Product Overview
The Karman S-Ergo ATX is a high-performance active wheelchair designed for bold daily use, featuring a 15.4-pound starting frame weight and a unique multi-geometrical extruded crossbar structure. Built by Karman Healthcare with 6061 T6 aircraft-grade aluminum and metallic AEGIS-treated high-gloss paint, every tube and weld has been precision-engineered for the highest possible strength-to-weight ratio. Available in diamond black and aspen white for users who won't compromise on performance or style.
Key Features
Product Highlights
The ATX frame is the result of years of R&D, with each component optimized so that larger users get the stability they need while smaller users aren't burdened by excess weight — a balance rarely achieved at this price point. The fully adjustable platform means seat height, back cane height and angle, front fork, footplate angle, and center of gravity can all be dialed in to a precise, personalized fit. Its folding cross-brace design makes the chair compact for storage while maintaining the rigidity of a rigid-frame chair during use.

Primary Use Cases
5 real-world scenarios for this product
🏙️ Active Daily Urban Use
Built for wheelchair users who live life at full speed. The ATX frame starts at just 15.4 lbs (frame) — light enough to maneuver aggressively through city streets, office corridors, and tight indoor spaces. The multi-geometric aluminum exoskeleton combines folding convenience with near-rigid performance, so every push translates directly into forward momentum.
🏃 Sports & Recreation
Whether it's basketball, tennis, racing, or recreational fitness, the ATX is engineered for physical activity. The low center of gravity and precise 4" front casters give you the responsiveness and stability needed for dynamic movement. Available in multiple seat dimension combinations (14"×15" to 18"×18") to match your exact body geometry and athletic posture.
🌳 Outdoor Navigation & Varied Terrain
The 24" rear wheels handle paved outdoor surfaces, curb cuts, and light terrain changes with confidence. The rigid-collapsing frame mechanism keeps the chair stable under aggressive use while still allowing you to fold and transport it quickly when needed. No wobble, no flex, no energy wasted.
✈️ Travel & Compact Transport
Folds compactly for car boots, overhead compartments, and travel storage. At a frame weight of 15.4 lbs (frame), it's manageable for one person to lift and store. The quick-release rear wheels make trunk loading even faster — pop them off, fold the frame, and you're in the car in under 30 seconds.
💼 Work, School & Social Participation
Designed for users who need a mobility solution that keeps pace with a full, engaged life — not just a medical device to move between rooms. The ergonomic S-shape seating keeps posture healthy during long hours at a desk, in a classroom, or at social events. Supports up to 265 lbs with a frame that's built to last through years of daily active use.
