Engineering Report

Background

The modern diamond frame `safety' bicycle was the final outcome of an enormously varied  range of design configurations produced in the later part of the 19th century. One of these was (so far as is now known) the first semi-recumbent1 bicycle, the Normal Bicyclette, made in Ghent by Challand sometime before 18952. However, the reign of the safety bicycle was already supreme by 1890; the later attempts at introducing recumbent designs were greeted with criticism and ridicule: `A crazy effort,' said Britain's "The Cyclist" of  a quite viable semi-recumbent machine made by an American named Brown.  In  1914  the  French  firm Peugeot commenced manufacture of a semi-recumbent model, but the event was eclipsed by the onset of the Great War.

One or two recumbents were made in the 1920s, but it was not until the 1930s that a series of racing semi-recumbents brought out in France and called Velocars (Horizontal Bicycles in Britain) attained  tragically brief notoriety. Riding a Velocar, a relatively unknown  racing  cyclist,  François Fauré, defeated the then World Champion, Lemoire, in a 4 km pursuit race, and also broke many track records established on conventional machines.

The  International  Cycling  Union, which  controlled  world  bicycling, showed  typical  bureaucratic  perspicacity by greeting these events with  a  total  ban  in  organised competition for all unconventional design types. Lost at a stroke was the incentive for experimentation through participation in the racing arena.
