This excellent basic folding bike design was created by an Englishman named Andrew Ritchie. The company he founded still builds bikes to this design.
Fun fact: Mr. Ritchie's original 1970s design used Bickerton-inspired folding handlebars. In the early 1980s his prototypes adopted the Dahon-patented 45º folding handlepost.
