If your toddler can walk, a Strider balance bike will get your toddler cruising over dirt, grass, and pavement with ease. Designed to be steady, stable, and safe, the Strider is perfect for children from 18 months to 5 years old. The Strider 12 Sport model offers every feature a child (or parent) could want. It is the perfect balance of performance, options, and value, featuring more than 8 years of design evolution and manufacturing improvements. Unique 12.7mm steel handlebar is 43% smaller to allow better control with tiny hands. Custom logo mini-grips are soft urethane with protective ends. Machined-aluminum quick release allows No Tools height adjustment from 46-56cm (18-22 ). Strider-exclusive, ultralight one-piece wheels sport a raised-letter, five-spoke design with 10 bearing support gussets for maximum strength at the lightest weight possible. Top-quality sealed cartridge bearings roll smooth and never need adjustment. EVA polymer (industrial foam) tires are super light and durable yet offer a smooth ride. Best of all, they never need air and will never go flat. The durable, all-weather mini-saddle is designed specifically for beginning riders and their tiny hips. Smaller, narrower, and lighter than a typical saddle, the padded seat allows for proper riding position and posture. The Sport model also includes an additional extended seatpost for growing children, allowing seat-height adjustments up to 48 cm (19 in). Machined aluminum quick release allows No Tools saddle height adjustment from 28-48cm (11-19 ) for the perfect fit for your child. Unique, frame-integrated footrests are properly positioned directly below the saddle for natural bike balance. This position also fosters the advanced ability to stand while gliding as well as pumping and jumping the bike.
