This 12-inch kids balance bike is designed to grow alongside active children roughly 4 to 8 years old, helping them build balance and confidence before transitioning to a pedal bike. Both the handlebar and seat adjust easily to match your child's height, and an enhanced locking system keeps every setting secure so the bike feels sturdy ride after ride. The wide, air-filled pneumatic tires cushion bumps and provide reliable grip across pavement, grass and packed dirt for a smooth, steady glide. A high-density sponge seat resists collapsing and wear, and its extended rear shape gives growing riders extra comfort and stability. The frame pairs a durable build with a stainless steel rim for long-lasting strength, supporting riders up to about 55 pounds. Each bike arrives partially assembled, so you simply attach the wheels and handlebar, adjust the seat height and it is ready to roll. Please review the size chart before ordering to confirm the fit for your child. It makes a rewarding gift that encourages outdoor activity and independent play.
