A bicycle, also called a pedal cycle, bike, push-bike or cycle, is a human-powered or motor-assisted, pedal-driven, single-track vehicle, with two wheels attached to a frame, one behind the other. A bicycle rider is called a cyclist, or bicyclist.
Rambler is an automobile brand name that was first used by the Thomas B. Jeffery Company between 1900 and 1914.
In mechanical or automotive engineering, a freewheel or overrunning clutch is a device in a transmission that disengages the driveshaft from the driven shaft when the driven shaft rotates faster than the driveshaft. An overdrive is sometimes mistakenly called a freewheel, but is otherwise unrelated.
A utility bicycle, city bicycle, urban bicycle, European city bike (ECB), Dutch bike, classic bike or simply city-bike is a bicycle designed for frequent very short, relatively slow rides through very flat urban areas. It is a form of utility bicycle commonly seen around the world, built to facilitate everyday short-distance riding in normal clothes in cold-to-mild weather conditions. It is therefore a bicycle designed for very short-range practical transportation, as opposed to those primarily for recreation and competition, such as touring bicycles, road bicycles, and mountain bicycles. Utility bicycles are the most common form globally, and comprise the vast majority found in the developing world. City bikes may be individually owned or operated as part of a public bike sharing scheme.
A single-speed bicycle is a type of bicycle with a single gear ratio. These bicycles are without derailleur gears, hub gearing or other methods for varying the gear ratio of the bicycle.
A drive shaft, driveshaft, driving shaft, tailshaft, propeller shaft, or Cardan shaft is a component for transmitting mechanical power, torque, and rotation, usually used to connect other components of a drivetrain that cannot be connected directly because of distance or the need to allow for relative movement between them.
Vehicles that have two wheels and require balancing by the rider date back to the early 19th century. The first means of transport making use of two wheels arranged consecutively, and thus the archetype of the bicycle, was the German draisine dating back to 1817. The term bicycle was coined in France in the 1860s, and the descriptive title "penny farthing", used to describe an "ordinary bicycle", is a 19th-century term.
A shaft-driven bicycle is a bicycle that uses a drive shaft instead of a chain to transmit power from the pedals to the wheel. Shaft drives were introduced in the 1880s, but were mostly supplanted by chain-driven bicycles due to the gear ranges possible with sprockets and derailleurs. Around the 2000s, due to advancements in internal gear technology, a small number of modern shaft-driven bicycles have been introduced.
Development of the automobile started in 1672 with the invention of the first steam-powered vehicle, which led to the creation of the first steam-powered automobile capable of human transportation, built by Nicolas-Joseph Cugnot in 1769. Inventors began to branch out at the start of the 19th century, creating the de Rivaz engine, one of the first internal combustion engines, and an early electric motor. Samuel Brown later tested the first industrially applied internal combustion engine in 1826. Only two of these were made.
The Thomas B. Jeffery Company was an American automobile manufacturer in Kenosha, Wisconsin, from 1902 until 1916. The company manufactured the Rambler and Jeffery brand motorcars. It was preceded by the Gormully & Jeffery Manufacturing Company, a bicycle manufacturer. It was the predecessor company to Nash Motors, and thus one of the predecessor companies of American Motors Corporation (AMC) and later Chrysler.
Thomas Buckland Jeffery was a British emigrant to the United States who co-founded the Gormully & Jeffery company which made the Rambler bicycle. He invented the "clincher" rim which was widely used to fit tires to bicycles and early automobiles, and in 1900 established the Thomas B. Jeffery Company to make automobiles, again using Rambler branding.
Pope Manufacturing Company was founded by Albert Augustus Pope around 1876 in Boston, Massachusetts, US and incorporated in Hartford, Connecticut in 1877. Manufacturing of bicycles began in 1878 in Hartford at the Weed Sewing Machine Company factory. Pope manufactured bicycles, motorcycles, and automobiles. From 1905 to 1913, Pope gradually consolidated manufacturing to the Westfield Mass plant. The main offices remained in Hartford. It ceased automobile production in 1915 and ceased motorcycle production in 1918. The company subsequently underwent a variety of changes in form, name and product lines through the intervening years. To this day, bicycles continue to be sold under the Columbia brand.
The Nash Rambler is a North American automobile that was produced by the Nash Motors division of Nash-Kelvinator Corporation from 1950 until 1954 in sedan, wagon, and fixed-profile convertible body styles.
Rambler was an American bicycle brand manufactured by the Gormully & Jeffery Manufacturing Company (G&J) in Chicago from 1878 to 1900 and subsequently by the American Bicycle Company.
A belt-driven bicycle is a chainless bicycle that uses a flexible belt, typically a synchronous toothed design, in order to transmit power from the pedals to the wheel.
American Bicycle Company (1899-1903) was an American bicycle company (Trust) led by Albert Augustus Pope. The company was formed to consolidate the manufacturers of bicycles and bicycle parts. In the 1890s the advancements in bicycle design led to unprecedented demand for the new Safety bicycles. The "American Bicycle Company" trust only lasted for three years.
Electra Bicycle Company, a subsidiary of Trek Bicycle Company since 2014, was founded in Leucadia, California, in 1993, by Benno Bänziger and Jeano Erforth. Electra offers a wide range of modern cruiser bicycles. Additionally Electra designed and sells comfort bicycles, and hybrid bicycles. Electra also sells a line of accessories, apparel, and bicycle parts.
The DW-link is a subset of the common four-bar system used widely in bicycle suspension. The four-bar system has been used on mountain bikes since the early days of suspension. Similar suspension systems to the DW-link have been used by Schwinn, Fisher and Karpiel. Currently a similar system is used by Giant and named "Maestro". DW-link gets its name from the designer and patent holder, mechanical engineer Dave Weagle. Currently the DW-link has been licensed to the following bicycle companies: PIVOT Cycles, Ibis, Independent Fabrication, Turner Suspension Bicycles, and Iron Horse Bicycles. The DW-link suspension design was used to win six Elite level UCI downhill World Championships from 2005 to 2007, the highest contested level of the sport. This winning streak made the dw-link the most successful linkage suspension platform in the history of the sport of downhill. Dave Weagle also developed the Split Pivot suspension and Delta System which are both used in cycling.
A scooter is a motorcycle with an underbone or step-through frame, a seat, a transmission that shifts without the operator having to operate a clutch lever, a platform for the rider's feet, and with a method of operation that emphasizes comfort and fuel economy. Elements of scooter design were present in some of the earliest motorcycles, and motor scooters have been made since at least 1914. More recently, scooters have evolved to include scooters exceeding 250cc classified as Maxi-scooters.
