Average speed assumes a steady effort; real rides vary with wind, hills, drafting and stops. A handy planning estimate, not a guarantee.
Use this free bike calculator to work out cycling distance, time or average speed. Enter any two and it finds the third — handy for planning rides, pacing efforts or checking your average speed.
What this bike calculator does
A bike calculator links the three numbers every cyclist cares about — distance, time and average speed. Fill in any two and it calculates the third, then shows all three plus your pace per km or mile. Switch between metric and imperial units.
How it works
Speed = distance ÷ time
Time = distance ÷ speed
Distance = speed × time
Ride 40 km in 1h30m and your average speed is about 26.7 km/h. Want to know how long 40 km takes at 27 km/h? Around 1h29m. Planning a 2-hour ride at 27 km/h? That’s 54 km.
