Bicycle Mechanic
A bicycle mechanic or bike mechanic is a mechanic who can perform a wide range of repairs on bicycles. Bicycle mechanics can be employed in various types of stores, ranging from large department stores to small local bike shops; cycling teams, or bicycle manufacturers. Classification and wages The New York State Department of Labor describes bicycle repair as a "realistic" occupation, meaning an occupation that would be enjoyed by somebody who likes "practical, hands-on problems," dealing with "real-world materials like wood, tools, and machinery," and one that "does not involve a lot of paperwork or working closely with others." They classify it as a job that "usually requires a high school diploma and may require some vocational training or job-related course work. In some cases, an associate's or bachelor's degree could be needed. Employees in these occupations need anywhere from a few months to one year of working with experienced employees." They indicate an annual wage in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bike Mechanic At A Local Bike Shop
A bicycle, also called a pedal cycle, bike or cycle, is a human-powered or motor-powered assisted, pedal-driven, single-track vehicle, having two wheels attached to a frame, one behind the other. A is called a cyclist, or bicyclist. Bicycles were introduced in the 19th century in Europe. By the early 21st century, more than 1 billion were in existence. These numbers far exceed the number of cars, both in total and ranked by the number of individual models produced. They are the principal means of transportation in many regions. They also provide a popular form of recreation, and have been adapted for use as children's toys, general fitness, military and police applications, courier services, bicycle racing, and bicycle stunts. The basic shape and configuration of a typical upright or "safety bicycle", has changed little since the first chain-driven model was developed around 1885. However, many details have been improved, especially since the advent of modern ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Learning Enrichment Foundation
The Learning Enrichment Foundation (LEF) is a Toronto-based organization that provides multiple services with a focus on skills training and economic development. The foundation provides immigrant settlement, supports language training, career exploration, job search supports, youth programs, and mentorship along with a variety of other skills training. The foundation is an advocate of integrated employment programs and accessible child care. History In the late 1970s, York, Toronto, The Borough of York (now a municipality of Toronto) was going through a major economic downturn with closed factories, high unemployment and vacancies. This caused a decline in both incomes and tax revenue, deflating rent prices. As a result, the region became attractive to a wave of recent immigrants. However, without the tax revenue, the Borough was unable to provide adequate social, education, and employment services. In response to these circumstances, a group of community stakeholders formed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mechanics (trade)
Mechanics (from Ancient Greek: μηχανική, ''mēkhanikḗ'', "of machines") is the area of mathematics and physics concerned with the relationships between force, matter, and motion among physical objects. Forces applied to objects result in displacements, or changes of an object's position relative to its environment. Theoretical expositions of this branch of physics has its origins in Ancient Greece, for instance, in the writings of Aristotle and Archimedes (see History of classical mechanics and Timeline of classical mechanics). During the early modern period, scientists such as Galileo, Kepler, Huygens, and Newton laid the foundation for what is now known as classical mechanics. As a branch of classical physics, mechanics deals with bodies that are either at rest or are moving with velocities significantly less than the speed of light. It can also be defined as the physical science that deals with the motion of and forces on bodies not in the quantum realm. His ...

Wheelbuilding
Wheelbuilding is the process of assembling wire wheels (generally a bicycle wheel, but including wheelchairs, and some cars). The components of a wire wheel are the rim, spokes, nipples, and hub. Goals The wheelwright must ensure that the wheel is true in two ways: lateral (sideways wobble) and radial Radial is a geometric term of location which may refer to: Mathematics and Direction * Vector (geometric), a line * Radius, adjective form of * Radial distance, a directional coordinate in a polar coordinate system * Radial set * A bearing f ... (roundness/hop). The wheel also needs to be properly dished if applicable (the left and right sides of the rear wheel differ, the drive-side spokes requiring higher tension). Spokes should have no residual twist (windup) from tightening the nipples. The spokes may be "stress relieved", i.e. subjected to a greater tension during building than they are ever likely to encounter in use - usually by squeezing pairs of spokes together ...

Spoke Wrench
A spoke wrench or spoke key is a small wrench or tool used to adjust the tension in the spokes of a tension-spoked wheel. A spoke wrench is sometimes called a nipple wrench, as it is the spoke nipple – not the spoke – that is turned in the process of changing the tension of a spoke. Overview Spoke nipples are typically T-shaped in cross section, with an internal thread running part of the way through the hole that runs along the spoke nipple's principal axis. A spoke nipple rests in a hole drilled radially through the wheel's rim, and the nipple is threaded onto the external thread of a spoke. The spoke itself is fixed, at its other end, through a hole in the hub. The spoke and nipple are functionally equivalent to a bolt and a nut. However, unlike a typical nut-and-bolt pair, a spoke and nipple do not join two parts (the rim and the hub) so much as bridge them, under tension. The area of the nipple around which the spoke wrench, or key, is fitted is generally square in cross-s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mechanic
A mechanic is an artisan, skilled tradesperson, or technician who uses tools to build, maintain, or repair machinery, especially cars. Duties Most mechanics specialize in a particular field, such as auto body mechanics, air conditioning and refrigeration mechanics, auto mechanics, bicycle mechanics, boiler mechanics, and other areas. A mechanic is typically certified by a trade association or regional government power. Mechanics may be separated into two classes based on the type of machines they work on, heavyweight and lightweight. Heavyweight work is on larger machines or heavy equipment, such as tractors and trailers, while lightweight work is on smaller items, such as automotive engines. Automotive mechanics/automotive technicians Automotive technicians (the modern term of reference) have many trades within. Some may specialize in the electrical diagnosis, while others may specialize in the mechanical aspects. Other mechanical areas include: brakes and steering, sus ...

Local Bike Shop
A local bike shop or local bicycle shop, sometimes abbreviated LBS, is a small business, as distinct from a chain, mail-order or online vendor, specializing in bicycle sale, maintenance and parts. In the UK and Ireland, the expression ''independent bicycle dealers'' (IBDs) is also used. The local bike shop is a key component of the bicycle industry and, in recognition of the value that local bike shops provide, some manufacturers only sell their bicycles through dealerships. Offerings Beyond bicycles, a local bicycle shop may offer clothing and other accessories, spare and replacement parts, tools, and a variety of services. Services may include expert fitting and custom bike building or ordering, maintenance and repairs from experienced bicycle mechanics, and organized group rides and classes. A self-service work area may be available. Shops may also specialize on one or more aspects of cycling: bicycle racing, triathlon, bicycle touring, BMX, mountain biking, etc ...

Derailleur Hanger
A fork end, fork-end, or forkend is a slot in a bicycle frame or bicycle fork where the axle of a bicycle wheel is attached. A dropout is a type of fork end that allows the rear wheel to be removed without first derailing the chain. Track bicycle frames have track fork ends, on which the opening faces rearwards. Because they do not have dropouts, the chain must be derailed from the sprocket before the rear wheel can be removed from a typical track bike. Some single-speed bicycles intended for street or trail use are also equipped with track fork ends instead of dropouts. On bicycles that do not have a derailleur or other chain tensioning device, rear ''horizontal dropouts'' allow adjustment of chain tension, and can accommodate a range of chain lengths or cog sizes. They were standard on most older derailleur bicycles from before the 1990s. An older derailleur-equipped bicycle with horizontal dropouts can be readily converted into singlespeed, fixed gear or to use an internally ...

Derailleur Gears
Shimano 600 front derailleur (1980) A derailleur is a variable-ratio bicycle gearing system consisting of a chain, multiple sprockets of different sizes, and a mechanism to move the chain from one sprocket to another. Modern front and rear derailleurs typically consist of a moveable chain-guide that is operated remotely by a Bowden cable attached to a shifter mounted on the down tube, handlebar stem, or handlebar. When a rider operates the lever while pedalling, the change in cable tension moves the chain-guide from side to side, "derailing" the chain onto different sprockets. Etymology ''Dérailleur'' is a French word, derived from the derailment of a train from its tracks. Its first recorded use was 1930. History A modern road bicycle drivetrain with front and rear derailleurs Various derailleur systems were designed and built in the late 19th century. One example is the Protean two-speed derailleur available on the Whippet safety bicycle. The French bicycle to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bicycle Tools
Various bicycle tools have evolved over the years into specialized tools for working on a bicycle. Modern bicycle shops will stock a large number of tools for working on different bicycle parts. This work can be performed by a trained bicycle mechanic, or for simple tasks, by the bicycle owner. Various tools by function Hub, wheel and tire tools *'' Tire levers'' are used for removing the tires from the rim, often for changing the inner tube. Plastic levers are more prone to breakage; metal ones damage tubes, tires, or rims more easily. *'' Cone wrenches (spanners)'' are needed to dismantle and adjust the hub bearings. *''Spoke wrenches'' are used for tensioning the spokes of a wheel. *''Tensiometer'' or ''spoke tension meter'' is used to measure the tension in spokes. *''Tire bead jack'' can be used to install tires on rims, especially when the tire-rim combination is tight. *''Dishing gauge'' is used to measure the dish of a wheel. *'' Wheel truing stand'' is used to measur ...
