Ki, Karmen, Drive, and Everest & Jennings wheelchairs.


Ki Mobility Ki Mobility started small, in size and scope, determined to design a high quality lightweight folding wheelchair that responds like a rigid. The Catalyst lines innovative design concepts breathed new life back into the folding wheelchair market. Three additional product lines in the pediatric, rigid and tilt-in-space categories have since launched with similar success.

Although Ki Mobility has experienced steady growth through the years, the high level of personalized service and a keen attention to detail remains. With an emphasis on remembering what is important and what it is that makes a difference in the industry we continue to move forward.



Innovative and Patented Frame Design Catalyst frames are constructed from 7000 series aluminum. A stronger and lighter vibration dampening alloy that contributes to the Catalysts superior durability and high quality construction. Whether you are in the market for a K0004 or K0005 you can always count on quality construction when choosing a Catalyst.

Dual Interlocking Cross Brace The Dual Interlocking Cross Brace design creates a frame that locks together to minimize the unwanted movement, or "front to back" racking, while redistributing loads onto components that can better manage forces. What this means to you is that no matter how much you use your Catalyst, the frame will remain as solid as it was the day you got it.



Between-The-Rails Design On typical above-the-rails designs all of the forces from the ground up, into the chair, and from the user down, through the chair, are transferred into the cross braces. In order to effectively deal with these loads other manufacturers design heavy cross-braces. The Catalyst's unique "between-the-rails" design transfers these loads from the cross brace to the vertical side frames. The geometry of the side frames allows them to support far greater loads.

Power X-Hinge The Catalyst's patented Power X-Hinge revolutionizes how the cross brace folds within the frame by acting as an extensible link that expands and contracts when the frame folds and unfolds. This patented device allows for a unique geometrical frame design that is more structurally sound than other designs while also making it much easier to fold and unfold, every single time.



Structural Integrity Other wheelchairs rely on the tension of the seat sling to solidify their frame when opened. However after a few months the upholstery experiences a natural stretching and your chair is "loosey goosey". The Power X-hinge eliminates the need for the seat sling to be a structural part of your frame. A Catalyst is solid even without upholstery. This ensures a more rigid and responsive ride.

Swing Away Front Hangers Enjoy the simplicity and strength of Catalyst's patented swing-away footrest hangers. The most intuitive hanger on the market allows you to attach and detach from any angle by simply pulling up or pushing down. It doesn't get any easier than this. The tapered engagement keeps the footrests snug and rattle free. Ki Mobility is the only manufacturer to offer a Lifetime Warranty** on the front hangers. Available in 60, 70, 80 and 90°.



Height Adjustable Armrest The tapered, noise free, no-rattle design of the height adjustable armrest produces a rock solid feel that is functional, light weight and easy to use. Like many of the options and accessories on Catalyst these were designed to be durable and user friendly. This is just one of many armrest options available. Visit the specific product pages to view all available armrest options.

Easy to transport, easy to push. The Catalyst 4 & 4C are the lightest most durable and energy efficient K0004 folders on the market today.

The Catalyst Difference The Catalyst 4 & 4C take advantage of all of the “Catalyst Difference” design features to allow you to fit, adjust and ride with confidence. A defining characteristic of each chair is its axle plate which we will highlight below.



Unmatched Performance. Ki Mobility's flagship product, the Catalyst 5 has since redefined the ultra-lightweight folding market by raising the bar in weight, performance, durability and functionality. Weighing in at 23lbs and constructed from ultra-lightweight 7000 series aluminum, the Catalyst 5 is arguably the best choice in high-performance folding wheelchairs. With our largest selection of options to help you customize and configure your chair, the Catalyst 5 makes daily life easier, no matter what the day brings.

Improved functions. The Ergo Lite 2 has basic functions of the Ergo Lite but is upgraded with 20" rear-wheel options and detachable footrest.

10kg is a fine line. It is said that the appropriate load for a woman to hand carry comfortably and with a lower risk of back injury is 10 kg. Karmen strives to make the caretakers’ life easier.

To make it even more portable, the Ergo Lite 2 weights 6 kg only after removing the rear wheels and footrest hangers.
