- microSHIFT 8-speed drivetrain with wide gear range for young riders

The Specialized Jett 24w is thoughtfully designed for young riders who are constantly growing and developing their riding skills. Its lightweight A1 Premium Butted Alloy frame keeps things easy to handle, while internal cable routing gives the bike a clean look and helps protect the cables from wear. The step-through unisex frame design makes it accessible for a wide range of kids and simple to hop on and off.
One of the Jett’s standout features is its adaptability. The adjustable crank arms allow for two pedal positions (130mm and 150mm), giving parents the flexibility to fine-tune the fit as their child grows. The handlebar setup and longer seatpost also help keep the riding position comfortable and efficient through growth spurts.
Specialized worked with data from young riders to fine-tune every contact point: the narrower diameter grips fit smaller hands, the short-reach brake levers are easy to adjust tool-free, and the Kids Bridge saddle provides plenty of comfort on longer rides.
The Jett 24w rolls on 24-inch wheels with Pathfinder Sport 2.0” tyres that offer a good balance of speed and grip across pavements, park paths, and light trails. The microSHIFT 8-speed drivetrain gives plenty of gear options for tackling varied terrain, while the simple V-brakes offer reliable stopping power with easy reach adjustment for little hands.
Designed to inspire confidence, the Jett 24w helps kids build skills and independence while giving parents the reassurance of a bike that grows with their child.
