Just reading the Hetchins website, pretty interesting stuff.
The Trio (below) was a multi-functional frame. It had a patented rear dropout with two slots allowing the rider to lengthen or shorten the wheelbase, and two forks for road and track. The idea was not popular; probably only a dozen or so were made and only one is known to have survived.
