Audi has this month unveiled a new bike they have created for “sport, fun and tricks” says Audi, in the form of the Audi e-bike Wörthersee. The Audi e-bike Wörthersee has been created by Audi to investigate what is possible for a bike in terms of design, lightweight construction, networking and electric mobility.
All the components within Audi e-bike Wörthersee have been designed and custom created by Audi engineers. For example the 26-inch wheels are constructed from CFRP and incorporate large-area blade-pattern spokes, allowing them to weigh just 600 grams each.
The frame of the bike is constructed from carbon-fiber and weighs just 1.6kg, and its power is provided by an electric motor which is a permanent magnet synchronous machine The engine is located at the lowest point on the frame and drives the bottom bracket shaft directly, providing maximum torque of approx. 250 Nm (184.39 lb-ft), with max output from the electric motor of around 2.3 kW.
Excluding the battery, 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. For more information on the concept bike and what its capable of jump over to the Derestricted blog.
