Many affiliate with an umbrella organization, such as the British Motorcyclists Federation in the UK, or FEMA in Europe.
Other organizations whose activities primarily involve motorcycles exist for specific purposes or social causes such as the Patriot Guard Riders, who provide funeral escorts for military veterans, and Rolling Thunder, which advocates for troops missing in action and prisoners of war.
[3][4][5] There are numerous religiously oriented clubs such as the Christian Motorcyclists Association, a biker ministry, charities such as Freewheelers EVS, which use motorcycles to provide an out-of-hours emergency medical courier service, and clubs which attract membership from specific groups, such as the Blue Knights Law Enforcement Motorcycle Club, for law enforcement personnel.
Outlaw or one percenter can mean merely that the club is not chartered under the auspices of the American Motorcyclist Association,[10] implying a radical rejection of authority and embracing of the "biker" lifestyle as defined and popularized since the 1950s and represented by such media as Easyriders magazine, the work of painter David Mann and others.
In many contexts the terms overlap with the usual meaning of "outlaw" because some of these clubs, or some of their members, are recognized by law enforcement agencies as taking part in organized crime.
