Definition:
A power meter is a device used in cycling to measure the rider’s power output in watts. It provides accurate, real-time data on how much energy a cyclist is producing during training or racing.
Why it matters:
- Power meters give cyclists an objective way to track performance, unaffected by wind, terrain, or fatigue.
- They allow precise training based on power zones, helping athletes improve endurance and speed efficiently.
- Power data is essential for coaches, competitive riders, and amateurs who want to compare efforts across different rides and conditions.
How it’s measured / used / recognized:
Power meters are typically integrated into pedals, crank arms, or wheel hubs. They measure the torque applied by the rider and convert it into watts, which are displayed on a cycling computer or training app.

Example in practice:
During interval training, a cyclist may target 300 watts for short efforts and recover at 150 watts, using the power meter to control intensity and avoid overtraining.
