Raleigh produced the "Twenty" model to compete with the original small-wheeled Moulton bicycle. Production began in 1968 and reached the height of popularity in 1977 before the Twenty was finally discontinued in 1984.
Twenties were produced in both standard and folding forms, with the folding form allowing for more convenient transport and storage. Although a vintage Raleigh Twenty folding bicycle is quite heavy by modern standards, there has been renewed interest in this model today both for its vintage charm and portability. Levers on the bicycle allow the frame to collapse in half and the seat post and handlebar stem to be pulled in for easy transport, enabling a vintage Raleigh Twenty folding bicycle to travel on train or in the trunk of a car.
