Didicar
Didicar is a self-propelled ride on toy made of polypropylene designed for children aged 3 years and up. The Didicar starts moving when the rider turns the steering wheel left and right. Thanks to the rotation of the steering wheel, the Didicar leverages its frictional force, gravity and inertia to move forward and backward. It is designed for flat surfaces, both indoors and outdoors.
