|abums| is the story of an unyielding pursuit — a tribute to legacy, heritage, and the raw, unfiltered joy of gravity-driven mountain biking.Born from over 25 years of passion and precision on the trails — long before it was called "Enduro" — it is a brand engineered by those who ride not just to perform, but to feel.

Forged from more than 25 years of obsession with mountain biking — back when no one called it "Enduro" and it was simply about descending faster, climbing smarter, and feeling every vibration of the earth — |abums| is a tribute to legacy, to craft, and to the timeless spirit of gravity.

It’s not just a bike. It’s the distilled result of decades spent riding, racing, breaking, rebuilding, refining. It’s a machine born from conversations between engineers and mountains. A story of respect — for steel as a material of soulful resilience, for high-pivot suspension as a symbol of balance and boldness, and for the kind of riding that feeds something deeper than adrenaline: presence.

Hand-built with precision, designed with passion, and tested by those who live to ride, |abums| represents a return to what matters. A reminder that performance is not just measured in numbers, but in how alive it makes you feel.

This is more than engineering. This is heritage in motion.

Engineered for gravity. Designed for permanence.

In an age dominated by hyper-optimized carbon frames and mass-produced aluminum bikes, a quiet revolution begins — forged not in a factory, but in a workshop. ABUMS, a new e-bike company born from devotion to the ride, makes its debut with a bold offering: the world’s first electric enduro mountain bike crafted from steel with a fully integrated battery.

This is not a nostalgic revival. It’s a radical reinterpretation of steel as the material of the future — one that prioritizes feel over flash, soul over specs, and permanence over planned obsolescence. ABUMS is designed and hand-built by four mountain bikers with over 25 years of riding under their belts — three mechanical engineers and one industrial designer — who have lived the evolution of what is now called “Enduro” long before the word existed.

“We’ve broken bikes, climbed impossible trails, chased speed, and tasted silence on a mountain descent. That’s what this bike comes from.”

At the heart of the first ABUMS model lies a bespoke High Pivot suspension system, engineered from scratch to deliver a rare blend of climbing finesse and downhill aggression. Unlike traditional systems, the high pivot design allows the rear wheel to move in a rearward arc — mirroring the motion of terrain impacts — which dramatically improves traction and control on technical descents.

But the genius lies in the balance: less pedal kickback, better chain growth control, and an enlarged sweet spot that gives the rider the feeling of control without constant correction. The system has been fine-tuned for performance mountain biking — aggressive, fast, fluid, but never harsh.

This level of performance is supported by a frame that’s anything but ordinary. Each ABUMS is welded by hand using bracing techniques, elevating structural precision into a kind of mechanical poetry. The steel absorbs trail

chatter like no other material, providing a ride quality that is smooth, planted, and alive, transmitting just enough of the terrain to remain connected without ever overwhelming.

“You don’t ride a steel frame. You ride with it. It moves like a partner, not a platform.”

Where most e-MTBs hide their complexity behind bulk, ABUMS integrates its power with discretion. The latest- generation MAHLE motor, is compact, efficient, and minimal.

ABUMS is more than a machine. It is a story of relentless pursuit

—

Of honouring the ride, respecting the legacy of the sport, and reconnecting with the sheer pleasure of pure, gravity-fed mountain biking.

It is a return to first principles, where bikes are built not by marketing departments, but by those who live to ride.

Steel isn’t just a material — it’s a statement. It speaks of durability, timelessness, and a refusal to compromise. It’s how things used to be built — to last, to age with grace, to carry stories in every weld. ABUMS brings that spirit back to the mountain.

“This is not an e-bike. This is our bike. One we’ve imagined for decades. Now, we’ve made it real.”

Foundation

Founded in the Basque Country by four friends bound by trail and time, ABUMS develops high-performance electric Enduro bikes that fuse engineering, material honesty, and deep MTB culture. Their first model — a steel-framed, high-pivot, integrated-battery e-MTB — represents a unique convergence of innovation and heritage. ABUMS is not for everyone. It is for those who believe that riding is not just a sport, but a way of seeing the world.

Technology / Why Steel

Why Steel? Because Ride Feel Matters. In the rush to shave grams and win market share, the industry forgot something important: how a bike feels.

Steel is alive. It flexes. It absorbs. It tells the terrain’s story without screaming. Unlike carbon or aluminum, steel has a natural damping quality that filters trail chatter while maintaining a direct connection between rider and ground. It lasts longer, rides deeper, and ages with grace.

At ABUMS, steel isn’t a compromise.
It’s our starting point.
It’s the soul of the bike.

Suspension Philosophy

The High Pivot Advantage:
Our custom-developed high pivot suspension system is the result of years of riding, testing, and tuning. It allows the rear axle to move backward through the travel, closely following the terrain. This reduces pedal kickback, increases traction, and improves performance both up and down the trail.

The result? A bike that climbs like a machine and descends like a dream. More speed, more control, more flow.

Makers Page / Founders

Engineered by Riders. Built by Hand.
We’re not a tech startup. We’re not an e-commerce brand. We’re four guys who’ve spent most of our adult lives on two wheels — three mechanical engineers and one industrial designer with a shared obsession for mountain biking.

We’ve broken frames. We’ve crossed continents. We’ve raced, crashed, and rebuilt. ABUMS is the product of all of it.

This is not a business idea.
It’s a life idea.
