This protective disc covers the front wheel and keeps feet out of the spokes, and it just looks darn cool. Printed to look like a genuine 1974 Marx Big Wheel front wheel, the wheel cover comes in two parts, a left side and a right side. Made of impact resistant PET plastic, the printing is on the backside for scratch resistance. New, larger port for pump makes it a breeze to air up. Light weight nylon fasteners included.
