Repeated cycling seems to harden the skin in the crotch for male cyclists, who should not have to resort to the remedies recommended by TOM SIMPSON: ice water baths or cocaine lotions to deaden the nerves. SAFETY BICYCLES A type of bike born of a spate of inventions in the 1870s and 1880s as designers attempted to improve on the HIGH-WHEELER by making the bike more stable and introducing rear-wheel drive. The definitive safety bicycle was produced in 1885 with the launch of the Rover designed by JAMES STARLEY. Starley’s third model for the Rover had the diamond frame, rear chain drive—the bush-roller chain as we know it today had been invented in 1880—and direct front-wheel steering that now define most bikes.

What followed was a constant search for improvement in any area where mechanics came into play, from industry to personal transport, and a wide variety of cycle designs were patended, many for tricycles and quadricycles, none of which caught on. In the early 1840s KIRKPATRICK MACMILLAN and the Frenchman Alexandre Lefebvre both produced rear-wheel-driven machines that never became popular; instead the HIGH-WHEELER took over before the first SAFETY BICYCLES were produced in the 1880s, with the definitive pattern set by JAMES STARLEY’s Rover in 1885. Radical variations on this basic bike design, truly established at the end of the 19th century, have been relatively rare. The Moulton small-wheeler from the 1960s is one departure that has enjoyed enduring popularity.

A drop-frame version was made for ladies to accommodate long skirts. So many people rode the hobby horses that they were banned from pavements in London; the craze spread to America, pushed by Johnson, but eventually died out.

But what happened soon after this put cycling over the top, and it’s the reason I don’t go by the name of “PennyFarthingSnobNYC.” No, I’m not talking about Grover Cleveland’s inauguration. I’m talking about the invention of the “safety bicycle.” The safety bicycle was invented by John Kemp Starley, who just happened to be James Starley’s nephew, and the name of the bike came from the fact you no longer had to perch yourself atop that giant front wheel. The safety bicycle used a chain drive, and the size of the cogs determined the speed of the bicycle. This meant that you could not only use wheels of the same size, but those wheels could also be reasonably sized—like, not taller than you.

This meant that you could not only use wheels of the same size, but those wheels could also be reasonably sized—like, not taller than you. The bicycle was now easy to ride. It handled well. And once Dunlop started making pneumatic tires a few years later, it rode smoothly too. Everything came together. Essentially, the safety bicycle with pneumatic tires is the same thing we’re all riding today. Sure, our bikes are a lot more refined now, but the idea is the same. For the most part, by 1887 they’d nailed it. Once the safety bicycle “dropped,” cycling absolutely exploded. It was the thing to do. Most cyclists, and even many non-cyclists, are aware that professional cycling was once an extremely popular sport in the United States.

My planned ride would take me to my childhood home and the place where I learned to ride a bicycle. Not only that, but the ride would take me along Merrick Road and through Valley Stream, our cycling Bethlehem, along the way. So I took off my tweed reading suit, donned my tweed cycling suit, lubed up my safety bicycle, and off I went. To reach the beach at Far Rockaway, all routes pass through Jamaica. The various ways of reaching Jamaica were fully given in the article describing “A Favorite Century Run to Patchogue.” Jamaica is in Queens. According to the article, to get to Jamaica, I should start in Central Park, leave it at Ninety-sixth Street, head to the ferry house at the foot of East Ninety-ninth Street, and take a ferry to College Point, which is also in Queens.

— TIMO DE RIJK Quoted by Zahid Sardar in The Dutch Bike The story of how the Netherlands became synonymous with cycling would be incomplete without a closer look at the simple machine that inspired it at the turn of the twentieth century: the safety bicycle. Had it not been for widespread, nationwide adoption starting in the 1890s, and the central social role the safety bicycle played over the next 125 years, Dutch cities would probably resemble their neighbors in Western Europe and across the Atlantic, with wide streets, very little cycling infrastructure, and corridors clogged with cars. But just as the Dutch people take their unique bicycle culture for granted, many tend to forget that the vehicle that helped them achieve international notoriety first arrived on their shores with travelers from across the North Sea.

The bakfiets, or “cargo bike” as it is more commonly known in English-speaking countries, is a bicycle (or sometimes tricycle) with a large wooden box attached to the front, originally designed for hauling goods from A to B. Much like the original safety bicycle, which would later become the visual embodiment of Dutch cycle culture, the origins of the bakfiets lie across the North Sea in industrial England. In 1877, John Kemp Starley invented the Coventry Rotary, one of the first chain-drive tricycles, opening up the possibilities for carrying cargo a decade before the safety bicycle hit the streets. Deemed less cumbersome than a horse-and-carriage, these freight trikes were perfect for tradesmen transporting bread, milk, and mail—pretty much anything that needed to be delivered from a business to the customer.

That is to say, these rhetorics were used to produce not only desires for mass-produced goods and services but also an entirely new consumer subject: the cyclist.27 By appealing to the cyclist as a specific type of consumer with unique tastes, bicycle companies could market a wider variety of products to enhance this burgeoning identity. as norcliffe notes, these new consumer subjects were often men: “an enthusiastic male cyclist might have as many as three riding outfits: formal club uniforms were expected for parades, at least until the early 1890s; a more casual outfit with long socks, breeches, and jacket would be worn on regular rides; and light cotton outfits became popular for hot summer days. racers would also have a racing outfit.”28 Many cyclists literally bought into this consumer identity by using bicycles and bicycle accessories to signify their participation in a modern popular culture, yet bicycle manufacturers in the early 1890s were still limited in their ability to transform women into cycling consumer subjects.29 Normalizing the Woman Cyclist Elite women in Europe and the United States were the first to utilize cycling technologies, though most were excluded from riding the high-wheeler, or “ordinary,” bicycle (the one with the big front wheel) as well as most models manufactured prior to the modern “safety” bicycle, which is essentially the bicycle as we know it today.30 “Ordinaries” were incredibly difficult to operate and both clothing and behavioral restrictions made it nearly impossible for women to ride them. Early bicycles were specifically gendered for male use and those women who were the rare exceptions to this rule were mainly “an already suspect class of women: stage performers who used the high wheeler in an act.”31 Tricycle use, on the other hand, was passively supported in the 1880s and the design of the machines made them easier for women to ride: they were both physically easier to operate and many were built to allow for the accompaniment of a male chaperon.32 Women could thus operate tricycles without dramatically challenging the dominant social norms of the period.

Following the mass production of the safety bicycle in the 1890s, many women took up cycling and found in it a renewed sense of freedom and mobility. in the United States, the bicycle’s role in the transformation of gender norms is buttressed by Susan B. anthony’s oft-quoted claim: “The bicycle did more to emancipate women than anything else in the world.”33 Women were certainly not freed by the bicycle, but one cannot overestimate the sense of liberation and empowerment experienced by the first women who transcended the domestic sphere on their own two wheels.

That is to say, while newspapers and magazines gave middle- and upper-class women some space in which to articulate their support for the practice, these outlets regularly published articles and images that clearly mocked women cycling. advertising was a similarly ambiguous format in terms of establishing patterns of representation. patricia Marks, for example, suggests that ads helped to normalize and popularize female bicycling by celebrating the freedom of the new woman, whereas Carla Willard takes a more critical position: she acknowledges that advertising may have dispelled negative perceptions of women bicyclists but it was not meant to empower women socially or politically. rather, bicycle companies were far more concerned with using ads to create a female consumer subjectivity through a watered-down representation of feminism: “The anxious debates about female bicycling were implicit in many brand-product ads, where they were distilled in and quelled by the sales pitch.”45 advertisements, by their very nature, lack the capacity to explain or contextualize the social ramifications of consumer choices, and this, according to Ellen Garvey, was the vital work performed by fiction narratives in popular magazines.46 These stories, she argues, worked in concert with bicycle advertising to create and amplify a larger discourse of consumption around female cycling. as part of an ongoing shift in the publishing industry, the commercial interests of advertising-supported magazines and the bicycle industry resonated to such a degree that seemingly noncommercial narratives either explicitly, or implicitly, promoted bike-riding women in the service of bicycle sales. Female cycling, in other words, had to be made “socially acceptable to sell safety bicycles to a larger market.”47 Bicycling, Garvey argues, was widely used as the centerpiece of magazine fiction that helped to diffuse the potentially disruptive political awareness of the new woman, namely by ensuring readers that bicycling would make women healthier, stronger, and otherwise more fit for motherhood.

It was the so-called safety bicycle, featuring the diamond frame, that pushed the bicycle from being a subcultural toy for bored rich boys to becoming a mainstream form of transport. Before that, “bicycles” were an eclectic collection of bizarre contraptions, the most famous of which was the cumbersome penny-farthing, with its large front wheel and comparatively tiny rear wheel. Several inventors and designers were working on an improvement to the penny-farthing, but the first mass-produced safety bicycle was the Rover, invented by John Kemp Starley in the United Kingdom in 1885. Calling it a “safety bicycle” was the first step in marketing the product to society at large, since the penny-farthing had a reputation as a dangerous machine—and rightly so.

We can thank the penny-farthing for giving us English expressions like taking a header and breakneck speed. It didn’t take long for the design to catch on and be replicated by companies all over the world. (It became so popular in Poland, for example, that the Polish word for bicycle, rower, is a direct derivative of the name Rover.) By a fortunate coincidence, the invention of the safety bicycle coincided with the perfection of the technique required for the art of lithography, which afforded exciting possibilities in both art and marketing. Artists everywhere desperately tried to figure out how to get on board. They looked around for cool new products that they could produce artwork for, and there was the bicycle, waiting for exposure.

His own car, a Daimler, was built there, and while he was sure that the children of Coventry were well cared for, “nobody has attended to them as their fathers are attending to the proud young Double-Six Daimlers.” The automobile industry had grown out of the bicycle industry. One of the first modern-style safety bicycles, invented by Henry John Lawson in 1876, was produced in Coventry. On the back of its success, Lawson went on to try to monopolize the British car industry. At the end of the nineteenth century, he bought up patents for gasoline-powered cars from all over the world, which he hoped to use to extract money from potential car manufacturers.

“When one considers how long the wheel has served in transportation (more than 5,000 years), it seems odd that the first really effective self-propelled wheeled vehicle was developed only about 100 years ago,” he noted, before taking readers through the history of the first “hobby horse” bicycle devised in Germany in 1817, and leading through to the invention of Henry John Lawson’s safety bicycle in Coventry in the 1870s. The key conclusion of Wilson’s piece, however, is this: “When one compares the energy consumed in moving a certain distance as a function of body weight for a variety of animals and machines, one finds that an unaided walking man does fairly well (consuming about 0.75 calories per gram per kilometer), but he is not as efficient as a horse, a salmon, or jet transport.

In Britain, which at the time was second to America in car ownership, with 2 million vehicles on the road (there were 25 million in the States), just 9.1 per cent of commuters used cars, against 22.5 per cent who walked and 19.1 per cent who cycled, while the remainder travelled on public transport. Indeed, commuting by bicycle was the most significant upward trend in British commuting in the first twenty years of the twentieth century. It had begun in the 1880s, after the invention of the ‘safety bicycle’, the first mass-produced example of which was John Kemp Starley’s Rover. The Rover had wheels of almost equal size, springs under its seat, and, from 1890, pneumatic tyres. Its pedals drove the rear wheel via a chain. It looked just like a modern sit-up-and-beg bike and represented a giant leap in technology.

Hitherto the last word in bicycles had been the penny-farthing (named after the disproportion in size between its front and rear wheels), whose riders sat four or five feet off the ground above the front wheel, which they drove by pedals attached to its hub. The diminutive rear wheel trailed behind and acted as a stabilizer. High-wheelers, as they were also known, were unstable, hard to mount and dismount, and dangerous to ride. Indeed, before the appearance of the safety bicycle, cycling was considered an adventure sport rather than a practical form of personal transportation, and the daring young men who practised it borrowed slang from the hunting world – including such phrases as ‘taking a header’*7 – to glamorize their pastime. Although surprisingly fast – in 1891 Fred Osmond covered 23.72 miles in a single hour*8 – penny-farthings were useless for commuting.

“Free to wheel, free to spin out in the glorious country, unhampered by chaperon or even more dispiriting male admirer, the young girl of today can feel the real independence of herself, and while she is building up her better constitution she is developing her better mind.” This was part of a wider social revolution that followed the invention of the first modern-looking bike, the “safety bicycle,” in the late 1880s. With its ease of mounting and pneumatic tires, it was far more practical than the penny farthing, and the safety bicycle became hugely popular in a number of countries—especially for countryside rides along routes as yet unbothered by motor traffic. The British biologist Professor Steve Jones once described the bicycle as the greatest-ever invention to combat genetic disorders, since it gave people who previously tended to only marry those within walking distance of their homes a new opportunity to woo and mate with a far greater variety of potential partners.14 For women, cycling helped loosen the constraining social mores of the Victorian era as well as, more literally, loosen their restrictive Victorian outfits.

These included the use of ball bearings to keep the wheels turning smoothly; tubular steel frames to reduce weight; improved brakes; lightweight metal wheels with wire spokes; freewheel mechanisms that let the rider glide without pedaling; rubber rims around the wheel, which evolved into pneumatic tires; and chain drive of the rear wheel, which solved the problem that direct pedaling of the front wheel interfered with steering. By the late 1880s all these elements had been combined into a recognizably modern design with two equal-sized wheels, known as the safety bicycle. This name was intended to emphasize that bicycles, which had previously been regarded as expensive and dangerous toys for wealthy young men, were now suitable for use by everyone. The new design ushered in a golden age, during which cycling flourished as a leisure activity and a means of truly personal locomotion.

It gives woman a feeling of freedom and self-reliance.” The Century magazine called the bicycle “the great leveller,” suggesting that “it puts the poor man on a level with the rich, enabling him to ‘sing the song of the open road’ as freely as the millionaire.” Advertisement for an early “safety” bicycle. That was overdoing it. But bicycles did have immediate social impact in one area in particular: romance. They broadened people’s social circles, letting cyclists travel beyond their own communities and greatly increasing the number of potential marriage partners. Cycling became a popular social activity that allowed young men and women to escape the oversight of chaperones.

Bicycles had been around for much of the nineteenth century, but until the late 1880s they were primarily used by men, with women often restricted to using two-seater tandem or sociable bikes with a man. The popular penny-farthing bicycle had a large front tire that was directly pedaled by the rider, but it could be hard to control and was too high for the rider’s legs to reach the ground. The invention of the safety bicycle with two tires of similar size and pedals connected to a chain drive—effectively the same style of bicycle in use today —led to a boom in bicycle use in the 1890s and made them accessible to virtually everyone. Women, in particular, gained a new sense of freedom from owning their own bicycles.

The threat they pose is even greater than gimmicky tunnels and redesigned helicopters. 7 The Coming Fight for the Sidewalk Before the automobile transformed urban mobility, another mode of transportation had its own revolutionary effect on the way people moved about. In 1885, John Kemp Starley invented the Rover: a safety bicycle with two wheels of similar size that was much easier to ride than the models that had come before it. When it was fitted with pneumatic tires a few years later, allowing it to ride more smoothly and move at faster speeds, it began to take off in Europe, North America, and beyond. Within a decade, the Stanley Bicycle Show in London featured more than two hundred bicycle makers showcasing 3,000 different models.

With legs trapped behind the handlebar, the common result would be the rider landing squarely on his head (almost all riders were men in during this time, the days before the women's suffrage movement). “Taking a header” was all too often fatal, and so a safer design was sought. In the 1880s, the idea of a chain-driven rear wheel was developed, and the Safety bicycle was born. Safety bicycles most resembled the bicycles of today, except that they had a fixed drivetrain, which meant that whenever the rear wheel was in motion, so were the crank and pedals. This “fixed gear” system allowed you to contribute the strength in your legs to the braking process by resisting the forward movement of the pedals.

The Wright Brothers by David McCullough

From there they continued on to Miamisburg up and over numerous steep hills to see the famous prehistoric Adena Miamisburg Mound, largest of Ohio’s famous conical-shaped reminders of a vanished Native American civilization dating back more than two thousand years. In all they covered thirty-one miles. Bicycles had become the sensation of the time, a craze everywhere. (These were no longer the “high wheelers” of the 1870s and ’80s, but the so-called “safety bicycles,” with two wheels the same size.) The bicycle was proclaimed a boon to all mankind, a thing of beauty, good for the spirits, good for health and vitality, indeed one’s whole outlook on life. Doctors enthusiastically approved. One Philadelphia physician, writing in The American Journal of Obstetrics and Diseases of Women and Children, concluded from his observations that “for physical exercise for both men and women, the bicycle is one of the greatest inventions of the nineteenth century.”

In no time, such was business, they moved to larger quarters down the street to Number 1034 and renamed the enterprise the Wright Cycle Company. Of the two brothers, Orville loved bicycles the most. As an admirer who knew him in later years would say, “Bring up the subject of the shapes of handlebars or types of pedals on early ‘safety bicycles’ and his whole face lights up.” Ever enterprising, incapable of remaining idle, the brothers now turned their off-hours to redoing the interior of 7 Hawthorn Street. They built a new gas fireplace and mantelpiece for the sitting room, redesigned and rebuilt the stairway, refinished all the trim, dressed up rooms with bright new wallpaper, ceilings included, laid new carpets, and with Katharine helping whenever she was home from college.

An out-dated technology cannot be assessed without knowing both the historical context and the semiotics of which it was a part. Bijker illustrates his claim by pointing at the passing from high-wheeled bicycles to safety bicycles. The temptation to dismiss, in hindsight, the high-wheeled bicycle as an inferior and unsafe prototype on the path to evolutionary perfection (the safety bicycle) must be resisted. High-wheeled bicycles were used by upper-class youths, not primarily for transportation but to show off their nerves and skills. The very qualities that made these vehicles unsafe from one perspective made them attractive from the viewpoint of its chief propagators.

No longer could they simply hop in front of a horse trotting along at five miles per hour. And no cane or umbrella or shopping bag was going to slow down an electric streetcar. The electric streetcar in the early 1890s was not, as it turned out, the only new sight taking over Boston’s streets. A two-wheeled invention called a safety bicycle became popular very fast, especially among children. Quiet side streets on warm nights were crowded with people of all ages learning to ride these bikes. The more adventurous ones made their way over to Columbus Avenue, where they learned to ride amid throngs at Colonel Pope’s bicycle rink. There were many models of bicycles, but the more expensive Columbia, which sold for about $100, and the cheaper Lovell Diamond, for about $85, were the most popular.

Jankó’s innovation posed the same difficulty as the Clutsam keyboard: few performers could take their pianos on tour, and many provincial concert halls had no access to innovative instruments. Jankó’s real predicament was deeper. He had invented an interface that, according to many musical authorities, worked too well.29 In sports, as we saw in Chapter One, sheer performance usually wins disputes over style, as the crawl, the safety bicycle, and the reactive resin bowling ball illustrate. But music is not just a proficiency contest. Turn-of-the-century music critics, like many today, deplored the rise of purely technical skill at the expense of musical intelligence and expressiveness. As one skeptic, Constantin Sternberg, wrote in the Musical Courier in 1891, “‘No!

Recumbent bicycles, allowing cyclists to lean back and pedal far more efficiently, were invented in the 193os, only to be excluded from official racing by international cycling authorities. Even here, it was not only official conservatism that kept new designs out of the mainstream. A stable recumbent cycle is heavier and more complex than the familiar safety bicycle that has changed so little in a hundred years. Fairings, aerodynamic shells that cut wind resistance, can make it even more competitive with cars and motorcycles—but also closer to them in bulk and cost. Rules could have been modified to admit recumbent cycles to competition, perhaps in a separate class, and public roads could have been opened to their use by providing dedicated bicycle lanes.

Louis Railroad that he vowed to learn the craft of building highways and eventually laid the groundwork for the Interstate Highway System, which he would not live to see. His youthful interest coincided with the beginning of a keen public awareness of the state of America’s roads. The League of American Wheelmen was initially a cyclists’ lobbying organization. By the 1880s, the dangerous-looking velocipede had become hugely popular, soon replaced by the safety bicycle: $18 could buy you the freedom to tour the country—and if you were a woman, to do so in skirts and bloomers, a sport so liberating that Susan B. Anthony approvingly backed it. But the roads were so execrable that a hundred thousand bicyclists went to Washington to complain. There was little point in owning a set of wheels, they cried out in unison, if wheels could not be used.

However, the “ride to modernity,” as it has been called, can only aptly be described as such in that it paved the way for the automobile.50 Riding a bicycle was, for the most part, a risky undertaking. In Taming the Bicycle, Mark Twain describes his attempt to ride a high wheeler in the 1880s. The adventurous experience is best captured by the concluding words of his essay: “Get a bicycle. You will not regret it, if you live.”51 The arrival of the safety bicycle with its smaller wheels, and the subsequent invention of the pneumatic bicycle tire, eventually brought about the golden age of cycling in the mid-1890s: “People went cycle mad; the bicycle industry appeared to be an El Dorado, and there was a rush to engage in it.”52 But cycling in America soon went out of fashion.

The larger the front wheel, the faster the machine would go, so that in the 1870s the ‘ordinary bicycle’ had a huge front wheel and a tiny rear one – the ‘penny-farthing’ as it was later known. The British inventor James Starley (1831–81) got round these problems by devising the differential gear and the chain drive; his nephew John Kemp Starley (1855–1901) used these devices in 1885 to make the new ‘Rover’ safety bicycle, a far more stable machine than its predecessors. Two years later the Scotsman John Boyd Dunlop (1840–1921) began to market the pneumatic tyre, opening the way for a veritable cycling craze in the following decade. As the price of bicycles fell, sales began to rise. Already in 1911 some 11 per cent of Dutch taxpayers owned a bicycle, and most of them were in the lowest tax bracket, signalling the penetration of the bicycle into the working class.
