A Pedal Generator is commonly called a Pedgen.
It seems to be natural to want to make power using your own body.
However the human body is very limited in it's capability to make power.
A physically fit athlete can produce about 200 watts for a short time
The average man can produce
150 watts for 1 to 5 minutes
100 watts for 15 to 30 minutes
50-80 watts continuously
It helps to have some cooling because your body will also generate quite a lot of heat.
Lots of us have made Pedal Generators. They are represented in the following links . . .
