Human Power Output While Biking: Exploring Wattage Potential

The amount of power a human can generate while biking varies based on factors such as fitness level, cycling intensity, and duration. This article delves into the wattage potential, exploring the differences between recreational cyclists, trained athletes, and professional cyclists. We will also look at a real-world example from a historical experiment that highlights the benchmarks and sustainability of power generation during cycling.

Factors Influencing Wattage Output

Several factors influence the wattage output of a human cyclist, the most notable being fitness level, cycling intensity, and duration. Recreational cyclists typically produce an average of 100 to 200 watts, while trained athletes can sustain around 200 to 400 watts for extended periods. Professional cyclists, in their prime, can reach power outputs of 400 watts or more during short bursts or sprints.

Wattage Output Over an Hour

Considering the average output over an hour, recreational cyclists often generate around 100 to 150 watt-hours in total energy. Trained athletes, on the other hand, can produce 200 to 300 watt-hours, equating to about 0.1 to 0.3 kilowatt-hours (kWh) of energy.

Real-World Experiment in Toronto

A few years ago, a fascinating experiment was conducted in Toronto where a bicycle was set up with a chain driving an electric generator. The generated current powered 100 watt light bulbs. The public was invited to pedal and witness the wattage they could produce. The highest recorded output was 400 watts by an 18-year-old male, which was unsustainable for more than a few minutes. There was no hypothesis on how long a lower level of wattage could be sustained by an average cyclist compared to an accomplished one.

Notable Cyclists and Their Wattage

Remco Evenepoel, considered one of the strongest cyclists in the pro ranks, can hold a steady output of 400 watts for an hour. This is a remarkable insight into the upper limit of wattage output for a professional competitor.

A personal account from a cyclist indicates that they can maintain an output of 258 watts for an hour with significant effort and assistance from a power meter. In contrast, their spouse can only manage around 70 watts.

Average Output in Context

Based on available data from reputable sources, a trained cyclist can produce about 400 watts of mechanical power for an hour or more. For adults of good average fitness, the output ranges from 50 to 150 watts for an hour of vigorous exercise. This translates to approximately 0.5 horsepower for a trained cyclist and between 0.07 to 0.2 horsepower for adults of average fitness.
