Human-powered Transport
Human-powered transport is the transport of person(s) and/or goods using human muscle power. Unlike animal-powered transport, human-powered transport has existed since time immemorial in the form of walking, running and swimming. Modern technology has allowed machines to enhance human-power. Although motorization has increased speed and load capacity, many forms of human-powered transport remain popular for reasons of cost, convenience, leisure, physical exercise, and environmentalism. Human-powered transport is sometimes the only type available, especially in underdeveloped or inaccessible regions.

Climbing
Climbing is the activity of using one's hands, feet, or any other part of the body to ascend a steep topographical object that can range from the world's tallest mountains (e.g. the eight thousanders), to small boulders. Climbing is done for locomotion, sporting recreation, and for competition, and is also done in trades that rely on ascension; such as emergency rescue and military operations. Climbing is done indoors and outdoors and on natural (e.g. rock and ice) and artificial surfaces. Professional mountain guides or rock climbing guides (e.g. the UIAGM), were a significant element in developing the popularity of the sport in the natural environment, and remain so today. Since the 1980s, the development of competition climbing and the availability of artificial climbing walls have dramatically increased the popularity of rock climbing as a sport and led to the emergence of professional rock climbers, such as Wolfgang Güllich, Chris Sharma, Lynn Hill and Ca ...

Recumbent Bicycle
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 ...

Upright Bicycle
Body relative directions (also known as egocentric coordinates) are geometrical orientations relative to a body such as a human person's. The most common ones are: left and right; forward(s) and backward(s); up and down. They form three pairs of orthogonal axes. Traditions and conventions Since definitions of left and right based on the geometry of the natural environment are unwieldy, in practice, the meaning of relative direction words is conveyed through tradition, acculturation, education, and direct reference. One common definition of up and down uses gravity and the planet Earth as a frame of reference. Since there is a very noticeable force of gravity acting between the Earth and any other nearby object, down is defined as that direction which an object moves in reference to the Earth when the object is allowed to fall freely. Up is then defined as the opposite direction of down. Another common definition uses a human body, standing upright, as a frame of reference. In ...

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] |
Skateboards
A skateboard is a type of sports equipment used for skateboarding. They are usually made of a specially designed 7-8 ply maple plywood deck and polyurethane wheels attached to the underside by a pair of skateboarding trucks. The skateboarder moves by pushing with one foot while the other foot remains balanced on the board, or by pumping one's legs in structures such as a bowl or half pipe. A skateboard can also be used by simply standing on the deck while on a downward slope and allowing gravity to propel the board and rider. If the rider's leading foot is their right foot, they are said to ride "goofy". The two main types of skateboards are the longboard and the shortboard. The shape of the board is also important: the skateboard must be concaved to perform tricks. History Skateboarding started in California in the 1950s. The first skateboards were made from roller skates attached to a board. Skateboarding gained in popularity because of surfing: in fact, skateboarding wa ...

Red DX Surrey
Red is the color at the long wavelength end of the visible spectrum of light, next to orange and opposite violet. It has a dominant wavelength of approximately 625–740 nanometres. It is a primary color in the RGB color model and a secondary color (made from magenta and yellow) in the CMYK color model, and is the complementary color of cyan. Reds range from the brilliant yellow-tinged scarlet and vermillion to bluish-red crimson, and vary in shade from the pale red pink to the dark red burgundy. Red pigment made from ochre was one of the first colors used in prehistoric art. The Ancient Egyptians and Mayans colored their faces red in ceremonies; Roman generals had their bodies colored red to celebrate victories. It was also an important color in China, where it was used to color early pottery and later the gates and walls of palaces. In the Renaissance, the brilliant red costumes for the nobility and wealthy were dyed with kermes and cochineal. The 19th century brought ...

Trikke HPV
The Trikke works by shifting body weight The Trikke ( ; also known as a wiggle scooter, scissor scooter, carver scooter, and Y scooter) is a chainless, pedalless, personal vehicle with a three-wheel frame. The rider stands on two foot platforms above the two rear wheels and steers the vehicle with handlebars attached to the lone front wheel. The cambering system is designed to provide a stable, three-point platform that lets the rider lean into turns while all three wheels remain in contact with the ground. There are several variations of the Trikke, from body-powered fitness machines, to battery-powered transportation and personal mobility vehicles. Brand name Trikkes are manufactured by the company Trikke Tech based in Buellton, California Buellton is a small city in Santa Barbara County, California, United States. It is located in the Santa Ynez Valley, west of Solvang. The population was 5,161 at the 2020 census, up from 4,828 at the 2010 census. Located at the junc ...

Cross-country Skiing
Cross-country skiing is a form of skiing where skiers rely on their own locomotion to move across snow-covered terrain, rather than using ski lifts or other forms of assistance. Cross-country skiing is widely practiced as a sport and recreational activity; however, some still use it as a means of transportation. Variants of cross-country skiing are adapted to a range of terrain which spans unimproved, sometimes mountainous terrain to groomed courses that are specifically designed for the sport. Modern cross-country skiing is similar to the original form of skiing, from which all skiing disciplines evolved, including alpine skiing, ski jumping and Telemark skiing. Skiers propel themselves either by striding forward (classic style) or side-to-side in a skating motion (skate skiing), aided by arms pushing on ski poles against the snow. It is practised in regions with snow-covered landscapes, including Europe, Canada, Russia, the United States, Australia and New Zealand. Compet ...

Inline Skating
Inline skating is a multi-disciplinary sport and can refer to a number of activities practiced using inline skates. Inline skates typically have two to five polyurethane wheels depending on the style of practice, arranged in a single line by a metal or plastic frame on the underside of a boot. The in-line design allows for greater speed and maneuverability than traditional (or "quad") roller skates. Following this basic design principle, inline skates can be modified to varying degrees to accommodate niche disciplines. Inline skating is commonly referred to by the proprietary eponym ''rollerblading'', or just ''blading'', due to the popular brand of inline skates, Rollerblade. History An inline skate appeared in a Paris patent in 1819, but were overtaken in popularity by quad skates. The German branch of SKF developed and produced inline-skates in 1978 with wheels for hockey or for the street. The product was stopped after one year as the management did not want a consume ...
