This (aluminum) Belsize balance bike is significantly lighter than the (steel) Strider of the same size. I really feel this difference picking the bike up, and part of the balance bike experience is carrying it around to good riding spots! The Belsize bike is also slightly larger than the Strider and feels more solid/substantial, even though it’s lighter. It really feels like a scaled down adult bike (without pedals), rather than a kids toy. The rubber, air filled, tires are much more grippy and softer than the hard foam tires on the Strider.
