The Most Dangerous Biker Gangs in America

Biker gangs are motorcycle clubs that engage in organized crime. These gangs attracted national attention after a week-long brawl with the American Motorcycle Association (AMA) in 1947. This event led the AMA president to declare that 99% of motorcyclists are law-abiding citizens, demonstrating that 1% of motorcyclists are outlaws. The term one-percenter was then coined to refer to these motorcycle gangs.

While there are over three hundred outlaw biker gangs in the USA, here are SIX of the biggest, most notorious outlaw motorcycle clubs considered a real thorn for American Law Enforcement.

Membership – 2500

Major Presence – California

Perhaps the best- known and most dangerous one-percenter in the US is Hells Angels. This gang has a large concentration in California. It boasts 230 chapters in the US with members in 26 other countries. Hells Angels are all about violence, freedom, and reputation. The members of this gang participate in all types of crime. These guys have faced charges ranging from kidnapping, rape, racketeering, murder, assault, robbery, drug dealing, etc.

According to the Department of Justice, this biker gang plays a significant role in the manufacture and distribution of LSD, methamphetamine, heroin, hashish, Ecstasy, and PCP.

It may come as a surprise, but Hells Angels have a business license and a Hells Angels Website. It is a fully-incorporated club that thrives on criminal activities.


2. Bandidos


Year Founded – 1966

Membership – 5000 worldwide

Major Presence – South (Texas)

This biker gang came into prominence after a shootout with the Cossacks gang left nine dead, 18 injured, and 170 bikers placed under arrest in Waco, Texas, in 2015. The club has since come out of the American underworld to be declared a Tier-2 gang. This is the second-most dangerous classification by the Texas Department of Public Safety.

Bandidos have built a fearsome reputation around their gruesome activities. In the 1970s, the founder Donald Chambers killed two Mexican drug dealers after making them dig their graves. The violence perpetrated by this gang involves turf wars with other biker gangs.

After the Waco shootout, Bandidos are listed as one of the Big Four Outlaw Motorcycle Clubs by the FBI. Apart from violent crimes, this gang traffics drugs across the Mexican-Texas border. It is heavily involved in the distribution of methamphetamine, marijuana, and cocaine.


3. Mongols


Year Founded – 1969

Membership – 2000

Major Presence – Southern California

Mongols are best known for their multiple turf wars with the Hells Angels gang. This club was formed as an alternative to Hells Angels since it allowed minority groups to join. It mainly consists of Hispanic and Native Americans.

Mongols members are around 2000. The gang has chapters in 14 states and ten countries. This biker gang is well-known for extremely violent crimes in Southern California and Los Angeles after winning a turf war against Hells Angels in the 1980s.

Like other outlaw motorcycle clubs, Mongols participate majorly in the illegal drug trade of methamphetamine. Not to mention, money laundering, extortion, and robbery.


4. Pagans


Year Founded – 1957

Membership – 1500

Major Presence – East Coast States of Maryland, Pennsylvania, New York, and New Jersey.

This biker gang did not start as a crime syndicate. Formed in 1957, Pagans was an ordinary motorcycle club until 1965. After veterans joined the club, it would soon join the ranks of criminal activity thanks to the bitterness against the government by veterans in the 1960s.

Pagans dominate the East Coast. The gang has its share of illegal activities from smuggling of illegal drugs like meth, marijuana, and heroine to organized crime. The gang is also known for random assault of civilians, drive-by shootings of former members, and violent brawls with other biker gangs.

This outlaw motorcycle club broadly identifies as the 1%er with patches that say it. They also carry patches with coded numbers and letters aimed at pissing off law enforcement.


5. Outlaws Motorcycle Club

Outlaws Motorcycle Club

Year Founded 1935

Membership – 1700+

Major Presence – Florida

The Outlaws Motorcycle Club is the oldest biker gang in the US. It is the top-most 1%er and is respected by other gangs. It started in 1935 but reorganized in the 1950s changing its original patch from a winged motorcycle to a skull with two pistons.

This biker gang has support clubs like the Black Pistons Motorcycle Club which serves as a recruitment club. It is a super strict gang when it comes to riding and brotherhood rules. Its members are men who own a Harley Davidson motorcycle. Women are considered property and can even be exchanged for drugs.

As one of the Big Four biker gangs in the US, this gang has a long and dark history. The members are suspects of murder, execution-style shootings, drug dealing, money laundering, extortion, shootouts, and firebombs. The gang is has a reputation for exacting revenge and have ongoing friction with Hells Angels. They even have an Acronym “ADIOS” meaning “Angels Die in Outlaw States” as a warning to the Hells Angels gang. The club motor is “God Forgives Outlaws Don’t”.


6. Vagos Motorcycle Club

Vagos Motorcycle Club

Year Founded – 1965

Membership – 4000

Major Presence – Western United States

The Vagos Motorcycle Club came up in Southern California. This biker gang has over 4000 members. Unlike other outlaw motorcycle clubs, Vagos is involved in both legal and illegal activities.

The club identifies as an intricate organization with bylaws and legitimate businesses. But this is only one side of the club because its members are wanted for highway shootings, murder, and racketeering. The gang majorly deals with drug and weapon smuggling in the US and across the Mexican border. In a 2011 raid, eight pounds of methamphetamine, 40 pounds of cocaine and a rocket launcher were seized.

Like other gangs, Vagos also frictions with Hells Angels and has been involved in numerous gang shootouts. The Vagos gang has been infiltrated a few times by the ATF, but efforts to bring them down have not borne fruit. The gang has even won twice against law enforcement in defamation charges.


They may spot flashy leather jackets and edge. But outlaw motorcycle clubs are highly structured criminal syndicates. The biker gangs listed here are just a few of the most notorious outlaw motorcycle clubs in the USA. They pause a real threat to public safety, and Federal Law enforcement continues to put a significant focus on them.
