Children's bicycles are all about strengthening and nurturing the fundamental idea of cycling. Riding joy — a term, a feeling, and an inspiration — is formed the moment children first sit in the saddle and start pedaling. Once the passion for cycling has been kindled, nothing stands in the way of a great time outdoors with lots of activity and unforgettable experiences. At Specialized, we understand that more comfort opens the door to more riding fun. However, due to children's growth spurts, the perfectly fitting children's bike was previously only equipped with a short-lived "just right." Our development team researched and found that the arms and legs of children aged 5-12 grow faster than the torso. We needed to develop a bike that is proportionally adjustable to maintain the perfect fit for a longer period — enter the Jett.
