Frame Variations

Updated February 2011

There were many variations to the hasic H-frame design:

The original British design was built as a standard non-folding H-frame design from 1968. In 1971 a folding version was produced with the distinctive frame hinge. The design was definitely over-engineered and is not a quick-fold design for multi-mode commuters jumping on and off buses and trains. 

The New-Zealand built Raleigh Twenties had 3 major frame variations. The main difference from the Nottingham design was the lack of the bracing struts to the bottom bracket, and the main tube was a slightly smaller diameter: Most Raleigh Twentys from New Zealand were of the non-folding variety, but there were some folding versions made and here is the first photo that I have seen to confirm it:

There is also another variation which I would rather describe as a "separating frame" version.
