At Hypershell, we’ve always believed that human potential is greater than the limits of muscle and stamina. The X Ultra, our most advanced exoskeleton yet, is the embodiment of that belief. It’s not just a machine; it’s an extension of your body, a companion that helps you push boundaries, reach new heights, and explore the world in ways that once felt out of reach.

In this article, we’ll take you through everything that makes the X Ultra our flagship exoskeleton, from the engineering breakthroughs to the intelligent control system, from its rugged build to the real reactions it’s getting from media and KOLs around the globe.

Design & Build: Lightweight, Rugged, Ready

Weighing just 1.8 kg, it’s light enough to wear comfortably for extended periods. Its frame combines carbon fiber and aerospace-grade alloys, giving it strength without adding bulk. For real-world use, it’s also IP54-rated, offering protection against dust and water exposure, so you can focus on your adventure instead of worrying about your equipment. 

The harness and strap system are fully adjustable, ensuring a snug, secure fit. The battery is integrated into the lower back harness, and users can fine-tune the width and lockdown fit above the knees. Setup is straightforward, and once secured, the X Ultra moves seamlessly with your body.

Motors & AI MotionEngine: Smart Assistance

At the heart of the X Ultra are two M-One Ultra Motors, generating a combined 1,000 watts of power. This is paired with the AI MotionEngine Ultra, which uses more than a dozen sensors to monitor your movement in real time. The system adapts to how you walk, run, or climb, providing assistance precisely when and where you need it.

This combination of power and intelligence delivers real-world results. Users see up to a 39% reduction in physical exertion when cycling and a 20% reduction when walking, along with a 63% boost in hip flexor endurance—helping you climb, walk, or ride further with less fatigue.

Industry-Backed Credibility: World’s First SGS-Certified Exoskeleton

At Hypershell, we don’t just make bold claims—we get them independently validated. The X Ultra is the world’s first exoskeleton to undergo and pass third-party validation by SGS, a global leader in testing, inspection, and certification. This rigorous certification confirms the X Ultra’s assistive capabilities, including measurable reductions in physical exertion and significant improvements in endurance. By achieving this milestone, the X Ultra not only proves its performance through industry-standard testing but also sets a new benchmark for reliability and innovation in wearable robotics.

Intelligent Modes for Every Adventure

The X Ultra is more than raw power; it’s highly adaptable. Users can choose from multiple intelligent modes to suit different activities:

• All-new terrain modes—Cycling+, Running+, Snow, and Dune debut on the X Ultra, delivering specialized support for new frontiers. From pedaling with ease to powering through sand and snow, these fresh modes expand what’s possible.

• Eco Mode—gentle support with maximum battery efficiency.

• Hyper Mode—full-powered lift for steep climbs and challenging terrain.

• Transparency Mode—switch off assistance instantly to feel the difference.

• Fitness & ISO Modes—resistance-based training to build strength during everyday movement.

The modes allow users to tailor the X Ultra experience to their fitness, terrain, or activity level, making it equally valuable for casual users, athletes, and those seeking endurance support.

Battery Life & Endurance

Battery performance is critical for real-world use. The X Ultra offers:

• Up to 30 km in Eco Mode, with 800 meters in elevation at 50% power—nearly doubling the range capacity of previous models.
  

• Reduced but still meaningful range in Hyper Mode—approximately 6 km.
  

• Two batteries are included, so you can extend your journey without interruption.
  

This means the X Ultra can support long hikes, sports sessions, or active days without leaving you stranded.

User Experience: Simple, Intuitive, Empowering

The X Ultra is designed to feel seamless. Strapping it on takes only a few minutes, and the device immediately integrates with your movement. The more power you dial in, the more dramatic the assistance becomes, yet transitions are smooth and intuitive. Quick side-button controls allow mode changes on the go, while the Hypershell+ app provides granular adjustments, including torque distribution, haptic feedback, and assistance responsiveness. This design ensures that the X Ultra feels like a natural extension of your body, enabling effortless support while maintaining control and awareness of your own movement.

Real-World Impact: Media & User Endorsements

The Hypershell X Ultra is already redefining what’s possible for movement, adventure, and fitness, earning praise from both media and real-world users.

Adventures Made Accessible

At IFA 2025 in Berlin, Digital Trends’ Nirave Gondhia and Tom’s Guide’s Richard Bay both discovered how the X Ultra transforms physical challenges into achievable feats. 

Gondhia shared: “The Hypershell X Ultra helped me hike a hill that I couldn’t have hiked before… it gives me the confidence to live life on my terms and provides that necessary boost to keep me going further.”

Bay, tackling the iconic Teufelsberg hill, noted:  “After donning the Hypershell X Ultra at the bottom of the hill, I immediately felt confident I would make it to the top without exhausting myself… it was easy to get to grips with the different amounts of assistance.”

Even for those new to intense outdoor activity, the X Ultra transformed steep climbs and stairs into a comfortable, supported experience

The Electric Bike for Your Legs

Many reviewers remarked on the almost surreal sensation of having motorized assistance beneath your own limbs. 

Digital Trends likened the experience to:  “Think of this exoskeleton like an electric bicycle for your legs. You can pedal (walk) as normal, but the bike (exoskeleton) can kick in to provide electric power to help you speed up, travel further, or traverse complex terrain.”

Wareable captured the futuristic feeling: “There’s a truly bizarre sensation that comes from having your own legs powered by an external force… This is like having an e-bike for your legs.”

Meanwhile, Wired’s Adrienne So highlighted how natural the movement feels despite its advanced assistance: “The Hypershell X feels remarkably natural… At about 30 percent assistance, it can help you cover about 18 miles… It's also rated to -20°C, in case you need a little help climbing Everest or finishing your bike tour.”

Versatility in Action

The X Ultra isn’t just for hiking. Its intelligent assistance adapts seamlessly to cycling, running, and other activities. 

Forbes’ Andrew Williams noted, “More electric bike than motorbike… applying assistive power with each step, rather than attempting to force resting legs into movement.”

And Instagram user Antonio Santiago put it to the test on the football field: “Wearing the Hypershell X Ultra while playing football feels like flying. I felt stronger, it kept up with all my skills, and I actually think it increases my shot power as well.”

Across media coverage and firsthand experiences, one message is clear: the X Ultra empowers movement, extends endurance, and boosts confidence, enabling users to push past their limits—whether on a rugged hill, a city hike, a cycling route, or the sports field. Its intelligent, adaptable support makes what once seemed impossible feel entirely within reach.

Vision & Empowerment

At Hypershell, we believe movement should empower, not limit. The X Ultra removes physical barriers, giving you the confidence to climb higher, go further, and explore more than ever before.

As our CEO Kelvin Sun said, “Our goal with Hypershell X Ultra is to remove physical barriers and give people the confidence to say ‘yes’ to that mountain peak or that extra mile. It’s all about enabling personal achievement and ensuring the joy of adventure is open to everyone, regardless of their natural endurance.”

With intelligent, intuitive support, every step feels natural, enhancing your performance whether you’re hiking, cycling, playing sports, or staying active throughout the day.
