Cycling Power Formula:
From: | To: |
Definition: This calculator determines the power output required for cycling based on force, speed, and system losses.
Purpose: It helps cyclists and trainers understand the power requirements for maintaining specific speeds under given conditions.
The calculator uses the formula:
Where:
Explanation: The force multiplied by velocity gives the basic power requirement, with additional losses added to account for mechanical inefficiencies.
Details: Understanding power requirements helps in training optimization, equipment selection, and performance analysis.
Tips: Enter the force in Newtons, velocity in m/s, and any system losses in Watts. All values must be ≥ 0.
Q1: What typical force values do cyclists generate?
A: Competitive cyclists typically generate 300-400N during sprints and 150-250N during sustained efforts.
Q2: How do I convert km/h to m/s?
A: Divide km/h by 3.6 (e.g., 36 km/h = 10 m/s).
Q3: What are common sources of losses?
A: Drivetrain friction (2-5%), tire rolling resistance, and bearing friction are typical loss sources.
Q4: How does this relate to cycling power meters?
A: Power meters measure the actual power output, which includes all these factors combined.
Q5: Can this calculate required power for hills?
A: Yes, but you'd need to include the gravitational force component in your total force calculation.
