Cycling Power Calculator

This tool calculates the power in watts needed to cycle at a specific speed. It considers rider and bike weight, wind speed, and road gradient.

1. 1

   Enter Weights

   Input your weight and bike/equipment weight

2. 2

   Enter Speed

   Input target speed and gradient

3. 3

   Calculate Power

   The tool calculates required power in watts

• 1

  Power-to-weight ratio (W/kg) is more important than absolute power

• 2

  3-4 W/kg is good for amateurs, 5-6 for professionals

• 3

  Air resistance increases quadratically with speed

• 4

  Aerodynamic positioning significantly reduces resistance

• Ignoring the effect of wind on actual performance

• Focusing on absolute power rather than relative power

• Not accounting for altitude and atmospheric pressure

• Comparing your power without considering test conditions
