Large threaded rubber tires give this 18 inch children's bicycle sure footing across different road surfaces, and the sturdy carbon steel frame with fully enclosed chain guard keeps riding safe. Two braking methods are available, a hand brake and a rear coaster brake, so a child can use whichever feels natural. Handlebar and seat heights adjust for riders roughly 47 to 59 inches tall, training wheels add stability early on, and a soft seat cushion improves comfort. A bell, storage basket, multiple reflectors and a kid-friendly kickstand are fitted, and the bike arrives 95 percent assembled.
