How To Make A Pedal-Powered Sound System
Pedal power uses the most powerful muscles in the body: the quads, hamstrings, and calves. When pedalling in a circular motion at 60-80 revolutions per minute, with the use of toe clips, almost every muscle in the human legs can be used to make energy. Ninety-five percent of the exertion put into pedal power is converted into energy. The average rider at a continuous road speed of 12 miles per hour can produce a quarter horsepower, or enoughenergy to light two, one hundred-watt light bulbs.
