Large outboard crank bearings from 1892:

Note how the hot new bottom bracket is daringly suspended below the
frame, rather than running through it.
The other photos show:
--an odd inch-pitch chain (sort of like endless giant half-links)
--front-fork foot-pegs for speedy coasting (it's a fixie)
--slotted cranks for exquisite pedal adjustment (modern cranks come in
coarse 2.5 mm steps)
--a powerful water-carbide lamp (acetylene's supreme)
--a spoon brake ready to tame the handsomely ribbed solid front tire
(probably a modern replacement, but red rubber was considered better
than black back then)
Cheers,
