Skirt Guard
A skirt guard, dress guard or coat guard is a device fitted over the rear wheel of a bicycle to prevent a long skirt, coat or other trailing clothes or luggage catching in the wheel, or in the gap between the rim and the brakes. These guards also help prevent a child's foot becoming entangled in the spokes, when they are seated on a rear child seat or directly on a rear rack. Skirt guards are common on bicycles in continental Europe, where the bicycle is commonly ridden in smart-casual or formal clothing; but very uncommon in English-speaking countries where many cyclists wear specialised cycling gear. It is often paired with a chain guard to keep the rider's clothing clean. They are often used on 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.

Citibike 00001 Jeh
Citi Bike is a privately owned public bicycle sharing system serving the New York City boroughs of the Bronx, Brooklyn, Manhattan, and Queens, as well as Jersey City and Hoboken, New Jersey. Named after lead sponsor Citigroup, it was operated by Motivate (formerly Alta Bicycle Share), with former Metropolitan Transportation Authority CEO Jay Walder as chief executive until September 30, 2018, when the company was acquired by Lyft. The system's bikes and stations use technology from Lyft. First proposed in 2008 by the New York City Department of Transportation, Citi Bike's scheduled 2011 opening was delayed by Hurricane Sandy and technological problems. It officially opened in May 2013 with 332 stations and 6,000 bikes. By October 2017 annual expansions brought the totals to 706 stations and 12,000 bikes, making the service the largest bike sharing program in the United States. Further expansions for Citi Bike are planned to extend its service area across the Bronx, Brooklyn, M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bicycle
A bicycle, also called a pedal cycle, bike, push-bike or cycle, is a human-powered transport, human-powered or motorized bicycle, motor-assisted, bicycle pedal, pedal-driven, single-track vehicle, with two bicycle wheel, wheels attached to a bicycle frame, 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 there were more than 1 billion bicycles. There are many more bicycles than cars. Bicycles are the principal Mode of transport, means of transport in many regions. They also provide a popular form of recreation, and have been adapted for use as Toy, children's toys. Bicycles are used for Physical fitness, fitness, Military bicycle, military and Police bicycle, police applications, Bicycle messenger, courier services, Cycle sport, bicycle racing, and artistic cycling. The basic shape and configuration of a typical Safety bicycle, upright or "safety" bicycle, has changed lit ... [...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 ...

Bicycle Wheel
A bicycle wheel is a wheel, most commonly a wire wheel, designed for a bicycle. A pair is often called a wheelset, especially in the context of ready built "off the shelf" performance-oriented wheels. Bicycle wheels are typically designed to fit into the bicycle frame, frame and bicycle fork, fork via Dropout (bicycle part), dropouts, and hold bicycle tires. Invention The first wheel to use the tension in wire wheel, metal spokes was invented by George Cayley, Sir George Cayley to achieve lightness in his 1853 glider. Construction The first bicycle wheels followed the traditions of carriage building: a wooden hub, a fixed steel axle (the bearings were located in the fork ends), wooden spokes and a shrink fitted iron tire. A typical modern wheel has a metal hub, wire tension spokes and a metal or carbon fiber rim which holds a pneumatic rubber tire. Hub A hub is the center part of a bicycle wheel. It consists of an axle, bearing (mechanical), bearings and a hub shell. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Luggage Carrier
A luggage carrier, also commonly called a (bicycle) rack, is a device attached to a bicycle to which cargo or panniers can be attached. This is popular with utility bicycles and touring bicycles. Bicycle luggage carriers may be mounted on the front or rear of a bicycle. The rear mount is more common. Racks on the front are mostly reserved for utility and cargo bikes. A special type of front rack is a low rider which is mainly used for bicycle touring. The term luggage carrier can also refer to a device with two wheels used to wheel luggage or something of similar weight from one place to another, similar to a dolly (hand truck) but lighter and usually able to be folded up. Mounting Bicycles may have eyelets, tapped with a standard thread, at the dropouts on the rear chainstays, and on the front fork blades. Mounting a bike rack is possible without these eyelets, but requires additional hardware. A style of rack clamps only to the seatpost, does not require eyelets or add ...

Chain Guard
A chain is a serial assembly of connected pieces, called links, typically made of metal, with an overall character similar to that of a rope in that it is flexible and curved in compression but linear, rigid, and load-bearing in tension. A chain may consist of two or more links. Chains can be classified by their design, which can be dictated by their use: * Those designed for lifting, such as when used with a hoist; for pulling; or for securing, such as with a bicycle lock, have links that are torus-shaped, which make the chain flexible in two dimensions (the fixed third dimension being a chain's length). Small chains serving as jewellery are a mostly decorative analogue of such types. * Those designed for transferring power in machines have links designed to mesh with the teeth of the sprockets of the machine, and are flexible in only one dimension. They are known as roller chains, though there are also non-roller chains such as block chains. Two distinct chains can be co ...

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 ...

Fender (vehicle)
Fender is the American English term for the part of an automobile, motorcycle or other vehicle body that frames a wheel well (the fender underside). Its primary purpose is to prevent sand, mud, rocks, liquids, and other road spray from being thrown into the air by the rotating tire. Fenders are typically rigid and can be damaged by contact with the road surface. Sticky materials, such as mud, may adhere to the smooth outer tire surface, while smooth, loose objects, such as stones, can become temporarily embedded in the tread grooves as the tire rolls over the ground. These materials can be ejected from the tire's surface at high velocity as the tire imparts kinetic energy to the attached objects. For a vehicle moving forward, the top of the tire rotates upward and forward and can throw objects into the air at other cars or pedestrians in front of the vehicle. In British English, the fender is called the wing. (This may refer to either the front or rear fenders. However, in mode ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dropout (bicycle Part)
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 ...

Bicycle Fender
On a bicycle, a fender American English or mudguard British English is a part that encloses a tire so that it stops spray of water, sand, mud, stones and other road debris from thrown into the air by the rotating wheel. Full-covering fenders go over most of the upper side of the tire, and are considered standard equipment on utility bikes. Sports bikes can have smaller fenders or be completely fenderless, especially on bikes made for use in drier climates. Fenders (mudguards) have an additional cost and contributes to extra weight on the bike, but have the benefits of keeping the cyclist's legs, trousers and back drier, as well as preventing paint damage, preventing eye damage to passengers in bicycle trailers, and being able to provide lower aerodynamic drag. The spray can be clearly noticed when cycling behind another rider in wet conditions, such as when cycling in pelotons, and some clubs require the use of a rear fenders when training in the winter. To mount fenders, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
