The budget-friendly Strider Classic comes equipped with our puncture-proof tires, ready to take all the punishment your little renegade can dish out. The lightweight steel frame has been specially designed for kid-level durability (this is the highest level of durability BTW). Oh yes, it also has the lowest seat height of any balance bike (28-40cm [11-16in]) on the market, so it fits an inseam of 30-43cm (12-17in) . Why? Because those little legs have to adapt perfectly to the bike they're riding on to gain confidence. The Strider Classic is a great no-frills choice for those who want to jump in the pool but aren't quite ready to play cannonball. If you're ready to cannonball and splash, we recommend the Strider 12 Sport (it'll grow even longer with your child).
