Kid-Correct Features
-
Kid-Correct Weight
Is no more than 30 to 40-percent of a child’s weight, because a light bike is easier and more fun to ride.
-
Kid-Correct Standover
Makes it easier for kids to get on and off the bike.
-
Kid-Correct Reach
Keeps kids in comfortable control of the bike.
-
Kid-Correct Gearing
Lower gearing and shorter crankarms are right for shorter, less powerful legs, with a narrower Q-Factor (width) for a more natural stance. All this makes it easier for kids to get moving and to stay moving.
-
Kid-Correct Parts
Sized to fit kids’ anatomies, with smaller handlebars and grips, kid-specific seats and pedals sized for kids’ feet. Hand brakes are paired with coaster brakes on single speed bikes so kids can build the skills they will need for their next bike.
-
Kid-Correct Colors
Bright, fresh and eye-catching, because for kids, a fun bike is one that looks great.

-
Single-Speed

-
Just Right
Comfortable grips and saddle. Brake levers that are adjustable to fit every hand. Narrow-stance cranks for efficient pedaling. The details make all the difference.
