The usual worry with a track toy is what happens once the track goes back in the box. This one answers it: the 16 pieces lock into a 7.2-ft circle for guided laps, and the same train drives freely across any flat floor without them. Overload protection cuts power if the motor is pushed too hard, and a backrest plus an anti-tilt bar keep a rider upright through the turns. Footrests slide out for feet to rest on and retract again. The seat lifts to reveal a storage box. Runs at 1.5 mph on a 6V pack, rated to 55 lbs
