Re: Audi e-bike: A bicycle that runs at 80 kmph Some more info on this one, courtesy Zigwheels:
The lithium-ion battery is incorporated into the frame and needs 2.5 hours to fully charge and is easily replaceable.
The frame and the swinging arm that holds the back wheel are made of carbon fibre-reinforced polymer (CFRP). The same material is used for the 26” wheels, which feature broad flat spokes for an optimized transmission of pedal power.
At the press of a button, the seat then rises up and the biker can adopt a comfortable position. The electric motor is located at the lowest point on the frame and drives the bottom bracket shaft directly. The maximum torque delivered to the rear wheel is 250Nm. The electric motor generates a maximum output of around 3bhp. The complete bike excluding electrical components weighs 11kg.
Cycling modes and other functions can be set using the touchscreen on-bike computer. The computer on the bike can connect to the internet and compare your performance on the bike to others who have the same bike.
The cyclist can choose between a total of five cycling modes – pure muscle power, the electric motor alone, or pedaling supported by the electric motor. In the pure mode, the drive power is purely the product of the cyclist’s legs, while in pedelec mode the rider is supported by the electric motor that then makes speeds of up to 80km/h possible and gives you a range of 50-70 kilometres. If you select eGrip, the Audi e-bike Wörthersee runs solely on the electric motor and can reach a top speed of 50km/h. The cyclist then controls forward momentum using a gripshift and can configure the power as desired using the computer.
