variable terrain, and balance adjustments.
Stationary vs Outdoor Cycling (30 Min, 155 lb)
Format | MET | Calories in 30 Min |
|---|---|---|
Stationary, light | 3.5 | 122 kcal |
Stationary, moderate | 6.8 | 238 kcal |
Outdoor, moderate 12 to 14 mph | 8.0 | 280 kcal |
Stationary, vigorous | 8.8 | 308 kcal |
Spin class, structured | 9.0 | 315 kcal |
Outdoor, vigorous 14 to 16 mph | 10.0 | 350 kcal |
Stationary, very vigorous 200W+ | 12.0 | 420 kcal |
The stationary bike gap is easily closed by increasing resistance. A vigorous stationary session at 150 to 175 watts matches and exceeds a moderate outdoor ride. Maximum stationary output at 200W+ (MET 12.0) exceeds most recreational outdoor cycling sessions.
For outdoor calorie data, see the 30-minute cycling page and 1-hour cycling page. For indoor class formats, the indoor cycling calories page covers spin class and structured HIIT cycling.
Why Are Exercise Bike Calorie Displays Inaccurate?
Built-in calorie displays on exercise bikes overestimate actual output by 20 to 30% on average, according to multiple independent calculator analyses (Bikingbro, BodySpec). The machines use a population-average formula that ignores the individual rider's actual body weight. A 120 lb rider and a 200 lb rider performing identical sessions receive the same displayed calorie count on most basic machines, despite the reality that the heavier rider burns approximately 67% more.
Smart bikes like Peloton use heart rate data in addition to power output, which improves accuracy but introduces a separate source of error. Heart rate varies with caffeine intake, dehydration, sleep quality, and heat none of which change actual calorie burn. The 2024 Compendium explicitly excludes heart-rate-based calorie data due to this variability.
MET-based estimates anchored to your actual body weight (as used in the tables above) are more reliable than machine displays for workout planning and weight loss tracking.
Stationary Bike Weight Loss: Weekly Planning
A stationary bike creates a predictable weekly calorie deficit when used consistently. For weight loss planning, the tables below show outputs across the most common session lengths for a 155 lb rider at moderate effort.
Weekly Calorie Output from Stationary Bike Sessions (155 lb, Moderate MET 6.8)
Session Length | Per Session | 3x/Week | 5x/Week | Daily |
|---|---|---|---|---|
20 min | 159 kcal | 477 kcal | 795 kcal | 1,113 kcal |
30 min | 238 kcal | 714 kcal | 1,190 kcal | 1,666 kcal |
45 min | 357 kcal | 1,071 kcal | 1,785 kcal | 2,499 kcal |
60 min | 476 kcal | 1,428 kcal | 2,380 kcal | 3,332 kcal |
Five 30-minute moderate stationary sessions per week produce 1,190 weekly calories for a 155 lb rider. Combined with a 250 kcal daily dietary reduction, this creates a weekly deficit of approximately 2,940 kcal, enough to support approximately 0.84 lb of weekly fat loss.
To find your full daily energy balance and understand exactly how stationary cycling sessions contribute to your maintenance calorie target, the TDEE calculator produces your personalised daily energy expenditure figure.
The calories burned calculator covers all other activity types for mixed-exercise weeks. For the broader context of how stationary biking compares to outdoor cycling and other formats, the main calories burned guide provides cross-activity reference tables.
Resistance Level Effect on Stationary Bike Calorie Burn
Resistance level is the primary control for the stationary bike calorie output. Unlike outdoor cycling, where speed and terrain determine effort, indoor cycling allows direct manipulation of resistance to hit specific calorie targets within a fixed session length.
The relationship between resistance and calorie burn is not linear at the extremes. Moving from resistance level 5 to resistance level 10 on a standard stationary bike approximately doubles watts output from roughly 75W to 150W. Moving from level 10 to level 15 raises watts from approximately 150W to 200W, a 33% increase. The calorie gain is proportional to watts at every step.
Approximate Resistance Level to Watt to Calorie Mapping (30 Min, 155 lb)
Resistance Level (Approx) | Approx Watts | MET | 30-Min Calories |
|---|---|---|---|
Level 3 to 4 (light) | 50W | 3.5 | 122 kcal |
Level 5 to 6 (moderate low) | 75W | 5.5 | 192 kcal |
Level 7 to 8 (moderate) | 100W | 6.8 | 238 kcal |
Level 9 to 11 (vigorous) | 150W | 8.8 | 308 kcal |
Level 12 to 15 (very vigorous) | 200W+ | 12.0 | 420 kcal |
Watt estimates based on Compendium MET midpoints and standard stationary bike resistance profiles.
The resistance level numbers vary by bike brand. A resistance level 10 on a Peloton is not the same as a level 10 on a basic gym upright bike. Using wattage as the reference (when available) produces more consistent calorie estimates across bike brands than resistance levels do.
For outdoor cycling equivalents, the 10-mile cycling page and 20-mile cycling page show how these watt-based efforts translate to road ride distances.
Frequently Asked Questions About Calories Burned on a Stationary Bike
How Many Calories Does a Stationary Bike Burn?
A stationary bike burns between 210 and 840 calories per hour, depending on body weight and effort level. A 155 lb (70 kg) person at moderate effort (MET 6.8) burns approximately 476 calories per hour. At vigorous effort (MET 8.8), the same person burns approximately 616 calories per hour. At a very vigorous effort (200W+, MET 12.0), the output reaches 840 calories per hour.
How Many Calories Does 30 Minutes on a Stationary Bike Burn?
A 155 lb (70 kg) person burns approximately 238 calories in 30 minutes of moderate stationary biking. At vigorous effort, the same person burns approximately 308 calories in 30 minutes. At very vigorous effort (200W+), the 30-minute output reaches approximately 420 calories.
Does a Stationary Bike Burn as Many Calories as Outdoor Cycling?
A stationary bike burns approximately 5 to 12% fewer calories than outdoor cycling at the same perceived effort. Moderate outdoor cycling (MET 8.0) produces more calories per minute than moderate stationary cycling (MET 6.8) because outdoor riding adds wind resistance, terrain, and balance demands. This gap fully closes when stationary resistance is raised to match outdoor exertion levels.
How Many Calories Does a Stationary Bike Burn in a Week?
A 155 lb person cycling at moderate effort on a stationary bike burns approximately 238 calories per 30-minute session. At 5 sessions per week, this produces 1,190 weekly calories from exercise. At 7 sessions per week, the total reaches approximately 1,666 weekly calories enough to support approximately 0.5 lb of weekly fat loss from cycling alone.
