The End of Training Wheels?

I know I've got a little while, but this new bike holds the promise to making learning to ride a breeze, as well as open up bike riding to individuals whose physical handicaps would have made a normal bicycle difficult to ride. The back wheels stand apart at slow speeds to work like a tricycle, offering stability. But as you ride faster and faster, the two narrow wheels come together to give you the normal bicycle experience. As you slow, the wheels come apart again.
