Offering a smooth transition from stroller to trike, the brightly colored Kettler Supreme Navigator Stroller Trike Tricycle includes a parental control steering system that locks handlebars into place for parental guidance when using the canopy pushbar. The Auto-Freewheel allows your child to rest his or her feet on the pedals while you guide them with the pushbar. When your child is ready for biking, a simple on/off switch (located under the Kettler logo on the handlebar stem) unlocks the front steering stem and the Supreme Navigator operates as a standard freewheel tricycle with coaster brake stopping. The durable metal frame has an easy step-through design, and it can quickly be adjusted to accommodate your growing child or fit another rider. The three Komfy Ride tires are filled with air (via regular Schrader valves), which give the trike true road gripping traction and responsive maneuvering. The blue bucket seat provides excellent riding comfort, and the sturdy yellow tipping bucket on the back of the trike is great for transporting everything from toys to sand. The frame is made of high carbon steel and has a fade-resistant polyester powder coat finish in brilliant red. This tricycle meets ASTM safety requirements. KT8839-590.
