Dear Rob,

Sociable and tandem tricycles and quadricycles were popular back in
the 1870s and 1880s.

A nice page about the Rudge tandem rotary tricycle:

A few examples:

The gallery above, with more tricycle stuff:

The obvious drawback of the side-by-side sociable is that is much
wider than the in-line tandem, leading to much more wind drag and
reduced agility.

Uncle James Starley's tandem Salvo in the upper right:

Most of the commercially successful rear-wheel chain-drive safety
bicycles that appeared in 1884 and 1885, such as nephew John Starley's
Rover, used parts from tricycles and quadricycles, which had developed
chains and sprockets, remote front steering, and elaborately
adjustable seating.

Cheers,

Carl Fogel
