Power-to-weight ratio is a measurement of actual performance of any engine or power source. It is also used as a measurement of performance of a vehicle as a whole, with the engine’s power output being divided by the weight (or mass) of the vehicle, to give a metric that is independent of the vehicle’s size.

For example, an 80kg rider with a maximum sustainable power output of 280 watts has a power-to-weight ratio of 3.5 watts per kilo (commonly abbreviated as 3.5W/kg or 3.5W. kg-1).
What is a high power-to-weight ratio?
The power-to-weight ratio represents the ratio between a vehicle’s power and its total weight. The higher the PWR, the faster the vehicle will accelerate. It is for this reason that motorbikes accelerate quicker than most cars.
