Four braking and stability features help kids gain confidence on this 18 in bike. A height-adjustable handlebar from 30-32.5 in and a saddle that moves from 24-28 in let riders 47-59 in tall find a comfortable position. The front hand brake is sized for small hands, while the coaster brake lets kids stop by pedaling backward. Extra training wheels steady beginners, a fully enclosed chain guard keeps legs and clothing away from the drivetrain, and a removable basket holds toys and snacks.
