What does cycle mean?
A cycle is a sequence of events or stages that repeats regularly in the same order, returning to its starting point before beginning again. The word applies across an enormous range of contexts: nature's water and carbon cycles, economic booms and busts known as business cycles, the life cycle of an organism, and the wash or spin cycle of a household machine. It can also refer to a single complete round of such a sequence, or to the period it takes. As a verb, especially in British English, 'cycle' means to ride a bicycle, though it can also describe moving through repeated phases, as when a system cycles on and off. Derived from the Greek 'kyklos,' meaning circle or wheel, the word carries a built-in image of circularity. Its connotations are generally neutral, though phrases like 'vicious cycle' lend it overtones of inescapable repetition, making it useful for describing both natural rhythms and frustrating patterns alike.
A series of events, processes, or stages that recur regularly in the same order.
"The seasons form a natural yearly cycle."
Often used with a specifying modifier (water cycle, sleep cycle, business cycle) to name a particular recurring sequence.
A single complete round or repetition within such a sequence.
"After one full cycle of the program, the results were saved."
To ride a bicycle.
"They cycled along the canal towpath all afternoon."
Common in British English; American speakers more often say 'bike' or 'ride.'
To pass through, or to cause something to pass through, a repeating sequence of states or operations.
"The heating system cycles off once the room reaches temperature."
Standard plural for both the repeating-sequence sense and the machine-operation sense; used identically in British and American English.
"Economists have long debated how best to predict the ups and downs of business cycles."
The word 'cycle' comes from Greek 'kyklos' meaning circle or wheel — which is exactly why a bicycle has two of them.

Etymology of cycle
The English word 'cycle' derives from the ancient Greek 'kyklos,' meaning circle, ring, or wheel, transmitted through Latin as 'cyclus.' It entered English around the seventeenth century, initially in learned contexts referring to recurrent astronomical periods, and later broadened to cover any repeating sequence of events. The same Greek root gives us related words such as 'bicycle,' 'recycle,' and 'cyclone,' all preserving the underlying idea of circularity.

How cycle is actually used
In British English, 'cycle' as a verb commonly means to ride a bicycle; in American English 'bike' or 'ride' is more usual. The noun spans everyday contexts (laundry, exercise) and technical ones (economics, biology, engineering), so register varies with context rather than with the word itself.
Easily confused with cycle
'Psych' means to mentally prepare or intimidate (or slangily 'just kidding'), while 'cycle' refers to a repeating sequence or riding a bicycle — the two merely sound similar.
