Designer Filipe Lima’s Energysport is a device that would charge your portable devices while you are on a bike ride. Simply attach the Energysport to the hub of your bike’s wheel and as it moves, the device converts the kinetic energy of the wheel into electricity. After your bike’s ride, you can remove Energysport and use its collected energy to power your electronic gadgets. Good concept to generate renewable energy and promote bike riding at the same time.
