A bicycle-powered generator is a device that converts the mechanical energy produced by pedaling a bicycle into electrical energy. This is typically achieved by connecting the bicycle's rear wheel to a generator, which spins as the wheel turns. The generated electricity can be used to power small devices, charge batteries, or even provide energy for lighting. These generators are often used in off-grid situations, during emergencies, or for educational purposes to demonstrate renewable energy concepts. They promote physical activity while providing a sustainable energy source, making them an eco-friendly alternative to traditional power generation methods.
