Making kids’ bikes is about supporting and nurturing the spirit of riding from the first moment a kid’s feet hit the pedals. Kick-starting their passion for riding by delivering a great first ride means kids are more likely to ride for years to come.

ONE SIZE DOESN’T FIT ALL

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. Specialized knows that greater comfort opens the door for more riding. With kids’ bikes, comfort comes from a bike that fits well, and a design that’s kid-focused. Because of their growth spurts and growth patterns, the perfect fitting kids bike is a short-lived “just right.” Not only do kids deserve class-leading bikes, but they also deserve a bike that fits better, for longer.

“A better fit means more comfort, leading to more rides, kick-starting a lifetime of riding. We’re here to inspire that.” -Specialized Development Team

NEVER FEAR GROWTH SPURTS

Specialized asked, and parents said they want a bike that fits their kids for about 30 months or three summers. The Specialized teams did their research and found that kids ages 5-12 grow in their arms and legs faster than their torso. So, they needed to make a bike that was proportional and adjustable for quickly growing arms and legs to achieve the perfect fit multiple times in the bike’s lifetime. 

START THE KIDS OFF RIGHT

Specialized poured everything they've learned into the Jett.

First, they looked at how to make a bike proportional. Components may seem like minor details, but the kids’ study proved that they make a world of difference for our riders. A kids-specific saddle and narrow q-factor crank create hip-knee-ankle alignment. This helps to avoid knee pain and improve pedaling power - so riders can pedal further, faster. Narrower grips and short-reach brake levers allow for better control and maneuverability, inspiring more confidence in riders. These components were developed so kids can ride in capable comfort.

“The adjustability unlocks a whole new level of comfort and confidence, in both riding and buying.”
-Specialized Development Team

DESIGNED FOR GROWTH

Second, Specialized took the average growth curve of kids, and built 30 months of growth into the adjustability of the Jett, delivering more riding and more fun. Adjustability comes in the form of 2-hole positions for cranks, a long seatpost, and adjustable handlebars for extended reach. And what’s more, the Jett is a quality ride that weighs in at just 9.39kg/20.5lbs [24”], enabling riders to keep up with the grown-ups or lead the pack. Specialized has built the Jett to adjust to any level of capability, riding style, and growth pattern to help access kids’ full riding potential. 


By looking at the highest growth potential for girls and boys ages 7-12, Specialized was able to identify how much adjustability was needed to create a bike that would last for three seasons. This curve represents the maximum annual growth rate for a child, which occurs when children move from a low-height percentile to a high-height percentile. Now we have a much better understanding of how long the Jett will fit a rider.

A LIFETIME OF RIDING

The Jett is the vehicle for riders to learn, grow, and eventually graduate to the next steps in their riding journey. It starts with that first push on two wheels and quickly evolves into skid stops and dive-bombing trails. Kids are always going and always growing, so they deserve a ride that fits - a bike that will inspire a lifetime of riding. To us, that’s a goal well worth the effort.
