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 p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Recumbent Bicycle
A recumbent bicycle is a bicycle that places the rider in a laid-back reclining position, and often called a Human-powered_land_vehicle, human-powered vehicle or HPV, especially if it has an aerodynamic fairing. Recumbents are available in a wide range of configurations, including: long to short wheelbase; large, small, or a mix of wheel sizes; overseat, underseat, or no-hands steering; and rear wheel or front wheel drive. A variant with three wheels is a recumbent tricycle, with four wheels a quadracycle. Recumbents can be faster than upright bicycles, but they were banned by the Union Cycliste Internationale (UCI) in 1934. Recumbent races and records are now overseen by the World Human Powered Vehicle Association (WHPVA), International Human Powered Vehicle Association (IHPVA) and World Recumbent Racing Association (WRRA). Some recumbent riders may choose this type of design for ergonomic reasons: the rider's weight is distributed comfortably over a larger area, supported by ...

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 Bicycle handlebar#Ape hangers, ape hanger handlebars. A lot of chrome plating, chrome, velvet, and overspoked wheels are common accessories to these custom bicycles. The bikes are typically a highly individualized creation. Early modified bikes have been crafted as a part of Lowrider, lowrider culture by Chicano youth since the 1960s. They were at first stigmatized by mainstream U.S. culture, even as they were a symbol of pride in Chicano communities. They later became accepted and popular elsewhere. ''Lowrider (magazine), Lowrider Bicycle'' was a magazine dedicated to the bikes first published in 1993. The bikes are now popular internationally, such as in Japan and Europe. Despite the fact that these bikes originated within the poverty of the barrio, lowrider bikes can be expensive. Some of the ...

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 bicycle, single-speed drivetrain, and straightforward bicycle frame#Frame materials, 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. Since mounting or dismounting a step-through does not require swinging one leg to hip-height, they are widely used as delivery bicycles, and for other purposes where the rider has to mount and dismount frequently. Traditionally, bicycles with a step-through frame were known as "ladies, "women's" or "girls' bicycles", as they allow skirts or dresses to hang fairly normally. Bicycles with a high top tube (cross-bar), were known as "men's", "gents", or "boys' bicycles". Even in the 1800s, women often rode "men's" bicycles and vice-versa; from the 1890s onwards, women commonly wore bloomers to cycle. Since the late 20th century, descriptions that describe the frame style, rather than the presumed gender of the rider, are becoming increasingly common.

Dress
A dress (also known as a frock or a gown) is a one-piece outer garment that is worn on the torso, hangs down over the legs, and is primarily worn by women or girls. Dresses often consist of a bodice attached to a skirt. Dress shapes, silhouettes, textiles, and colors vary. In particular, dresses can vary by sleeve length, neckline, skirt length, or hemline. These variances may be based on considerations such as fashion trends, modesty, weather, and personal taste. Dresses are generally suitable for both formal wear and casual wear in the West. Historically, foundation garments and other structural garments—including items such as corsets, partlets, petticoats, panniers, and bustles—were used to achieve the desired silhouette. History Middle Ages In the 11th century, women in Europe wore loose garments that were similar in shape to the tunics worn by men. Sleeves varied in fit and length, and hemlines fell below the knees, most often reaching the ankle or gr ... [...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 England. The hemline of skirts can vary from micro to floor-length and can vary according to cultural conceptions of modesty and aesthetics as well as the wearer's personal tast ...

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 internally ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
