Wheelchair by Ki Mobility
The Catalyst 4 is the lightest, most durable, and energy-efficient K0004 folders on the market today!
The Catalyst line offers a Dual Interlocking Cross Brace. This design creates a frame that locks together so that it minimizes unwanted movement and maximizes the energy transferred in each of your pushes making your push as efficient as possible. The “Between-The-Rails” Seat Design has the seat frame tubing setting side-by-side rather than stacking them atop one another. Instead of the weight of the user resting on the cross brace, the weight is transferred to the side frames. This prevents having to use heavy cross braces which add weight to other manufacturer’s wheelchairs.
