I'm on the contrary for the wheels. When any person learns a new skill, they basically learn several skills at once. And as we know, it's more effective to always learn one specific thing and then jump on another. So it seems more logical for me to teach a child to step on the auxiliary wheels and then turn. Once this child knows, the wheels can be removed and the child can concentrate only on holding the balance (instead of holding the balance, tapping and turning). Remember your first days in driving school ... how did it learn to get behind the wheel, pedal, advise, monitor traffic around you, pedestrians, signs, and still listen to the instructor? And how do you go when you have all the endings automated so that you don't have to think about them, and you can afford to think for a few tens of what will be for dinner? I vividly remember that when my dad took away my auxiliary wheels, I was unbelievably happy, because removing the wheels meant that I was moving somewhere.
