Schätze die Fahrradgeschwindigkeit aus der Leistung (Watt) anhand deines Gewichts, des Fahrradgewichts, der Steigung, des Untergrunds und des Winds. Physikalisch fundiert mit realistischem Rollwiderstand und CdA-Voreinstellungen.
| Kraftkomponente | Watt | % der Gesamtleistung |

Gesamtleistung = Rollwiderstand + Luftwiderstand + Erdanziehungskraft + Antriebsverlust. Konkret: P = Crr·m·g·v + ½·ρ·CdA·(v + Wind)²·v + m·g·sin(atan(Steigung))·v, geteilt durch 0.95 Antriebswirkungsgrad.
Konstanten: Luftdichte ρ = 1.225 kg/m³, g = 9.8067 m/s². Die Geschwindigkeit wird per binärer Suche ermittelt.
