Riders moving up from a balance bike land here, where both the handlebar and the saddle adjust so a 14-inch frame keeps fitting through the 3 to 5 year window. Saddle travel runs 19.5 to 22 inches for that size, and the handlebar moves within a 3-inch band, so posture stays upright rather than hunched. Check the child's inseam against the saddle height before the first ride, because reaching the ground at a stop is what builds confidence. Anti-crack, wear-resistant tires hold their line on asphalt, cement, brick and short grass. A front hand brake gives small hands something they can actually squeeze, while the rear coaster brake stops the bike by pedalling backward. Two detachable training wheels keep the frame upright at the start. The enclosed chain guard blocks pinching and the seat carries up to 145 pounds.
