Worth knowing before it arrives: bubble solution is not supplied in the box, so pick some up alongside it. Controls stay simple enough for a first rider, with one foot pedal to go and a three-position switch for forward, stop, and reverse. Three wheels in a wide triangle resist tipping through a turn and are rated to hold up to 66 lbs An LED headlight, music, and a flame-pattern shell finish it. ASTM and CPSIA tested.
