One of the major problems of our country is the limited supply of electricity. And as a researcher we created a simple way on how we charge electrical energy from huma/mechanical energy or pedal power with the use of our Bicycle Charger. A Pedal Powered generator provides a method of generating electricity by means of a modified exercise bike for use in energy storage and running portable devices. Human.mechanical energy is converted by a belt-liked cloth to a bike dick brake. The energy created
