An electric bicycle with an additionally-mounted center shaft is characterized in that a center shaft assembly of a common bicycle is replaced by an electric disc assembly, an outer ring part of an electric disc is a harmonic reducer, an inner ring part of the electric disc is an outer rotor hub motor, and the outer rotor hub motor is small in size, high in rotating speed and high in power density;the number of overall parts of the harmonic reducer is small; the electric bicycle is simple in structure, small in size, light in weight and high in transmission efficiency; when the electric disc assembly is additionally arranged on a common electric bicycle, only the original left bearing frame, the original right bearing frame, the original middle shaft, the original left pedal crank arm andthe original right pedal crank arm need to be replaced, and when the electric disc assembly is used for mountainous region variable-speed bicycle additional arrangement, the sprocket discs are replaced by multiple large and small sprocket discs. By fully utilizing the original speed change function, the electric disc assembly can quickly modify various idle bicycles into practical electric bicycles with low cost, a large number of existing bicycle resources are fully utilized to be upgraded and modified into practical novel products, and the requirements of broad masses and bicycle fans are met.

    一种中轴加装式电动自行车,它是将普通自行车的中轴组件更换成电动盘组件,电动盘的外环部分是谐波减速器、内环部分是外转子轮毂电机,外转子轮毂电机体积小、转速高、功率密度大,谐波减速器的整体零件数少,结构简单、体积小、重量轻、传动效率高,所述电动盘组件加装在普通电动自行车时,只需要将原有的左、右轴承架、中轴和左、右脚蹬拐臂更换即可,电动盘组件用于山地变速自行车加装时,将所述的链齿盘换成多个大、小链齿盘,充分利用原有的变速功能,电动盘组件能将闲置的各种自行车,低成本、快速改装成实用的电动自行车,充分利用了现有大量的各种自行车资源升级改造为实用的新型产品,满足广大群众和自行车爱好者的需求。
