Can I use this calculator with metric and imperial measurements mixed together?

Yes, the tool accepts rim size, tire size, and other parameters in either millimeters or inches, allowing you to mix units as needed.

What cadence range does the reference table cover?

The reference table lists cadence values from 10 RPM up to 200 RPM, showing the corresponding speed in both km/h and mph for your bike setup.

Do I need to know my exact wheel diameter to get accurate results?

You can enter either the rim diameter or the combined wheel and tire diameter; the calculator uses those values to compute speed from cadence.

Is the cadence-to-speed conversion instant, or do I need to press a button?

The calculator automatically computes the corresponding speed or cadence as you adjust inputs; no separate calculate button is required.

About this tool

What Bike Cadence Calculator does

The SportCalculators Bike Cadence Calculator converts between pedal cadence and cycling speed using your bike’s specific geometry. Enter your rim size, tire dimensions, chainring teeth, and cog teeth to see how different RPMs translate into forward speed, with results shown in both kilometers per hour and miles per hour. The output includes an interactive cadence reference table that lists speed values across a range of cadences based on your entered setup.

Step by step

How to use the SportCalculators Bike Cadence Calculator

1
Enter your bike’s rim size in millimeters or inches
2
Input the tire size in millimeters or inches
3
Specify the number of teeth on your front chainring and rear cog
4
Input your desired cadence in RPM or target speed, then select km/h or mph for the speed unit
5
View the auto-calculated corresponding speed or cadence and scroll the reference table for a full range of cadence values

Is it right for you

Best for

Cyclists who want to fine-tune their gear ratios and understand how cadence choices affect speed, especially those comparing units or building a custom wheel setup.

Limitations

The reference table currently shows NaN values, indicating the calculator may not yet process inputs
No explicit unit conversion toggle beyond the km/h/mph selector
Output depends on accurate manual entry of wheel and gear dimensions
