- Bicycle A bicycle, also known as a bike, pushbike or cycle, is a pedal-driven, human-powered, single-track vehicle, having two wheels attached to a frame, one behind the other. A person who rides a bicycle is called a cyclist or a bicyclist

- Human-powered vehicle Human-powered transport is the transport of person and/or goods using human muscle power. Like animal-powered transport, human-powered transport has existed since time immemorial in the form of walking, running and swimming. Modern technology has allowed machines to enhance human-power

Economics
- Business cycle The term business cycle refers to economy-wide fluctuations in production or economic activity over several months or years. These fluctuations occur around a long-term growth trend, and typically involve shifts over time between periods of relatively rapid economic growth (expansion or boom), and periods of relative stagnation or decline (, economy-wide fluctuations in production or economic activity over several months or years
Mathematics and physics
- Algebraic cycle and Hodge cycle, homology classes in algebraic geometry
- Cycle (graph theory) Chordless cycles are also sometimes called graph holes. A graph antihole is the complement of a graph hole, a nontrivial path in a graph from a node to itself
- Cycle (mathematics) In mathematics, and in particular in group theory, a cycle is a permutation of the elements of some set X which maps the elements of some subset S to each other in a cyclic fashion, while fixing all other elements. The set S is called the orbit of the cycle, a basic permutation (all permutations are products of cycles)
- Cyclic (mathematics) shows other terms in mathematics beginning with cyclic or cycle
- Turn (geometry) or cycle, a unit of plane angle equal to 360 degrees
Music
- Cycle (music), a section of a piece that is repeated or repeatable
- Cyclic form Cyclic form is a technique of musical construction, involving multiple sections or movements, in which a theme, melody, or thematic material occurs in more than one movement as a unifying device. Sometimes a theme may occur at the beginning and end ; other times a theme occurs in a different guise in every part (Berlioz, Symphonie Fantastique), a technique of construction involving multiple sections or movements
