In Soviet Era there were automobiles for each class of people. We already told about Zaporozhets (for the middle class), Volga (for the upper class) and even Invalidka for disabled people, who were not able to drive ordinary cars.
The point is that the Soviet children also had their own pedal vehicles for kids, mostly produced at the real car factories. For example, AZLK factory, which produced Moskvich, had it's own section of pedal Mosckvich models.
See the photos below.
This one was constructed by pioneers (Soviet boy-scouts).
