Road cycling is the most widespread form of cycling in which cyclists ride on paved roadways. It includes recreational , racing , commuting , and utility cycling . As users of the road, road cyclists are generally expected to obey the same laws as motorists, however there are certain exceptions. While there are many types of bicycles that are used on the roads such as BMX , recumbents , racing , touring and utility bicycles , dedicated road bicycles have specific characteristics that make them ideal for the sport. Road bicycles generally have thinner tires, lighter frames with no suspension, and a set of drop handle bars to allow riders to get in a more aerodynamic position while cycling at higher speeds. On a flat road, an intermediate cyclist can average about 18 to 20 mph (29 to 32 km/h), while a professional rider can average up to 25 mph (40 km/h). At higher speeds, wind resistance becomes an important factor; aerodynamic road bikes have been developed over the years to ensure that as much as possible of the rider's energy is spent propelling the bike forward.
59-412: In 1817, Karl von Drais created the first bicycle which used heavy steel and wood , but since then, the road bicycle industry has adopted aluminum , carbon fiber , and titanium as the main materials for production. The first steel bicycles weighed as much as 80 pounds, whereas the lightest carbon fiber road bikes now can weigh as little as thirteen pounds. On May 31, 1868, cycling officially became

The typebars of "normal" characters struck a rod as they moved the metal character desired toward the ribbon and platen, and each rod depression moved the platen forward the width of one character. Dead keys had a typebar shaped so as not to strike the rod. In English-speaking countries, ordinary typewriters printing fixed-width characters were standardized to print six horizontal lines per vertical inch, and had either of two variants of character width, one called pica for ten characters per horizontal inch and

On 29 April 2010, Google celebrated 225th Birthday of Karl Drais with a doodle. In 2017, Germany issued a commemorative postage stamp (0.70 Euro) in remembrance of the 200th anniversary of Karl Drais's first run of his "running machine" on 12 June 1817. The stamp shows

Then, in 1875, the well-known "tall model" was patented, which was the first of the writing balls that worked without electricity. Malling-Hansen attended the world exhibitions in Vienna in 1873 and Paris in 1878 and he received the first-prize for his invention at both exhibitions. The first typewriter to be commercially successful
295-421: A firm contract for the next batch. However, Remington was engaged in merger talks, which would eventually result in the creation of Remington Rand and no executives were willing to commit to a firm order. Northeast instead decided to enter the typewriter business for itself, and in 1929 produced the first Electromatic Typewriter. In 1928, Delco , a division of General Motors , purchased Northeast Electric, and
354-427: A land surveyor on the fazenda of Georg Heinrich von Langsdorff . In 1827, he returned to Mannheim . Three years later in 1830, Drais's father died and the younger Drais was mobbed by jealous rivals. In 1839, after surviving a murderous attack in 1838, he moved to the village of Waldkatzenbach in the hills of Odenwald and remained there until 1845. During this period, he invented the railway handcar (later known as
413-527: A manufacturer of sewing machines ) to commercialize the machine as the Sholes and Glidden Type-Writer . This was the origin of the term typewriter . Remington began production of its first typewriter on March 1, 1873, in Ilion, New York . It had a QWERTY keyboard layout, which, because of the machine's success, was slowly adopted by other typewriter manufacturers. As with most other early typewriters, because
472-551: A result, on 12 January 1818, Drais was awarded a grand-ducal privilege ( Großherzogliches Privileg ) to protect his inventions for 10 years in Baden by the younger Grand Duke Karl . Grand Duke Karl also appointed Drais professor of mechanics . This was merely an honorary title, not related to any university or other institution. Drais retired from the civil service and was awarded a pension for his appointment to professor of mechanical science. In 1820, trouble overtook Drais when
531-500: A sport with the first race occurring at Saint-Cloud Park in France . While this first race was not considered a road race, road cycling races began to pop up throughout Europe in the 1870s. Road cycling as a form of recreational activity as well as a way to commute began to gain traction shortly after these first road races. Since its origins, millions of people have adopted road cycling for either recreation or commuting. In 2020, it
590-457: A standard fixture in most offices up to the 1980s. After that, they began to be largely supplanted by personal computers running word processing software. Nevertheless, typewriters remain common in some parts of the world. For example, typewriters are still used in many Indian cities and towns, especially in roadside and legal offices, due to a lack of continuous, reliable electricity. The QWERTY keyboard layout , developed for typewriters in
649-650: A workable design. Some early typing instruments include: By the mid-19th century, the increasing pace of business communication had created a need to mechanize the writing process. Stenographers and telegraphers could take down information at rates up to 130 words per minute, whereas a writer with a pen was limited to a maximum of 30 words per minute (the 1853 speed record). From 1829 to 1870, many printing or typing machines were patented by inventors in Europe and America, but none went into commercial production. In 1865, Rev. Rasmus Malling-Hansen of Denmark invented

In 1920, after returning from Army service, he produced a successful model and in 1923 turned it over to the Northeast Electric Company of Rochester for development. Northeast was interested in finding new markets for their electric motors and developed Smathers's design so that it could be marketed to typewriter manufacturers, and from 1925 Remington Electric typewriters were produced powered by Northeast's motors. After some 2,500 electric typewriters had been produced, Northeast asked Remington for
767-569: The Hansen Writing Ball , which went into commercial production in 1870 and was the first commercially sold typewriter. It was a success in Europe and was reported as being used in offices on the European continent as late as 1909. Malling-Hansen used a solenoid escapement to return the carriage on some of his models, which makes him a candidate for the title of inventor of the first "electric" typewriter. The Hansen Writing Ball

Subsequently, after the revolution collapsed, he was in a very bad position. The royalists tried to have him certified as mad and locked up. His pension was confiscated to help to pay for the "costs of revolution" after it
885-531: The font . In 1941, IBM announced the Electromatic Model 04 electric typewriter, featuring the revolutionary concept of proportional spacing. By assigning varied rather than uniform spacing to different sized characters, the Type 4 recreated the appearance of a typeset page, an effect that was further enhanced by including the 1937 innovation of carbon-film ribbons that produced clearer, sharper words on
944-441: The 1870s, remains the de facto standard for English-language computer keyboards . The origins of this layout still need to be clarified. Similar typewriter keyboards, with layouts optimised for other languages and orthographies, emerged soon afterward, and their layouts have also become standard for computer keyboards in their respective markets. Although many modern typewriters have one of several similar designs, their invention
1003-590: The Bar-Let and the Corona No. 3 Typewriter have two separate shift keys, a "CAP" shift (for uppercase) and a "FIG" shift (for numbers and symbols). The Murray code was developed for a teletypewriter with a similar three-row typewriter keyboard. To facilitate typewriter use in business settings, a tab (tabulator) key was added in the late nineteenth century. Before using the key, the operator had to set mechanical "tab stops", pre-designated locations to which
1062-551: The Simplex Typewriter Company made index typewriters for 1/40 the price of a Remington typewriter. The index typewriter's niche appeal however soon disappeared as, on the one hand new keyboard typewriters became lighter and more portable, and on the other refurbished second-hand machines began to become available. The last widely available western index machine was the Mignon typewriter produced by AEG which
1121-521: The United States, and even Calcutta banned its use, which ended its vogue for decades. Drais also invented the earliest typewriter with a keyboard (1821). He later developed an early stenograph machine which used 16 characters (1827), a device to record piano music on paper (1812), the first meat grinder (1840s), and a wood-saving cooker including the earliest hay chest . He also invented two four-wheeled human powered vehicles (1813/1814),
1180-461: The United States—but before the advent of daisywheel and electronic machines—the typewriter market faced strong competition from less expensive typewriters from Asia, including Brother Industries and Silver Seiko Ltd. of Japan. In most of the early typewriters, the typebars struck upward against the paper, pressed against the bottom of the platen , so the typist could not see the text as it
1239-417: The basket of typebars, in which case the typewriter is described as "basket shift", or the paper-holding carriage, in which case the typewriter is described as "carriage shift". Either mechanism caused a different portion of the typebar to come in contact with the ribbon/platen. The result is that each typebar could type two different characters, cutting the number of keys and typebars in half (and simplifying
SECTION 20
#17327870036041298-429: The carriage would advance when the tab key was pressed. This facilitated the typing of columns of numbers, freeing the operator from the need to manually position the carriage. The first models had one tab stop and one tab key; later ones allowed as many stops as desired, and sometimes had multiple tab keys, each of which moved the carriage a different number of spaces ahead of the decimal point (the tab stop), to facilitate
1357-409: The concept that each key was attached to a typebar that had the corresponding letter molded, in reverse, into its striking head. When a key was struck briskly and firmly, the typebar hit a ribbon (usually made of inked fabric ), making a printed mark on the paper wrapped around a cylindrical platen . The platen was mounted on a carriage that moved horizontally to the left, automatically advancing
1416-516: The electric typewriter came in 1910, when Charles and Howard Krum filed a patent for the first practical teletypewriter . The Krums' machine, named the Morkrum Printing Telegraph, used a typewheel rather than individual typebars. This machine was used for the first commercial teletypewriter system on Postal Telegraph Company lines between Boston and New York City in 1910. James Fields Smathers of Kansas City invented what
1475-568: The electric typewriter was laid by the Universal Stock Ticker , invented by Thomas Edison in 1870. This device remotely printed letters and numbers on a stream of paper tape from input generated by a specially designed typewriter at the other end of a telegraph line. Some electric typewriters were patented in the 19th century, but the first machine known to be produced in series is the Cahill of 1900. Another electric typewriter
1534-611: The end of the 19th century, a person who used such a device was also referred to as a type writer . The first commercial typewriters were introduced in 1874, but did not become common in offices in the United States until after the mid-1880s. The typewriter quickly became an indispensable tool for practically all writing other than personal handwritten correspondence. It was widely used by professional writers, in offices, in business correspondence in private homes, and by students preparing written assignments. Typewriters were
1593-502: The event of an accident. In 2019, 846 cyclists were killed in road related accidents in the United States. Most fatal bike crashes were caused between 6 P.M. and 9 P.M. and about 78% of fatal crashes in 2019 were in urban areas. Some tips for crash prevention are: Some of the major companies within the road cycling industry are: Karl Drais Karl Freiherr von Drais (full name: Karl Friedrich Christian Ludwig Freiherr Drais von Sauerbronn ; 29 April 1785 – 10 December 1851)
1652-508: The far left was then pressed to the right to return the carriage to its starting position and rotating the platen to advance the paper vertically. A small bell was struck a few characters before the right hand margin was reached to warn the operator to complete the word and then use the carriage-return lever. By about 1910, the "manual" or "mechanical" typewriter had reached a somewhat standardized design. There were minor variations from one manufacturer to another, but most typewriters followed
1711-602: The front side of the platen, became standard. One of the first was the Daugherty Visible, introduced in 1893, which also introduced the four-bank keyboard that became standard, although the Underwood which came out two years later was the first major typewriter with these features. A significant innovation was the shift key , introduced with the Remington No. 2 in 1878. This key physically "shifted" either

Embossing tape label makers are the most common index typewriters today, and perhaps the most common typewriters of any kind still being manufactured. The platen was mounted on a carriage that moved horizontally to the left, automatically advancing the typing position, after each character was typed. The carriage-return lever at

The obvious use for this was to allow letter keys to type both upper and lower case , but normally the number keys were also duplexed, allowing access to special symbols such as percent, % , and ampersand, & . Before the shift key, typewriters had to have a separate key and typebar for upper-case letters; in essence, the typewriter had two keyboards, one above

1888-496: The keyboard. In the early part of the 20th century, a typewriter was marketed under the name Noiseless and advertised as "silent". It was developed by Wellington Parker Kidder and the first model was marketed by the Noiseless Typewriter Company in 1917. Noiseless portables sold well in the 1930s and 1940s, and noiseless standards continued to be manufactured until the 1960s. In a conventional typewriter
1947-452: The machine plus as its shadow, a bicycle. Typewriter A typewriter is a mechanical or electromechanical machine for typing characters. Typically, a typewriter has an array of keys , and each one causes a different single character to be produced on paper by striking an inked ribbon selectively against the paper with a type element . Thereby, the machine produces a legible written document composed of ink and paper. By
2006-414: The number of whose characters (sorts) was constrained by the physical limits of the machine, the number of keys required was reduced by the use of dead keys . Diacritics such as ´ ( acute accent ) would be assigned to a dead key , which did not move the platen forward, permitting another character to be imprinted at the same location; thus a single dead key such as the acute accent could be combined with

This differed from the use of these terms in printing, where pica is a linear unit (approximately 1 ⁄ 6 of an inch) used for any measurement, the most common one being the height of a typeface. Some ribbons were inked in black and red stripes, each being half the width and running the entire length of the ribbon. A lever on most machines allowed switching between colors, which
2183-684: The other. With the shift key, manufacturing costs (and therefore purchase price) were greatly reduced, and typist operation was simplified; both factors contributed greatly to mass adoption of the technology. Certain models further reduced the number of keys and typebars by making each key perform three functions – each typebar could type three different characters. These little three-row machines were portable and could be used by journalists. Such three-row machines were popular with WWI journalists because they were lighter and more compact than four-bank typewriters, while they could type just as fast and use just as many symbols. Such three-row machines, such as

In 1822, Drais was a fervent liberal who supported revolution in Baden . Drais's conservative father, as the highest Judge of Baden , had not entered a plea for pardon in the beheading of Karl Ludwig Sand , and the younger Drais was mobbed by the student partisans everywhere in Germany due to his family ties. Therefore, Drais emigrated to Brazil where he lived from 1822 to 1827, and worked as

The first typewriter to have the sliding type bars (laid out horizontally like a fan) that enable a typewriter to be "noiseless" was the American made Rapid which appeared briefly on the market in 1890. The Rapid also had the remarkable ability for

2478-403: The type bar reaches the end of its travel simply by striking the ribbon and paper. The Noiseless, developed by Kidder, has a complex lever mechanism that decelerates the type bar mechanically before pressing it against the ribbon and paper in an attempt to dampen the noise. Although electric typewriters would not achieve widespread popularity until nearly a century later, the basic groundwork for
2537-762: The typebars strike upwards, the typist could not see the characters as they were typed. The index typewriter came into the market in the early 1880s. The index typewriter uses a pointer or stylus to choose a letter from an index. The pointer is mechanically linked so that the letter chosen could then be printed, most often by the activation of a lever. The index typewriter was briefly popular in niche markets. Although they were slower than keyboard type machines, they were mechanically simpler and lighter. They were therefore marketed as being suitable for travellers and, because they could be produced more cheaply than keyboard machines, as budget machines for users who needed to produce small quantities of typed correspondence. For example,
2596-632: The typewriter business was spun off as Electromatic Typewriters, Inc. In 1933, Electromatic was acquired by IBM , which then spent $ 1 million on a redesign of the Electromatic Typewriter, launching the IBM Electric Typewriter Model 01. In 1931, an electric typewriter was introduced by Varityper Corporation. It was called the Varityper , because a narrow cylinder-like wheel could be replaced to change
2655-444: The typing of columns with numbers of different length ($ 1.00, $ 10.00, $ 100.00, etc.) Languages such as French, Spanish, and German required diacritics , special signs attached to or on top of the base letter: for example, a combination of the acute accent ´ plus e produced é ; ~ plus n produced ñ . In metal typesetting , ⟨é⟩ , ⟨ñ⟩ , and others were separate sorts . With mechanical typewriters,
2714-455: The typing position, after each character was typed. The carriage-return lever at the far left was then pressed to the right to return the carriage to its starting position and rotating the platen to advance the paper vertically. A small bell was struck a few characters before the right hand margin was reached to warn the operator to complete the word and then use the carriage-return lever. Typewriters for languages written right-to-left operate in

The two keys that achieve this are positioned at the top of the keyboard (seen in the detail image below). They are a "Lift" key that advances the paper, on the platen, to the next line and a "Return" key that causes the carriage to automatically swing back to the right, ready for one to type the new line. So an entire page could be typed without one's hands leaving

Demand for road bicycles as well as other types of bicycles continued to increase throughout 2021. Sharing the roadways with other motorists is an unavoidable aspect of road cycling, so road cyclists are generally expected to follow the same laws as their motorist counterparts. That being said, road cyclists also have

It incorporated the two-wheeler principle that is basic to the bicycle and motorcycle and was the beginning of mechanized personal transport. This was the earliest form of a bicycle, without pedals. His first reported ride from Mannheim to the "Schwetzinger Relaishaus" (a coaching inn , located in "Rheinau", today a district of Mannheim) took place on 12 June 1817 using Baden's best road.

Malling-Hansen developed his typewriter further through the 1870s and 1880s and made many improvements, but the writing head remained the same. On the first model of the writing ball from 1870, the paper was attached to
