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 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 (also known as an "ordinary" or "high wheeler") and is now the most common type of bicycle.

Quadracycle
A quadracycle (also spelled quadricycle) is a four-wheeled human-powered land vehicle. It is also referred to as a 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, Quadri ...

Outline Of Cycling
Cycling, also known as bicycling or biking, is the activity of riding bicycles or other Human-powered transport, human-powered vehicles with Wheel, wheels, for transportation, recreation, exercise, sport, and other purposes. People who engage in cycling are called cyclists, bikers, or bicyclists. They may wear everyday clothing suited to their destination or specialized cycling attire, sometimes carrying an additional set of clothes. Cycling includes not only traditional two-wheeled bicycles but also unicycles, tricycles, quadricycles, and other human-powered transport, human-powered vehicles (HPVs). Some bicycles are equipped with Electric motor, electric motors (e-bikes) or other forms of Motorized bicycle, motor assistance. Cycling can be done individually or with others. Passengers may ride in front,for instance in the box of a cargo bike, sit on a luggage carrier, or use specially designed seats for children or pets.

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 resi ...

ElliptiGO
ElliptiGO, Inc. is a manufacturer of stand-up and elliptical bicycles headquartered in Solana Beach, California. Elliptical bikes combine the motion of an indoor elliptical trainer with the outdoor mobility of a traditional bicycle. They are a type of treadle bicycle, powered by treadles (which are attached to the crank via a linkage rod), rather than pedals mounted directly on the crank arms. Treadle drive trains were historically intermediate between highwheeled penny-farthings (which were powered by pedals mounted directly on a crank through the wheel hub, like a modern child's tricycle) and the bicycle chain A bicycle chain is a roller chain that transfers power (physics), power from the Bicycle pedal, pedals to the Drive wheel, drive-Bicycle wheel, wheel of a bicycle, thus propelling it. Most bicycle chains are made from carbon steel, plain carbo ...; Elliptigos, like some other later treadle bicycles, use both treadles and a chain. History Co-founders Bryan Pate an ...

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 (also known as an "ordinary" or "high wheeler") 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 bic ...

Thomas McCall (inventor)
Thomas McCall (1834–1904) was a Scottish 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 Show, at the behest of Johnston, can only be a need of money (Cla ...

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 it travelling a large distance for every rotation of the wheel. These bicycles had solid Natural rubber, rubber tires and as a consequence the only Shock absorber, shock absorption was in the saddle. The penny-farthing became obsolete in the late 1880s with the development of modern bicycles, which provided similar speed, via a chain drive, chain-driven gear train, and comfort, from the use of pneumatic tires. These later bikes were marketed as "safety bicycles" because of the greater ease of mounting and dismounting, the reduced danger of falling, and the reduced height to fall, in comparison to penny-farthings. The name came from the British penny (British pre-decimal coin), penny and farthing (British coin), farthing coins, the penny being much larger than the farthing, so that ...

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] |

Bicycle Chain
A bicycle chain is a roller chain that transfers power (physics), power from the Bicycle pedal, pedals to the Drive wheel, drive-Bicycle wheel, wheel of a bicycle, thus propelling it. Most bicycle chains are made from carbon steel, plain carbon or alloy steel, but some are nickel electroplating, nickel-plated to prevent rust, or simply for aesthetics. History Obsolete chain designs previously used on bicycles included the bar-link chain, 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 (German bicycle company), 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 surfac ...
