Definition:
Watts represent the unit of power in cycling, describing how much energy a rider produces while pedaling. In simple terms, it shows the rate at which work is being done on the bike.
Why it matters:
- Watts provide an objective measurement of cycling performance that goes beyond speed or heart rate.
- They help riders structure effective training programs and monitor progress over time.
- Power data in watts is used in races, training apps, and professional coaching to optimize real-world cycling performance.
How it’s measured / used / recognized:
Watts are measured using a power meter installed in pedals, crank arms, or wheel hubs. Training platforms and bike computers display this data in real time, helping riders adjust intensity during workouts or races.
Related terms:
- Functional Threshold Power (FTP)
- Power Meter
- Cadence
Example in practice:
A rider maintaining 250 watts on a climb can compare this effort across different days, regardless of wind or gradient, making watts one of the most reliable measures of cycling performance.
