Four coordinated systems make this 20-inch kids bicycle adaptable for growing riders, starting with a height-adjustable handlebar and 26-28.5-in saddle that help match children 8+ years old and 55.1-65 in tall. The sturdy metal frame works with wear-resistant pneumatic tires to support up to 143 lbs and maintain traction. A front hand brake shaped for smaller hands pairs with a rear coaster brake so kids can stop by squeezing or backpedaling. A fully enclosed chain guard, mudguards and reflectors help protect clothing and improve visibility. A kickstand, bell and removable front basket provide everyday parking, signaling and storage convenience on a 54.5 x 22 x 35 in bike.
