Balance bikes teach balance before pedaling. Learning to pedal is easy if you know how to balance. Learning balance is fairly easy, too. But learning them concurrently is hard. With a balance bike instead of a trike or a standard bike with training wheels, it’s much easier for a child to learn the balance, steering dynamics and handling required to ride a bike. My son, at 2 1/2, can go at least a mile on his Skuut bike, and is learning all the skills he’ll need, so that when I get him a normal bicycle, with pedals, he won’t need training wheels.
The design of a balance bike is brilliant—it’s actually similar to the design of the first bicycles (velocipedes) that had no drivetrains. The particular brand of a running or balance bike for kids is not of much concern. Cool Tools previously featured the Likeabike, which was imported from Europe and lovingly crafted, but notably expensive. You can find cheap $50 metal balance bikes these days, but we use the current wooden standard Skuut which is good enough quality for $85.
