The English word 'biker' can refer to a motorcyclist, especially one in a subculture, or a cyclist. In Japanese, the translation depends heavily on context. For motorcyclists, common terms include バイカー (baikā) for the subculture, ライダー (raidā) for any rider, and 暴走族 (bōsōzoku) for outlaw gangs. For cyclists, サイクリスト (saikurisuto) is used.

In English, 'biker' can sometimes mean a cyclist, but in Japanese, バイカー (baikā) almost exclusively refers to motorcyclists in a subculture. Using it for a cyclist would cause confusion. Use サイクリスト (saikurisuto) or 自転車乗り (jitensha nori) instead.
ライダー (raidā) is a neutral term for any motorcycle rider, while バイカー (baikā) specifically implies a subcultural identity (leather, clubs, etc.). Use ライダー for general references and バイカー when emphasizing the lifestyle.
