How does cycle pedal Generator produced electricity?
the pedals drive the wheel, the wheel drive an electrical generator.2 possibilities for the wheel to drive the generator:-the wheel does not have a tire: a belt goes in the rim and drive a puley on the shaft of the generator.-the wheel has a tire: there is a drive roller on the shaft of the generator. the drive roller is pressed on the tire.The generator can be of any kind. They are commonly car alternator or permanent magnet dc motor, but you can also drive an alternative current squirel cage generator. Depending on the chosen generator, you have to use an electric circuit appropriate for the generator.
