Fourteen-inch wheels and detachable training wheels let kids practice balance on this bike, then switch to two-wheel riding when they are ready. The adjustable seat changes the 20-21.5-in saddle height to match riders about 37.4-43.3 in tall, helping the bike fit through several growth stages. A front hand brake pairs with a rear coaster brake so children can manage speed and stop in a familiar way. Textured pneumatic tires add grip on sidewalks or grass, while a chain guard, bell, reflectors, bright monster graphics, and a customizable number plate support outdoor riding and visibility.
