    • A recumbent bicycle is powered by the driving of a crank spindle that rotates on an axis generally coincident with that of the front wheel. The crank spindle is disposed within a spindle housing supported from the front of the bicycle frame, and the spindle housing supports the front wheel through a steerably turnable intermediate hub. Steering of the handlebars causes the front wheel to turn to steer the bicycle, while the crank spindle remains in a fixed orientation to the frame so that the bicycle can be continuously driven with pedals connected to the crank spindle, which in turn is connected to the rear wheel through a sprocket and drive chain assembly.
    • 卧式自行车通过驱动曲柄轴来驱动,所述曲柄轴在大致与前轮的轴线重合的轴线上旋转。 曲柄轴设置在从自行车车架的前部支撑的主轴壳体内,并且主轴壳体通过可转向转动的中间轮毂支撑前轮。 手柄的转向导致前轮转动以转向自行车,同时曲柄轴保持与框架的固定取向,使得自行车可以连续地驱动,脚踏板连接到曲柄主轴,脚轮又连接到 后轮通过链轮和驱动链组件。
