Mechanism for increasing the speed of children's vehicles, characterized in that the propulsion element (rotating or reciprocating pedals around an axis, whose supports are fixed to the chassis or vehicle armor, or lever for the operation with the hands) transmits its movement, and turns it into a rotary, to an auxiliary crankshaft, on whose axle is mounted a sprocket, which in turn engages, directly or through the necessary sprockets to achieve the desired multiplication, with a pinion mounted in the axis of wheels, and comprised between two plates or discs, of greater external diameter, which avoid the possible shift of one gear with respect to the other.
