Wishbone Design Studio Original 2-in-1 Made from sustainably-harvested birch and eucalyptus wood and non-toxic glues and finishes, the Wishbone Design Studio Original 2-in-1 ($200) is an award-winning bike for a reason. It's easily adjustable, but unlike other balance bikes, the frame itself inverts to become a larger bike, giving your child more room to grow.
