The Hells Angels Motorcycle Club (HAMC) is a worl-wide motorcycle club whose members typically ride Harley-Davidson motorcycles. In the United States and Canada, the Hells Angels are incorporated as the Hells Angels Motorcycle Corporation. Some members of the Hells Angels and other motorcycle clubs nickname themselves "one-percenters" in response to the American Motorcyclist Association (AMA) claim, made after the infamous Hollister affair, that ninety-nine percent of motorcyclists were law abiding citizens, and the other one percent were troublemakers giving everyone else a bad name.
