The Spherovelo is the worldäó»s first ride on to accelerate the development of young children by helping them make the connection between their senses (vision, pressure, equilibrium...) and their motor system. Some might call it balance but itäó»s really more about the coordination of our muscles in response to what we see and feel.
It manages this by being a ride on thatäó»s unstable on the one hand (so that the child is required to effect some control - like with a bike) but safe on the other; a combination never before achieved.
The reason this is so important is that this is the age when weäó»re first developing our coordination and the age when weäó»re most receptive to experiential learning. The Spheroveloäó»s design, essentially two great spheres, is based upon the fundamental principle that a ball able to move freely will just relocate and not tip like a wheel.
By replacing wheels with a special arrangement of spheres weäó»ve been able to simulate a bike, but with increased lateral forgiveness so that it becomes very difficult for a child to fall onto or off of. In other words, because of the spheres, the Spherovelo is the worldäó»s first safely unstable ride on, a balance bike for very young children.
