A fitness bicycle (also known as exercise bicycle, exercise bike, or exercycle) is a device with saddle, pedals, and some form of handlebars arranged as on a bicycle, but used as exercise equipment rather than transportation.
An exercise bicycle is usually a special-purpose exercise machine resembling a bicycle without true wheels, but 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.
A cycloergometer, cycle ergometer or bicycle ergometer is a stationary bicycle with an ergometer to measure the work done by the exerciser.
Exercise machines resembling modern stationary bicycles have existed since the end of the eighteenth century; the Gymnasticon was a prominent early example. In recent years, many new stationary bikes have appeared, including those in recumbent positions, upright bikes and indoor cycling bikes which are bikes built for riding in indoor cycling classes.
Types of exercise bicycle
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 increases the intensity of the exercise. Resistance mechanisms include magnets, fans, and friction mechanisms. Some models allow the user to pedal backwards to exercise antagonist muscles which are not exercised in forward pedaling.
Mini exercise bikes comprise the pedal and resistance parts only, with no saddle or handlebars; they are intended for taking exercise, not for training for bicycle riding. They can be placed on the floor and pedalled by a user seated on a chair; the pedals can also be turned with the hands for a different form of exercise. These devices occupy less space than other types and are significantly cheaper; it can be problematic to install them in a way which prevents them from moving out of position when pedalling.
Uses of exercise bicyclesExercise bikes are used for exercise, to increase general fitness, and for training for cycle events. The exercise bike has long been used for physical therapy because of the low-impact, safe, and effective cardiovascular exercise it provides. The low-impact movement involved in operating an exercise bike does not put much stress on joints and does not involve sporadic motions that some other fitness equipment may require.
Stationary bikes are also used to exercise for weight loss. Veloergometers (e.g. CEVIS) are used in space (e.g. in the ISS) to counter cardiovascular deconditioning in the microgravity environment.
The term road bicycle is used to describe bicycles built for traveling at speed on paved roads. Some sources use the term to mean racing bicycle. Other sources specifically exclude racing bicycles from the definition, using the term to mean a bicycle of a similar style but built more for endurance and less the fast bursts of speed desired in a racing bicycle; as such, they usually have more gear combinations and fewer hi-tech racing features. Certain of these bicycles have been referred to as 'sportive' bicycles to distinguish them from racing bicycles.
Compared to other styles of bicycle, road bicycles share common features:
The tires are narrow, high-pressure, and smooth to decrease rolling resistance.
They usually use derailleur gears; however, single-speed and fixed-gear varieties exist.
The bicycle is of a lightweight construction.
The term road bicycle can also describe any type of bike used primarily on paved roads, in contrast to bikes primarily intended for off-road use, such as mountain bikes. Several variations of road bikes include:
Touring bicycles are designed for bicycle touring: they are robust, comfortable, and capable of carrying heavy loads.
Hybrid bicycles are designed for a variety of recreational and utility purposes. While primarily intended for use on pavement, they may also be used on relatively smooth unpaved paths or trails.
Utility bicycles are designed for utility cycling: are a traditional bicycle for commuting, shopping and running errands in towns and cities.

Recumbent bicycles are designed for variety of recreational and utility purposes, but are characterised by the reclined riding position in which the cyclist is seated.

Vintage road bicycles, also known as classic lightweight bicycles, are generally older bicycles with frames which are manufactured using steel tubing and lugs. Certain examples of this bicycle type have become collectors' items, with potential values of several thousand dollars. Other cyclists prefer this type of bicycle to those manufactured using modern techniques because they are "practical, versatile, durable, repairable, and timeless, regardless of current popular trends."
A flat bar road bike, also called a fitness bike is a relatively new style of bicycle. It is simply a road bike fitted with MTB-style shifters, brake levers and a flat handlebar.This combination provides a light, fast bike with a more upright and neutral riding position. A flat bar road bike is most commonly used for commuting, urban and fitness riding.
