The 2023 Specialized Jett 20 Kids Bike is part of a new kids bike platform that’s designed to be the most adjustable and comfortable kids bike on the market. A new bike is a critical investment for families. Especially now, when parents are looking for safe, fun ways for their kids to get out and get active. The Jett is designed to deal with growth spurts and growth patterns so kids are more comfortable on their bike and want to ride more.

To design the Jett Specialized consulted the cycling industry’s best bike fitters, and used the same study tactics that they use with world-class athletes. During “Bring Your Kids to Work Day” at the Retül Office in Boulder, Colorado, the team put kids on bikes and observed the mechanics of how they were riding, optimizing that data in the design of the Jett.

The Jett is designed to have the adjustability to last for three summers. Specialized’s research found that kids grow faster in their arms and legs than their torso, so they have built a bike that can accommodate average growth for up to 3 summers. Adjustability comes from 2-hole positions for cranks, a longer seatpost, and adjustable handlebars for extended reach.

The Jett 20” comes with a sleek design, lightweight frame, and fast-rolling Pathfinder Tyres will have kids leading the pack or keeping up with the grown-ups. A kids-specific 130mm Bridge Saddle and narrow q-factor cranks create hip-knee-ankle alignment for the rider. This helps to avoid knee pain and improve pedalling power—so riders can pedal further, faster.

This bike is perfect for

Kids (and parents) who want a seriously light and fast bike that will last for 3 summers. The Jett is comfortable for longer rides and the Pathfinder tyres can handle a variety of surfaces.

Key Features
