READ ABOUT IT BELOW:
*One of the highlights on the Audi stand at the 2012 Wörthersee was the bicycle technology concept known as the Audi e-bike Wörthersee – a sport bike that does not fit into any of the usual categories. It is neither a pedelec nor a conventional bike, but is best described as a high-end pedelec made by Audi for sport, fun and tricks. The Audi e-bike Wörthersee combines the Audi brand’s principal competences – design, ultra, connect and e-tron – and explores the limits of what is technically feasible in terms of design, lightweight construction, networking and electric mobility.
This show bike is futuristic at the very first glance – a bike for tomorrow and beyond. All its components, even the pedals, have been shaped by Audi’s designers, for instance the 26-inch wheels made from CFRP that weigh only 600 grams (1.32 lb) each and have innovative large-area blade-pattern spokes.
The Audi e-bike Wörthersee’s ultra-light carbon-fiber frame weighs only 1,600 grams (3.53 lb). It makes use of bionic principles derived from nature. Material reinforcements are needed only at the points where loads actually occur. The swinging arm for the rear wheel is also made of CFRP. All in all, the Audi e-bike Wörthersee represents the full extent of the brand’s expertise in ultra-lightweight design.
The rear wheel is driven by a chain. The electric motor is a permanent magnet synchronous machine; it is located at the lowest point on the frame and drives the bottom bracket shaft directly. Maximum torque at the rear wheel is in the region of 250 Nm (184.39 lb-ft). Peak output from the electric motor is 2.3 kW – a new top value on the e-bike scene. The complete bicycle weighs only 21 kg (46.30 lb), equivalent to a power-weight ratio of 9 kg (19.84 lb) per kilowatt, or 7 kg (15.43 lb) per horsepower – another record-breaking value.
The lithium-ion battery is housed in the frame; it weighs about 5 kg (11.02 lb) and operates at a voltage of 48 V. Its capacity is 530 Wh and it can be fully recharged from a 230 V supply in two and a half hours. As an alternative it can be easily detached from the bike and replaced by a recharged battery.
The rider of the Audi e-bike Wörthersee can choose between five programs; these either support use of the pedals or permit electric-only travel.
In the ‘Pure’ mode the rider only propels the bike by means of the pedals. In the ‘Pedelec’ mode the rider is assisted by the electric motor; a top speed of up to 80 km/h (50 mph) can be reached and the action radius is between 50 and 70 kilometers (31 and 44 miles). In the ‘eGrip’ program the Audi e-bike Wörthersee can be ridden with the electric motor providing all the necessary power; in this case at speeds up to 50 km/h (31 mph). The rider controls the power output from the electric motor at a twistgrip and can configure it at the on-board computer.
