List of 1 percenter motorcycle clubs in california

California is the undisputed birthplace of the one-percenter motorcycle club culture. Following World War II, returning veterans sought the brotherhood and adrenaline of the military, buying surplus Harley-Davidson and Indian motorcycles to form riding clubs across the Golden State. The infamous 1947 Hollister rally—and the American Motorcyclist Association’s subsequent alleged claim that 99 percent of riders were law-abiding—birthed the “1%er” diamond patch, a badge worn by those proudly operating outside mainstream society. Over the decades, these loosely organized renegades evolved into highly structured, international syndicates, turning California’s vast highways into the ultimate battleground for territorial supremacy and exporting their subculture to the rest of the globe.

The Titans: International 1%er Clubs Born in California

California is the proving ground where the world’s most recognizable outlaw motorcycle clubs first planted their flags, expanding from local brotherhoods into massive international empires.

Hells Angels MC

• Founded: 1948 in Fontana, California
• Colors: Red and White
• Insignia: The iconic “Death’s Head” winged skull

The Hells Angels Motorcycle Club is the most famous and widespread 1%er club in the world, with its roots planted firmly in the dusty town of Fontana. Formed by Otto Friedli and other disaffected World War II veterans, the club quickly established charters across the state. The Oakland charter, later led by the iconic Ralph “Sonny” Barger, became the true epicenter of the club’s culture, establishing the rules, the structured hierarchy, and the iconic “Barger Larger” Death’s Head patch. Under Barger’s charismatic leadership, the Hells Angels expanded far beyond California’s borders, eventually opening charters on every major continent while maintaining a massive, unyielding grip on their West Coast homeland.

Mongols MC

• Founded: 1969 in Montebello, California
• Colors: Black and White
• Insignia: Genghis Khan riding a motorcycle with a scimitar

The Mongols Motorcycle Club was forged in East Los Angeles by a tight-knit group of Hispanic Vietnam War veterans who were reportedly denied membership into other clubs due to their race. Refusing to back down, these men formed their own brotherhood, adopting the name of the fierce Mongolian empire and claiming Southern California as their sovereign territory. From their inception, the Mongols were locked in a vicious, decades-long blood feud with the Hells Angels for control of the region, eventually breaking the monopoly over Southern California. Despite numerous massive federal indictments, the brotherhood has survived, thrived, and expanded globally.

Vagos MC

• Founded: 1965 in San Bernardino, California
• Colors: Green and White
• Insignia: Loki, the Norse god of mischief

Established in the gritty, working-class city of San Bernardino, the Vagos originally called themselves the Psychos before settling on a name that translates to “vagabonds” or “wanderers” in Spanish. Adopting Loki as their center patch, the club draped themselves in vibrant green and white, setting themselves apart from traditional red and black color schemes. Operating primarily in the Inland Empire, they earned the nickname “The Green Nation” and became notorious for their militant structure and fierce defense of their turf, frequently clashing with rival clubs over dominance in the high desert. Today, the Vagos boast hundreds of chapters across the Americas.

Satan’s Slaves MC

• Founded: 1960s in the San Fernando Valley, California
• Colors: Black and White
• Insignia: A sinister, horned devil figure

The Satan’s Slaves Motorcycle Club was a formidable one-percenter club that ruled the San Fernando Valley during the golden era of the 1960s and 70s. Known for riding stripped-down, high-performance choppers and embracing a raw outlaw lifestyle, the Slaves were considered one of the toughest, most exclusive clubs in Southern California. Unlike many clubs that immediately engaged in warfare, they maintained a complex but respectful relationship with the Hells Angels, riding together at massive runs. In the late 1970s, the majority of the Slaves accepted an offer to patch over to the Hells Angels, permanently etching their legacy into California biker history.

The Historic Vanguard: Early Outlaw Clubs of the Golden State

Before the modern mega-clubs dominated the headlines, California was home to pioneering organizations that laid the groundwork, traditions, and unwritten rules of the 1%er lifestyle.

Gypsy Joker MC

• Founded: 1956 in San Francisco, California
• Colors: Black and White
• Insignia: A laughing, menacing court jester

Born in the misty, bohemian streets of San Francisco on April Fools’ Day, the Gypsy Jokers were the undisputed kings of the city long before other clubs secured a monopoly over the Bay Area. They were wild, rebellious, and deeply entrenched in the early outlaw chopper scene, earning a fierce reputation for defending their turf. Throughout the 1960s, a bitter and violent rivalry erupted with the rapidly expanding Hells Angels. Facing a numerically superior enemy, the Gypsy Jokers made a historic decision to migrate north, eventually establishing a massive and unbreakable stronghold in the Pacific Northwest and Australia.

Chosen Few MC

• Founded: 1959 in Los Angeles, California
• Colors: Black and White
• Insignia: A white cross over a red shield

The Chosen Few Motorcycle Club holds a groundbreaking place in outlaw biker history as the first fully integrated 1%er club in the United States. Founded in South Central Los Angeles by a group of African American riders, the club defied the intense racial segregation of the era by openly welcoming white, Hispanic, and Asian members. Their refusal to conform earned them immense respect from some and bitter hostility from others. They forged an identity based solely on a man’s character, loyalty, and his ability to ride, prioritizing brotherhood over senseless territorial disputes.

Galloping Goose MC

• Founded: 1942 in Los Angeles, California
• Colors: Purple and Black

One of the oldest outlaw motorcycle clubs in existence, the Galloping Goose predate almost every modern 1%er organization, having formed during the height of World War II. Starting as an informal group of racing enthusiasts, their name was a tongue-in-cheek reference to a popular rude hand gesture of the era, showcasing their inherent anti-establishment attitude. They played a foundational role in shaping California’s biker culture, heavily involved in pioneering the stripped-down, customized chopper aesthetic. Today, their purple and black colors remain a rare but highly revered sight in the Western United States.

Pissed Off Bastards of Bloomington (POBOB)

• Founded: 1945 in Bloomington, California
• Colors: Blue and Gold
• Insignia: A smirking baby in a diaper

Widely known by their acronym POBOB, this club is composed of the legendary forefathers of the California 1%er movement. Formed by combat-hardened veterans just south of San Bernardino, they were among the first to organize into a formal, uniformed motorcycle club. POBOB is most famous for their heavy involvement in the 1947 Hollister rally, which cemented their place in history as the original “outlaws.” Shortly after the event, severe internal disagreements split the club, leading prominent member Otto Friedli to break away and form the Hells Angels. Despite this, POBOB reorganized and remains active today.

Devils Diciples MC

• Founded: 1967 in Fontana, California
• Colors: Blue and White
• Insignia: A wheel with crossed tridents

Intentionally misspelled as “Diciples” to distance themselves from religious connotations, this club originated in the biker hotbed of Fontana. From their inception, they established themselves as a no-nonsense brotherhood that refused to be intimidated by the larger clubs operating in Southern California. Though born on the West Coast, the Devils Diciples found their greatest strength by expanding eastward, establishing massive strongholds in the Midwest. Despite their heavy presence in states like Michigan and Ohio today, the club’s California roots remain a vital part of their gritty, highly organized identity.

Peckerwoods MC

• Founded: 1978 in Santee, California
• Colors: Blue and White

Emerging from the working-class suburbs of San Diego, the Peckerwoods MC was born out of a tight-knit brotherhood known for an aggressive stance and a fierce dedication to local turf. The club reclaimed a historically derogatory term for poor whites, wearing it as a badge of honor to signify their rugged, blue-collar roots. While they never sought massive international expansion, their sheer ferocity made them an immovable force in San Diego County. They have often aligned themselves with larger dominant clubs for strategic survival while fiercely maintaining their own distinct blue-and-white identity.

East Bay Dragons MC

• Founded: 1959 in Oakland, California
• Colors: Gold and Black
• Insignia: A fiery green dragon

Originating as an all-Black car club before transitioning exclusively to Harley-Davidson motorcycles, the East Bay Dragons hold legendary status in the Bay Area. Founded by Tobie Gene Levingston during an era of intense civil rights struggles, the Dragons rode heavy, customized choppers as a powerful symbol of Black independence and rebellion. While they do not traditionally wear the 1% diamond, they are universally respected within the outlaw community. They formed a historic, enduring alliance with the Oakland Hells Angels in the 1960s, based on a shared rejection of mainstream authority and a deep love for motorcycles.

Top Hatters MC

• Founded: 1947 in Hollister, California
• Colors: Black and Red

Tracing their origins straight to the symbolic Mecca of the outlaw biker world, the Top Hatters boast one of the most incredible pedigrees in California. Initially formed as a family-oriented riding club, they were present during the infamous 1947 Hollister riot and evolved alongside the subculture to become a hardened, widely respected outlaw club. Fiercely protective of their city, they act as the undisputed hosts for the thousands of bikers who make the pilgrimage to the Hollister Independence Rally every year. Their black and red colors signal their untouchable status as original architects of the biker lifestyle.

The Gritty Underworld: Fierce California Biker Brotherhoods

The lower tiers and fiercely independent clubs of California make up the dangerous, unpredictable underworld of the 1%er scene, surviving through sheer toughness and an iron-fisted grip on their own destinies.

Hessians MC

• Founded: 1968 in Southern California
• Colors: Black and White
• Insignia: A death’s head pierced by a sword

Exploding onto the scene in Orange County, the Hessians were an ultra-aggressive, chopper-obsessed brotherhood that fully embraced the darkest aspects of the outlaw lifestyle. Renowned across the West Coast for building high-performance custom motorcycles, they combined elite craftsmanship with a genuinely terrifying street presence. During the 1970s, they ran shoulder-to-shoulder with the biggest names in the underworld until severe federal raids crippled their leadership. The Hessians survived by going underground, tightening their ranks, and focusing purely on brotherhood, keeping their sword-pierced skull emblem alive on the highways today.

Henchmen MC

• Founded: San Jose, California
• Colors: Black and Silver/Red
• Insignia: A hooded executioner

Originating in the industrial sectors of San Jose, the Henchmen built their reputation on silence, extreme loyalty, and an absolute refusal to compromise their outlaw values. Founded by hardcore riders who desired a tighter brotherhood away from the politics of the dominant mega-clubs, they handle their business quietly and efficiently. Operating heavily in the shadows, they secured their Northern California territory through sheer grit and a tight chain of command that makes them incredibly difficult for law enforcement to penetrate. Their hooded executioner patch is a strict warning that they protect their own at all costs.

Solo Angeles Club de Motocicletas

• Founded: 1959 in Tijuana, Mexico
• Colors: Black and White
• Insignia: A winged motorcycle tire

While technically founded just across the border, the Solo Angeles are intrinsically tied to the Southern California 1%er culture. As the oldest and most respected motorcycle club in Mexico, they became deeply integrated into the West Coast scene, frequently crossing the border to ride and do business with California’s most notorious clubs. They serve as the ultimate hosts for American bikers making runs into Mexico, famous for organizing massive charity toy runs that blend outlaw culture with community philanthropy. A Solo Angeles patch commands immediate respect as the undeniable kings of the Baja border.

Hangmen MC

• Founded: 1960 in Richmond, California
• Colors: Black and White
• Insignia: A hangman’s noose

Forged in the rough, blue-collar dockyards of Richmond, the Hangmen carved out a fiercely independent identity in the shadow of the Bay Area’s massive motorcycle scene. Known as a working-class brotherhood of hardcore riders, they refused to be pushed around by the larger organizations dominating Oakland and San Francisco. Their chilling hangman’s noose logo perfectly encapsulated their grim, unyielding attitude toward territorial disputes. To secure their future, the Hangmen eventually pushed their influence out of California and into the Pacific Northwest, maintaining their legacy through unbreakable loyalty rather than massive global expansion.
