Rolling motion alone lights the wheels on this 2-in-1 push car, so there is no battery to replace and no switch to forget. An adult pushes from the handle for an 18 to 36 month old, then the same frame becomes a foot-powered ride for a 37 to 60 month old. The handle locks at four heights between 29 and 36 in overall. Two swivel front wheels turn quietly indoors and grip outside, while rustproof aluminum tubing keeps the frame at 8.5 lbs A PU seat sits 11 in up with built-in footrests. Rated to 110 lbs and ASTM and CPSIA compliant.
