The invention discloses a body-building and labor-saving bicycle riding at a high speed and driven by an oscillating bar, belonging to the technical field of bicycle manufacturing in the mechanical manufacture industry. The body-building and labor-saving bicycle riding at a high speed and driven by the oscillating bar is characterized in that an increasing speed gear mechanism over level-two is used for transmission; a
crank mechanism and a link mechanism are driven to move by a pedal oscillating bar or a manual oscillating bar; thus the bicycle is driven to ride at the high speed; the rear wheel can be a single wheel and also can be two wheels; the height of the back rest of a seat can be liftable; a generator, an electric storage
bottle, a
speedometer, a steering indicating lamp, a width lamp, a
brake lamp, rearview mirrors, an electric horn with a high sound volume and a tool box are driven by a rear wheel shaft; the rear wheel shaft is provided with a
brake, and the edge of the front wheel is provided with a
brake; the whole bicycle is provided with a casing; and two sides of the casing are provided with bicycle
doors. The designed speed and riding speed of the bicycle can reach more than 170 killometers per hour, thus the bicycle is a fully green efficient tool for riding instead of walk with zero
energy consumption and
zero carbon discharge and the bicycle has equivalent body-building effects with special body-building machines such as a running
machine, a pedal
machine and the like. The application of the bicycle is as follows: the bicycle can replace an ordinary bicycle, an electrical bicycle, a light and convenient electro-tricycle, a motor cycle and a domestic car with low performance.
