Cadence to Speed Calculator
Calculate cycling speed based on cadence, gear ratio and wheel size
About this calculator
The Cadence to Speed Calculator helps cyclists determine their riding speed based on pedaling cadence (RPM), gear ratio, and wheel size. This tool is essential for optimizing performance, planning training sessions, and understanding how different gear combinations affect your speed. Whether you're a competitive cyclist fine-tuning your setup or a recreational rider curious about your pace, this calculator provides accurate speed predictions to improve your cycling efficiency and strategy.
How to use
Enter your pedaling cadence in revolutions per minute (RPM), input your bike's gear ratio (chainring teeth divided by cassette teeth), and specify your wheel size in inches or millimeters. The calculator will instantly compute your theoretical speed, helping you optimize gear selection and cadence for different riding conditions.
Frequently asked questions
What is a good cycling cadence for beginners?
Most beginners should aim for 70-90 RPM. This range provides good efficiency while building leg strength and cardiovascular fitness without overstraining muscles.
How do I calculate my bike's gear ratio?
Divide the number of teeth on your chainring by the teeth on your rear cassette cog. For example, 50 teeth front ÷ 25 teeth rear = 2.0 gear ratio.
Does wheel size significantly affect cycling speed?
Yes, larger wheels cover more distance per revolution. A 700c wheel travels further than a 26-inch wheel at the same cadence and gear ratio, resulting in higher speeds.
