Dandy Horse
The dandy horse, an English nickname for what was first called a Laufmaschine ("running machine" in German), then a vélocipède or draisienne (in French and then English), and then a pedestrian curricle or hobby-horse, or swiftwalker, is a human-powered vehicle that, being the first means of transport to make use of the two-wheeler principle, is regarded as the first bicycle. The dandy horse is a foot-propelled vehicle, powered by the rider's feet on the ground instead of the pedals of later bicycles. It was invented by Karl Drais (who called it a ''Laufmaschine'' "running machine" in 1817, and then patented by him in France in February 1818 using the term ''vélocipède''. It is also known as a ''Draisine'' ( in German, a term used in English only for light auxiliary railcars regardless of their form of propulsion), and as a ''draisienne'' ( in French and English. In English, it is also sometimes still known as a velocipede, but that term now also has a broader meaning. H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Draisine Or Laufmaschine, Around 1820
A draisine () is a light auxiliary rail vehicle, driven by service personnel, equipped to transport crew and material necessary for the maintenance of railway infrastructure. The eponymous term is derived from the German inventor Baron Karl Drais, who invented his ''Laufmaschine'' (German for "running machine") in 1817, which was called ''Draisine'' in German (''vélocipède'' or ''draisienne'' in French) by the press. It is the first reliable claim for a practically used precursor to the bicycle, basically the first commercially successful two-wheeled, steerable, human-propelled machine, nicknamed hobby-horse or dandy horse. Later, the name draisine came to be applied only to the invention used on rails and was extended to similar vehicles, even when not human-powered. Because of their low weight and small size, they can be put on and taken off the rails at any place, allowing trains to pass. In the United States, motor-powered draisines are known as speeders while human- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nicéphore Niépce
Joseph Nicéphore Niépce (; 7 March 1765 – 5 July 1833) was a French inventor and one of the earliest History of photography, pioneers of photography. Niépce developed heliography, a technique he used to create the world's oldest surviving products of a photographic process. In the mid-1820s, he used a Camera obscura, primitive camera to produce the View from the Window at Le Gras, oldest surviving photograph of a real-world scene. Among Niépce's other inventions was the Pyréolophore, one of the world's first internal combustion engines, which he conceived, created, and developed with his older brother Claude Niépce. Biography Early life Niépce was born in Chalon-sur-Saône, Saône-et-Loire, where his father was a wealthy lawyer. His older brother Claude (1763–1828) was also his collaborator in research and invention, but died half-mad and destitute in England, having squandered the family wealth in pursuit of non-opportunities for the ''Pyréolophore''.

Velocipede
A velocipede () is a human-powered land vehicle with one or more wheels. The most common type of velocipede today is the bicycle. The term was probably first coined by Karl von Drais in French as ''vélocipède'' for the French translation of his advertising leaflet for his version of the ''Laufmaschine'', also now called a 'dandy horse', which he had developed in 1817. It is ultimately derived from the Latin ''velox'', ''veloc-'' 'swift' + ''pes'', ''ped-'' 'foot'.''Oxford Dictionary of English'', 'velocipede' The term 'velocipede' is today mainly used as a collective term for the different forerunners of the monowheel, the unicycle, the bicycle, the dicycle, the tricycle and the quadracycle developed between 1817 and 1880. Velocipede refers especially to the forerunner of the modern bicycle that was propelled, like a modern tricycle, by cranks, i.e. bicycle pedal, pedals, attached to the front axle before the invention of geared bicycle chain, chains and belt-driven bicycle ...

Outline Of Cycling
Cycling, also known as bicycling or biking, is the activity of riding bicycles or other Human-powered transport, human-powered vehicles with Wheel, wheels, for transportation, recreation, exercise, sport, and other purposes. People who engage in cycling are called cyclists, bikers, or bicyclists. They may wear everyday clothing suited to their destination or specialized cycling attire, sometimes carrying an additional set of clothes. Cycling includes not only traditional two-wheeled bicycles but also unicycles, tricycles, quadricycles, and other human-powered transport, human-powered vehicles (HPVs). Some bicycles are equipped with Electric motor, electric motors (e-bikes) or other forms of Motorized bicycle, motor assistance. Cycling can be done individually or with others. Passengers may ride in front,for instance in the box of a cargo bike, sit on a luggage carrier, or use specially designed seats for children or pets. Some bicycles, such as tandem bicycles or multi-rider pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Balance Bike
A balance bike (or run bike) is a bicycle without pedals that learners propel by pushing their feet against the ground. By allowing children to focus on developing their sense of balance and coordination before introducing pedalling, balance bikes enable independent riding more quickly than training wheels. History Balance bikes descend from the earliest two-wheeled bicycle, a or dandy horse, invented by Karl Drais in 1817. These early balance bikes consisted of a simple wooden frame with two wheels and no pedals, and were designed for adult use. During the twentieth century, children typically learned to ride a bicycle with lateral training wheels. In 1997, German designer Rolf Mertens introduced the first commercially produced (running bike) under the brand KOKUA Bikes. Children's balance bikes quickly gained popularity in Europe in the 2000s and spread elsewhere in the world by the early 2010s. Balance bikes are now a common tool used to teach young children how to ride a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bicycle Pedal
The pedal is the part of a bicycle that the rider pushes with their foot to propel the vehicle. It provides the connection between the cyclist's foot or Cycling shoe, shoe and the Crankset, crank allowing the leg to turn the bottom bracket spindle and propel the bicycle's wheels. A pedal usually consists of a axle, spindle that threads into the end of the crank, and a body on which the foot rest is attached, that is free to rotate on Bearing (mechanical), bearings with respect to the spindle. Pedals were initially attached to cranks connecting directly to the driven (usually front) wheel. The safety bicycle, as it is known today, came into being when the pedals were attached to a crank driving a sprocket that transmitted power to the driven wheel by means of a roller chain. Types Just as bicycles come in many varieties, there are different types of pedals to support different types of cycling. Flat and platform Traditionally, platform pedals were pedals with a relatively large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crank (mechanism)
A crank is an arm attached at a right angle to a rotating shaft by which circular motion is imparted to or received from the shaft. When combined with a connecting rod, it can be used to convert circular motion into reciprocating motion, or vice versa. The arm may be a bent portion of the shaft, or a separate arm or disk attached to it. Attached to the end of the crank by a pivot is a rod, usually called a connecting rod (conrod). The term often refers to a human-powered crank which is used to manually turn an axle, as in a bicycle crankset or a brace and bit drill. In this case a person's arm or leg serves as the connecting rod, applying reciprocating force to the crank. There is usually a bar perpendicular to the other end of the arm, often with a freely rotatable handle or pedal attached. Examples Familiar examples include: Hand-powered cranks * Spinning wheel * Mechanical pencil sharpener * Fishing reel and other reels for cables, wires, ropes, etc. *Starti ...

Rotary Motion
Rotation or rotational/rotary motion is the circular movement of an object around a central line, known as an ''axis of rotation''. A plane figure can rotate in either a clockwise or counterclockwise sense around a perpendicular axis intersecting anywhere inside or outside the figure at a ''center of rotation''. A solid figure has an infinite number of possible axes and angles of rotation, including chaotic rotation (between arbitrary orientations), in contrast to rotation around a axis. The special case of a rotation with an internal axis passing through the body's own center of mass is known as a spin (or ''autorotation''). In that case, the surface intersection of the internal ''spin axis'' can be called a ''pole''; for example, Earth's rotation defines the geographical poles. A rotation around an axis completely external to the moving body is called a revolution (or ''orbit''), e.g. Earth's orbit around the Sun. The ends of the external ''axis of revolution'' can be ...

Denis Johnson (inventor)
Denis Johnson ( – 25 December 1833) was an English coachmaker who worked on Long Acre, London, England. He was a pioneer bicycle-maker. Biography Johnson was married to Mary Newman in St Anne's Church, Soho in 1792 and they had two daughters. He worked out of 75 Long Acre for about 15 years from 1818. Johnson continued as a coachmaker until he died on Christmas Day 1833. The family business continued to trade here until 1867. Bicycle maker Johnson created an improved version of the German Karl Drais's Draisine, the archetypal bicycle. Johnson's pedestrian curricle was patented in London in December 1818, becoming Britain's first bicycle. It featured an elegantly curved wooden frame, allowing the use of larger wooden wheels. Several parts were made of metal, which allowed the vehicle to be lighter than the continental version. Although Johnson referred to his machine as a ‘pedestrian curricle’, it was formally referred to as a ‘velocipede’, and popularly as a ...
