Four size options share the same structure, and the 14-inch girls bike uses an adjustable 19.5-23 in saddle height to match riders with 18.5-22 in inseam and 37.4-43.3 in height. Kids control speed with a handbrake on the handlebar and a coaster brake at the rear wheel, while two removable training wheels help them practice balance as their skills grow. A soft padded seat and anti-slip grips support steadier handling on rides. The front bike bag carries small toys, and the bell, streamers, mudguards, reflectors, and wear-resistant multi-layer rubber tires support everyday use and visibility.
