The National Museum of Roller Skating website says, "Made by Antonio Pirrello in 1956, these skates feature a 19-pound gasoline motor that is worn like a backpack. The gas connects to the right skate to push while the skater holds her left foot out in front to steer. A second cable connects to the hand-held clutch to regulate speed. Quite a lot of speed. These skates can roll at up to 40 miles per hour! Mr. Pirrello and his motorized skates were featured in the magazines Life and Popular Mechanics and were guests on You Asked for It and The Today Show."
