A bicycle, also called a pedal cycle, bike, push-bike or cycle, is a human-powered or motor-assisted, pedal-driven, single-track vehicle, with two wheels attached to a frame, one behind the other. A bicycle rider is called a cyclist, or bicyclist.
A tandem bicycle or twin is a form of bicycle designed to be ridden by more than one person. The term tandem refers to the seating arrangement, not the number of riders. Patents related to tandem bicycles date from the mid 1880s. Tandems can reach higher speeds than the same riders on single bicycles, and tandem bicycle racing exists. As with bicycles for single riders, there are many variations that have been developed over the years.
A tricycle, sometimes abbreviated to trike, is a human-powered three-wheeled vehicle.
The ambiguous term bicycle rack or bike rack may refer to:
A bicycle-sharing system, bike share program, public bicycle scheme, or public bike share (PBS) scheme, is a shared transport service where bicycles are available for shared use by individuals at low cost.
A fixed-gear bicycle is a bicycle that has a drivetrain with no freewheel mechanism such that the pedals always will spin together with the rear wheel. The freewheel was developed early in the history of bicycle design but the fixed-gear bicycle remained the standard track racing design. More recently the "fixie" has become a popular alternative among mainly urban cyclists, offering the advantage of simplicity compared with the standard multi-geared bicycle.
An electric bicycle is a motorized bicycle with an integrated electric motor used to assist propulsion. Many kinds of e-bikes are available worldwide, but they generally fall into two broad categories: bikes that assist the rider's pedal-power and bikes that add a throttle, integrating moped-style functionality. Both retain the ability to be pedaled by the rider and are therefore not electric motorcycles. E-bikes use rechargeable batteries and typically are motor-powered up to 25 to 32 km/h. High-powered varieties can often travel more than 45 km/h (28 mph).
Many countries have enacted electric vehicle laws to regulate the use of electric bicycles, also termed e-bikes. Some jurisdictions have regulations governing safety requirements and standards of manufacture. The members of the European Union and other regions have wider-ranging legislation covering use and safety.

The Center for Appropriate Transport (CAT) was a non-profit community center dedicated to bicycles and alternative transport located in Eugene, Oregon, United States.
A pedelec or EPAC, is a type of low-powered electric bicycle where the rider's pedalling is assisted by a small electric motor. However, unlike some other types of e-bikes, pedelecs are classified as conventional bicycles in many countries by road authorities rather than as a type of electric moped. Pedelecs include an electronic controller which cuts power to the motor when the rider is not pedalling or when a certain speed – usually 25 km/h (16 mph) or 32 km/h (20 mph) – is reached. Pedelecs are useful for people who ride in hilly areas or in strong headwinds. While a pedelec can be any type of bicycle, a pedelec city bike is very common. A conventional bicycle can be converted to a pedelec with the addition of the necessary parts, e.g., motor, battery, etc.
Cyclecide is an American bicycle club based in San Francisco, California, composed of clowns, altered bikes, and a traveling show called "The Bike Rodeo", which is a public performance, and not a bicycle rodeo, a children's bicycle safety clinic.
A bicycle carrier, also commonly called a bike rack, is a device attached to an automobile or bus for transporting bicycles.

Melon Bicycles was a folding bicycle manufacturer based in Chapel Hill, North Carolina. Many cyclists refer to the company as Melon Bikes, Melon Bicycles, or simply Melon. Melon Bicycles went out of business in 2014.
The popularity of cycling in Malta as a sport, a means of commuting, and as a way of exploring the island of Malta is on the increase. In recent years, the Maltese authorities, most notably the Malta Transport Authority, have worked hard to make this activity more accessible and safer.
Cycling infrastructure is all infrastructure cyclists are allowed to use. Bikeways include bike paths, bike lanes, cycle tracks, rail trails and, where permitted, sidewalks. Roads used by motorists are also cycling infrastructure, except where cyclists are barred such as many freeways/motorways. It includes amenities such as bike racks for parking, shelters, service centers and specialized traffic signs and signals. The more cycling infrastructure, the more people get about by bicycle.
The Massachusetts Bay Transportation Authority operates subway, bus, commuter rail, and ferry service in the Greater Boston region. Boston has some of the highest rates of non-motorized commuting in the United States, including high bicycle usage. The MBTA offers certain provisions for riders wishing to make part of their trips by bicycle. The agency allows bicycles to be carried on all fixed-route services except the Green Line and the Ashmont-Mattapan High Speed Line light rail lines, although they are restricted on the commuter rail and heavy rail subway services at peak hours. Bicycle storage areas are offered at many stations, with "Pedal and Park" locking bicycle cages at certain high-usage stations.
