Supergeared French Bike Gives Cyclist Choice of Several Speeds (Jul, 1954)

This bike seems like it’s a little more complicated than it needs to be.

Supergeared French Bike Gives Cyclist Choice of Several Speeds
There’s a weird assortment of sprockets and chains incorporated into a supergeared bicycle invented in France. The chains appear to run at random all over the framework of the bicycle, but the arrangement gives the rider a choice of several gears. The bicycle has two-wheel brakes.

    It seems to have a flywheel and clutch arrangement, which looks like a fun way to launch a bicycle from standstill.

    I think Sweavo is right, it looks like he tried to invent something that didn’t use the already commonplace derailleur system:

    From Wikipedia:

    Various derailleur systems were designed and built in the late 1800s. The French bicycle tourist, writer and cycling promoter Paul de Vivie, aka Velocio, (1853-1930) invented a two speed derailleur in 1905 which he used on extensive forays into the Alps. [1] Some early designs used a system of rods to move the chain onto various gears. Derailleurs did not become common road racing equipment until 1938 when Simplex introduced their cable shifted derailleur. In the early 1950s the cable-operated, parallelogram variety used on today’s bicycles was introduced by Tullio Campagnolo, who also invented the quick release skewer for attaching the wheels. [2] With Campagnolo’s introduction of the parallelogram derailleur, Campagnolo became the standard for high quality derailleurs for several decades with its Gran Sport, Record, Super Record gears.

    I don’t know.
    Is it possible to have more rotating toothed gears near my genitals and ass?
