, the archetypal bicycle. Johnson's "pedestrian curricle" was patented in London in December 1818, becoming Britain's first bicycle. It featured an elegantly curved wooden frame, allowing the use of larger wooden wheels. Several parts were made of metal, which allowed the vehicle to be lighter than the continental version. Although Johnson referred to his machine as a ‘pedestrian curricle’, it was formally referred to as a ‘velocipede’, and popularly as a ‘Hobby-horse’, ‘Dandy-horse’, ‘Pedestrian's accelerator’, ‘Swift walker’ and by a variety of other names. Johnson made at least 320

in the early part of 1819. He also opened riding schools in the Strand and Soho. In May 1819 he introduced a dropped-frame version for ladies to accommodate their long skirts. For about six months the machine had a high profile in London and elsewhere, its principal riders being the Regency dandies. About eighty prints were produced in London, depicting the 'hobby-horse' and its users, not always in a flattering light. Johnson undertook a tour of England in the spring of 1819 to exhibit and publicise the item. Nevertheless, by the summer of the same year the craze was dying out, and a health warning against the continued use of the velocipede was issued by the London Surgeons. In Johnson's machine, like that of von Drais, propulsion was simply by ‘swift walking’, with the rider striking his (or her) feet on the ground alternately. However, it led directly (albeit after a long delay) to the invention of the bicycle in the 1860s, when rotary cranks and pedals were attached to the front-wheel hub of a machine based on Johnson's.
