How Many Calories Burned 1 Hour Indoor Cycling? | Ride Facts

Indoor Cycling Calories Per Hour—What Changes The Number

Calories per hour on the bike depend on two things you can’t separate: how much you weigh and how hard the work feels. The metric that ties both together is the “metabolic equivalent,” or MET. One MET equals about 1 kcal per kilogram per hour at rest, and activity METs stack on top of that during exercise (CDC: METs).

Indoor bikes let you raise power with resistance and cadence. As intensity rises, METs rise, so the burn climbs in step. A steady endurance spin sits around 6–7 METs. HIIT blocks or strong climbs can push past 10 METs, and very tough sets go even higher in short bursts, matching values listed for stationary cycling by watt level in the Adult Compendium of Physical Activities (Compendium: stationary METs).

Quick Reference: Calories Per Hour By Weight And Effort

The table below uses standard MET math (kcal/hour ≈ MET × 1.05 × body weight in kg) to give practical ranges for a steady session and a tougher ride. Pick the row closest to you, then adjust for how the workout felt.

Body Weight	Moderate Effort (~6.8 MET)	Vigorous Effort (~10.3 MET)
55 kg (121 lb)	~393 kcal/hour	~595 kcal/hour
68 kg (150 lb)	~486 kcal/hour	~735 kcal/hour
82 kg (180 lb)	~585 kcal/hour	~887 kcal/hour
100 kg (220 lb)	~714 kcal/hour	~1,082 kcal/hour

What “Moderate” And “Vigorous” Feel Like

Use the talk test as a quick cue. In a moderate block, you can speak in short sentences. In a vigorous block, speech breaks into single words. Many bike consoles also show watts and heart rate zones, which map well to how hard the work feels.

How To Estimate Your Personal Burn

You can ballpark your hourly number with three steps: pick a MET that matches the ride, multiply by your weight in kilograms, and include the 1.05 factor (the constant from the MET formula). The result lands near what you’ll see for a typical hour at that intensity.

Step 1: Match Effort To A MET

Here’s a simple guide you can use right away:

• Recovery spin: ~4 MET (light resistance, easy breathing)
• Endurance pace: ~6–7 MET (steady, sustainable)
• Spin/HIIT peaks: ~9–11 MET (hard bursts, breathless)

If your bike shows watts, you can use watt ranges listed by the Compendium (e.g., 126–150 watts ≈ 8.0 MET; 151–199 watts ≈ 10.3 MET). This ties your output directly to an expected burn.

Step 2: Do The Quick Math

Formula: calories per hour ≈ MET × 1.05 × body weight (kg). A 68-kg rider at 7 MET sits near 7 × 1.05 × 68 ≈ 500 kcal in an hour. Bump effort to 10.8 MET during a hard interval set, and the same rider lands near 770 kcal in that hour.

Step 3: Calibrate With Your Data

Heart rate trends, average watts, and how fresh you feel at the end all refine the estimate. If the ride felt easy, use the lower MET for that style. If your average watts were up and the last 10 minutes felt spicy, slide to the higher MET.

Factors That Swing The Number

Body Weight

Heavier riders expend more energy at the same MET. That’s why two people in the same class can have very different totals even with identical programs.

Resistance And Watts

More load equals more work. A small turn of the knob that lifts watts by 20–30 through the hour can add triple-digit calories to the final count.

Cadence And Technique

Spinning the pedals fast without control wastes energy that doesn’t move the flywheel as well. A smooth stroke at a cadence you can hold keeps power steady and keeps form clean.

Ride Structure

Steady endurance blocks hold a narrow band of METs. Intervals push METs up during work sets and drop them down for recovery; the average across the hour often lands in the mid to upper range.

Room Setup And Bike Fit

Fan, airflow, and a tidy bike fit help you hold output longer. Poor cooling and an awkward saddle height sap effort and trim the total.

How This Helps With Energy Balance

Seeing an honest per-hour range makes daily planning easier. Your snack plan, portion size, and recovery shake fit better once you’ve set your daily calorie needs. The number also keeps expectations in check: strong rides help, but food choices still drive the scale.

Use Heart Rate And Power To Guide Effort

If your studio bike pairs with a strap, keep most of the hour in a steady zone and sprinkle in short bursts. As conditioning grows, the same heart rate yields higher watts, and the burn rises without extra strain.

Simple Zone Targets

• Endurance: 65–75% HRmax, smooth cadence
• Tempo: 75–85% HRmax, strong but stable
• Bursts: 85–95% HRmax, 30–90 seconds, full recoveries

Match resistance to keep form neat during the last 20% of each work set. If cadence falls apart, it’s a sign to dial it back a touch.

Sample Hour Plans With Estimates

These templates show how a typical hour might shake out. Numbers use the same MET math for a 68-kg rider. If you’re lighter or heavier, scale with the formula from earlier.

Ride Type (60 Minutes)	Avg Intensity (MET)	Estimated Calories (68 kg)
Recovery Spin + Drills	~4.0	~286 kcal
Endurance Base (steady)	~7.0	~500 kcal
HIIT: 10×1-min Hard, Full Rest	~10.8	~771 kcal

How To Raise Burn Safely

Nudge Resistance, Not Just RPM

Add a small turn to the knob during long sets instead of only spinning faster. This keeps power steady and joints happy.

Use Short, Crisp Bursts

Ten to fifteen one-minute reps at a strong pace can pull the hour up. Keep the recoveries easy to make the next rep count.

Build Progress Week To Week

Pick one lever to bump each week: total minutes, average watts, or the number of work intervals. Small steps stack without burning you out.

How Consoles And Apps Estimate Calories

Most bikes use MET tables, your weight entry, and sometimes heart rate or power. Some consoles assume a default weight, which skews totals. Set your weight, and if the bike shows watts, trust that number for comparisons across sessions.

Harvard Health’s broad chart for stationary cycling lines up well with the ranges above, showing that a mid-size rider lands near 250–260 calories per 30 minutes at a steady pace and much higher during tougher blocks (Harvard: 30-minute chart).

Putting It All Together For Your Next Ride

Plan the hour with intention. Warm up, settle into a steady band, then pepper in short pushes. Watch watts and breathing, not just speed. A smooth cadence, a fan blowing, and a bottle in reach make the whole session feel better.
