🚴 Cycling Speed Estimator
Rough speed estimate from power and weight
About this calculator
On flat roads, cycling speed is mostly a battle between your power output and aerodynamic drag, which is why power meters are so popular. This calculator gives a rough speed estimate from your watts and body weight using a simplified model. It is a ballpark figure, not a wind-tunnel result.
Tip: Position matters more than weight on the flats. Dropping into the drops can be worth 20 watts or more at the same effort.
