How much horsepower does a bicycle have?
The basic principles about bicycles are well stated, middle school physics is sufficient.
The thrust of a bicycle = pedaling force x number of flywheel teeth x crank length/chain disk teeth x diameter of the main wheel;
The resistance of a bicycle is primarily wind resistance and grade resistance. Wind resistance is proportional to the windward area, wind resistance factor, air density, and the square of speed, and is the greatest resistance on a flat road, accounting for more than 80% of all resistance at high speeds.
People's power not only varies from person to person, the same person range is also very large, long time and short time difference of several times. The average person is about one or two hundred watts for short periods.
