The short article is well worth a read, the thing was based on an 1894
Columbia high frame racing bicycle, and the transmission is _not_ the
chainless rotating shaft-drive that I first expected:

Here's the best picture of the locomotive-style transmission:

Note the pitiful spoon brake intended to stop a vehicle weighing about
150 pounds, coal-fired boiler and all:

Here's the early version, built around 1869:

It's in the Smithsonian and boasts 34-inch 12-spoke wheels:

And here's a modern replica of the 1894 version with a much better
picture of the locomotive transmission:

A movie of the bike in action, with choo-choo noises and visible
exhaust:

Nice seeing Mr. Roper again.

incrumental design!
ass the crap disappeared, with more motor carriages - automobiles,
fenders grew sides,
cars went lower. fenders were assimilated.
