Hypershell X Ultra S Exoskeleton Review: AI-Driven Assistance Redefines Wearable Robotics

WIRED reviewed the Hypershell X Ultra S, the flagship model of Hypershell's new X Series exoskeletons, launched at CES 2026. The X Ultra S features a new AI-based control system called HyperIntuition, which processes movement continuously and adjusts torque in real time, achieving a claimed response time of 0.31 seconds and 97.5% human-machine synchronization. Made from carbon fiber and titanium alloy, it weighs 5.5 pounds, has a dual-battery setup with an 18-mile range, a 1,000-watt motor delivering 22 Nm of torque, and a max assisted pace of 15.5 mph. It offers 12 assist modes. The reviewer found the X Ultra S significantly more intuitive than previous models, with power delivery that adapts to terrain and pace, but noted it still feels unnatural and is heavy. Battery life is a limitation, with real-world range much shorter than claimed. The reviewer questioned the target audience, noting that outdoor participation among seniors increased 7.4% year-on-year in the US in 2025, suggesting an untapped market. Despite misgivings, the X Ultra S is deemed the best exoskeleton available, with lab tests showing heart rate reductions of 42.7% cycling and 22.3% incline walking, and leg muscle activity reduction up to 63.7%.
