1. A CVT variator transmission box for a bicycle, wherein the CVT variator transmission box increases or decreases a speed of a rotational movement from pedals or from hands when a movement transmission method is provided, the CVT variator transmission box comprises
a transmission drive gear, wherein the transmission drive gear transmits the rotational movement from the pedals or from the hands to an input large gear through with a chain or a suitable movement transmission element, wherein the transmission drive gear is connected to the chain or the suitable movement transmission element from a central axis;
the input large gear, wherein the input large gear receives the rotational movement from the transmission drive gear and transmits the rotational movement to a front small gear in order to increase the speed;
the front small gear, wherein the front small gear transmits the rotational movement received from the input large gear, in speed as increased, to a front half-shaft pulley, wherein the front half-shaft pulley is associated with the front small gear from the center axis;
the front half-shaft pulley, wherein the front half-shaft pulley rotates a front half-ramp pulley positioned above on the front half-shaft pulley, by receiving the rotational movement from the front small gear,
the front half-ramp pulley with an oval shape or curved shape on a rear surface of the front half-ramp pulley, wherein the front half-ramp pulley turns with the front half-shaft pulley, wherein the front half-shaft pulley is without a shaft or the front half-shaft pulley is associated with the shaft and the front half-ramp pulley rotates a rear half pulley associated with the front half-ramp pulley via a belt;
sliding weights, wherein the sliding weights are positioned in ramp slots within the front half-ramp pulley and move towards a lateral surface of the front half-ramp pulley with an effect of a centrifugal force as the front half-ramp pulley rotates;
a variator ramp plate placed on the front half-ramp pulley and located on the rear surface of the front half-ramp pulley in a direction of a spring in an inwardly curved shaped,
the rear half pulley, wherein the rear half pulley is rotated by the front half-ramp pulley via the belt, and with a rear surface convex curved;
the belt, wherein the belt transmits a movement between the rear half pulley and the front half-ramp pulley;
the spring, wherein the spring takes the rear half pulley back to an original position of the rear half pulley by pushing the spring down when a system speed drops;
a rear half-shaft pulley located at a bottom of the rear half pulley and rotating together with the rear half pulley;
a rear small gear associated with the rear half-shaft pulley, wherein the rear half-shaft pulley is without the shaft or the rear half-shaft pulley is associated with the shaft on a center axis of the rear small gear and rotating with the rear half-shaft pulley; and
an output large gear, wherein the output large gear receives the rotational movement from the rear small gear, and transmits the rotational movement, directly or via any connecting element to a front wheel or a rear wheel.
