Tricycles
A tricycle, sometimes abbreviated to trike, is a human-powered (or gasoline or electric motor powered or assisted, or gravity powered) three-wheeled vehicle. Some tricycles, such as cycle rickshaws (for passenger transport) and freight trikes, are used for commercial purposes, especially in the developing world, particularly Africa and Asia. In the West, adult-sized tricycles are used primarily for recreation, shopping, and exercise. Tricycles are favoured by children and senior adults for their apparent stability versus a bicycle; however a conventional trike has poor dynamic lateral stability, and the rider must take care when cornering to avoid tipping the trike over. Unconventional designs such as recumbents have a lower centre of gravity so require less care. History A three-wheeled wheelchair was built in 1655 or 1680 by a disabled German man, Stephan Farffler, who wanted to be able to maintain his mobility. A watch-maker, Farffler created a vehicle that was powere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Recumbents
A recumbent bicycle is a bicycle that places the rider in a laid-back reclining position. Most recumbent riders choose this type of design for ergonomic reasons: the rider's weight is distributed comfortably over a larger area, supported by back and buttocks. On a traditional upright bicycle, the body weight rests entirely on a small portion of the sitting bones, the feet, and the hands. Most recumbent models also have an aerodynamic advantage; the reclined, legs-forward position of the rider's body presents a smaller frontal profile. A recumbent holds the world speed record for a bicycle, and they were banned from racing under the Union Cycliste Internationale (UCI) in 1934, and now race under the banner of the World Human Powered Vehicle Association (WHPVA) and International Human Powered Vehicle Association (IHPVA). Recumbents are available in a wide range of configurations, including: long to short wheelbase; large, small, or a mix of wheel sizes; overseat, underseat, ...

Bicycle Drivetrain Systems
Bicycle drivetrain systems are used to transmit power on bicycles, tricycles, quadracycles, unicycles, or other human-powered vehicles from the riders to the drive wheels. Most also include some type of a mechanism to convert speed and torque via gear ratios. History The history of bicycle drivetrain systems is closely linked to the history of the bicycle. Major changes in bicycle form have often been initiated or accompanied by advances in drivetrain systems. Several early drivetrains used straight-cut gears that meshed directly with each other outside of the hub. Some bicycles have used a double-sided rear wheel, with different-sized sprockets on each side. To change gears, the rider would stop and dismount, remove the rear wheel and reinstall it in the reverse direction. Derailleur systems were first developed in the late 19th century, but the modern cable-operated parallelogram derailleur was invented in the 1950s. * Draisine * Penny-farthing * Safety bicycle Power ...

Bicycle Tire
A bicycle tire is a tire that fits on the wheel of a bicycle or similar vehicle. These tires may also be used on tricycles, wheelchairs, and handcycles, frequently for racing. Bicycle tires provide an important source of suspension, generate the lateral forces necessary for balancing and turning, and generate the longitudinal forces necessary for propulsion and braking. Although the use of a pneumatic tire greatly reduces rolling resistance compared to the use of a rigid wheel or solid tire, the tires are still typically, the second largest source, after wind resistance (air drag), of power consumption on a level road. The modern detachable pneumatic bicycle tire contributed to the popularity and eventual dominance of the safety bicycle. Bicycle tires are also used on unicycles, tricycles, quadracycles, tandem bicycles, hand cycles, bicycle trailers, and trailer bikes. History The first bicycle "tires" were iron bands on the wooden wheels of velocipedes. These ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
:Transportation
Transport (in British English), or transportation (in American English), is the intentional movement of humans, animals, and goods from one location to another. Modes of transport include air, land (rail and road), water, cable, pipeline, and space. The field can be divided into infrastructure, vehicles, and operations. Transport enables human trade, which is essential for the development of civilizations. Transport infrastructure consists of both fixed installations, including roads, railways, airways, waterways, canals, and pipelines, and terminals such as airports, railway stations, bus stations, warehouses, trucking terminals, refueling depots (including fueling docks and fuel stations), and seaports. Terminals may be used both for interchange of passengers and cargo and for maintenance. Means of transport are any of the different kinds of transport facilities used to carry people or cargo. They may include vehicles, riding animals, and pack animals. Vehicles may i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bicycle
A bicycle, also called a pedal cycle, bike or cycle, is a human-powered or motor-powered assisted, pedal-driven, single-track vehicle, having two wheels attached to a frame, one behind the other. A is called a cyclist, or bicyclist. Bicycles were introduced in the 19th century in Europe. By the early 21st century, more than 1 billion were in existence. These numbers far exceed the number of cars, both in total and ranked by the number of individual models produced. They are the principal means of transportation in many regions. They also provide a popular form of recreation, and have been adapted for use as children's toys, general fitness, military and police applications, courier services, bicycle racing, and bicycle stunts. The basic shape and configuration of a typical upright or "safety bicycle", has changed little since the first chain-driven model was developed around 1885. However, many details have been improved, especially since the advent of modern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Edmund Payne
Edmund James "Teddy" Payne (14 December 1863 – 15 July 1914), was an English actor, comedian and singer best known for creating comic roles in a series of extremely successful Edwardian musical comedies. He was often paired with the comic actor George Grossmith, Jr. After about a decade touring and in stock productions, Payne joined the company at the Gaiety Theatre in London, gaining notice for creating a comic character in the musical '' In Town'' (1892). He spent more than two decades at the Gaiety, using his diminutive stature, malleable features, distinctive lisp and comic dance ability to his advantage. His further successes in the 1890s included lovable comic roles in such long-running shows as ''The Shop Girl'' (1894), '' The Circus Girl'' (1896) and '' A Runaway Girl'' (1898). In the new century, he created memorable characters in such hits as '' The Messenger Boy'' (1900), '' The Toreador'' (1902), '' The Orchid'' (1903), ''The Spring Chicken'' (1905), '' The Gi ...

Rational Dress
Victorian dress reform was an objective of the Victorian dress reform movement (also known as the rational dress movement) of the middle and late Victorian era, led by various reformers who proposed, designed, and wore clothing considered more practical and comfortable than the fashions of the time. Dress reformists were largely middle-class women involved in the first wave of feminism in the Western World, from the 1850s through the 1890s. The movement emerged in the Progressive Era along with calls for temperance, women's education, suffrage and moral purity. Dress reform called for emancipation from the "dictates of fashion", expressed a desire to "cover the limbs as well as the torso adequately," and promoted "rational dress". The movement had its greatest success in the reform of women's undergarments, which could be modified without exposing the wearer to social ridicule. Dress reformers were also influential in persuading women to adopt simplified garments for athletic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bike Boom
The bike boom or bicycle craze is any of several specific historic periods marked by increased bicycle enthusiasm, popularity, and sales. Prominent examples include 1819 and 1868, as well as the decades of the 1890s and 1970sthe latter especially in North Americaand the 2010s in the United Kingdom. 1819 The first period which may be called a bicycle craze actually refers to a precursor of the bicycle which was propelled by being pushed along with the feet as the rider straddled the contraption, and had no pedals. This machine was invented by Baron Karl von Drais in Germany, and was called variously a "draisine" (English) or "draisienne" (French) after his name, a "velocipede" from the Latin terms for "fast foot", a "hobby horse", or a " dandy horse", the last name being perhaps the most popular. Drais got a patent for his invention in 1818, and the craze swept Europe and the United States during the summer of 1819 while many manufacturers (notably Denis Johnson of London ...

James Starley
James Starley (21 April 1830 – 17 June 1881) was an English inventor and father of the bicycle industry. He was one of the most innovative and successful builders of bicycles and tricycles. His inventions include the differential gear and the perfection of the bicycle chain drive. Childhood Starley was born in 1830 at Albourne, West Sussex,The Bicycle, UK, 4 November 1953, p8 the son of Daniel Starley, a farmer. He began working on the farm at nine, showing early talent as an inventor by making a rat trap from an umbrella rip and a branch of a willow tree. He ran away from home as a teenager and went to Lewisham, in south London. There he worked as an under-gardener, in his spare time mending watches and creating devices such as a mechanism to allow a duck to get through a hole in a fence, closing a door behind it if a rat tried to follow. Adult life Starley's employer, John Penn, bought a rare and expensive sewing machine. Starley mended it when it broke down and impro ...

Wheelchair
A wheelchair is a chair with wheels, used when walking is difficult or impossible due to illness, injury, problems related to old age, or disability. These can include spinal cord injuries ( paraplegia, hemiplegia, and quadriplegia), cerebral palsy, brain injury, osteogenesis imperfecta, motor neurone disease, multiple sclerosis, muscular dystrophy, spina bifida, and more. Wheelchairs come in a wide variety of formats to meet the specific needs of their users. They may include specialized seating adaptions, individualized controls, and may be specific to particular activities, as seen with sports wheelchairs and beach wheelchairs. The most widely recognized distinction is between motorized wheelchairs, where propulsion is provided by batteries and electric motors, and manual wheelchairs, where the propulsive force is provided either by the wheelchair user or occupant pushing the wheelchair by hand ("self-propelled"), by an attendant pushing from the rear using the handle( ...
