The Velio gets kids onto two wheels, safely, super early - under the age of 12 months - when our brain is developing faster than at any other – making upto 1million neural connections a second – by putting them on two wheels instead of a stable 3 or 4 wheeled ride on, suddenly they are actively engaged, their senses firing, driving the brain to make connections with their motor system.
The secret is achieving a safe level of instability - and the key to this is using spheres, to get technical – they are much less tippy, enhancing stability by more than a factor of 10 times.
Take the 1.4” tyre, you’d find on most balance bikes, the contact patch has only a small amount of lateral movement when it tips, and centre of mass – which is higher because the balance bike has a narrow base - is soon at the point where there is nothing between it and the ground to slow the fall and so the fall path is steep and short, and with a big distance between the centre of gravity and the centre of rotation momentum builds quickly and becomes very difficult to reverse – soon, the angular force is going to cause it to wash out completely.
Spheres however, have a far greater lateral forgiveness. As the Velio tilts, its spheres roll laterally – 5x further, a sphere always has mass between the centre of gravity and the ground, making the sure the fall path is so much longer and slower.
And as the spheres have a wide base, they have a lower centre of gravity – so as well as the point of rotation moving with the Velio 5 times further, the centre of gravity i
The spheres have the added benefit of lowering the centre of mass and so when you combine the lower centre of mass, the greater lateral movement of the contact patch, there is never really a great distance between the two – this means that momentum never really builds up and it takes an awful lot less force to return it to an upright position.
So as I said, in technical terms the Velio is an awful lot less tippy.
