When motor fuel and cars became available and affordable again well after the Second World War ended , the bicycle in many Western countries was reduced to being used by children and by what were seen as fringe groups. In the third world, the bicycle was a necessity for anyone who could afford one.

In most of these countries and especially in China, the proportion of person-trips and even of freight moved by bicycle were and possibly still are far higher than that taken by the railroads and road traffic. A modern bicycle boom started in the United States in around , for reasons difficult to discern. It followed rather closely the end of a two- year competition in the design of human-powered vehicles organized by the author that created considerable public interest at the time, so that he is tempted to puff himself up to take credit, just as the cock crows at the dawn he has obviously caused.

Sales of bicycles rose rapidly to ex- ceed comfortably the annual sales of automobiles. The downloaders were over- whelmingly middle-class, college and professional people, U. But in , at the time the enthusiasm for lightweight road bikes in the United States was increasing, a few enthusiasts in Marin County, California, began experimenting with old Schwinn clunkers for downhill off-road racing Berto Others had done so in different countries before this, but they had not started a move- ment.

Berto interviewed nine then-young men who, in this small area of California, continued experimenting throughout the s with config- urations of bicycles that gave advantages first for fast purely downhill travel and later for cross-country and uphill riding.

Several started companies to produce the designs they developed. This second boom in popularity of bicycles has been different in character from the road-bike boom, because a far higher proportion of the bikes downloadd has been used to a significant extent.

Perhaps most have not in fact been used for off-road recreation but have been seen as an ex- tremely practical bike for negotiating rough urban streets in commuting or shopping use.

They have left far behind their original heavy clunker image and have become high-tech lightweights. They have reached extraordinary levels of sophistication, many having front and rear suspension, wide- range twenty-seven-speed gears, hydraulic disk brakes, and frames made from aluminum, titanium, or carbon fiber. The technology developed for so-called mountain bikes is leading the bicycle industry generally.

How- ever, at the time of writing the sales of ATBs have peaked and are falling somewhat.

Recumbents One reason for discussing recumbents rather than tandems, folding bicy- cles, pedicabs, or goods transporters is that most modern record-breaking machines are recumbents. Another is that greater safety can result from the use of the recumbent riding position in highway bicycles.

In addition, what we know of the history of this variant form might help to illustrate the past and present character of the cycle industry. Many early cycles particularly tricycles used the semirecumbent position. The pedal-force reaction is taken not by the weight of the body or, when that is exceeded, by pulling down on the handlebars , but by the backrest. Challand called it the Normal Bicyclette.

By this time orthodoxy rested firmly with the traditional safety bicycle, and the derision that had successively greeted the Draisienne, the velocipede, and the safety had been forgotten. The weight 30 lb. The mounting and dismounting are easy, and this is a fine coasting machine, the great wheel-base making very smooth riding.

The machine runs light and is a good hill- climber, and it is only fair to say that the general action of this queerest of all attempts at cycle improvement is easy and good—far better than its appearance indicates.

Wales in Sketched by Frank Whitt.

From the advertisement of a licensor. Recumbents were more successful in Europe. Some heavier devices were available earlier for tricycles. The Sturmey-Archer three-speed hub was the predominant type, as it still is in many parts of the world Hadland , but there were many competitors at the turn of the century.

The derailleur or shifting-chain gear was developed in France and Britain in but was not popular. It was developed by degrees in Europe and was eventually accepted for racing in the s Berto, Shepherd, and Henry Undoubtedly, much more will be discovered about the history of the modern traditional single-rider bicycle, and unrecognized inventors will receive the honor due them.

Inquiring readers can find much more history than we have space for here in the excellent books referenced and those listed at the end of the chapter. Riding with my elder brothers and mother and father was an important part of growing up. Going with my schoolboy friends to see local bomb damage and downed planes, to visit local towns for attractions such as swimming holes, and to plan increasingly longer trips ending with a 1,mile 1,km tour into Scotland in were all liberating and, one hopes, character-forming activities.

The camaraderie of European bicyclists everywhere made trips of any length very enjoyable.

Such machines were offered because riders accustomed to front-drive machines did not always take kindly to the rear-drive safeties.

This new edition of the bible of bicycle builders and bicyclists provides just about everything you could want to know about the history of bicycles, how human beings propel them, what makes them go faster, and what keeps them from going even 4.
