摘要
The invention concerns a device for assembling a bicycle equipped with a pedal crank system to improve the mechanics of the kinetic energy put in by the rider by simplifying the movement of the rider's feet into a reciprocating up and down movement It consists of the following parts: the right and left crankset (1D, 1G) pivoting about the axis (Ex) of the shafts (2), the chainset which includes the rack (3) and propels the ring gear (4) and the set of ring gears and the chain (5, 6) by transforming the play forces through a rear changer (7) and move forward the rear wheel vis its hub receiving the propelling force of the play of the hubs of the cassettes (8) integrated in the hub of the wheel (9), or external with a system of one-way freewheel (8), fixed on the rear fork (12) by the rotating pin (Ax) also maintaining the wheel fastener (25). The frame assembled through the rear fork (11), the upper tube profile (14), and the reinforcing fork (12) maintaining the braking system (10) and reinforces the tube which is placed along the horizontal axis Fx and moves the fixing system of the rotating pin of the ring gear, the freewheel one-wax transmission roller (13, 13BIS). The upper tube profile contains the device 3,4,-5, on Cx and the differential case with antirotation brake gears (15).
