How many people pedaling bikes does it take to power an electric shower?
About 75 people pedalingAn electric shower needs about 7,500 W, and a rider makes about 100 W.
It takes about 75 people pedaling.
How we worked it out
An electric shower needs about 7,500 W, and a rider makes about 100 W. Each rider keeps up a steady 100 watts, like a brisk ride. Real life adds a little friction and waste, so treat the number as a solid ballpark rather than a lab result. The constants behind every experiment are on the science page.
Watch it happen
This was one of the five experiments in It Took #11. In the game you guess first, then the experiment plays out with your number: too few and it fails, too many and it overshoots.
