The Kangaroo dwarf bicycle was created in 1884 by Hillman, Herbert, and Cooper as a safer alternative to the ordinary bicycle. [1] It had a 36-inch front drive wheel that was geared up to be equivalent to a 60 inch ordinary bicycle with a pair of chain drives, one on each side of the wheel. [2] The Kangaroo was soon superseded by the Rover and other, more-modern safety bicycles.
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.
A unicycle is a vehicle that touches the ground with only one wheel. The most common variation has a frame with a saddle, and has a pedal-driven direct-drive. A two speed hub is commercially available for faster unicycling. Unicycling is practiced professionally in circuses, by street performers, in festivals, and as a hobby. Unicycles have also been used to create new sports such as unicycle hockey. In recent years, unicycles have also been used in mountain unicycling, an activity similar to mountain biking or trials.
A mountain bike (MTB) or mountain bicycle is a bicycle designed for off-road cycling. Mountain bikes share some similarities with other bicycles, but incorporate features designed to enhance durability and performance in rough terrain, which makes them heavier, more complex and less efficient on smooth surfaces. These typically include a suspension fork, large knobby tires, more durable wheels, more powerful brakes, straight, extra wide handlebars to improve balance and comfort over rough terrain, and wide-ratio gearing optimised for topography, application and a frame with a suspension mechanism for the rear wheel. Rear suspension is ubiquitous in heavier-duty bikes and now common even in lighter bikes. Dropper seat posts can be installed to allow the rider to quickly adjust the seat height.
A recumbent bicycle is a bicycle that places the rider in a laid-back reclining position. Some recumbent riders may 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 sitting bones, the feet, and the hands.
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 legs, and comfort, because the large wheel provided greater shock absorption.
A hub gear, internal-gear hub, internally geared hub or just gear hub is a gear ratio changing system commonly used on bicycles that is implemented with planetary or epicyclic gears. The gears and lubricants are sealed within the shell of the hub gear, in contrast with derailleur gears where the gears and mechanism are exposed to the elements. Changing the gear ratio was traditionally accomplished by a shift lever connected to the hub with a Bowden cable, and twist-grip style shifters have become common.
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.
James Starley was an English inventor and father of the bicycle industry. He was one of the most innovative and successful builders of bicycles and tricycles. His inventions include the differential gear and the perfection of the bicycle chain drive.
Roller chain or bush roller chain is the type of chain drive most commonly used for transmission of mechanical power on many kinds of domestic, industrial and agricultural machinery, including conveyors, wire- and tube-drawing machines, printing presses, cars, motorcycles, and bicycles. It consists of a series of short cylindrical rollers held together by side links. It is driven by a toothed wheel called a sprocket. It is a simple, reliable, and efficient means of power transmission.
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 safety bicycle is a type of bicycle that became very popular beginning in the late 1880s as an alternative to the penny-farthing 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.
Gear ratios of bicycles are relative measures of bicycle gearing giving an indication of the mechanical advantage of different gears, which combined with the wheel diameter determines how far the bicycle advances per pedal or crank revolution.
Bicycle gearing is the aspect of a bicycle drivetrain that determines the relation between the cadence, the rate at which the rider pedals, and the rate at which the drive wheel turns.
John Kemp Starley was an English inventor and industrialist who is widely considered the inventor of the modern bicycle, and also originator of the tradename Rover.
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.
Coventry Premier Limited owned a British car and cyclecar manufacturing business based in Coventry from 1912 to 1923. It changed its name from Premier Cycles to Coventry Premier Ltd in November 1914.
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.
Bicycle drivetrain systems are used to transmit power on bicycles, tricycles, quadracycles, unicycles, or other human-powered vehicles from the riders to the drive wheels. Most also include some type of a mechanism to convert speed and torque via gear ratios.
The American Star Bicycle was invented in 1880 by G. W. Pressey and manufactured by the H. B. Smith Machine Company in Smithville, Burlington County, New Jersey. It was characterized by a small wheel in front to avoid the problem of tipping forward inherent in other high wheelers. A Star bicycle was photographed being ridden down the steps in front of the United States Capitol in 1885 to demonstrate its longitudinal stability, and Star bicycles were used for the sport of bicycle polo in the mid-1880s. Pressey sued Smith in 1887 for royalties. The name "Star" was attributed to the double star arrangement of the spokes.
Chain drive was also used on some late front-drivers, such as the Kangaroo, to achieve a lower riding position.
In 1884, Hillman, Herber, and Cooper of Coventry introduced the dwarf Kangaroo.
