The invention belongs to the technical field of bicycles, and particularly relates to a chainless adjustable labor-saving bicycle which comprises a supporting bicycle frame, a rolling assembly, a transmission mechanism and a loose joint assembly. The rolling assembly comprises a front rolling wheel and a rear rolling wheel, a pair of front fork frames are installed on the front rolling wheel, one ends of the pair of front fork frames are connected with a fixed connecting plate, and a rotating rod is connected to the fixed connecting plate; the transmission mechanism is arranged between the front roller and the rear roller and comprises a first angle gear and a second angle gear, and the first angle gear and the second angle gear are meshed with a first transmission gear; the loose joint assembly is arranged on one side of the rear rolling wheel and used for enabling the rear rolling wheel to swing, and therefore the rear rolling wheel is not prone to slipping. By arranging corresponding mechanisms of the bicycle, the bicycle does not need to be driven by a chain, so that the situation that the bicycle cannot move due to breakage of the chain is avoided, unnecessary troubles are reduced for a user, more labor is saved in the using process, the bicycle is more portable, and the user can ride the bicycle conveniently.
本发明属于自行车技术领域,具体涉及一种无链条可调省力自行车,包括:支撑车架、滚动组件、传动机构和活接组件;滚动组件包括前滚轮和后滚轮,前滚轮上安装有一对前叉架,一对前叉架的一端连接有固定连接板,固定连接板上连接有转杆;传动机构设于前滚轮与后滚轮之间,传动机构包括第一角齿轮和第二角齿轮,第一角齿轮和第二角齿轮上啮合有第一传动齿轮;活接组件设于后滚轮的一侧,活接组件用于使后滚轮能够摆动,从而使后滚轮不易出现打滑的情况。本发明通过对自行车相应机构的设置,使自行车无需再依靠链条进行传动,从而避免了因链条断裂而无法移动,为使用者减少不必要的麻烦,并且在使用过程中更加省力便携,方便使用者的骑乘。
