Ducatis aren’t the only two-wheelers under the Audi corporate umbrella these days. The German company recently unveiled its concept Worthersee e-bike, to which Audi applied its vast experience with high-tech composites, electronics and lithium-ion batteries. This innovative machine can operate solely on muscle power through a nine-speed bicycle transmission, rely only on its 2.3-kilowatt electric motor (with a 0.53 kW-h battery pack) or act as a human/electric hybrid.
Weighing a scant 57 pounds, the Worthersee can reach a maximum speed of 50 mph when the motor is aided by people propulsion.
