12” SPORT BIKE - Features mini rubber grips, a padded seat, a safety pad, the performance footrest, and an 11” starting seat height, so your toddler can easily straddle the bike at a young age. EASY TO ADJUST - As your child grows, you can adjust the seat & handlebar heights—no tools required. The Sport has a seat height range from 11-19” to fit a huge range of inseam lengths (12-20”). Plus, the foam tires will never go flat! WHAT IS A BALANCE BIKE? - A balance bike introduces your child to the feeling of being on a bike, building up their confidence by encouraging striding and allowing them to practice bike-handling skills. WHY DO I NEED IT? - Balance bikes are proven time and again to teach boys & girls to ride faster than training wheels. Your child will learn balance & steering, which makes transitioning to a bicycle with pedals much easier (when the time comes). JOIN THE STRIDER FAMILY - Meet the bike that set the world on fire and revolutionized the way kids learn to ride. Children as young as one are experiencing the thrill of riding without training wheels—before they're out of diapers.
