1950 Whizzer Pacemaker Motorbike

Whizzer motor kits for bicycles, and complete Whizzer motorbikes like this one, were very popular after World War II. The relatively low cost of purchasing and riding a motorbike made personal mobility accessible and affordable for thousands of teenagers and adults. This motorbike was purchased by Americo Petrongelli in 1951 when he was 18. He rode it near his home in Chicago Heights, Illinois and commuted to work on it. He also gave rides to neighborhood kids on the fuel tank. After he married, he made the extra seat so that his three sons would not have to sit on the fuel tank.
