Can I use this calculator if I only know my gear ratio and speed?

Yes, you can input the chainring and sprocket teeth numbers directly, then set tire thickness, rim diameter, and speed to get your cadence.

Does the tool support both metric and imperial units?

Yes, a measurement system picker lets you switch between kilometers per hour and miles per hour for the speed input.

What if my tire size is listed in inches rather than millimeters?

The site includes guidance on converting inch-based tire markings to the international ISO 5775 standard before entering the value.

Is the cadence calculation affected by wheel size or only by gear ratio?

Both wheel size (rim diameter plus tire thickness) and gear ratio (chainring versus sprocket teeth) factor into the cadence result.

About this tool

What Bike Cadence Calculator does

BikeCalc’s Cadence Calculator is an interactive web tool that lets cyclists determine their pedaling rate by entering specific bike measurements. Users input chainring teeth, sprocket teeth, tire thickness, rim diameter, and desired speed to see the resulting cadence. The site provides step-by-step instructions and adjustable sliders or pickers for each parameter, with results updating in real time. A measurement system toggle converts speed between kilometers per hour and miles per hour. The calculator is freely accessible online and has been a popular resource for cyclists since 2009.

Step by step

How to use the BikeCalc Bike Cadence Calculator

1
Select the number of teeth on your front chainring using the chainrings picker
2
Select the number of teeth on your rear sprocket using the sprockets picker
3
Enter your rear tire thickness in millimeters using the tire thickness picker
4
Input your rim diameter in millimeters using the rim diameter picker
5
Drag the speed slider or choose measurement system to set your desired speed and units
