The revvll story: From Vision to Victory

In 2011, a chance encounter with a massive rope climbing machine at a local gym changed everything. It weighed 150 kg, came with a bench for seated pulls, and begged to be reimagined. Ignoring the bench, my friend and I experimented - pulling, pushing, and moving sideways. The freedom of movement and steady resistance across every motion were unlike anything I’d experienced. It hit me: what if I could shrink this beast into a 5 kg, portable powerhouse, like our aeroSling Pulley Suspension Trainer? The idea for the revvll was born - but turning it into reality took five relentless years.

Breaking the Mold

Traditional rope trainers were clunky and restrictive. I wanted portability without sacrificing performance. Standard friction-based resistance wouldn’t cut it - too jerky, too weak, or reliant on heavy counterweights. After digging deep, we landed on eddy currents: electric currents generating magnetic resistance. This breakthrough let us craft a compact, lightweight device with the high resistance I envisioned.

Stumbling Blocks

The first iteration, the original revvll ONE, was a handmade mess. Precision varied wildly - some units shone, others wouldn’t even spin. YouTubers pushed the limits too, sometimes slamming it into the ground mid-pull.

Then there was the rope. Textile ropes, common in battle ropes, crumbled under continuous stress. We tried gluing, melting, even screwing them together - nothing lasted. We’d rushed to market too soon, and while the concept won fans, the execution frustrated them.

Turning the Tide

We hit pause, retooled everything, and launched the revvll PRO. Handmade parts gave way to injection molding and precision metalwork, thanks to trusted manufacturing partners. The base unit toughened up, but the rope remained a weak link. A custom PVC hose sounded promising - until it snapped, some after mere hours. Customers who’d shelled out serious cash deserved better, and we couldn’t afford to fail them.

The Rope That Held

Back to square one, I scoured for a fix. A German company specializing in mechanical belts (think car fan belts) stepped up. After countless trials - tweaking materials, profiles, and structure - we nailed a rope that could take the punishment. It meant redesigning parts of the revvll PRO, but by 2016, we’d cracked it. Every unit now endures a brutal 40-hour test at max resistance before shipping. Since then, across thousands of units, the solutions have proved itself!

Made in Germany - Always

Every revvll is 100% built in Germany, a mark of quality we’ll never compromise. That’s why we warn against fakes. Dubious sites peddle lookalikes that mimic the revvll’s design but dodge its engineering. These copycats never solved the rope or durability issues we conquered - they break in days or weeks. Stick to authorized channels for the real deal.

A Promise Kept

From 2011 to 2016, we fought for this. We upgraded every sold unit, often at steep cost, because leaving customers hanging wasn’t an option. I personally repaired hundreds, learning from each worn part. That grind paid off. The revvll PRO became a global standout - tough, versatile, and trusted in gyms and homes alike.

Looking Back, Charging Ahead

This chapter closed in 2016, but the revvll’s story rolls on. Thanks to every customer who stuck with us through the early hiccups - your belief fueled this triumph. We improved the PRO a lot since then, added a new version of the revvll ONE to the lineup. Try the revvll ONE or PRO yourself and feel the difference a half-decade of grit delivers.

Sportive greetings,
