Four wheel sizes share a common design, and this 16-in kids bike is sized for riders ages 4-7 years with a 41.3-51.2 in height range. The 46 x 22 x 31 in frame combines metal with PP, TRP and PVC parts to support up to 110 lbs while standing up to everyday use. A front hand brake and rear coaster brake let kids control speed by lever or backpedaling as they gain confidence. Removable training wheels add stability while they learn, and an enclosed chain guard, pneumatic tires and front basket support daily rides and play.
