At 18 in, this is the last step before a full youth bike, sized for riders 47.2 to 59.1 in tall with a 23.5 to 26 in inseam. The saddle and handlebar both climb, stretching the fit across ages 4 to 8 rather than a single growth spurt. A kickstand folds down so the bike parks upright in a garage instead of leaning on paint. Thickened rubber tires and a soft-padded saddle keep longer rides comfortable, and the enclosed chain guard blocks the snag point at the sprocket.
