Front hand brake and rear coaster brake give young riders two ways to slow down, helping them control stops as they squeeze the lever or backpedal. The 14-inch wheels and 39.5 x 19.5 x 30 in frame fit kids about 37.4-43.3 in tall, while the 19.5-22 in adjustable saddle and locking device let adults set seat height as children grow. Two removable training wheels create a stable triangular setup for learning, and a front basket, fenders, non-slip pedals and reflectors support everyday rides within the 110-lb seat capacity.
