Introducing the Specialized Jett 24" Kids Bike: Where Growth Meets FUN! Kids, they're like shooting stars – always on the move and growing faster than you can blink. It's like there's this tiny window where the bike stars align perfectly with their growth spurts. But fear not, fellow adventurers, because the Jett is here to keep the excitement rolling and the wheels spinning.

Specialized cracked the code on kid growth – turns out those arms and legs are on a mission to outgrow the rest of the body. Armed with this knowledge, they cooked up a bike recipe that's a blend of pure magic and ergonomic genius. The Jett is more than adjustable; it's a growth companion that's as steady as a North Star. No more too small, too big, or "just for now" bikes. With the Jett, they're set for a lifetime of adventures.

Imagine an adjustable handlebar that grows with them, just like that beanstalk in the fairy tales. Those little arms are on a mission to stretch, and the Jett is their trusty sidekick. The 2-hole position cranks and longer seat tubes play a symphony of adjustability, ensuring those pedaling moments are just as comfortable as the stories they tell.

And let's talk about the weight – or lack thereof. Specialized has taken every piece of this two-wheeled masterpiece and made it as light as a feather. The Jett isn't just a bike; it's a rideable featherweight champion. You'll be bargaining, bribing, and even begging to get them off this bike.

So, there you have it – the Specialized Jett 24" Kids Bike. It's not just a bike; it's a futuristic, growth-spurt-defying, adventure-igniting wonder on wheels. Get ready to witness the next generation of riders conquer the world, one pedal at a time!


  • We designed the Jett Multispeed to be uniquely adjustable with 2-hole position cranks, adjustable handlebars, and longer seatposts so kids can dial-in the perfect riding position as they grow.
  • Every detail of the Jett Multispeed—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 Multispeed’s all-new A1 aluminum frame, alloy fork, Pathfinder tires, and 8-speed drivetrain make it one of the lightest kids’ bikes on the market.
