Offering a smooth transition from stroller to trike, the brightly colored Kettler Kettrike Air-Navigator Tricycle includes a parental control steering system that locks handlebars into place for parental guidance when using the optional 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 Air-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.
