Kids grow quickly, making it challenging to find the right bike size that fits them perfectly for long. To inspire the next generation of riders, the Jett bike was designed to withstand the growth spurts and provide child-specific touch points that accommodate young riders' development. The Jett Multispeed features an adjustable handlebar and longer seat tubes that allow kids to fine-tune the reach and pedaling position. Additionally, the frame and components were reviewed to make the Jett one of the lightest bikes available. With the Jett, you can be sure that your child will always have a perfectly proportional and comfortable ride.
