Did someone take this seriously?
I don't believe that the chain is doubled, as that would requitre dual chainwheels and cogs, or at least a groove cut into them to accommodate a middle chain plate. However, they were very wide. Here's detail photo showing the width and Overman's hubs, with straight pull spokes that produced a cross pattern. Overman were quite inventive, They also develped hollow, aero rims and hollow, large diameter, bottom bracket spindles.
