By opening the package, a "lock washer" was already on the axis of the front wheels, but not the right place. Unable to retrieve it to reposition it, we tried everything, eventually, break it! My son, handyman in his spare time, has found a way to replace it. Our grand-son of 2 years 1/2 is just as happy. What is significant is that the seat is adjustable. It is a toy that should last in time, if he resists our little breeze-all! !
