Calculate your power output easily with the Stationary Bike Watts Calculator. Find out how watts relate to speed, calories burned, and distance.
Cycling on a stationary bike is one of the best ways to improve endurance, burn calories, and track power output. But have you ever wondered how much power you generate while cycling? Our Stationary Bike Watts Calculator helps you estimate your power output based on resistance, cadence, and duration. Whether you're training for fitness, comparing your performance, or optimizing your workout, this calculator provides an accurate wattage estimation.
Cyclists often ask, "What is a good wattage for a stationary bike?", or "How many watts can a stationary bike produce?" This guide will not only help you understand your power output but also explain how watts relate to speed and energy expenditure.
Using the Stationary Bike Watts Calculator is simple:
This calculator is based on a widely used formula for estimating power output on a stationary bike.
The formula for calculating power output (watts) is:
Power (W) = Resistance (kg) × Cadence (RPM) × 0.981
To calculate the distance traveled on a stationary bike, use:
Distance (km) = (Cadence × Duration × 6) / 1000
If you want the distance in miles:
Distance (mi) = Distance (km) × 0.621371
For calories burned, the formula is:
Calories = (Power × Duration × 60) / (4184 × 0.24)
Cyclists often ask: "How fast is 200 watts on a bike in mph?" or "Watts to km/h conversion?" While stationary bikes don't measure speed like road bikes, you can estimate speed using a general approximation:
| Power Output (Watts) | Estimated Speed (km/h) | Estimated Speed (mph) |
|---|---|---|
| 50 W | 15 km/h | 9.3 mph |
| 100 W | 22 km/h | 13.7 mph |
| 150 W | 26 km/h | 16.1 mph |
| 200 W | 30 km/h | 18.6 mph |
| 250 W | 35 km/h | 21.7 mph |
| 300 W | 40 km/h | 24.8 mph |
A good wattage depends on your fitness level:
FTP (Functional Threshold Power) measures sustained power over an hour. 250 watts is a strong FTP for recreational riders and excellent for fitness enthusiasts.
Most commercial stationary bikes allow you to generate between 50 and 500 watts, depending on resistance and cadence.
The Stationary Bike Watts Calculator is a great tool for tracking your power output and improving your indoor cycling workouts. By understanding how watts relate to distance, speed, and calories burned, you can set fitness goals and optimize training sessions. Whether you're a casual rider or a serious cyclist, monitoring your wattage helps improve endurance and efficiency.
Use the formula: Power (W) = Resistance × Cadence × 0.981. Input your values into the calculator to get an instant result.
While this calculator is designed for stationary bikes, it can give an approximate idea of power output for MTB riders using resistance and cadence.
Higher wattage indicates better power output, but endurance, technique, and cardiovascular fitness also play key roles.
Speed depends on terrain, weight, and aerodynamics, but the table above provides a general estimate.
For road cycling, wind resistance and incline affect wattage, so an advanced power meter would be more accurate.
