How Does A Bike Power Meter Work? (Solved)

Power meters typically work by measuring the force on a component (pedal axle, crank arm, spider) using strain gauges. They then convert this to power by multiplying it by the angular velocity (or cadence) of that component. As we’ve already covered, power is measured in watts.

What is the best power meter for a bicycle?
