Dot Dot Dot Dot Dot Dot Dot Dot

In the above gif, the white dots are each moving in a straight line along the spokes of a wheel of radius 1 meter. This gives the appearance of a white circle that moves around.

If the white dots complete 1 revolution in 1 second (back to the same starting position and velocity), what is the speed at which the center of the white circles moves?
