2023 Specialized Jett Single Speed 16 Inch Kids Bike in Grey

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—spoiler alert, kids’ arms and legs grow more rapidly than their torso. They took to the books and designed a bike with child-specific touch points that withstand the development of young riders. The Jett is uniquely adjustable, perfectly proportional, and child-liftable—you’ll always be set to Jett.
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 appropriately size—with handbrakes on both the 16” and 20”. And what’s more, they designed the frame and reviewed every component to make the Jett one of the lightest bikes on the market. You’re going to have to beg them to get off this bike.
