Specialized Jett 20 Kids' Bike
Kids grow quickly, making it challenging to find the right bike fit that keeps them comfortably riding for longer. The Jett Multispeed is the solution, designed to accommodate those growth spurts without a hitch. Understanding that kids' arms and legs grow faster than their torsos, we created child-specific touch points to withstand their development. The Jett is uniquely adjustable with 2-hole position cranks, adjustable handlebars, and longer seatposts, ensuring the perfect riding position as they grow. It's not just about adjustability; every detail, from the 130mm Bridge saddle to the narrow-diameter grips and tool-less adjustable brake levers, is perfectly proportional for young riders, backed by Retül data. Plus, the Jett is one of the lightest kids' bikes on the market, thanks to its A1 aluminum frame, alloy fork, Pathfinder tires, and 7-speed drivetrain. You'll have to pry them off this bike.
