A bicycle with a novel gearbox transmission bicycle transmission comprises a frame, the frame is of an L-shaped structure, a long arm part of the L-shaped structure forms a cross beam, a short arm part of the L-shaped structure forms a longitudinal beam, a handlebar and a bicycle head are rotatably arranged at the front end of the cross beam, the bicycle head is connected with a front wheel through a roller set, and the front wheel is connected with a rear wheel through a roller set. A saddle is arranged at the joint of the cross beam and the longitudinal beam, the tail end of the longitudinal beam is integrally connected with a fixing ring, a pedal ring with pedals is arranged in the fixing ring, the rear side of the fixing ring is connected with a gearbox body internally provided with a speed change mechanism, and the speed change mechanism is in driving connection with the pedal ring. And a rear wheel which is connected with the speed change mechanism and is driven by the speed change mechanism to rotate is arranged in the speed change box body in a penetrating manner. Interference from the external environment is small, a transmission structure of a product is concentrated in the gearbox, maintenance is convenient, and the embarrassing situation that a whole vehicle is disassembled at a damaged position is avoided. Gear transmission is adopted, and the transmission efficiency is greatly improved.

    一种具有新型波箱传动单车变速器的自行车,包括车架,所述车架为L型结构,所述L型结构的长臂部分构成横梁,短臂部分构成纵梁,所述横梁的前端能够旋转的设置有车把和车头,所述车头通过滚轮组连接前车轮,所述横梁与纵梁的交接处设置有车座,所述纵梁的尾端一体连接有固定环,所述固定环内设置有带有脚蹬的脚踏环,所述固定环的后侧连接有内部设置有变速机构的变速箱体,所述变速机构与所述的脚踏环为驱动连接,所述变速箱体内贯穿的设置有与所述变速机构相连接、并在变速机构的驱动下进行旋转的后车轮。本发明受外部环境干扰小,产品的传动结构集中在变速箱中,检修方便,避免了坏一处拆整车的尴尬处境。本发明采用齿轮传动,传动效率大大提高。
