The Kids Bike has both a balance mode and a bike mode. Kids bikes can also be ridden faster and more stable for children 41-46 inches and can be ridden as they get older. Made of quality steel to stand up to the bumps and bruises of the learning process, the durable steel frame is backed by our Limited Lifetime Warranty. The kids bike comes with black tires and a single speed and requires minimal maintenance due to its simple design. The 16-inch kids bike has an adjustable seat with a range of 21-27 inches. At this age, children grow in height and it can be adjusted to fit their height. Adjust to match the height of the child's ride to provide better support. The inch bike is equipped with reflective sheets to make it easy for parents to keep an eye on their children while playing outdoors and increase the safety of riding at night. The handlebars with non-slip silicone grips are sturdy and durable, and the flexible swivel mechanism and bell on the bike increase the sense of security for kids.
