Big fun comes on three wheels equipped with many patented features. All Kettrikes are perfectly designed according to the children's anatomic roadmap of motor skills. Invigorating solutions are typical for KETTLER. Our Quik-Adjust frame, patented Auto-Freewheel mechanism and Parental Control System all guarantee the highest level of safety. Kidproof engineering demonstrates that a low center of gravity combined with KETTLER exclusive patented features and exceptional manufacturing, give the Kettrikes utmost safety, quality and innovation. Each Kettrike is cleverly designed with a limited turning radius of 90 degrees wich offers freedom in play, but at the same time reduces the danger against tipping over.
