Abstract

A two-wheeled bicycle that converts between a standard bicycle configuration for normal riding and an exercise configuration, where the bicycle is driven forward by alternating the effect of the saddle stroke. And the effect of the stroke of the pedaling stairs The saddle stroke consists of dropping the rider's body weight onto the saddle, which moves downward as a drive, rotates the crankshaft and brings two pedals, which are co-positioned upward. And the pedaling step consists of applying pressure on both pedals to bring the saddle back upward again, in an exercise style that the bicycle is protected from tripping. Provided in such a way that when the pedals are pedaling at the lower dead center, the upper weight The saddle is performed on the crank at an angle to the vertical. To keep the movement forward And with this arrangement, when the saddle is at the lower dead center, the pedals are located slightly ahead of the upper dead center to maintain the forward propulsion. In an exercise style, pedals may be forced to turn in one direction only with a serrated cogwheel mechanism. In which this prevents the pedals from hitting the rider's shin

Claims (6)

1.Two-wheel bicycles, whose rotation of the caster can be achieved by the effect of force in a manner alternating with the pedals and the saddle, are characterized in such a way that the saddle (5) and the pedals (4a, 4b). ) Is connected to or can be connected to the crankshaft (6) in such a way that when the crank of the pedals (6a, 6b) and the pedals (4a, 4b) are in the lower dead center position, the Relay between the saddle (5) and the crank of the saddle. (6c) The saddle crank angle (6c) is angled in such a way that the rider's weight is applied to the crank of the reading (6c) to propel the bicycle forward and when the saddle (5) is at the dead center position. Below, the crank of the pedals. (6a, 6b) and the stairs (4a, 4b) are located slightly ahead of the top dead center position. 2. Two-wheeled bicycles, as claimed in claim 1, in which the crank mechanism consists of a mechanism (12) for limiting the spin in the forward direction only. 3.Two-wheeled bicycles, as claimed in claim 2, the mechanism for such restriction is a serrated cogwheel mechanism (12). 4. Two-wheeled bicycle, as claimed in claim 2, the mechanism for such restriction is a clutch mechanism. 5. Two-wheeled bicycles as claimed in any of the 2 to 4 claims The mechanism for controlling the rotation can be released. 6.Two-wheel bicycles, according to one of the above claims, are convertible between the characteristics in which the saddle (5) and the pedals (4a, 4b) are connected to the crankshaft (6). In general, different positions, so that the bicycle can be driven forward by an alternating force effect on the pedals (4a, 4b) and with the saddle (5) and the normal riding style in the saddle. (5) will be connected. To the bicycle frame (1) and the 2 pedals (4a, 4b) are connected to the crankshaft (6) in different positions so that the bicycle can be driven in a normal way.
