What does biker mean?
A biker is a person who rides a motorcycle, particularly one who does so enthusiastically or as part of motorcycle culture. In its dominant modern usage, especially in American English, the term evokes images of leather jackets, powerful machines, and the camaraderie of riding clubs, ranging from weekend hobbyists to members of organized motorcycle groups. In British English the word has a second, broader sense, referring simply to someone who rides a bicycle — a meaning that survives alongside the motorcycling one. The noun is formed from 'bike', itself an informal clipping of either 'bicycle' or 'motorbike'. Common collocations include 'biker gang', 'biker jacket', and 'biker boots', reflecting both the subculture and the distinctive fashion associated with it. Because 'biker' overlaps with 'cyclist' and 'rider', context usually determines which kind of two-wheeler is meant, though the motorcycling sense predominates worldwide today.
A person who rides a motorcycle, especially an enthusiast or member of motorcycle culture.
"The highway diner was a favorite stop for bikers travelling Route 66."
This is the dominant sense in both British and American English.
A person who rides a bicycle; a cyclist.
"The new cycle lane is used by hundreds of bikers every morning."
Chiefly British English; less common than the motorcycling sense.
Regular plural, used when referring to multiple riders or the group collectively.
"Bikers from across the country converged on the small town for the rally."
Despite the leather-and-chrome image, the word 'biker' originally just meant anyone who rode a bike — pedal-powered or not — and only narrowed to motorcyclists in the mid-20th century.

Etymology of biker
'Biker' derives from 'bike', a late 19th-century informal shortening of 'bicycle', which itself comes from Greek roots: 'bi-' meaning 'two' and 'kyklos' meaning 'wheel' or 'circle'. The suffix '-er' forms agent nouns denoting a person who performs an action, so a biker is literally 'one who bikes'. Originally applied to riders of any bicycle, the word gradually came to be associated chiefly with motorcycles during the 20th century as motorized biking developed its own distinct culture, while 'cyclist' took over as the standard term for pedal-powered riders in most varieties of English.
How biker is actually used
The dominant sense is the motorcyclist, and in popular culture the word carries connotations of rebellion, leather jackets, and outlaw clubs (reinforced by films like Easy Rider). In British English, especially in cycling contexts, 'biker' can simply mean a cyclist. The word is informal to neutral in register.
Easily confused with biker
In American English a biker rides a motorcycle while a cyclist rides a bicycle; in British English 'biker' can mean either.
