Estimate spin-bike console-equivalent distance from speed and time, reverse-solve ride time, or model distance from cadence, circumference, and drive ratio.
Spin Bike Distance Formula
Use displayed speed and time for distance, a target distance and displayed speed for ride time, or bike-specific cadence and geometry for modeled distance. Cadence-mode meters = crank RPM × minutes × effective flywheel circumference (m) × flywheel revolutions per crank revolution.
| Method | Inputs | Estimated distance |
|---|---|---|
| Displayed-speed distance | 30 minutes at 12 mph | 6.00 miles |
| Displayed-speed distance | 45 minutes at 14 mph | 10.50 miles |
| Illustrative cadence model | 80 crank RPM for 45 minutes; effective circumference 1.6 m × drive ratio 1 | 5.76 km (3.58 miles) |
| Illustrative cadence model | 90 crank RPM for 60 minutes; effective circumference 1.6 m × drive ratio 1 | 8.64 km (5.37 miles) |
The cadence examples use illustrative geometry, not universal bike defaults. A stationary bike does not travel over ground. Indoor-bike consoles use different flywheel and resistance models, so compare sessions with the same bike and method whenever possible.
The following formula is used to calculate the Spin Bike Distance.
- Where SBD is the Spin Bike Distance (miles)
- S is the average spin bike speed (MPH)
- T is the total time of exercise (min)
To calculate spin bike distance, divide the average spin bike speed by 60, then multiply by the total exercise time.
How to Calculate Spin Bike Distance?
The following example problems outline how to calculate Spin Bike Distance.
Example Problem #1:
- First, determine the average spin bike speed (MPH).
- The average spin bike speed (MPH) is given as 35.
- Next, determine the total time of exercise (min).
- The total time of exercise (min) is provided as 40.
- Finally, calculate the Spin Bike Distance using the equation above:
SBD = S / 60 * T
The values given above are inserted into the equation below and the solution is calculated:
SBD = 35 / 60 * 40 = 23.33 (miles)
Example Problem #2:
For this problem, the variables needed are provided below:
average spin bike speed (MPH) = 40
total time of exercise (min) = 20
This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.
SBD = S / 60 * T = ?
