The invention relates to a bicycle drive (10) for an electrically drivable bicycle, the bicycle drive is provided with a pedal crankshaft (18) for inputting mechanical drive power, an electric machine (20) couplable to the pedal crankshaft (18) for inputting electric drive power and/or outputting generator power, and a Wolfrom transmission (30) disposed in the torque flow between the electric machine (20) and the pedal crankshaft (18). The radial inner installation space created by means of the Wolfrom transmission (30) results in a compact bicycle drive (10) for an electrically drivable bicycle having a high transmission ratio.
本发明涉及一种用于可电动驱动自行车的自行车驱动器(10),该自行车驱动器设置有用于输入机械驱动动力的踏板曲轴(18)、能够联接至踏板曲轴(18)以用于输入电驱动动力和/或输出发电机功率的电机(20)、以及置于电机(20)与踏板曲轴(18)之间的扭矩流中的Wolfrom变速器(30)。借助于Wolfrom变速器(30)产生的径向内部安装空间使得用于可电动驱动自行车的紧凑型自行车驱动器(10)具有高传动比。
