CATALYST 5Vx by Ki Mobility
The Catalyst 5Vx has been redesigned from the logo to the frame, with a modern, minimalist approach. Enhanced designs let you optimize your ride!
 |
The Catalyst 5Vx is Ki Mobility’s Catalyst 5 with a newly designed axle plate and an adjustable camber tube. The Catalyst 5Vx is made from the ultra-light, high-strength 7000 series aluminum. This alloy dampens vibrations to provide a smoother and more comfortable ride. You also have the option to upgrade the frame or cross brace to titanium. Ki Mobility’s uniquely designed cross brace provides the feel of a rigid frame wheelchair with the convenience of a folding frame. 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.
