FIRST SAFETY BICYCLE INTRODUCED IN ENGLAND 1860







FIRST SAFETY BICYCLE 
INTRODUCED IN ENGLAND 1860













1418 Giovanni Fontana built the first human powered land vehicle -- it had four wheels and used an endless rope connected via gears to the wheels.

1493 Scetch of bicycle falsely attributed to Leonard da VinciSketches showing a primitive version of a bicycle, purported drawn by Leonardo da Vinci, surfaced in 1974. Further examination of the drawings indicates these are not by da Vinci's hand. The speculation that these are a sketch by a pupil after a lost drawing by da Vinci is also considered false.

An age test was performed, but the library in Milan (belonging to the Vatican) conceals its negative outcome, see http://www.cyclepublishing.com/…/leonardo%20da%20vinci%20bi… . Experts consider the sketches a hoax.

The earliest comes from a sketch said to be from 1534 and attributed to Gian Giacomo Caprotti, a pupil of Leonardo da Vinci
. In 1998 Hans-Erhard Lessing described this as a purposeful fraud.[1][2] 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.[3]

Later, and equally unverified, is the contention that Comte the Sivrac developed a célérifère in 1792, 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.[4] A rider was said to have sat astride the machine and pushed it along using alternate feet. It is now thought that the two-wheeled célérifère never existed (though there were four-wheelers) and it was instead a misinterpretation by the well-known French journalist Louis Baudry de Saunier in 1891.[5][6]

1817 to 1819: the draisine or velocipede

The first verifiable claim for a practically used bicycle belongs to German Baron Karl von Drais, a civil servant to the Grand Duke of Baden in Germany. Drais invented his Laufmaschine (German for "running machine") of 1817 that was called Draisine (English) or draisienne (French) by the press. Karl von Drais patented this design in 1818, which was the first commercially successful two-wheeled, steerable, human-propelled machine, commonly called a velocipede, and nicknamed hobby-horse or dandy horse.[7]

It was initially manufactured in Germany and France. Hans-Erhard Lessing found from circumstantial evidence that Drais' interest in finding an alternative to the horse was the starvation and death of horses caused by crop failure in 1816 ("Eighteen Hundred and Froze to Death," following the volcanic eruption of Tambora in 1815).[8]

On his first reported ride from Mannheim on June 12, 1817, he covered 13 km (eight miles) in less than an hour.[9] Constructed almost entirely of wood, the draisine weighed 22 kg (48 pounds), had brass bushings within the wheel bearings, iron shod wheels, a rear-wheel brake and 152 mm (6 inches) of trail of the front-wheel for a self-centering caster 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.[10]

1820s to 1850s: an era of 3 and 4-wheelers[edit]

Though technically not part of two-wheel ("bicycle") history, the intervening decades of the 1820s-1850s witnessed many developments concerning human-powered vehicles often using technologies similar to the draisine, even if the idea of a workable two-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. However, Willard Sawyer in Dover successfully manufactured a range of treadle-operated 4-wheel vehicles and exported them worldwide in the 1850s.[11]

1860s and the Michaux or "boneshaker"[edit]
The first really popular and commercially successful design was French. An example is at the Museum of Science and Technology, Ottawa.[12] 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 of this design created stability and comfort concerns which 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.

New York company Pickering and Davis invented this pedal-bicycle for ladies in 1869.[13][14]
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 US in 1866. Lallement's patent drawing shows a machine which looks exactly like Johnson's draisine, but with the pedals and rotary cranks attached to the front wheel hub, and a thin piece of iron over the top of the frame to act as a spring supporting the seat, for a slightly more comfortable ride.

By the early 1860s, the blacksmith Pierre Michaux, besides producing parts for the carriage trade, was producing "vélocipède à pédales" on a small scale. The wealthy Olivier brothers Aimé and René were students in Paris at this time, and these shrewd young entrepreneurs adopted the new machine. In 1865 they travelled from Paris to Avignon on a velocipede in only eight days. They recognized the potential profitability of producing and selling the new machine. Together with their friend Georges de la Bouglise, they formed a partnership with Pierre Michaux, Michaux et Cie ("Michaux and company"), in 1868,

avoiding use of the Olivier family name and staying behind the scenes, lest the venture prove to be a failure. This was the first company which mass-produced bicycles, replacing the early wooden frame with one made of two pieces of cast iron bolted together—otherwise, the early Michaux machines look exactly like Lallement's patent drawing. Together with a mechanic named Gabert in his hometown of Lyon, Aimé Olivier created a diagonal single-piece frame made of wrought iron which was much stronger, and as the first bicycle craze took hold, many other blacksmiths began forming companies to make bicycles using the new design. Velocipedes were expensive, and when customers soon began to complain about the Michaux serpentine cast-iron frames breaking, the Oliviers realized by 1868 that they needed to replace that design with the diagonal one which their competitors were already using, and the Michaux company continued to dominate the industry in its first years.
