Treadle Bicycle
A treadle bicycle is a bicycle powered by a treadle instead of the more common crank. Treadles were one of the mechanisms inventors tried in order to position the pedals away from the drive wheel hub before the development of the bicycle chain or instead of it. Treadles have also been used to drive tricycles and quadracycles. History Treadles were used before the advent of highwheelers on Thomas McCall's velocipede, on highwheelers themselves in an attempt to address safety issues, on alternative configurations of highwheelers, and on the first device called a safety bicycle by British engineer Henry J. Lawson in 1876. Some inventors even combined treadles and chains on the same bicycle.

Quadracycle
A quadracycle is a four-wheeled human-powered land vehicle. It is also referred to as a quadricycle, quadcycle, pedal car or four-wheeled bicycle amongst other terms. Quadracycles have been in use since 1853 and have grown into several families of vehicles for a variety of purposes, including tourist rentals, pedal taxis, private touring, mountain and industrial use. Nomenclature There is no consensus amongst manufacturers of four-wheeled, human-powered vehicles as to what this class of vehicles should be called, although ''quadracycle'' is the most commonly used term. Manufacturers who do refer to their products by class of vehicle call them: *Quadracycle - 11 manufacturers *Four-wheel bicycle - 7 manufacturers *Quadricycle - 5 manufacturers *Quadcycle - 3 manufacturers *Pedal car - 2 manufacturers *Quad - 2 manufacturers In addition there are single manufacturers who call them Go-kart, Car, Car-Bike, Ecological car, Human Powered Vehicle, Pedal Kart, Quadribent, Quattroc ...

Outline Of Cycling
:''This article is an outline about the activity of cycling. For an outline about bicycles themselves, see outline of bicycles.'' :The following ''outline'' is provided as an overview of, as well as a topical guide to cycling: Cycling, also called bicycling or biking, is the activity of using / riding bicycles, (at least partially) human-powered, wheeled vehicles (typically by foot pedalling), for purposes including transport, recreation, social interaction, exercise, sport, therapy, other purposes, or any combination thereof. Persons engaged in cycling are called cyclists, bikers, or sometimes bicyclists. They typically either dress for where they are going, or for the cycling, sometimes having another set of clothing with them, or arranged. Apart from regular two-wheeled bicycles, cycling also includes riding unicycles, tricycles, quadricycles, and other similar human-powered wheeled vehicles (HPVs).

Elliptical Trainer
An elliptical trainer or cross-trainer is a stationary exercise machine used to stair climb, walk, or run without causing excessive pressure to the joints, hence decreasing the risk of impact injuries. For this reason, people with some injuries can use an elliptical to stay fit, as the low impact affects them little. Elliptical trainers offer a non-impact cardiovascular workout that can vary from light to high intensity based on the speed of the exercise and the resistance preference set by the user. Elliptical trainers first entered the market in the 1990s, invented by Precor. Most elliptical trainers work the user's upper and lower body (although some models do not have moving upper body components). Though elliptical trainers are considered to be minimal-impact, they are an example of a weight-bearing form of exercise. They can be self-powered by user-generated motion or need to be plugged in for adjustment of motion and/or for supplying their electronic consoles and res ...

Safety Bicycle
A safety bicycle (or simply a safety) is a type of bicycle that became very popular beginning in the late 1880s as an alternative to the penny-farthing ("ordinary") and is now the most common type of bicycle. Early bicycles of this style were known as safety bicycles because they were noted for, and marketed as, being safer than the high wheelers they were replacing. Even though modern bicycles use a similar design, the term is rarely used today and is considered obsolete outside circles familiar with high wheelers. Definition The term 'safety bicycle' was used in the 1880s for any alternative to the penny-farthing. The front and rear wheel were not necessarily the same size. Later historians began to use the term in a more restricted way for the design that was a direct ancestor to most modern bicycles. "Diamond frame" is also sometimes used as a term for safety bicycles, even though this technically only refers to a certain type of safety bicycle. The retronym "upright bicycle ...

Thomas McCall (inventor)
Thomas McCall (1834–1904) was a Scotland, Scottish Wainwright (occupation), cartwright. Biography McCall was born in Penpont, he came to Kilmarnock at age 20, where he lived until his death (obituary 1904). He built, in 1869, two versions of a two-wheeled velocipede with levers and rods tossing a crank on the rear wheel (''English Mechanic'' 5/14/1869 and 6/11/1869). This was a reaction to the French velocipedes, of the mid-1860s, with their front-wheel pedal cranks. In fact, this rear-wheel idea occupied seven more inventors in that year (Lessing 1991). When in the 1880s a rich corn-trader named James Johnston started a campaign to attribute the "first true" bicycle to his uncle Kirkpatrick MacMillan and his native country of Dumfries in general, he attributed the McCall designs to MacMillan and dated them as of 1839. Skeptics allege that the reason McCall built a replica of his machines to be exhibited as MacMillan's at the 1896 Stanley Cycle Show, Stanley Show, at the b ...

Penny-farthing
The penny-farthing, also known as a high wheel, high wheeler or ordinary, is an early type of bicycle. It was popular in the 1870s and 1880s, with its large front wheel providing high speeds (owing to its travelling a large distance for every rotation of the legs) and comfort (the large wheel provides greater shock absorption). It became obsolete in the late 1880s with the development of modern bicycles, which provided similar speed amplification via chain-driven gear trains and comfort through pneumatic tires, and were marketed in comparison to penny-farthings as " safety bicycles" because of the reduced danger of falling and the reduced height to fall from. The name came from the British penny and farthing coins, the former being much larger than the latter, so that the side view resembles a larger penny (the front wheel) leading a smaller farthing (the rear wheel). Although the name "penny-farthing" is now the most common, it was probably not used until the machines were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tricycle
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 powe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bicycle Chain
A bicycle chain is a roller chain that transfers power from the pedals to the drive-wheel of a bicycle, thus propelling it. Most bicycle chains are made from plain carbon or alloy steel, but some are nickel-plated to prevent rust, or simply for aesthetics. History Obsolete chain designs previously used on bicycles included the block chain, the skip-link chain, and the Simpson lever chain. The first chains were of a simple, bushing-less design. These had inherent reliability problems and a bit more friction (and mechanical efficiency losses) than modern chains. With these limitations in mind, the Nevoigt brothers, of the German Diamant Bicycle Company, designed the roller chain in 1898, which uses bushings. More recently, the "bushingless roller chain" design has superseded the bushed chain. This design incorporates the bearing surface of the bushing into the inner side plate, with each plate creating half of the bushing. This reduces the number of parts needed to assemb ...
