In the mid teens, most motorcycles came with just one seat and the tandem seat was an optional accessory. Perhaps Floyd was using an tandem seat like this, from Fentress-Newton.
Or perhaps one from the Stoll Manufacturing Company of Denver, who made aftermarket motorcycle parts.
With Floyd being a motorcycle dealer and racer plus having contacts with Harley-Davidson, things were looking good for motorcycle racing on Pikes Peak.
In 1916 Floyd would come back to win the first Pikes Peak Hill Climb race on another Excelsior 61 motorcycle in the Professional Class.
