Introducing the Specialized Jett 16" Single Speed Kids Bike—where FUN meets growth in the fast lane! Kids zoom through childhood and sprout up like sunflowers, making finding the perfect bike a cosmic challenge. It's like aiming for a bullseye on a comet. But fear not, Specialized cracked the code to keep your young speedster cruising comfortably.

Say hello to the Jett—a bike that's got growth spurts on lockdown. We put on our lab coats and dived deep into the mysteries of kid growth. Guess what? Arms and legs shoot up like rockets, leaving the torso in the stardust. Armed with this wisdom, we crafted a bike that grows with your kid, taking the phrase "bike fit" to a whole new stratosphere.

Our cosmic engineers cooked up a recipe for adjustability, balanced proportions, and kid-friendly lifting. You're not just setting the wheels in motion; You're setting the course for an interstellar biking adventure.

 Warning: Getting your little astronaut off the Jett might require negotiations, bribes, or even teleportation technology. So strap them in, rev up their childhood engines, and watch as they rocket through growth spurts, cosmic adventures, and endless smiles aboard the Specialized Jett 16" Single Speed Kids Bike.


  • We 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.
