Pedal-powered devices are machines that use human pedaling as a source of energy. These devices convert the mechanical energy generated by pedaling into various forms of power, such as electricity or kinetic energy. Common examples include bicycles, pedal generators, and exercise bikes. These devices promote sustainability by reducing reliance on fossil fuels and encouraging physical activity. They can be used for various purposes, including charging batteries, powering small appliances, or providing a fun way to exercise. Pedal-powered technology is increasingly popular in eco-friendly initiatives and community projects.
