What This Calculator Does

Estimate required cycling power from speed, rider mass, and road grade.

It combines Speed, Rider + Bike Mass, Road Grade to estimate Estimated Power, Rolling Resistance, Climbing.

Formula & Method

Core equations: Cycling power: P=(F_{roll}+F_{aero}+F_{grade})v where F_{roll}=C_{rr}mg, F_{aero}=\tfrac12\rho C_dAv^2, F_{grade}=mg\sin\theta.

Notation used in the formulas: R = Estimated Power; x_{1} = Speed; x_{2} = Rider + Bike Mass; x_{3} = Road Grade.

Method summary: inputs are normalized to consistent units, core equations are evaluated, then secondary values are derived and rounded for display.

Use this calculator for quick scenario analysis. Start with baseline values, change one driver at a time, and compare how sensitive the results are to each input shown above.

Inputs Used

Speed: Used directly in the calculation.
Rider + Bike Mass: Used directly in the calculation.
Road Grade: Used directly in the calculation.
