About this calculator

The speed by cadence calculator helps cyclists estimate average speed based on cadence (revolutions per minute) and bike development. Development is the distance traveled per pedal rotation, calculated using the wheel size and gear ratio. This tool is useful for training planning, gear adjustments, or understanding cadence's impact on speed.

The formula used is v = (cadence × development) / 60, where cadence (in rpm) is multiplied by development (in meters per rotation) and divided by 60 to convert minutes to hours. For example, with 90 rpm and a 5-meter development, speed would be (90 × 5) / 60 = 7.5 km/h. Development varies with gear ratios and wheel size, requiring precise adjustments for accurate results.

Use this calculator during training to compare gear efficiency, set optimal cadence for energy saving, or plan routes with sustainable speeds. However, remember that wind, slope, and air resistance affect actual speed. Accurately measuring development is crucial for reliable calculations.

For better results, verify gears and wheel size precisely. Riders without measurement tools can use online development calculators. Avoid excessively high or low cadences, as they may reduce efficiency and increase injury risk.

Frequently asked questions

What is development in cycling?

Development is the distance a bicycle travels per pedal rotation, calculated using the gear ratio and wheel diameter.

How to calculate development?

Use the formula: development = (chainring teeth / cog teeth) × π × wheel diameter.

Does cadence directly affect speed?

Yes, but speed also depends on development. The same cadence in larger gears results in higher speeds.

Why divide by 60 in the formula?

Dividing by 60 converts minutes to hours to express speed in km/h or m/s.

Can I use this calculator for track training?

Yes, provided development and cadence values are measured accurately.
