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