The Buzzy can now also be used as a push-car, so your child can get out and about safely. You can use the push bar to maintain control of the go-kart and child. The Buzzy's stability keeps it upright at all times, even if the child fidgets, goes over bumps or uneven surfaces. It stands apart from many 2in1 tricycles which are less stable on account of the 3 wheels. Does your child get tired and want to be pushed, or does he just want to play? In the blink of an eye, you can convert the Buzzy from push-car to go-kart or vice versa.
