Bicycle Frame
A bicycle frame is the main component of a bicycle, onto which wheels and other components are fitted. The modern and most common frame design for an upright bicycle is based on the safety bicycle, and consists of two triangles: a main triangle and a paired rear triangle. This is known as the ''diamond frame''. Frames are required to be strong, stiff and light, which they do by combining different materials and shapes. A frameset consists of the frame and fork of a bicycle and sometimes includes the headset and seat post. Frame builders will often produce the frame and fork together as a paired set. Variations Besides the ubiquitous diamond frame, many different frame types have been developed for the bicycle, several of which are still in common use today. Diamond In the diamond frame, the main "triangle" is not actually a triangle because it consists of four tubes: the head tube, top tube, down tube and seat tube. The rear triangle consists of the seat tube joined by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bicycle Frame Mtb Hardtail
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 moder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Headset (bicycle Part)
The headset is the set of components on a bicycle that provides a rotatable interface between the bicycle fork and the head tube of a bicycle frame. The tube through which the steerer of the fork passes is called the head tube. A typical headset consists of two cups that are pressed into the top and bottom of the headtube. Inside the two cups are bearing (mechanical), bearings which provide a low friction contact between the bearing cup and the steerer. Sizes Traditional bicycle head tubes and headsets are sized for a steerer tube (also known as the fork column). Many frame and fork manufacturers are now building their parts around a steerer tube with a diameter of 1â…› inch. The larger diameter of the head tube and headset gives added stiffness to the steering portion of the bicycle. Common sizes *1" or 1 inch (25.4 Millimetre, mm). This may have a fork crown (The base of the fork steerer tube) of a number of different dimensions. Milling may be necessary to ma ...

Recumbent Bicycle
A recumbent bicycle is a bicycle that places the rider in a laid-back reclining position. Most recumbent riders 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 Tuberosity of the ischium, sitting bones, the feet, and the hands. Most recumbent models also have an aerodynamics, aerodynamic advantage; the reclined, legs-forward position of the rider's body presents a smaller frontal profile. A recumbent holds the world speed record for a bicycle, and they were banned from racing under the Union Cycliste Internationale (UCI) in 1934, and now race under the banner of the World Human Powered Vehicle Association (WHPVA) and International Human Powered Vehicle Association (IHPVA). Recumbents are available in a wide range of configurations, including: long to short wheelbase; large, small, or a mix ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wheelie Bike
A wheelie bike, also called a dragster, muscle bike, high-riser, spyder bike or banana bike, is a type of stylized children's bicycle designed in the 1960s to resemble a chopper motorcycle and characterized by ape hanger handlebars, a banana seat with sissy bar, and small () wheels. Notable examples include the Schwinn Sting-Ray and Krate lines and the Raleigh Chopper line. Other notable manufacturers and retailers that offered models include AMF, CCM, Columbia, Huffy, Iverson, J. C. Penney, Malvern Star, Monark, Murray, Ross, Sears, and Vindec. In modern usage, "wheelie bike" can refer to a large-frame BMX bike. History In 1962 Peter Mole of John T Bill & Co contacted Huffy Corp about making a new bicycle called High Rise. The bikes had a long seat called a banana seat with strut and taller handlebars. Huffy hesitated for several months before agreeing to make the bike with the stipulation that if it was a flop Peter Mole would buy all the left over parts an ...

Lowrider Bicycle
A lowrider bicycle is a highly customized bicycle with styling inspired by lowrider cars. These bikes often feature a long, curved banana seat with a sissy bar and very tall upward-swept ape hanger handlebars. A lot of chrome, velvet, and overspoked wheels are common accessories to these custom bicycles. These bikes are typically a highly individualized creation. Despite the fact that these bikes originated within the poverty of the barrio, lowrider bikes can be expensive. Noted American bicycle mechanic, technical expert, and author Sheldon Brown wrote of lowrider bicycles, History Lowrider bikes first appeared in August 23, 1961 in California. Children would emulate the craft of lowrider cars with their bicycles as a canvas for creativity, usually starting with common muscle bikes. This allowed those who were too young to drive a car to have a custom vehicle. In 1963, Schwinn was the first company to launch a muscle bike, in the form of the Schwinn Sting-Ray. Lowri ...

Cruiser Bicycle
A cruiser bicycle, also known as a beach cruiser or (formerly) motobike, is a bicycle that usually combines balloon tires, an upright seating posture, a single-speed drivetrain, and straightforward steel construction with expressive styling. Cruisers are popular among casual bicyclists and vacationers because they are very stable and easy to ride, but their heavy weight and balloon tires tend to make them rather slow. Another common feature is their ability to be customized with accessories including fenders, lights and saddle bags. They are designed for use primarily on paved roads, low speeds/distances, and are included in the non-racing/non-touring class and heavyweight or middleweight styles of the road bicycle type. The bikes, noted for their durability and heavy weight, were the most popular bicycle in the United States from the early 1930s through the 1950s, and have enjoyed renewed popularity since the late 1990s.

Mixte
A step-through frame (also known as open frame, drop frame, or low-step frame) is a type of bicycle frame, often used for utility bicycles, with a low or absent top tube or cross-bar. Traditionally, bicycles with a step-through frame were known as "ladies, "women's", or "girls' bicycles" mainly due to their advantage to riders wearing skirts or dresses. Bicycles with a high top tube (cross-bar), known as a diamond frame, were known as "men's", "gents, or "boys' bicycles". As a result of changing clothing styles since the late 20th century, descriptions that describe the frame style, rather than the presumed gender of the rider, are becoming increasingly common. Advantages * less risk of stretching or ripping clothes when mounting the saddle * the rider can wear a skirt (also requires a skirt guard and possibly a chain guard) * very quick to mount and dismount, so is suitable for delivery bicycles, or any journey with many stops * suitable for elderly and others with restrict ...

Dress
A dress (also known as a frock or a gown) is a garment traditionally worn by women or girls consisting of a skirt with an attached bodice (or a matching bodice giving the effect of a one-piece Clothing, garment). It consists of a top piece that covers the torso and hangs down over the legs. A dress can be any one-piece garment containing a skirt of any length, and can be formal wear, formal or casual wear, casual. A dress can have sleeves, straps, or be held up with elastic around the chest, leaving the shoulders bare. Dresses also vary in color. The hemlines of dresses vary depending on modesty, weather, fashion or the personal taste of the wearer. Overview Dresses are outer garments made up of a bodice and a skirt and can be made in one or more pieces. Dresses are generally suitable for both formal wear and casual wear in the West for women and girls. Historically, dresses could also include other items of clothing such as corsets, kirtles, partlets, petticoats, smocks, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skirt
A skirt is the lower part of a dress or a separate outer garment that covers a person from the waist downwards. At its simplest, a skirt can be a draped garment made out of a single piece of fabric (such as pareos). However, most skirts are fitted to the body at the waist or hips and fuller below, with the fullness introduced by means of darts, gores, pleats, or panels. Modern skirts are usually made of light to mid-weight fabrics, such as denim, jersey, worsted, or poplin. Skirts of thin or clingy fabrics are often worn with slips to make the material of the skirt drape better and for modesty. In modern times, skirts are very commonly worn by women and girls. Some exceptions include the izaar, worn by many Muslim cultures, and the kilt, a traditional men's garment in Scotland, Ireland, and sometimes England. Fashion designers such as Jean Paul Gaultier, Vivienne Westwood, Kenzo and Marc Jacobs have also shown men's skirts. Transgressing social codes, Gaultier fr ...

Fork End
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 internall ...

Bottom Bracket
The bottom bracket on a bicycle connects the crankset (chainset) to the bicycle and allows the crankset to rotate freely. It contains a spindle to which the crankset attaches, and the bearings that allow the spindle and crankset to rotate. The chainrings and pedals attach to the cranks. Bottom bracket bearings fit inside the bottom bracket shell, which connects the seat tube, down tube and chain stays as part of the bicycle frame. The term "bracket" refers to the tube fittings that are used to hold frame tubes together in lugged steel frames which also form the shell that contains the spindle and bearings; the term is now used for all frames, bracketed or not. There is some disagreement as to whether the word ''axle'' or ''spindle'' should be used in particular contexts. The distinction is based on whether the unit is stationary, as in a hub, or rotates, as in a bottom bracket. American bicycle mechanic and author Sheldon Brown uses ''axle'' once and ''spindle'' four tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
