The invention relates to a bicycle hub, a bicycle driveline and a method of using the same. A bicycle hub includes a driver rotatable about an axis at a first rotational speed, wherein the driver includes a mating feature configured to engage a flywheel. The housing is rotatable about the axis at a second rotational speed. A non-adjustable gear train is coupled between the driver and the housing, wherein the gear train defines a single fixed gear ratio between the driver and the housing greater than 1: 1. A bicycle driveline includes: a drive unit having a user input member rotatable about a first axis at a first rotational speed; a link rotatable about a second axis at a second rotational speed; and a gear train coupled between the user input member and the chain ring. The gear train defines a gear ratio between the user input member and the chain ring of less than 1: 1. A method of propelling a bicycle is also provided.

    本发明涉及自行车轮毂、自行车传动系及其使用方法。自行车轮毂包括可围绕轴线以第一旋转速度旋转的驱动器,其中驱动器包括被配置为接合飞轮的配合特征。壳体可围绕轴线以第二旋转速度旋转。不可调节齿轮系联接在驱动器和壳体之间,其中齿轮系限定驱动器和壳体之间的大于1:1的单个固定传动比。自行车传动系包括:驱动单元,该驱动单元具有能够以第一旋转速度围绕第一轴线旋转的用户输入部件;能够以第二旋转速度围绕第二轴线旋转的链环;以及联接在用户输入部件和链环之间的齿轮系。齿轮系限定用户输入部件与链环之间的小于1:1的齿轮比。还提供了一种推进自行车的方法。
