Calculate calories burned cycling based on distance, speed, duration, weight, terrain, and bike type using MET-based formulas.
Cycling is one of the most efficient calorie-burning exercises, offering a low-impact way to torch significant energy while being gentle on joints. The number of calories you burn while biking depends on multiple factors including your body weight, riding speed, duration, terrain, wind conditions, and the type of bicycle you're using. Understanding this relationship helps you plan workouts for weight management and optimize your fueling strategy for longer rides.
At a basic level, cycling calorie expenditure is calculated using MET (Metabolic Equivalent of Task) values. Light cycling at 10 mph has a MET of about 6.8, moderate cycling at 14 mph is about 10, and vigorous road cycling at 18+ mph reaches METs of 12-16. Mountain biking adds terrain resistance that pushes MET values even higher.
This calculator goes beyond simple estimates by accounting for terrain type, gradient, wind resistance, and bike type. Whether you're a casual commuter, weekend warrior, or competitive cyclist, it provides detailed calorie expenditure data to support your training and nutrition goals.
Accurate cycling calorie data helps you fuel properly for rides, plan weight management goals, and understand the fitness benefits of your cycling habit.

Calories = MET × 3.5 × Weight(kg) / 200 × Duration(min). MET by speed: 10 mph = 6.8, 12 mph = 8.0, 14 mph = 10.0, 16 mph = 12.0, 18 mph = 13.5, 20+ mph = 15.8. Terrain multiplier: Flat = 1.0, Rolling hills = 1.15, Mountain = 1.4. Headwind adds ~10-20%.
Result: ~680 calories burned
A 170 lb cyclist riding at 15 mph on rolling terrain for one hour burns approximately 680 calories. The hilly terrain adds about 15% over flat riding at the same speed.
The three primary factors are body weight, riding intensity (speed), and duration. Secondary factors include terrain profile (climbing adds significantly), wind conditions, rolling resistance (tire type and pressure), aerodynamic position, and altitude. At 5,000+ feet elevation, the thinner air slightly reduces aerodynamic drag but also reduces oxygen availability, shifting the metabolic cost.
One pound of fat contains approximately 3,500 calories. A 160 lb person cycling at moderate intensity burns about 500-600 calories per hour. To lose one pound per week from cycling alone (without dietary changes), you'd need to ride about 6 hours per week. Combining cycling with moderate caloric restriction (250-500 cal/day deficit) makes weight loss more achievable and sustainable.
For cyclists with power meters, calorie estimation is much more accurate: kJ of work output closely approximates kcal burned (due to ~25% mechanical efficiency). Without a power meter, MET-based calculations provide reasonable estimates but can vary by ±15-25% depending on individual fitness, drafting, and bike setup. Heart rate-based estimates fall between these in accuracy.
A 150 lb person burns approximately 250-350 calories in 30 minutes of moderate cycling (12-14 mph). A 200 lb person burns 340-470 calories in the same time.
Yes, significantly. Mountain biking burns 30-50% more calories than road biking at a comparable perceived effort due to terrain resistance, constant acceleration/deceleration, and upper body involvement.
Cycling is excellent for weight loss. It burns substantial calories, is sustainable long-term, and is easy on joints. A consistent 30-minute daily ride can contribute to losing 1-2 lbs per month when combined with proper nutrition.
Yes, e-bike riders still burn about 40-60% of the calories of conventional cyclists. The pedal assist reduces effort but doesn't eliminate it, and riders often go further and ride more frequently.
Heavier riders burn more total calories because they're moving more mass. However, power-to-weight ratio matters more for speed. A 200 lb rider burns roughly 30% more calories than a 150 lb rider at the same speed.
For rides over 60-90 minutes, consuming 30-60g of carbs per hour helps maintain performance. For rides over 2.5 hours, aim for 60-90g per hour. This calculator shows the calorie deficit that needs fueling.
