The i-Genius has a wireless motor brake with a computer-driven flywheel that generates high powers at low speeds. This makes the climbing of hills and mountains even more realistic. The i-Genius even features downhill drive. The i-Genius features PowerBack. This system converts the heat that is generated in the brake and released during the ride, into electricity that is then fed back into the power grid. This means that you are generating your own electricity. LED lights in the brake indicate the cycling speed and the power output. The communication between brake, VR interface and PC is wireless. The trainer itself has to be plugged into an electric point.
