Power Meter

A bicycle power meter is a device that measures the power (expressed in watts) a cyclist applies to the pedals. This tool is very useful for improving performance and optimizing cycling training. Here's a brief description of how it works. Sensors : The power meter uses electronic sensors called strain gauges, which measure the force exerted on the pedals. These sensors detect small deformations in the materials of the pedals or cranks. Power calculation : The data collected by the sensors is processed by a processor that calculates the power output in watts. Power is the product of the force exerted and the angular rotational speed of the cranks.
