This 12 inch kids bike is a practical first bike for young beginners ages 3 to 8, including a 4 year old or 5 year old rider. The adjustable handlebar and seat adapt to your child's height, so the fit stays comfortable as they grow. As a toddler bike with training wheels, it keeps first-time riders steady on sidewalks, driveways and park paths, and the detachable wheels come off when your child is ready to balance alone. A dual brake system pairs a front hand brake with a rear coaster brake, giving boys and girls two easy ways to stop, and durable, shock-absorbing tires keep the ride smooth. An enclosed chain guard helps protect little feet and reflectors add visibility. A sturdy metal frame, anti-slip pedals, an ergonomic seat and an included bell complete this children's bicycle, which meets Astm and Cpsia safety standards. Adult assembly and adult supervision are required. Not suitable for children under 3 years.
