Adjustable, Affordable, Better by Design.

Introducing the Catalyst 4E, raising the bar in both performance and quality.

Catalyst... the ride you expect, the brand you depend on.

There is a Catalyst Difference


Lightest in Class

Utilizing high-quality materials and innovative design Catalyst 4E is the lightest folding frame in the category, with an unprecedented 13.3 lbs transport weight! The lighter weight makes it easier for caregivers and clients without sacrificing quality or durability.

Best-In-Class Performance

Staying true to the Catalyst design and quality standards, Catalyst 4E uses the Dual-Cross Brace design that brings best-in-class rigidity and performance to the category. Integrated within the Dual-Cross Brace is the patented, exclusive Catalyst Power X-Hinge that makes folding and unfolding so easy! The combination results in a better, easier experience for clients and caregivers.

Quick and Infinite Adjustability

Make setup easier and quicker than ever with the new one-tool, anti-rotation leg length adjustment! Integrated into the reliable and familiar Catalyst hanger, the new adjustment design comes with the exclusive lifetime hanger warranty only available from Ki Mobility.

Do more with less!

Reach new heights with fewer part changes! The new single-frame design offers 5.5" of front seat height range by caster size, which is 1.5" more than the competitive designs. In combination with a new ultra-low caster housing, Catalyst 4E provides maximum adjustability over competitive designs. (12.5" - 21" | 31.8 cm - 53.3 cm)

Maximum Adjustability for Optimized Fit

Center of gravity adjustment and ride performance go hand in hand. The adjustable vertical axle plate gives you 2" (5.08 cm) of the center of gravity adjustment in 1/2" (1.27 cm) increments and 5" (12.7 cm) of rear seat height adjustment over seven positions. Find your fit, ease your propulsion and optimize the ride youve come to expect with Catalyst.

Quality and Durability you know and trust

Universal parts across the Ki product families, especially Catalyst, means increased efficiency and less complexity in setup and service. 15 years of proven performance and reliability give you peace of mind from the brand you can depend on.

Simple and Easy

Adjustments are easier and more intuitive with the new Angle Adjustable Backrest design! Two pivot point locations and angle presets mean you can order Catalyst set up to deliver right out of the box.

300 lbs Standard Weight Capacity

The only product in its class to offer a 300 lbs standard weight capacity! A heavy-duty option is also available. When quality and durability are important, you choose Catalyst.

Better Wheels Matter

Maxx, the standard spoke wheel that offers performance and style without a high price tag. With eighteen radial spokes and a high flange hub, the result is increased rigidity for a more responsive, better-performing ride. The heightened level of responsiveness combined with a lightweight design gives the rider the most from every push.
