Calories Burned Cycling 30 Minutes By Weight and Speed
How many calories does cycling 30 minutes burn? Full tables by body weight, speed, and bike type. Covers outdoor, stationary, indoor cycling, and 30-minute weight loss planning.
Cycling for 30 minutes burns between 140 and 600 calories, depending on body weight, speed, and bike type. A 155 lb (70 kg) rider at a moderate pace (12 to 14 mph) burns approximately 280 calories in a 30-minute outdoor ride, according to the 2024 Adult Compendium of Physical Activities. The same rider on a stationary bike at moderate effort burns approximately 252 calories in the same period, because indoor cycling removes wind resistance and variable terrain from the equation.
The cycling calorie calculator generates a personalised 30-minute estimate using your body weight and speed. For a complete picture of how 30-minute cycling fits into your full daily energy burn, the calories burned cycling hub covers all formats, speeds, and durations in one place.
How Many Calories Does Cycling 30 Minutes Burn by Weight?
Body weight is the single largest variable in 30-minute cycling calorie output. The Metabolic Equivalent of Task (MET) formula:
Calories = MET × weight (kg) × duration (hours)
It scales linearly with mass, meaning a 25% weight difference produces a 25% calorie difference at the same speed and duration.
The table below uses MET 8.0, the 2024 Compendium value for moderate outdoor cycling at 12 to 14 mph, which is the most common training pace for recreational riders.
Calories Burned Cycling 30 Minutes by Body Weight (Moderate Pace, Outdoor)
Body Weight | Calories in 30 Min | Calories Per Hour |
|---|---|---|
120 lb (54 kg) | 216 kcal | 432 kcal |
130 lb (59 kg) | 236 kcal | 472 kcal |
140 lb (64 kg) | 254 kcal | 509 kcal |
150 lb (68 kg) | 272 kcal | 544 kcal |
155 lb (70 kg) | 280 kcal | 560 kcal |
165 lb (75 kg) | 300 kcal | 600 kcal |
185 lb (84 kg) | 336 kcal | 672 kcal |
200 lb (91 kg) | 364 kcal | 728 kcal |
215 lb (97 kg) | 390 kcal | 780 kcal |

For cycling 30 minutes at 150 pounds, the output at moderate pace is approximately 272 calories. A 200 lb rider at the same intensity burns 34% more (364 kcal) simply because of the additional mass being moved.
How Many Calories Does a 30-Minute Bike Ride Burn by Speed?
Speed changes 30-minute calorie output more dramatically than any other variable except body weight. The 2024 Compendium assigns MET values across a full speed range: from MET 4.0 at leisure pace under 10 mph to MET 16.0 at competitive race speeds above 19 mph.
30-Minute Cycling Calories by Speed (155 lb / 70 kg)
Speed | MET | Calories in 30 Min |
|---|---|---|
Leisure under 10 mph | 4.0 | 140 kcal |
Moderate 12 to 14 mph | 8.0 | 280 kcal |
Vigorous 14 to 16 mph | 10.0 | 350 kcal |
Fast 16 to 19 mph | 12.0 | 420 kcal |
Racing above 19 mph | 16.0 | 560 kcal |

Cycling at vigorous pace (14 to 16 mph) for 30 minutes burns 2.5 times more calories than a leisurely 30-minute ride at under 10 mph. This is the most time-efficient lever for increasing 30-minute calorie output: raising speed by 4 to 6 mph doubles the burn without adding a single minute to the session.
Calories Burned Cycling 30 Minutes at 12 mph
At exactly 12 mph, a 155 lb (70 kg) rider burns approximately 280 calories in 30 minutes, using the MET 8.0 value from the 2024 Compendium. This speed sits at the lower end of moderate intensity, where breathing is elevated but a full conversation remains possible.
Body Weight | Calories at 12 mph (30 Min) |
|---|---|
130 lb (59 kg) | 236 kcal |
150 lb (68 kg) | 272 kcal |
155 lb (70 kg) | 280 kcal |
175 lb (79 kg) | 316 kcal |
185 lb (84 kg) | 336 kcal |
200 lb (91 kg) | 364 kcal |
Cycling 30 minutes at 12 mph burns approximately the same calories as a 45-minute brisk walk for a 155 lb person (walking at 3.5 mph burns roughly 225 kcal in 45 minutes). This makes a 30-minute 12 mph ride the time-efficient equivalent of nearly a full hour of brisk walking.
Stationary Bike 30 Minutes Calories
Stationary bike calorie burn for a 30-minute session runs approximately 5 to 12% lower than outdoor cycling at the same perceived effort. According to Harvard University data, a 155 lb (70.3 kg) person burns approximately 252 calories in 30 minutes of moderate stationary biking, versus 288 calories at the same effort outdoors.
The difference exists because stationary bikes eliminate wind resistance, coasting, and terrain changes three energy costs that are always present on an outdoor ride. However, increasing resistance on a stationary bike to compensate fully closes this gap. At vigorous stationary effort, output can match or exceed moderate outdoor cycling.
Stationary Bike 30 Minutes Calories by Intensity (155 lb / 70 kg)
Intensity | Watts (Approx) | MET | Calories in 30 Min |
|---|---|---|---|
Light | Under 50W | 3.5 | 122 kcal |
Moderate | 100W | 6.8 | 238 kcal |
Vigorous | 150W | 8.8 | 308 kcal |
Very vigorous | 200W+ | 12.0 | 420 kcal |
Source: 2024 Compendium wattage-specific MET entries for stationary cycling.
Built-in calorie displays on exercise bikes overestimate actual output by 20 to 30% on average because they use a generic formula that ignores actual body weight. The MET-based estimates above, tied to your specific weight, produce more accurate figures. For the complete breakdown across all bike types including recumbent and Peloton, see the stationary bike calories page.
Indoor Cycling 30 Minutes Calories
Indoor cycling in a structured class format burns more than a standard 30-minute stationary session because spin class instructors incorporate standing climbs, sprint intervals, and resistance changes that push average intensity above steady-state pedalling. Spin class carries a dedicated MET value of 9.0 in the 2024 Compendium, compared to MET 6.8 for a moderate stationary ride.
Indoor Cycling 30 Minutes by Body Weight
Body Weight | 30-Min Moderate Stationary | 30-Min Spin Class |
|---|---|---|
125 lb (57 kg) | 192 kcal | 257 kcal |
155 lb (70 kg) | 238 kcal | 315 kcal |
185 lb (84 kg) | 285 kcal | 378 kcal |
215 lb (97 kg) | 331 kcal | 439 kcal |
Standing climbs during a 30-minute spin class add approximately 12 to 15% more calorie output per 10-minute climbing segment versus seated riding at the same resistance. A 30-minute structured indoor class at MET 9.0 produces roughly the same burn as a vigorous 30-minute outdoor ride at 14 to 16 mph. For a full indoor cycling calorie reference including Peloton data, the indoor cycling calories page covers all formats in detail.
30-Minute Cycling Calorie Comparison: Outdoor vs Stationary vs Spin
The three main formats produce meaningfully different 30-minute outputs at equivalent session types for a 155 lb rider.
Format | MET | Calories in 30 Min (155 lb) |
|---|---|---|
Stationary bike, moderate | 6.8 | 238 kcal |
Outdoor cycling, moderate 12 to 14 mph | 8.0 | 280 kcal |
Spin class (structured indoor) | 9.0 | 315 kcal |
Outdoor cycling, vigorous 14 to 16 mph | 10.0 | 350 kcal |
Stationary bike, very vigorous 200W+ | 12.0 | 420 kcal |
Spin class outperforms a standard 30-minute outdoor moderate ride by approximately 12.5% because the structured interval format sustains higher average intensity across the session. Maximum 30-minute output comes from vigorous-to-very vigorous indoor riding with high resistance, not from standard steady-state sessions.
What Factors Affect 30-Minute Cycling Calorie Burn?
Six variables determine how many calories a specific 30-minute cycling session produces.
Body weight: The largest single factor. Each additional 10 lb of body weight adds approximately 15 to 20 kcal to a 30-minute moderate ride.
Speed or resistance: Doubling from leisure pace (10 mph, MET 4.0) to vigorous pace (16 mph, MET 12.0) triples calorie output in the same 30 minutes.
Terrain: Hills add 15 to 50% to flat-ground estimates at the same average speed. A 30-minute hilly outdoor ride at 12 mph burns significantly more than a flat 30 minutes at 12 mph.
Indoor vs outdoor: Outdoor riding burns 5 to 12% more per minute than stationary at matched effort because of wind resistance.
Fitness level: More experienced cyclists develop better pedalling efficiency over time. A fit cyclist at MET 8.0 produces more mechanical output per calorie than a beginner, meaning beginners may burn slightly more per session at the same perceived effort.
Riding position: Standing during climbs adds approximately 12 to 15% more calorie output than seated riding at the same resistance and cadence.
Cycling 30 Minutes for Weight Loss
A single 30-minute cycling session at moderate pace creates a calorie burn of 240 to 360 kcal for most adults. Over a week of consistent riding, this accumulates into a meaningful calorie deficit.
Weekly Calorie Output from 30-Minute Cycling Sessions (155 lb, Moderate Pace)
Sessions Per Week | Weekly Calories | Monthly Calories | Monthly Fat Loss |
|---|---|---|---|
3 sessions | 840 kcal | 3,360 kcal | ~0.96 lb |
4 sessions | 1,120 kcal | 4,480 kcal | ~1.28 lb |
5 sessions | 1,400 kcal | 5,600 kcal | ~1.60 lb |
7 sessions | 1,960 kcal | 7,840 kcal | ~2.24 lb |
3,500 kcal approximately equals 1 lb of body fat.
Cycling 30 minutes per day, 5 days per week at moderate pace produces 1,400 weekly calories and approximately 1.6 lb of monthly fat loss for a 155 lb person without any dietary change. Increasing from moderate to vigorous pace (MET 10.0 instead of 8.0) adds 25% more output per session, pushing the weekly total to approximately 1,750 kcal.
For the full daily energy context, use the TDEE calculator to find your maintenance calories, then calculate how 30-minute cycling sessions contribute to your weekly calorie deficit. The calories burned calculator covers all activity types alongside cycling if you mix your cardio formats across the week.
