Utility Bicycle
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 short, moderately paced rides through relatively flat urban areas. It is a form of utility bicycle commonly seen around the world, built to facilitate everyday riding in normal clothes in a variety of weather conditions. It is therefore a bicycle designed for utility cycling, 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 Bicycle sharing system, public bike sharing scheme. Generally as they are more suitable for urban environments, they focus more on comfort and practicality instead of speed or efficiency. They normally have a slightly curved, roughly p ...

Newspaper
A newspaper is a Periodical literature, periodical publication containing written News, information about current events and is often typed in black ink with a white or gray background. Newspapers can cover a wide variety of fields such as politics, business, sports, art, and science. They often include materials such as opinion columns, weather forecasts, reviews of local services, Obituary, obituaries, birth notices, crosswords, editorial cartoons, comic strips, and advice columns.

Intermodal Passenger Transport
Intermodal passenger transport, also called mixed-mode commuting, involves using two or more mode of transport, modes of transportation in a journey. Mixed-mode commuting is often used to combine the strengths (and offset the weaknesses) of various transportation options. A major goal of modern intermodal passenger transport is to reduce automobile dependency, dependence on the automobile as the major mode of ground transportation and increase use of public transport. To assist the traveller, various intermodal journey planners such as Rome2rio and Google Transit have been devised to help travellers plan and schedule their journey. Mixed-mode commuting often centers on a form of rapid transit, such as regional rail, which has high speed but limited coverage, to which low-speed options (i.e. bus, tram, or bicycle) are appended at the beginning or end of the journey. Trains offer quick transit from a suburb into an urban area, where passengers can choose a way to complete the tri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moulton Bicycle
Moulton is an English bicycle manufacturer based in Bradford-on-Avon, Wiltshire. The company was founded in 1962 by Alex Moulton (1920–2012) who had designed the " Hydrolastic" and rubber cone suspension systems for the BMC Mini motorcar. Moulton bicycles are noted for unconventional frame design, small wheels, and front and rear suspension. A misconception about Moultons is that they fold in the manner of more recent designs by manufacturers such as Brompton, Bickerton or Dahon. This is not true, though the Moulton design paved the way for such designs and various Moultons over the years have been made in separable versions allowing relatively easy dismantling for transportation or storage. Thus although Moultons are often included in the folding bicycle category along with small-wheel folders, small-wheel bicycles would be a more technically correct term covering all such bicycles. Mass-appeal versions such as the Standard and Deluxe were complemented by Speed version ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motorised Bicycle
A motorized bicycle is a bicycle with an motor or engine and transmission used either to power the vehicle unassisted, or to assist with pedalling. Since it sometimes retains both pedals and a discrete connected drive for rider-powered propulsion, the motorized bicycle is in technical terms a true bicycle, albeit a power-assisted one. Typically they are incapable of speeds above ; however, in recent years larger motors have been built, allowing bikes to reach speeds of upwards of 113 km/h (70 mph). Powered by a variety of engine types and designs, the motorized bicycle formed the prototype for what would later become the motor driven cycle. Terminology The term motorized bicycle refers to just a bicycle combining pedal power and internal combustion engine power. However, the term could be used as an umbrella category to refer to bicycles using sources besides pedal power. Electric bicycles technically could be in the category of motorized bicycles but instead of using inter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Two-cycle
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes of the piston, one up and one down, in one revolution of the crankshaft in contrast to a four-stroke engine which requires four strokes of the piston in two crankshaft revolutions to complete a power cycle. During the stroke from bottom dead center to top dead center, the end of the exhaust/intake (or scavenging) is completed along with the compression of the mixture. The second stroke encompasses the combustion of the mixture, the expansion of the burnt mixture and, near bottom dead center, the beginning of the scavenging flows. Two-stroke engines often have a higher power-to-weight ratio than a four-stroke engine, since their power stroke occurs twice as often. Two-stroke engines can also have fewer moving parts, and thus be cheaper to manufacture and weigh less. In countries and regions with stringent emissions regulation, two-stroke engines have be ...

Bicycle Brake Systems
A bicycle brake reduces the speed of a bicycle or prevents the wheels from moving. The two main types are: #Rim brakes, rim brakes and #Disc brakes, disc brakes. Drum brakes are less common on bicycles. Most bicycle brake systems consist of three main components: a mechanism for the rider to apply the brakes, such as #Brake levers, brake levers or Bicycle pedal, pedals; a mechanism for transmitting that signal, such as Bowden cables, hydraulic hoses, #Rod-actuated brakes, rods, or the bicycle chain; and the brake mechanism itself, a #Rim brakes, caliper or #Drum brakes, drum, to press two or more surfaces together in order to convert, via friction, kinetic energy of the bike and rider into thermal energy to be Dissipation, dissipated. History Karl Drais included a pivoting brake shoe that could be pressed against the rear iron tyre of his 1817 . This was continued on the earliest bicycles with pedals, such as the Boneshaker (bicycle)#Boneshaker, boneshaker, which were fitted with ...

Asia
Asia ( , ) is the largest continent in the world by both land area and population. It covers an area of more than 44 million square kilometres, about 30% of Earth's total land area and 8% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilisations. Its 4.7 billion people constitute roughly 60% of the world's population. Asia shares the landmass of Eurasia with Europe, and of Afro-Eurasia with both Europe and Africa. In general terms, it is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a social constructionism, historical and cultural construct, as there is no clear physical and geographical separation between them. A commonly accepted division places Asia to the east of the Suez Canal separating it from Africa; and to the east of the Turkish straits, the Ural Mountains an ...

Developing Country
A developing country is a sovereign state with a less-developed industrial base and a lower Human Development Index (HDI) relative to developed countries. However, this definition is not universally agreed upon. There is also no clear agreement on which countries fit this category. The terms low-and middle-income country (LMIC) and newly emerging economy (NEE) are often used interchangeably but they refer only to the economy of the countries. The World Bank classifies the world's economies into four groups, based on gross national income per capita: high-, upper-middle-, lower-middle-, and low-income countries. Least developed countries, landlocked developing countries, and small island developing states are all sub-groupings of developing countries. Countries on the other end of the spectrum are usually referred to as high-income countries or developed countries. There are controversies over the terms' use, as some feel that it perpetuates an outdated concept of "us" and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roadster (bicycle)
A roadster bicycle is a type of utility bicycle once common worldwide, and still common in Asia, Africa, Latin America, and some parts of Europe. During the past few decades, traditionally styled roadster bicycles have regained popularity in the Western world, particularly as a lifestyle or fashion statement in an urban environment. Design and variants There were three basic variants of the roadster. Roadster Gents' roadster The classic gents' roadster, also known as the English roadster, has a lugged brazed steel diamond frame, rod-actuated brakes and of late, cable operated drum brake systems have been widely produced for the European market, upright North Road handlebars, a single gear ratio or three- or five-speed hub gears, a chaincase, steel mudguards, steel cranks, (ISO 635) wheels, Westwood rims, and often a Sturmey-Archer hub dynamo. Roadsters are built for durability above all else and no serious attempt is made to save weight in their design or constructio ...

Bicycle Boom
The bike boom or bicycle craze is any of several specific historic periods marked by increased bicycle enthusiasm, popularity, and sales. Prominent examples include 1819 and 1868, as well as the decades of the 1890s and 1970sthe latter especially in North Americaand the 2010s in the United Kingdom. 1819 The first period which may be called a bicycle craze actually refers to a precursor of the bicycle which was propelled by being pushed along with the feet as the rider straddled the contraption, and had no pedals. This machine was invented by Baron Karl von Drais in Germany, and was called variously a "draisine" (English) or "draisienne" (French) after his name, a "velocipede" from the Latin terms for "fast foot", a "hobby horse", or a "dandy horse", the last name being perhaps the most popular. Drais got a patent for his invention in 1818, and the craze swept Europe and the United States during the summer of 1819 while many manufacturers (notably Denis Johnson of London) ...
