If you're cycling uphill, you need to overcome the force of gravity. Naturally, if you're going downhill, gravity will actually help you, making you accelerate without any additional effort. Cycling wattage is the power you produce with your legs to get your bike going (and, preferably, going fast). You can think of it as the ultimate measure of your biking skills: the more power you can produce, the better cyclist you are.

Our cycling wattage calculator is based on the model described in detail in the paper "What is slowing me down? Estimation of rolling resistances during cycling". It assumes that the power you produce is equal to the sum of resistances you need to overcome, multiplied by your speed. Additionally, we take power losses into consideration. g g g – Gravitational acceleration, equal to 9.80665 m / s 2 9.80665\ \text{m}/\text{s} The cycling power is measured in watts. One watt corresponds to one joule of energy produced every second.
