Sized for ages 4 to 7, this 16-in kids bike arrives 95 percent assembled, so a parent only fits the handlebar, pedals, and training wheels. Saddle and handlebar both raise as a child grows, covering riders roughly 41-in to 51-in tall with a 21-in inseam. Threaded rubber tires roll across sidewalk cracks and packed dirt, and a handbrake plus coaster brake give two ways to stop. A carbon steel frame, enclosed chain guard, front basket, bell, and reflectors complete a bicycle that meets ASTM and CPSIA requirements.
