This invention relates to a children pedal-driven scooter. It comprises two driving systems instead of previous pedal driven shaft. Between the two driving systems there is a fixed main gear (7). Each system has a saw-edged gear (5) connected with the main gear (7) by a shaft (6). Each saw-edged gear (5) meshes with a saw-edged rack (3), fastened with a pedal (1 ). Moreover each pedal (1 ) is equipped with a spring on the body surface to lift the pedal (1 ) to the upper position. Pressing the pedal (1 ) downwards, the saw-edged rack (3) rotates the saw-edged gear (5) driving the shaft (6) and in addition the main gear (7). A chain (9) connects the main gear (7) with a posterior gear (10) fixed to a wheel, driving the scooter. Added to this, the driving system can be used in many purposes other then in a scooter.
