Pedal power is the transfer of energy from a human source through the use of a foot pedal and crank system.

This technology is most commonly used for transportation and has been used to propel bicycles for over a hundred years. Less commonly pedal power is used to power agricultural and hand tools and even to generate electricity. Some applications include pedal powered laptops, pedal powered grinders and pedal powered water wells. Development projects in many countries currently transform used bicycles into pedal powered tools for sustainable development.
