The front bumper and the upper window both come off, so the shape of this navy ride-on changes with the child inside and taller riders gain headroom. A 12V 4.5Ah battery moves it at 2 to 3 mph for ages three and up, with a parent remote that overrides the pedal and steering wheel at any moment. Lights hold steady or flash on command, and the built-in radio plays stored songs or streams from a phone over a wireless link. Steel and PP construction gives a 27.5 pound car rated to carry 66 pounds in the seat, and a portable handle with under-body wheels lets an adult tow it back when the battery runs flat. Assembled it measures 41.5 inches wide, 24.5 inches deep and 21.5 inches tall. Charging takes 8 to 12 hours.
