This wind-up toy was manufactured by Tech Specialties. It is pressed steel and features a clockwork mechanism that can be activated with a metal key. When wound, the car travels over and under the track, in a continuous motion. The riders also move back and forth as they race on the tracks, simulating that they are powering the car.
