Tricycle
A tricycle, sometimes abbreviated to trike, is a Human-powered transport, human-powered (or gasoline or electric motor powered or assisted, or gravity powered) Three-wheeler, 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, the disabled, and senior adults for their apparent stability versus a bicycle; however a Three-wheeler#Two rear, conventional trike may exhibit poor dynamic lateral stability, and the rider should exercise appropriate operating caution when cornering (e.g., with regard to speed, rate of turn, slope of surface) and operating technique (e.g., leaning the body 'into' the turn) to avoid tipping the trike over. Designs such as recumbents or others which place the rider lower relat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Three-wheeler
A three-wheeler is a vehicle with three wheels. Some are motorized tricycles, which may be legally classed as motorcycles, while others are tricycles without a motor, some of which are human-powered vehicles and animal-powered vehicles. Overview Many three-wheelers which exist in the form of motorcycle-based machines are often called trikes and often have the front single wheel and mechanics similar to that of a motorcycle and the rear axle similar to that of a car. Often such vehicles are owner-constructed using a portion of a rear-engine, rear-drive Volkswagen Beetle in combination with a motorcycle front end. Other trikes include that are specially constructed for off-road use. Three-wheelers can have either one wheel at the back and two at the front (2F1R), (for example: Morgan Motor Company) or one wheel at the front and two at the back (1F2R) (such as the Reliant Robin). Due to better safety when braking, an increasingly popular form is the front-steering "tadpole" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Bicycle Wheel
A bicycle wheel is a wheel, most commonly a wire wheel, designed for a bicycle. A pair is often called a wheelset, especially in the context of ready built "off the shelf" performance-oriented wheels. Bicycle wheels are typically designed to fit into the bicycle frame, frame and bicycle fork, fork via Dropout (bicycle part), dropouts, and hold bicycle tires. Invention The first wheel to use the tension in wire wheel, metal spokes was invented by George Cayley, Sir George Cayley to achieve lightness in his 1853 glider. Construction The first bicycle wheels followed the traditions of carriage building: a wooden hub, a fixed steel axle (the bearings were located in the fork ends), wooden spokes and a shrink fitted iron tire. A typical modern wheel has a metal hub, wire tension spokes and a metal or carbon fiber rim which holds a pneumatic rubber tire. Hub A hub is the center part of a bicycle wheel. It consists of an axle, bearing (mechanical), bearings and a hub shell. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Bicycle Tire
A bicycle tire is a tire that fits on the Bicycle wheel, wheel of a bicycle or similar vehicle. These tires may also be used on tricycles, wheelchairs, and handcycles, frequently for Wheelchair racing, racing. Bicycle tires provide an important source of Bicycle suspension, suspension, generate the lateral forces necessary for Bicycle and motorcycle dynamics#Balance, balancing and Bicycle and motorcycle dynamics#Turning, turning, and generate the longitudinal forces necessary for Vehicle propulsion, propulsion and Bicycle brake systems, 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 Drag (physics), 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, tricyc ...

Recumbents
A recumbent bicycle is a bicycle that places the rider in a laid-back reclining position, and often called a human-powered vehicle or HPV, especially if it has an aerodynamic fairing. Recumbents are available in a wide range of configurations, including: long to short wheelbase; large, small, or a mix of wheel sizes; overseat, underseat, or no-hands steering; and rear wheel or front wheel drive. A variant with three wheels is a recumbent tricycle, with four wheels a quadracycle. Recumbents can be faster than upright bicycles, but they were banned by the Union Cycliste Internationale (UCI) in 1934. Recumbent races and records are now overseen by the World Human Powered Vehicle Association (WHPVA), International Human Powered Vehicle Association (IHPVA) and World Recumbent Racing Association (WRRA). Some recumbent riders may 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 tr ...

Stephan Farffler
Stephan Farffler (1633 – October 24, 1689), sometimes spelled Stephan Farfler, was a German watchmaker of the seventeenth century whose invention of a manumotive carriage in 1655 is widely considered to have been the first self-propelled wheelchair. The three-wheeled device is also believed to have been a precursor to the modern-day tricycle and bicycle A bicycle, also called a pedal cycle, bike, push-bike or cycle, is a human-powered transport, human-powered or motorized bicycle, motor-assisted, bicycle pedal, pedal-driven, single-track vehicle, with two bicycle wheel, wheels attached to a .... Farffler, who was either a paraplegic or an amputee, also created a device for turning an hourglass at regular intervals and added chimes to the clocktower of Altdorf bei Nürnberg. the German WiKi says: either paraplegic as a result of an accident when aged three years; others describe him as a human with crippled legs Fabian Zilliken: ''Die Evolution des Fahrrads - Von ...

: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, pipelines, 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 fuel docks and fuel stations), and seaports. Terminals may be used both for the 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 incl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Wheelchair
A wheelchair is a mobilized form of chair using two or more wheels, a footrest, and an armrest usually cushioned. It is used when walking is difficult or impossible to do due to illnesses, injury, disabilities, or age-related health conditions. Wheelchairs provide mobility, postural support, and freedom to those who cannot walk or have difficulty walking, enabling them to move around, participate in everyday activities, and live life on their own terms. Wheelchairs come in a wide variety of formats to meet the specific needs of their users. They may include specialized seating adaptions, and individualized controls, and may be specific to particular activities, as 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 ...

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, the perfection of the bicycle chain drive, and the penny-farthing. 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 ...

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] [Amazon] |
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) ...
