    摘要： A dual driven cycle and a kit for converting conventional, single driven cycles into dual driven cycles are disclosed. The invention is suitable for accommodating bicycles, motorcycles, dirt bikes, and other conventional cycles. These cycles have the known elements of a pedal-gear-chain driven first wheel and a non-driven second wheel. The kit comprises four general elements. First, a sprocket is connectable in fixed relation to the non-driven second wheel for conjoint movement with that wheel. Second, to receive power from the conventional drive train, a drive gear is mounted on either the pedal gear or chain of the cycle. Third, a cable gear is provided for mounting with respect to the cycle's frame and meshing with the sprocket. This cable gear drives the sprocket and, of necessity, the cycle's previously non-driven second wheel. The final general element of the kit is a rotatable cable which connects the cable gear to the drive gear and transfers the rotational motion of the drive gear to the second wheel.

    摘要翻译： 公开了一种双驱动循环和用于将常规单个驱动循环转换为双驱动循环的套件。 本发明适用于容纳自行车，摩托车，污垢自行车和其他常规循环。 这些循环具有踏板齿轮链驱动的第一轮和非驱动的第二轮的已知元件。 该套件包含四个一般要素。 首先，链轮可以与非驱动的第二轮的固定关系连接，以便与该车轮联动。 第二，为了从传统的传动系统接收动力，驱动齿轮安装在踏板齿轮或循环链上。 第三，提供了一种用于相对于循环框架安装并与链轮啮合的缆索齿轮。 这种电缆齿轮驱动链轮，并且必要时驱动该循环之前的非驱动的二轮。 套件的最终一般元件是可旋转的电缆，其将电缆齿轮连接到驱动齿轮并将驱动齿轮的旋转运动传递到第二轮。
