One frame covers three stages: a parent pushes it as a stroller, a toddler walks behind it as a walking car at 26.8 in long, then rides it as a ride on car. Children 18 to 36 months sit behind a protective guardrail with an anti-tipping device under the frame, and a retractable footrest folds out once their legs reach. The canopy angles to block sun. A functional steering wheel actually turns, and a horn and engine sound play on 2 AA 1.5V batteries. Storage sits under the seat.
