Two driving wheels and two freely rotating wheels let this 12V bumper car spin a full circle in place, which is the whole point of a bumper car rather than driving in straight lines. Twin 12V 25W motors move it at 1.9 to 3.7 mph. A soft NBR bumper wraps the body to cushion the knocks that come with bumping and racing. Children 3 to 8 sit against an ergonomic backrest behind a safety belt with feet on a non-slip rest. Slow start prevents a lurch, and a parent can override by remote.
