The rotary engine was an early type of internal combustion engine, usually designed with an odd number of cylinders per row in a radial configuration, in which the crankshaft remained stationary in operation, with the entire crankcase and its attached cylinders rotating around it as a unit. Its main application was in aviation, although it also saw use before its primary aviation role, in a few early motorcycles and automobiles.
A moped is a type of small motorcycle with bicycle pedals, generally having a less stringent licensing requirement than full motorcycles or automobiles. Mopeds typically travel only a bit faster than bicycles on public roads, and possess both a motorcycle engine and pedals for propulsion. Mopeds are distinguished from scooters in that the latter tend to be more powerful and subject to more regulation.
A flat-twin engine is a two-cylinder internal combustion engine with the cylinders on opposite sides of the crankshaft. The most common type of flat-twin engine is the boxer-twin engine, where both cylinders move inwards and outwards at the same time.
The Norton Motorcycle Company is an English motorcycle marque, originally from Birmingham, England, UK. It was founded in 1898 as a manufacturer of "fittings and parts for the two-wheel trade". By 1902 the company had begun manufacturing motorcycles with bought-in engines. In 1908 a Norton-built engine was added to the range. This began a long series of production of single and eventually twin-cylinder motorcycles, and a long history of racing involvement. During the Second World War Norton produced almost 100,000 of the military Model 16 H and Big 4 sidevalve motorcycles.
NSU Motorenwerke AG, or NSU, was a German manufacturer of automobiles, motorcycles and pedal cycles, founded in 1873. Acquired by Volkswagen Group in 1969, VW merged NSU with Auto Union, creating Audi NSU Auto Union AG, ultimately Audi. The name NSU originated as an abbreviation of "Neckarsulm", the city where NSU was located.
The Scott Motorcycle Company was owned by Scott Motors (Saltaire) Limited, Shipley, West Yorkshire, England and was a well-known producer of motorcycles and light engines for industry. Founded by Alfred Angas Scott in 1908 as the Scott Engineering Company in Bradford, Yorkshire, Scott motorcycles were produced until 1978.
The Swift Motor Company made Swift Cars in Coventry, England from 1900 until 1931. It grew progressively from James Starley's Coventry Sewing Machine Company, via bicycle and motorised cycle manufacture. The cars ranged from a single-cylinder car in 1900 using an MMC engine, through a Swift-engined twin-cylinder 7-horsepower light car in 1904, and a 3-litre model in 1913. After the First World War a successful range was sold during the 1920s, but the Cadet of 1930 was its last vehicle as it could not compete economically with volume manufacturers such as Ford and Morris Motors.
Phelon & Moore manufactured motorcycles in Cleckheaton, Yorkshire, England from 1904 to 1967 particularly those under the Panther marque. They became identified with one particular design of motorcycle which had a large sloping 40-degree single-cylinder engine as a stressed member of the frame. This design spanned the entire history of the company, starting with a 500 cc model and ending with a 645 cc model.
A motorcycle engine is an engine that powers a motorcycle. Motorcycle engines are typically two-stroke or four-stroke internal combustion engines, but other engine types, such as Wankels and electric motors, have been used.
A motorized bicycle is a bicycle with an attached motor or engine and transmission used either to power the vehicle unassisted, or to assist with pedalling. Since it always retains both pedals and a discrete connected drive for rider-powered propulsion, the motorised bicycle is in technical terms a true bicycle, albeit a power-assisted one. However, for purposes of governmental licensing and registration requirements, the type may be legally defined as a motor vehicle, motorbike, moped, or a separate class of hybrid vehicle.
Douglas was a British motorcycle manufacturer from 1907–1957 based in Kingswood, Bristol, owned by the Douglas family, and especially known for its horizontally opposed twin cylinder engined bikes and as manufacturers of speedway machines. The company also built a range of cars between 1913 and 1922.
The history of the motorcycle begins in the second half of the 19th century. Motorcycles are descended from the "safety bicycle," a bicycle with front and rear wheels of the same size and a pedal crank mechanism to drive the rear wheel. Despite some early landmarks in its development, the motorcycle lacks a rigid pedigree that can be traced back to a single idea or machine. Instead, the idea seems to have occurred to numerous engineers and inventors around Europe at around the same time.
The St John's Short Course was a road-racing street circuit used for the Isle of Man TT held between 1907 and 1910.
The FS1 was a Yamaha moped of the 1970s. Various letter suffixes were added to indicate model variation to suit local regulations, such the FS1-E for England, FS1P/DX NL and others.
Charles Benjamin Redrup (1878–1961) was a British aeronautical engineer and inventor, who designed several innovative axial engines.
Alfred Angas Scott (1875-1923) was a British motorcycle designer, inventor and founder of the Scott Motorcycle Company. A prolific inventor, he took out over 50 patents between 1897 and 1920, mostly concerning two-stroke engines and road vehicles. Scott was a keen potholer and the second president of the Gritstone club. In July 1923 Scott travelled back to Bradford in his open Scott Sociable wearing wet potholing clothes and contracted pneumonia from which he died.
Philip Edward Irving MBE, CEng., FIMechE., MSAE., (1903–1992) was an Australian engineer and author, most famous for the Repco-Brabham Formula One and Vincent motorcycle engines. He also worked at Velocette motorcycles, twice, and drew the engine of the 1960 EMC 125cc racer.
Bradbury Motor Cycles was a British motorcycle manufacturer based in Oldham, England and established in 1902. Originally involved in the manufacture of machine tools, sewing machines and cycles, their first motorcycles were bicycles with clip-on Minerva engines. The Bradbury factory went on to develop and produce a range of single-cylinder motorcycle, V-twins and horizontally opposed twins. The 1912 Bradbury motorcycles were one of the earliest with variable gearing. Although the factory survived the First World War it closed in 1924.
Granville Eastwood Bradshaw OBE, AFRAeS (1887–1969) was an English engineer and inventor who designed motorcycle, auto, and aero-engines.
The FN Four was the world's first production inline-4 motorcycle, manufactured in Liége by Fabrique Nationale from 1905 until 1923. It was also, at 40 miles per hour (64 km/h), the world's fastest production motorcycle from 1911 until 1912.
