Flying Pigeon
Flying Pigeon () is a Chinese publicly owned bicycle company based in Tianjin. Since 1950, more than 500 million Flying Pigeon PA-02 bicycles have been made, and as of 2007, more than any other model of vehicle. The next closest vehicle model is the Honda Super Cub motorcycle, which passed 60 million in 2008, and 100 million in 2017. History In 1936, a Japanese businessman built the Changho Works factory in Tianjin, and started to make "Anchor" bicycles. The brand name was changed to "Victory", and then renamed to "Zhongzi". After the Communists led by Chinese Communist Party chairman Mao Zedong came to power in 1949, the bicycle industry was revived. In April 1949, Communist Party secretary Liu Shaoqi paid a visit to the factory and commanded that it become the first bicycle manufacturer in New China. Their workers were tasked to build a generation of strong, durable, light, and beautiful bicycles for the New China. On July 5, 1950, the first Flying Pigeon bicycle was p ...

State Ownership
State ownership, also called government ownership and public ownership, is the ownership of an industry, asset, or enterprise by the state or a public body representing a community, as opposed to an individual or private party. Public ownership specifically refers to industries selling goods and services to consumers and differs from public goods and government services financed out of a government's general budget. Public ownership can take place at the national, regional, local, or municipal levels of government; or can refer to non-governmental public ownership vested in autonomous public enterprises. Public ownership is one of the three major forms of property ownership, differentiated from private, collective/cooperative, and common ownership. In market-based economies, state-owned assets are often managed and operated as joint-stock corporations with a government owning all or a controlling stake of the company's shares. This form is often referred to as a stat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deng Xiaoping
Deng Xiaoping (22 August 1904 – 19 February 1997) was a Chinese revolutionary leader, military commander and statesman who served as the paramount leader of the China, People's Republic of China (PRC) from December 1978 to November 1989. After Chairman of the Chinese Communist Party, CCP chairman Mao Zedong's Death and state funeral of Mao Zedong, death in 1976, Deng gradually rose to supreme power and led China through a series of Chinese economic reform, far-reaching market-economy reforms earning him the reputation as the "Architect of Modern China". He contributed to China becoming the List of countries by GDP (nominal), world's second largest economy by GDP nominal in 2010. Born in the province of Sichuan in the Qing dynasty, Deng studied and worked in France in the 1920s, where he became a follower of Marxism–Leninism and joined the Chinese Communist Party (CCP) in 1924. In early 1926, Deng travelled to Moscow to study Communist doctrines and became a political commi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chain Case
A gear case, also known as a chain case or chainguard, is an enclosure for the bicycle chain and sprocket assemblages commonly employed by utility bicycles. It serves to protect the cyclist from being soiled or trapped in the chain rings and tends to fully enclose the drive train. It may also contain an oil bath to keep the chain lubricated. Modern examples are usually moulded in plastic. Similar devices may be found in connection with chains used on larger vehicles and machinery. Gallery See also * Luggage carrier A luggage carrier, also commonly called a rack, is a device attached to a bicycle to which cargo or panniers can be attached. This is popular with utility bicycles and touring bicycles. Bicycle luggage carriers may be mounted on the front or r ...

Mudguard
A mudflap or mud guard is used in combination with the vehicle fender to protect the vehicle, passengers, other vehicles, and pedestrians from mud and other flying debris thrown into the air by the rotating tire. A mudflap is typically made from a flexible material such as rubber that is not easily damaged by contact with flying debris, the tire, or the road surface. On bicycles the mudflap is called a spoiler. It helps keep the rider(s) cleaner. Mudflaps can be large rectangular sheets suspended behind the tires, or may be small molded lips below the rear of the vehicle's wheel wells. Mudflaps can be aerodynamically engineered, utilizing shaping, louvers or vents to improve airflow and lower drag. While some flaps are plain, in the colour of rubber, many contain company logos, other art or sometimes advertisements. Another is the mudflap girl, a woman's silhouette. In the United States, there are mudflap regulations that vary from state to state. Aerodynamic Aerodyna ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gear Inches
Gear inches is one of several relative measures of bicycle gearing, giving an indication of the mechanical advantage of different gears. Values for 'gear inches' typically range from 20 (very low gearing) via 70 (medium gearing) to 125 (very high gearing); as in a car, low gearing is for going up hills and high gearing is for going fast. 'Gear inches' is actually the diameter in inches of the drive wheel of a penny-farthing bicycle with equivalent gearing. Origin of the term When the high wheeler or penny-farthing was the "ordinary" bicycle form, the comparative diameter in inches of the driven wheel was an indication of relative speed and effort. A 60-inch wheel propelled a bicycle faster than a 50-inch wheel when both were cranked at the same cadence. The technology of the high wheeler imposed a natural limit—a 60-inch wheel was about the maximum size that could be straddled by ordinary sized legs. When "safeties" replaced "ordinaries," chains and sprockets allowed small whee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bicycle Frame
A bicycle frame is the main component of a bicycle, onto which wheels and other components are fitted. The modern and most common frame design for an upright bicycle is based on the safety bicycle, and consists of two triangles: a main triangle and a paired rear triangle. This is known as the ''diamond frame''. Frames are required to be strong, stiff and light, which they do by combining different materials and shapes. A frameset consists of the frame and fork of a bicycle and sometimes includes the headset and seat post. Frame builders will often produce the frame and fork together as a paired set. Variations Besides the ubiquitous diamond frame, many different frame types have been developed for the bicycle, several of which are still in common use today. Diamond In the diamond frame, the main "triangle" is not actually a triangle because it consists of four tubes: the head tube, top tube, down tube and seat tube. The rear triangle consists of the seat tube joined by p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Westwood Rim
The Westwood rim style of cycle rim used on bicycles was one of the original steel rim designs, developed during or before 1891 by Frederick Westwood of Birmingham. Bowden brakes and cables designed for use with this rim were introduced in 1896. Westwood rims have also been found ideal for use with drum brakes. They were last used on the roadster cycles found in Britain up to the 1980s and still common in South and East Asia and Africa and becoming common once again in Europe. Westwood rims have rounded sides, so they are not suitable for use with caliper brakes. Westwood rims features a wide single-wall cross section, the inside circumference of the rim has a contoured section shape to aid with strength. Today Westwood profile rims found in the West are mostly used in drum brake system roadsters and, to a lesser degree, in bicycles with coaster brake systems. Variations and sizes Raleigh Bicycle Company developed a variation that combined the rod braking surfaces of Westwo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ISO 5775
ISO 5775 is an international standard for labeling the size of bicycle tires and rims. The system used was originally developed by the European Tyre and Rim Technical Organisation (ETRTO). It is designed to make tire sizing consistent and clear. It replaces overlapping informal systems that ambiguously distinguished between sizes. For example, at least 6 different "26 inch" sizes exist (just by American notation), and "27 inch" wheels have a larger diameter than American "28 inch" (French "700C") wheels. The Japanese Industrial Standards Committee also cooperates with ISO 5775. The corresponding Japanese standards are JIS D 9112 for tires and JIS D 9421 for rims. Tires Wired-edge tires Wired-edge tires can be mounted on straight-side or crochet-type (aka hook bead) rims. Crochet-type rims are not the same as hooked-bead rims. Such tires are designated with their ''nominal width'' and their ''nominal rim diameter'', separated by a hyphen (-). Both are measured in millim ...

Dynamo
"Dynamo Electric Machine" (end view, partly section, ) A dynamo is an electrical generator that creates direct current using a commutator. Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later electric-power conversion devices were based, including the electric motor, the alternating-current alternator, and the rotary converter. Today, the simpler alternator dominates large scale power generation, for efficiency, reliability and cost reasons. A dynamo has the disadvantages of a mechanical commutator. Also, converting alternating to direct current using rectifiers (such as vacuum tubes or more recently via solid state technology) is effective and usually economical. History Induction with permanent magnets The Faraday disk was the first electric generator. The horseshoe-shaped magnet ''(A)'' created a magnetic field through the disk ''(D)''. When the disk was turned, this induced an elect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ford Model T
The Ford Model T is an automobile that was produced by Ford Motor Company from October 1, 1908, to May 26, 1927. It is generally regarded as the first affordable automobile, which made car travel available to middle-class Americans. The relatively low price was partly the result of Ford's efficient fabrication, including assembly line production instead of individual handcrafting. It was mainly designed by an American ( Childe Harold Wills) and two Hungarian engineers (Joseph A. Galamb, Eugene Farkas). The Model T was colloquially known as the "Tin Lizzie", "Leaping Lena" or "flivver". The Ford Model T was named the most influential car of the 20th century in the 1999 Car of the Century competition, ahead of the BMC Mini, Citroën DS, and Volkswagen Beetle. Ford's Model T was successful not only because it provided inexpensive transportation on a massive scale, but also because the car signified innovation for the rising middle class and became a powerful symbol of t ...

Roadster (bicycle)
A roadster bicycle is a type of utility bicycle once common worldwide, and still common in Asia, Africa, Latin America, and some parts of Europe. During the past few decades, traditionally styled roadster bicycles have regained popularity in the Western world, particularly as a lifestyle or fashion statement in an urban environment. Design and variants There were three basic variants of the roadster. Roadster Gents' roadster The classic gents' roadster, AKA the English roadster, has a lugged brazed steel diamond frame, rod-actuated brakes and of late, cable operated drum brake systems have been widely produced for the European market, upright North Road handlebars, a single gear ratio or three- or five-speed hub gears, a chaincase, steel mudguards, steel cranks, ( ISO 635) wheels, Westwood rims, and often a Sturmey-Archer hub dynamo. Roadsters are built for durability above all else and no serious attempt is made to save weight in their design or construction, roadster ...
