The Air-Navigator provides a smooth ride with a push bar included. This is a family heirloom that children through the ages will enjoy and remember fondly when their own children are riding Kettrikes. It comes with a patented 3-in-1 Auto-Freewheel Coasting Pedal system, a patented Quik-Adjust Frame with low step-through design, and oversized tubeless air tires on German-made ball bearings. The rear-wheel navigation system includes a navigator mechanism with a simple on/off switch that can activate the navigator mechanism. No cables are needed.
