Biker clubs or motorcycle clubs are organized groups of motorcycle riders who may participate in group riding events, charity drives, social events or rallies. Motorcycle clubs typically have a logo or series of patches awarded and worn by members representing status within the club or beliefs held by the club.
Most of the established motorcycle clubs in the United States are law-abiding groups of riders who share the common interest of riding motorcycles. Club membership may be restricted based on factors such as motorcycle make and style of motorcycle. Other types of motorcycle clubs include police, military, fire and emergency medical personnel-only groups. Outlaw motorcycle clubs, known as one-percenter motorcycle clubs, are motorcycle clubs whose members participate in organized crime and other illicit activity. More loosely organized motorcycle clubs, known as riding clubs, are groups that organize rides for members but don't require attendance to club functions or payment of dues.
