Ice Cycle
An ice cycle, ice bike, or icycle is a bicycle adapted for use on ice, usually by replacing the front wheel with an ice skate. Versions exist with and without additional skates to provide lateral stability, that have been based on upright and recumbent bikes, and that have been used for racing. Ice cycles have been in use since at least the 1890s, and theory predicts that a bicycle with a front skate can exhibit riderless self-stability similar to the same bicycle with a front wheel. At least one example has been made with both the front and the rear wheels replaced by skates.

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] |
Ice Skate
Ice skates are metal blades attached underfoot and used to propel the bearer across a sheet of ice while ice skating. The first ice skates were made from leg bones of horse, ox or deer, and were attached to feet with leather straps. These skates required a pole with a sharp metal spike that was used for pushing the skater forward, unlike modern bladed skates. Modern skates come in many different varieties, which are chosen depending on the nature of the requirements needed for the skating activity. They are worn recreationally in ice rinks or on frozen bodies of water across the globe and are used as footwear in many sports, including figure skating, bandy, ice hockey, ringette, rink bandy, rinkball, speed skating and tour skating. History According to a study done by Federico Formenti, University of Oxford, and Alberto Minetti, University of Milan, Finns were the first to develop ice skates some 5,000 years ago from animal bones. This was important for the Finnish populations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mechanix Illustrated
''Mechanix Illustrated'' was an American printed magazine that was originally published by Fawcett Publications. Its title was founded in 1928 to compete against the older ''Popular Science'' and ''Popular Mechanics''. Billed as "The How-To-Do Magazine," ''Mechanix Illustrated'' (''MI'') aimed to guide readers through various projects from home improvements and advice on repairs to "build-your-own (sports car, telescope, helicopter, etc)." It was headquartered in New York City. History and profile From its debut in 1928, it went through a number of permutations over the years, being called at various points in its life, ''Modern Mechanics and Inventions'', ''Modern Mechanix and Inventions'', ''Modern Mechanix'', ''Mechanix Illustrated'', ''Home Mechanix'', and, in its final incarnation, ''Today's Homeowner''. Although it featured many how-to articles, the most eagerly awaited and read features were Tom McCahill's monthly automobile tests which ran from the late 1940s to the earl ...

Upright Bicycle
Body relative directions (also known as egocentric coordinates) are orientation (geometry), 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 Earth, 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 free-fall, fall freely. Up is then defined as the opposite direction of down. Another common definition uses a human body, stand ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Tuberosity of the ischium, sitting bones, the feet, and the hands. Most recumbent models also have an aerodynamics, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Imperial College London
Imperial College London (legally Imperial College of Science, Technology and Medicine) is a public research university in London, United Kingdom.

Cold-weather Biking
Cold-weather biking, cold-weather cycling, or winter biking is the use of a bicycle during months when roads and paths are covered with ice, slush and snow. Cold weather cyclists face a number of challenges in near or below freezing temperatures. Urban commuters on city streets may have to deal with " ow, slush, salt, and sand", which can cause rust and damage to metal bike components. Slush and ice can jam derailleurs. Some cyclists may bike differently in winter, by "slow ngdown on turns and brak nggradually" in icy conditions. Gaining traction on snow and ice-covered roads can be difficult. Winter cyclists may use bikes with front and rear fenders, metal studded winter tires and flashing LED lights. Winter cyclists may wear layers of warm clothes and "ea face, and han coverings may be used. Specialized winter bikes called fatbikes, which have wide, oversized tires that are typically inflated with low pressure, are used in snow trail riding and winter bike competitions. Ter ...
