This a The prototype. and they say in yahoo new that 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 you are supported by the electric motor that then makes speeds of up to 80 km/h (50 mph) possible and gives you a range of 50-70 kilometers (31-44 miles).
