The Importance of Power to Weight Ratio [P/Kg] in Cycling

It’s very useful to know your power to weight ratio as this is an important measure in cycling. In simple terms the higher your power to weight ratio the better cyclist you will be.

Maximizing your power to weight ratio is a vital part of your training and you can use the Wattbike’s power data to determine and track power to weight ratio [P/Kg].

Power to weight [P/Kg] ratio is the relationship between: Power (measured is watts [W]) and Weight (measured in kilograms [Kg])

For example if a cyclist produces a maximum minute power of 350 W during a cycling ramp test and weighs 70 Kgs the power to weight ratio [P/Kg] is expressed as: P/Kg = 350/70 = 5 Watts per kilogram of body weight

A cyclist weighing 90 Kgs achieving the same maximum minute power would have a power to weight ratio [P/Kg] of: P/Kg = 350/90 = 3.89 Watts per kilogram of body weight
