A pulley selector device for obtaining different speeds, characterized in that a cylindrical body is coupled to the motor shaft on which they can slide, by means of needle bearings and the convenient mechanical arrangement, idle pulleys, of different diameters, which can be put on alternatively in movement when engaging with them, respectively, a ball that is intentionally inserted into a cavity by the action of a movable element, displaceable inside a cylinder and provided with two cylindrical bodies that give rise, respectively, to the placement of the balls which in turn produce the rotation of the transmission pulleys, preventing the fixing of the position of the balls by means of conical and cylindrical elements fixed by a spring and pressing the tip of the spherical elements through its tip, activating the mobile system by a solid shaft provided with two annular notches that determine the point s operation and finished in a driving grip.
