Trainer (bicycling)
A bicycle trainer is a piece of equipment that makes it possible to ride a bicycle while it remains stationary. They are commonly used to warm up before races, or when riding conditions outside are not favorable. Operation A trainer consists of a frame, a clamp to hold the bicycle securely, a roller that presses up against the rear wheel, and a mechanism that provides resistance when the pedals are turned. In a wind trainer, the roller drives fan blades that create air resistance. These are typically the least expensive and noisiest trainers. Magnetic trainers have magnets and a conducting flywheel operating as an eddy current brake. They are moderately expensive and moderately noisy. Some magnetic trainers have handlebar-mounted control boxes to change the level of resistance during a training session. Fluid trainers use liquid-filled chambers to create resistance. They are the most expensive and quietest trainers. A small number of trainers use a centrifugal pressure mecha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Giant TCX On Cycleops Fluid 2
In folklore, giants (from Ancient Greek: ''gigas'', cognate giga-) are beings of human-like appearance, but are at times prodigious in size and strength or bear an otherwise notable appearance. The word ''giant'' is first attested in 1297 from Robert of Gloucester's chronicle. It is derived from the ''Gigantes'' ( grc-gre, Γίγαντες) of Greek mythology. Fairy tales such as ''Jack the Giant Killer'' have formed the modern perception of giants as dimwitted ogres, sometimes said to eat humans, while other giants tend to eat the livestock. The antagonist in ''Jack and the Beanstalk'' is often described as a giant. In some more recent portrayals, like those of Jonathan Swift and Roald Dahl, some giants are both intelligent and friendly. Literary and cultural analysis Giants appear in the folklore of cultures worldwide as they represent a relatively simple concept. Representing the human body enlarged to the point of being monstrous, giants evoke terror and remind humans of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Knobby Tire
Off-road tires (Off-road tyre) are a category of vehicle tires that use deep tread to provide more traction on unpaved surfaces such as loose dirt, mud, sand, or gravel. Compared to ice or snow tires, they lack studs but contain deeper and wider grooves meant to help the tread sink into mud or gravel surfaces. Design Off-road tires are typically radials with thick, deep tread. On dirt surfaces, the exposed edges of the tread dig into soft ground to give more traction than rolling friction alone, analogous to the traction provided by cleated shoes. These off-road tires provide their maximum grip on loose surfaces, but on paved surfaces the smaller contact patch affords less traction as compared to street tires. Tires with less aggressive knobs (smaller knobs and the shape of the tread cross-section closer to that of street tires) can provide a compromise, giving less grip off-road, but a grip closer to that of street tires on paved surfaces. Such tires are useful for enduro and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spinning (cycling)
Spinning is a brand of indoor bicycles and indoor cycling instruction classes distributed and licensed by the American health and fitness company Mad Dogg Athletics. Launched in 1993, the brand has become a popular term to refer to indoor bicycles and indoor cycling fitness classes in the United States and throughout the world. History The Spinning indoor cycling program was developed by South African endurance bicycle racer Johnny Goldberg (known as Johnny G) in the mid-1980s after he was struck by a car while training for a race at night. Goldberg's early Spinning prototypes were targeted toward endurance athletes as a substitute for outdoor bicycle training, and allowed the athlete to train year-round regardless of outdoor weather conditions. In 1989 Goldberg opened the Johnny G Spinning Center, in Santa Monica, California, with bikes he built. In 1992 he moved the class to Karen Voight Fitness, in Hollywood, for more exposure. In 1993 Goldberg and his business partner, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Outline Of Cycling
:''This article is an outline about the activity of cycling. For an outline about bicycles themselves, see outline of bicycles.'' :The following ''outline'' is provided as an overview of, as well as a topical guide to cycling: Cycling, also called bicycling or biking, is the activity of using / riding bicycles, (at least partially) human-powered, wheeled vehicles (typically by foot pedalling), for purposes including transport, recreation, social interaction, exercise, sport, therapy, other purposes, or any combination thereof. Persons engaged in cycling are called cyclists, bikers, or sometimes bicyclists. They typically either dress for where they are going, or for the cycling, sometimes having another set of clothing with them, or arranged. Apart from regular two-wheeled bicycles, cycling also includes riding unicycles, tricycles, quadricycles, and other similar human-powered wheeled vehicles (HPVs). Some bicycles are sold with (electric) motors (e-bikes), or ot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bicycle Tire
A bicycle tire is a tire that fits on the wheel of a bicycle or similar vehicle. These tires may also be used on tricycles, wheelchairs, and handcycles, frequently for racing. Bicycle tires provide an important source of suspension, generate the lateral forces necessary for balancing and turning, and generate the longitudinal forces necessary for propulsion and braking. Although the use of a pneumatic tire greatly reduces rolling resistance compared to the use of a rigid wheel or solid tire, the tires are still typically, the second largest source, after wind resistance (air drag), of power consumption on a level road. The modern detachable pneumatic bicycle tire contributed to the popularity and eventual dominance of the safety bicycle. Bicycle tires are also used on unicycles, tricycles, quadracycles, tandem bicycles, hand cycles, bicycle trailers, and trailer bikes. History The first bicycle "tires" were iron bands on the wooden wheels of velocipedes. These were fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bicycle Rollers
Bicycle rollers are a type of bicycle trainer that make it possible to ride a bicycle indoors without moving forward. However, unlike other types of bicycle trainers, rollers do not attach to the bicycle frame, and the rider must maintain balance on the rollers while training. Bicycle rollers normally consist of three cylinders, drums, or "rollers" (two for the rear wheel and one for the front), on top of which the bicycle rides. A belt connects the middle roller to the front roller, causing the front wheel of the bicycle to spin when the bicycle is pedaled. The spacing of bicycle rollers can usually be adjusted to match the bicycle's wheelbase. Generally, the front roller is adjusted to be slightly ahead of the hub of the front wheel. History Bicycle rollers are nearly as old as the bicycle itself. Mile-a-minute Murphy is pictured riding on them as early as 1901. Riding on rollers Balancing the bicycle without riding off the rollers is an extra challenge for the rider and req ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zwift
Zwift is a massively multiplayer online cycling and running physical training program that enables users to interact, train, and compete in a virtual world. Zwift was developed by Zwift Inc., which was co-founded by Jon Mayfield, Eric Min, Scott Barger, and Alarik Myrin, in California, United States, North America, in 2014.

Min, a lifelong cyclist, found himself confined to riding indoors, and dissatisfied with current interactive options, he believed he could improve on them by "making cycling social". Around this time, Min saw an online post by programmer Jon Mayfield describing a "3D trainer program" he was developing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cogset
On a bicycle, the cassette or cluster is the set of multiple sprockets that attaches to the hub on the rear wheel. A cogset works with a rear derailleur to provide multiple gear ratios to the rider. Cassettes come in two varieties, freewheels or cassettes, of which cassettes are a newer development. Although cassettes and freewheels perform the same function and look almost the same when installed, they have important mechanical differences and are not interchangeable. Freewheels A freewheel (also known as a block) consists of either a single sprocket or a set of sprockets mounted on a body which contains an internal ratcheting mechanism and mounts on a threaded hub. Threaded rear hubs were available in different thread patterns depending on the country of manufacture, French and British threads being the most common. British C.E.I. (Cycle Engineers Institute) thread was adopted as the international standard and is now known as B.S.C. (British Standard Cycle). It is a standar ...

Stationary Bicycle
A stationary bicycle (also known as exercise bicycle, exercise bike, spinning bike, spin bike, or exercycle) is a device used as exercise equipment for indoor cycling. It includes a saddle, pedals, and some form of handlebars arranged as on a (stationary) bicycle. A stationary bicycle is usually a special-purpose exercise machine resembling a bicycle without wheels. It is also possible to adapt an ordinary bicycle for stationary exercise by placing it on bicycle rollers or a trainer. Rollers and trainers are often used by racing cyclists to warm up before racing, or to train on their own machines indoors. History The ancestors of modern stationary bicycles date back to the end of the eighteenth century. The Gymnasticon was an early example. Types Some models feature handlebars that are connected to the pedals so that the upper body can be exercised along with the lower body. Most exercise bikes provide a mechanism for applying resistance to the pedals which increas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eddy Current Brake
An eddy current brake, also known as an induction brake, electric brake or electric retarder, is a device used to slow or stop a moving object by generating eddy currents and thus dissipating its kinetic energy as heat. Unlike friction brakes, where the drag force that stops the moving object is provided by friction between two surfaces pressed together, the drag force in an eddy current brake is an electromagnetic force between a magnet and a nearby conductive object in relative motion, due to eddy currents induced in the conductor through electromagnetic induction. A conductive surface moving past a stationary magnet develops circular electric currents called eddy currents induced in it by the magnetic field, as described by Faraday's law of induction. By Lenz's law, the circulating currents create their own magnetic field that opposes the field of the magnet. Thus the moving conductor experiences a drag force from the magnet that opposes its motion, proportional to its veloc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
