That photo is actually an outtake from Fritz Lang's "Metropolis". How about the taped on rear tire?

>There's something very SciFi about motor-paced racing, especially in the
>old days. This is frenchman Guy Solente, who set the motorpaced record in
>1955 at 74.642kph (46.4mph).
>
>Note the tread on the moto's rear tire, roller bar mounted on back, strange
>cut of his leather pants and jacket, the straps holding his number, the
>padded leather helmet with backward-facing cups, so he could hear his
>rider, and those strange shoes!
>
>Note also the LONG adjustable stem with strut connecting it to Solente's
>fork crown, tape securing the rear tubie to the rim in 10 places.
