Topic By this new bicycle, the efficiency which is superior by the use power which is identical with the power which is used with the former bicycle is achieved.SolutionsThis invention rides and assembling the bicycle which has the pedal & the crank & the system, regards the device in order to improve the process of the kinetic energy which is filled by simplifying the motion of both pairs of the hands in round trip top and bottom movement, by the riding hand. As for device, the following part; The shaft (2) the axis (Ex) crank set of the right side and the left side which revolve around (1D and 1G) with, the rack the changer of implication and the rear (7) through, the chain set which the pinion (4), set of the annular gear (13, 13BIS), the chain (5), and propels the chain ring (6) by converting motion power and at the same time makes the rear wheel move before; It consists of. It is faced in the hub of the rear wheel where aforementioned rear wheel the rear fork (12) is installed the wheel (9) the gear cassette which is integrated inside the hub (8), or the rotary pin (Ax) by, furthermore the wheel & the fastener (25) the unidirectional free wheel which is kept (8) possesses the system outside, receives the driving force of motion of the hub. The frame is assembled the rear fork (11), upper tube profile (14), and the reinforcement fork (12) by, the system for the brake (10) keeps the reinforcement fork, in addition parallels to horizon Fx and is installed and at the same time the unidirectional free wheel transmission roller which is the annular gear (13, 13BIS) reinforces the tube which makes the installation system of the rotary pin move. Upper tube profile includes, device 3 on axial Cx, - 4, - to 5 the differential case which possesses the gear for the opposite rotary brake (15).
