Specialized Jett 20" Single Speed Kids Bike Gloss Cobalt - Rider height: 102 - 139cm

Kids move fast, and grow faster. At times, it can seem like there’s a small window for the perfect bike fit. The right bike for a young rider is a delicate balance between too small, too big, and a short-lived just right. If we’re going to inspire the next generation of riders, we need to keep kids comfortably riding longer.

The Jett is designed so that you’ll never fear the growth spurts. Specialized did their homework to understand how kids grow and understand kids’ arms and legs grow more rapidly than their torso and then designed the Jett bike with child-specific touch points that withstand the development of young riders. The Jett is uniquely adjustable, perfectly proportional, and so light it's child-liftable.

The Jett Single Speed features an adjustable handlebar that allows kids to fine tune reach as their arms grow. The narrower saddle and grips were informed by a Retül study on kids to be the appropriate size and the frame and every component has been reviewed to make the Jett one of the lightest bikes on the market.

• Specialized designed the Jett Single Speed to be uniquely adjustable with longer seatposts and adjustable handlebars so kids can dial-in the perfect riding position as they grow.
• Every detail of the Jett Single Speed - including the 130mm Bridge saddle, narrower-diameter grips, and short-reach, tool-less adjustable brake levers was informed by Retül data from a kids’ research group to be perfectly proportional for young riders.
• A lightweight bike is simply more fun and the Jett Single Speed’s all-new A1 aluminum frame, alloy fork, Pathfinder tires, and single-speed drivetrain make it one of the lightest kids’ bikes on the market.
