There are no pedals, no battery and no chain - the car moves by turning the wheel side to side, which is the whole appeal and the reason it works on a driveway or a smooth indoor floor. Wheels flash as they spin. It measures 27 x 12 x 14 in with a 12 x 11 in seat, carrying 110 lbs at a weight of 7.72 lbs. PP and PU construction sits low to the ground so a two-year-old climbs on unaided. Nothing charges and nothing runs out mid-session.
