The radical-looking Audi e-bike Wörthersee prototype is quite something. It combines electric drive with muscle power, reportedly producing a top speed of 80 km/h using both. The rider can choose from a total of five cycling modes – pure muscle power, electric motor alone, or pedalling with support from the electric motor. The lithium-ion battery, incorporated into the frame, needs 2,5 hours to fully charge.
Carbon fibre-reinforced polymer is used for the frame and the swinging arm that holds the back wheel, and the same material is used for the 26-inch wheels, which feature an innovative “Audi ultra blade” design with broad flat spokes for optimised transmission of pedal power.
For extreme tricks and stunts, the seat can be lowered to run flush with the frame itself. At the press of a button, the seat rises up, allowing the rider to adopt a comfortable position. Cycling modes and many other functions can be set using the onboard touchscreen computer. The rider’s smartphone hooks up by WLAN to the computer, so that when he starts cycling, for example, the immobiliser is deactivated. Video clips recorded via an in-helmet camera are uploaded to the Internet in real time via the smartphone.
