When it comes to children's bicycles, the focus is on strengthening and promoting the fundamental idea of cycling. The joy of riding—a concept, a feeling, and an inspiration—begins as soon as children first sit in the saddle and start pedaling. Once the passion for cycling is ignited, nothing can stand in the way of a wonderful time outdoors filled with movement and unforgettable experiences. At Specialized, we understand that increased comfort opens the door to greater riding pleasure. Due to children's growth spurts, finding the perfectly fitting children's bicycle has typically only been a short-lived "just right." Our development team researched and discovered that children's arms and legs grow faster than their torsos between the ages of 5 and 12. Therefore, we needed to create a bicycle that is proportionally adjustable to maintain the perfect fit for an extended period—enter the Jett.
