The Raleigh "Twenty" is a small-wheeled bicycle which was introduced to the market in 1968 as a competitor to the original Moulton bicycle. Raleigh already had a more direct competitor in the RSW-16 (Raleigh Small Wheel 16") bicycle. Initially it was not aggressively marketed, but it was a much better bicycle than the RSW-16. The "Twenty's" larger 20" wheels made it smoother and had less rolling resistance. In 1970 the RSW-16 was selling rather poorly, so Raleigh decided to market the "Twenty" more heavily. In 1971 a folding version was released under an old Moulton name the "Stowaway" (anecdotal evidence suggests that they were available in Canada since 1969). In 1974 the RSW-16 was discontinued and the "Twenty" became Raleigh's main small-wheeled bicycle in production. In 1975, 140,000 were manufactured in the UK alone, which nearly equalled the entire sales of the Moulton from 1963-1974. It was Raleigh's biggest seller in 1977, though sales tapered off after this, its final year of production was not until 1984, giving the Raleigh Twenty a 16-year production lifespan.
