The SX138 is a kids motorcycle with a sidecar-style basket on the side — a small luggage space the child can use to carry a stuffed animal or a friend's toy along for the ride.
It is made for older kids who already know how to balance a bit. There is no parental remote, so the child does all the driving. First runs are easier on a flat playground or smooth driveway, with a parent close by. The gearbox steps up automatically when the child presses the throttle harder, and the bike comes to a stop on its own the moment the throttle is released. A music panel plays a soundtrack, and headlights and taillights round out the look.
Best for paved areas around the home, not for gravel or rough ground.
