Earliest unverifiable history

There are several early but unverifiable claims for the invention of bicycle-like machines.

The earliest comes from a sketch said to be from 1493 and attributed to Gian Giacomo Caprotti, a pupil of Leonardo da Vinci
Leonardo da Vinci
Leonardo di ser Piero da Vinci was an Italian Renaissance polymath: painter, sculptor, architect, musician, scientist, mathematician, engineer, inventor, anatomist, geologist, cartographer, botanist and writer whose genius, perhaps more than that of any other figure, epitomized the Renaissance...

. Hans-Erhard Lessing recently claimed that this last assertion is a purposeful fraud. However, the authenticity of the bicycle sketch is still vigorously maintained by followers of Prof. Augusto Marinoni, a lexicographer and philologist, who was entrusted by the Commissione Vinciana of Rome with the transcription of da Vinci's Codex Atlanticus
Codex Atlanticus
The Codex Atlanticus is a twelve-volume, bound set of drawings and writings by Leonardo da Vinci, the largest such set; its name indicates its atlas-like breadth. It comprises 1,119 leaves dating from 1478 to 1519, the contents covering a great variety of subjects, from flight to weaponry to...

.

Later, and equally unverifiable, is the contention that Comte de Sivrac developed a célérifère in 1791, demonstrating it at the Palais-Royal in France. The célérifère supposedly had two wheels set on a rigid wooden frame and no steering, directional control being limited to that attainable by leaning. A rider was said to have sat astride the machine and pushed it along using alternate feet. We now know a two-wheeled célérifère never existed (though there were four-wheelers) and it was a misinterpretation by the well known French journalist Louis Baudry de Saunier in 1891.

 effect. This design was welcomed by mechanically minded men daring to balance, and several thousand copies were built and used, primarily in Western Europe and in North America. Its popularity rapidly faded when, partly due to increasing numbers of accidents, some city authorities began to prohibit its use. However in 1866 Paris a Chinese visitor named Bin Chun could still observe foot-pushed velocipedes.

The concept was picked up by a number of British cartwrights; the most notable being Denis Johnson of London

New names were introduced when Johnson patented his machine “pedestrian curricle” or “velocipede,” but the public preferred nicknames like “hobby-horse,” after the children’s toy or, worse still, “dandyhorse,” after the foppish men who often rode them. Johnson's machine was an improvement on Drais's, being notably more elegant: his wooden frame had a serpentine shape

Nevertheless, Drais' velocipede provided the basis for further developments: in fact, it was a draisine which inspired a French metalworker around 1863 to add rotary crank

 often using technologies similar to the draisine, even if the idea of a workable 2-wheel design, requiring the rider to balance, had been dismissed. These new machines had three wheels (tricycles) or four (quadracycles) and came in a very wide variety of designs, using pedals, treadles and hand-cranks, but these designs often suffered from high weight and high rolling resistance.

A similar machine was said to have been produced by Gavin Dalzell of Lesmahagow, circa 1845. There is no record of Gavin ever having laid claim to inventing the machine. It is believed that he copied the idea having recognised the potential to help him with his local drapery business and there is some evidence that he used the contraption to take his wares into the rural community around his home.

, of Kilmarnock in 1869. The design was inspired by the French front-crank velocipede of the Lallement/Michaux type.

1860s and the Michaux or "boneshaker"

The first really popular and commercially successful design was a French one (an example of the style is held in the Museum of Science and Technology (Ottawa)). Initially developed around 1863, it sparked a fashionable craze briefly during 1868-70. Its design was simpler than the Macmillan bicycle; it used rotary cranks and pedals mounted to the front wheel hub. Pedaling made it easier for riders to propel the machine at speed, but the rotational speed limitation arising from stability and comfort concerns would lead to the large front wheel of the "penny farthing". It was difficult to pedal the wheel that was used for steering. The use of metal frames reduced the weight and provided sleeker, more elegant designs, and also allowed mass-production. Different braking mechanisms were used depending on the manufacturer. In England, the velocipede earned the name of "bone-shaker" because of its rigid frame and iron banded wheels that resulted in a "bone-shaking experience for riders."

The velocipede's renaissance began in Paris

 during the late 1860s. Its early history is complex and has been shrouded in some mystery, not least because of conflicting patent claims: all that has been stated for sure is that a French metalworker attached pedals to the front wheel; at present, the earliest year bicycle historians agree on is 1864. The identity of the person who attached cranks is still an open question at International Cycling History Conferences (ICHC). The claims of Ernest Michaux and of Pierre Lallement

, and the lesser claims of rear-pedaling Alexandre Lefebvre, have their supporters within the ICHC community.

Bicycle historian David V. Herlihy documents that Lallement claimed to have created the pedal bicycle in Paris in 1863. He had seen someone riding a draisine in 1862 then originally came up with the idea to add pedals to it. It is a fact that he filed the earliest and only patent for a pedal-driven bicycle, in the USA in 1866. Lallement's patent drawing

 of 1870 destroyed the velocipede market in France, and the "bone-shaker" enjoyed only a brief period of popularity in the United States, which ended by 1870. There is debate among bicycle historians about why it failed in the United States, but one explanation is that American road surfaces were much worse than European ones, and riding the machine on these roads was simply too difficult. Certainly another factor was that Calvin Witty had purchased Lallement's patent, and his royalty demands soon crippled the industry. The UK was the only place where the bicycle never fell completely out of favour.

1870s: the high-wheel bicycle

The high-bicycle was the logical extension of the boneshaker, the front wheel enlarging to enable higher speeds (limited by the inside leg measurement of the rider), the rear wheel shrinking and the frame being made lighter.

Pope lowered the royalty (licensing fee) previous patent owners charged, and took his competitors to court over the patents.

The 1880s and 1890s

The development of the safety bicycle
Safety bicycle
A safety bicycle is a type of bicycle that became very popular beginning in the late 1880s as an alternative to the penny-farthing or ordinary and is now the most common type of bicycle. Early bicycles of this style were known as safety bicycles because they were noted for, and marketed as, being...

 was arguably the most important change in the history of the bicycle. It shifted their use and public perception from being a dangerous toy for sporting young men to being an everyday transport tool for men—and, crucially, women—of all ages.

Aside from the obvious safety problems, the high-wheeler's direct front wheel drive limited its top speed. Accordingly, inventors tried a rear wheel chain drive

. Although Henry Lawson invented a rear-chain-drive bicycle in 1879 with his "bicyclette", it still had a huge front wheel and a small rear wheel. Detractors called it "The Crocodile", and it failed in the market.

 in 1888 had made for a much smoother ride on paved streets; the previous type were quite smooth-riding, when used on the dirt roads common at the time. As with the original velocipede, safety bicycles had been much less comfortable than high-wheelers precisely because of the smaller wheel size, and frames were often buttressed with complicated bicycle suspension

 spring assemblies. The pneumatic tire made all of these obsolete, and frame designers found a diamond pattern to be the strongest and most efficient design.

The chain drive improved comfort and speed, as the drive was transferred to the non-steering rear wheel and allowed for smooth, relaxed and injury free pedaling (earlier designs that required pedalling the steering front wheel were difficult to pedal while turning, due to the misalignment of rotational planes of leg and pedal). With easier pedaling, the rider more easily turned corners.

The pneumatic tire and the diamond frame improved rider comfort but do not form a crucial design or safety feature. A hard rubber tire on a bicycle is just as rideable but is bone jarring. The frame design allows for a lighter weight, and more simple construction and maintenance, hence lower price.

With four key aspects (steering, safety, comfort and speed) improved over the penny farthing, bicycles became very popular among elites and the middle classes in Europe and North America in the middle and late 1890s. It was the first bicycle that was suitable for women, and as such the "freedom machine" (as American feminist Susan B. Anthony

Bicycle historians often call this period the "golden age" or "bicycle craze."

The impact of the bicycle on female emancipation should not be underestimated.

The 20th century


Cycling steadily became more important in Europe over the first half of the twentieth century, but it dropped off dramatically in the United States between 1900 and 1910. Automobiles became the preferred means of transportation. Over the 1920s, bicycles gradually became considered children's toys, and by 1940 most bicycles in the United States were made for children. In Europe cycling remained an adult activity, and bicycle racing, commuting, and "cyclotouring

" were all popular activities. In addition, specialist bicycles for children appeared before 1916.

Bicycles continued to evolve to suit the varied needs of riders. The derailleur developed in France between 1900 and 1910 among cyclotourists, and was improved over time. Only in the 1930s did European racing organizations allow racers to use gearing
Bicycle gearing

; until then they were forced to use a two-speed bicycle. The rear wheel had a sprocket on either side of the hub. To change gears, the rider had to stop, remove the wheel, flip it around, and remount the wheel. When racers were allowed to use derailleurs, racing times immediately dropped.

 appeared, intended for use off-pavement over a variety of surfaces. It was an immediate success, and examples flew off retailers' shelves during the 1980s, their popularity spurred by the novelty of all-terrain cycling and the increasing desire of urban dwellers to escape their surroundings via mountain biking and other extreme sports. These cycles featured sturdier frames, wider tires with large knobs for increased traction, a more upright seating position (to allow better visibility and shifting of body weight), and increasingly, various front and rear suspension designs. By 2000, mountain bike sales had far outstripped that of racing, sport/racer, and touring bicycles.
