Prone Bike
A prone bicycle is a bicycle which places the rider in a prone position. The bottom bracket is located at the bicycle's rear; the rider lies either on a pad or in a hard-shell seat. The prone position of the rider's body can reduce aerodynamic drag and therefore increase the efficiency of the vehicle. It can also be more comfortable or ergonomic than other bicycles. The first prone bicycle was developed and marketed by the American company Darling in 1897, but most prone bicycles are do-it-yourself constructions. There are few series-production models. In May, 2012, Graeme Obree announced that the bike he was building for his attempt at setting the human-powered vehicle land speed record is a prone bike. The attempt was originally to take place in Britain and the current record speed is 82.8 mph. However, he competed in the 2013 World Human Powered Speed Championships in Battle Mountain, Nevada, where the current record was also set. He achieved a speed of 56.62 mph ...

Prone Bike At MSOE
Prone position () is a body position in which the person lies flat with the chest down and the back up. In anatomical terms of location, the dorsal side is up, and the ventral side is down. The supine position is the 180° contrast. Etymology The word ''prone'', meaning "naturally inclined to something, apt, liable," has been recorded in English since 1382; the meaning "lying face-down" was first recorded in 1578, but is also referred to as "lying down" or "going prone." ''Prone'' derives from the Latin ', meaning "bent forward, inclined to," from the adverbial form of the prefix ''pro-'' "forward." Both the original, literal, and the derived figurative sense were used in Latin, but the figurative is older in English. Anatomy In anatomy, the prone position is a position of the body lying face down. It is opposed to the supine position which is face up. Using the terms defined in the anatomical position, the ventral side is down, and the dorsal side is up. Concerning the ... [...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] |

Bottom Bracket
The bottom bracket on a bicycle connects the crankset (chainset) to the bicycle and allows the crankset to rotate freely. It contains a spindle to which the crankset attaches, and the bearings that allow the spindle and crankset to rotate.

Drag (physics)
In fluid dynamics, drag (sometimes called air resistance, a type of friction, or fluid resistance, another type of friction or fluid friction) is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This can exist between two fluid layers (or surfaces) or between a fluid and a solid surface. Unlike other resistive forces, such as dry friction, which are nearly independent of velocity, the drag force depends on velocity. Drag force is proportional to the velocity for low-speed flow and the squared velocity for high speed flow, where the distinction between low and high speed is measured by the Reynolds number. Even though the ultimate cause of drag is viscous friction, turbulent drag is independent of viscosity. Drag forces always tend to decrease fluid velocity relative to the solid object in the fluid's path. Examples Examples of drag include the component of the net aerodynamic or hydrodynamic force acting opposite to the di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graeme Obree
Graeme Obree (born 11 September 1965), nicknamed The Flying Scotsman, is a Scottish racing cyclist who twice broke the world hour record, in July 1993 and April 1994, and was the individual pursuit world champion in 1993 and 1995. He was known for his unusual riding positions and for the ''Old Faithful'' bicycle he built which included parts from a washing machine. He joined a professional team in France but was fired before his first race. He also competed in the men's individual pursuit at the 1996 Summer Olympics. Obree has created some radical innovations in bicycle design and cycling position but has had problems with the cycling authorities banning the riding positions his designs required. Obree has been very open about living with bipolar disorder and depression, and the fact that he has attempted suicide three times, using his experiences as a means of encouraging other sportspeople to talk about their own mental health. His life and exploits have been dramatised in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daily Record (Scotland)
The ''Daily Record'' is a national tabloid newspaper which is published online also based in Glasgow, Scotland. The newspaper is published Monday-Saturday while the website is updated on an hourly basis, seven days a week. The ''Record'''s sister title is the '' Sunday Mail''. The title has been headquartered in Glasgow for its entire history. It is owned by Reach plc and has a close kinship with the UK-wide ''Daily Mirror'' as a result. The ''Record'' covers UK news and sport with a Scottish focus. Its website boasts the largest readership of any publisher based in Scotland. The title was at the forefront of technological advances in publishing throughout the 20th century and became the first European daily newspaper to be produced in full colour. For much of the last fifty years, the ''Sun'' has been the largest selling newspaper in Scotland. As the ''Records print circulation has declined in line with other national papers, it has focused increasing attention on expanding i ...

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] |
