This stylish base unit is the basis for all combinations in the CombiCar family. Intended for girls and boys, the clever design allows children to easily change between the different set-ups. Sold separately, the five add-ons to this base unit are the basic handle- bars, an excavator, a crane, a doll’s seat, and a trailer. With all five attachments and one base unit, a child can create nine different combinations of vehicles. The base unit is made of beech and fitted with steel rods for the steering column and each axel. The tires have polyethylene treads, making for smooth travel. The connecting pin for front-end accessories is fitted with an elastic peg release that requires no tools and no parents when changing set-ups.
