The Sport is our 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 our 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. For Ages 18 months to 5 Years. Fits inseam lengths (30-51 cm [12-20 in.]). Max. Rider Weight: 27 kg (60 lbs.) The Strider Bike Stand does exactly what the name says: keeps your bike standing up tall and looking proud after you’ve had a hard day of riding. Fits Strider 12 Classic, Sport, Pro, and Strider 14x Sport.
