The four wheels make the BERG Buzzy Go-Kart much more stable than a three-wheeler. It’s really safe! And because the pedals aren’t connected to the handlebars, your child’s feet remain firmly on the pedals, even in the sharpest turns. This makes pedaling a lot easier, and the Buzzy glides over the sidewalk or asphalt. And it goes backwards just as fast! Do you like music? The Buzzy Beatz and Buzzy Police come standard with a built-in Soundbox in the steering wheel.
