The invention relates to a high-speed bicycle operated by a single person equivalent to that multiple persons pedal a long-force-arm rod, and aims to solve the problem that due to the fact that a rider needs to continuously and vigorously step on an existing manpower bicycle to want to run at a high speed, the human body feels tired and does not feel relaxed. The bicycle comprises an L-shaped swing rod, a rolling wheel, a long-force-arm pedal rod, a Z-shaped pulling rod, a connecting rod, an inner transmission and a conventional bicycle assembly, wherein the L-shaped swing rod is fixedly arranged on a middle shaft. The bicycle is simple in structure, reliable in action and suitable for implementation. Especially, the power is strong, the bicycle moves forwards at a high speed when people pedal up and down at low frequency easily, and the bicycle is an irreplaceable ideal light traffic tool for riding instead of walk.
本发明涉及一种单人骑相当于多人蹬长力臂杆操控高速自行车,为解决现有的人力自行车欲想高速行驶,则需要骑车人连续猛力踩踏,导致于人身感疲惫而不感轻松的问题,其包括中轴固装“L”形摆杆、滚轮、长力臂脚踏杆、副轴配装的“Z”字形拔杆、连杆、内变速器、常规自行车总成。其结构简单,动作可靠,宜实施。尤其是动力强劲,人轻松蹬低频率上下踩踏而自行车却高速前进,是不可替代理想轻型交通代步工具。
