Transition from training wheels to independent pedaling happens smoothly on this adjustable 16 in bicycle for children ages four through eight. Dual brakes provide layered stopping with a hand brake up front and coaster brake in back, plus a fully enclosed chain guard. The handlebar and seat both adjust for height changes, and three-layered rubber tires deliver shock absorption across varied surfaces. Reflectors boost visibility during late-afternoon rides. Arrives 95 percent pre-assembled.
