One frame covers three stages: a foot-powered sliding car, a push walker steadied by the folding handle, and a parent-towed ride on with a front rope for tired legs. Steering stays linked in tow mode, so the car tracks behind instead of swinging wide on a corner. A widened wheelbase and low seat keep the center of gravity down, while rear wheel damping bleeds off speed before a fast push can tip the nose. The basket under the seat swallows blocks, snacks, and picture books for the walk home from the park.
