Designer Nicolás A. Jara presents the contemporary version of the rickshaw as an answer to pollution. Titled the “POTENZA”, the human energy demonstrator comes with a stylish and retractable windshield that adds to the aesthetics. This ingenious four-wheeler runs on kinetic energy transformed from human power, leaving our planet emission free. The POTENZA not only woos the world with its good looks, but will also help you look good. Driving the green vehicle will require you to perform physical exercise, which in turn helps you keep in good shape.
