The Strider 12" Sport Balance Bike is designed to help kids as young as 18 months learn to ride a two-wheeled bike. The Sport is Strider's best all-around model. Mini-grips mean little mitts can easily take control and make this lean, mean, durable bike the biggest bang for your buck, which is probably why it's their best seller. The 12 Sport is the perfect bike to take your child from baby steps to big strides, all without busting out a toolkit (tool-free seat and handlebar adjustment AND tires that never go flat). The Strider Sport has a seat height range from 28-48 cm (11-19 in.), which means it fits a huge range of inseam lengths (30-51 cm [12-20 in.]). The cushy, padded seat and an additional extra-long seatpost means your child will get years out of their Strider.All the details aside, now your tiny toddler has the power to keep up with you when you're out and about. No more strollers or hauling them on your shoulders. Your child can experience the truly amazing freedom that comes with being a part of the Strider family.
