This bike cadence and speed calculator will help you to estimate what is your speed when cadence is known or the other way round - determines the cadence if you know your speed. Choose your chainring, cog, wheel size, tire size and speed or cadence, and we will tell you the rest. Whether you are looking for a cadence calculator or bike speed calculator, our flexible tool is a good choice.
Cadence is the rate at which a cyclist is turning the pedals, in rpm unit (revolutions per minute). There are many cadence sensor on the markets nowadays, but you don't need that gadget for a rough estimate. The only thing that approach requires is a watch, timer or other time measuring device. You can do it in different ways:
Remember that the longer the period is, the better the cadence estimate obtained. Practice makes permanent, and after some time you can make a good guess of your cadence.
Have you ever wondered what best cyclist cadence is when they are taking part in Tour de France, e.g., chasing the peloton ? Or maybe you want to have a rough idea of how fast you were going on your bike trip? Let's check it:
speed = π * (diameter + (2 * tire_size)) * (chainring/cog) * cadence
cadence = speed / (π * (diameter + (2 * tire_size)) * (chainring/cog))
If you want to determine average speed based on distance and time, use our speed calculator.
