Motorcycle Club Bikers' Tattoos

Other organizations whose activities primarily involve motorcycles exist for a specific purpose, 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. While neither of the latter two groups require a motorcycle for membership, they are motorcycling-oriented and much of their activity involves rides. The Christian Motorcyclists Association is a biker ministry. In the United Kingdom, Freewheelers EVS is one of a number of similar charities, which use motorcycles to provide an out-of-hours emergency medical courier service. Some clubs attract membership from specific groups, such as the Blue Knights Law Enforcement Motorcycle Club, consisting of law enforcement personnel.
The American Motorcyclist Association (AMA) is the largest American motorcyclist organization. It serves as an umbrella organization for local clubs and sporting events. As of March, 2006, the AMA counts 269,884 active members and many chartered clubs. One online directory of MCs lists 216 clubs.
