Cycling Wattage Calculator
Approximate required power using speed, grade, and aero drag
📖 Cycling Wattage Calculator
This physics-based estimate includes gravitational, rolling, and aerodynamic forces. Input rider + bike mass, CdA, rolling resistance, speed, and grade.
📊 Result
💡 Tips & Information
- Lower CdA (aero position) dramatically cuts power needs at high speed.
- Rolling resistance depends on tire and surface; adjust Crr accordingly.
- Downhill grades (negative %) reduce gravity power but aero drag remains.
