Ki Mobility Catalyst 4C Folding Manual Ultralight Weight Wheelchair

Ki Mobility Catalyst 4C Folding Manual Ultralight Weight Wheelchair

Short Description

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

The Catalyst Difference:

Catalyst 4 & 4C both 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.

While every model in the Catalyst family has a different axle plate with adjustment capabilities unique to each, they all take advantage of the same innovative design features that set them apart from other frames in the market. From the patented frame design constructed from 7000 series aluminum to the dual interlocking cross braces with a power x-hinge, there truly is a "Catalyst Difference".

Please call us at 833-207-3433 so we can help you configure your wheelchair to fit you!
The price shown is for the base model only. The image shows some options not included in the base price.

The Catalyst 4C has all the features of the Catalyst 4 but many more seat widths/depths are available  plus a better cross brace to work seamlessly with seating systems and positioning aids

Offset Axle Plate:

The Catalyst 4 series axle is mounted 1 1/2" forward to traditional axle positions. This small change can improve efficiency significantly. The simple axle plate design offers vertical adjustments of the axle in five positions. It can also be reversed to gain greater rearward stability.

Front Frame Styles:

Catalyst 4 & 4C offer the option of a swing-away front end featuring our patented footrests or 70° or 80° fixed frames. The swing-away hangers come in 4 bends (60°, 70°, 80° & 90°) are light and easy to use and so strong we offer a lifetime warranty.

Maxx Spoke:

Maxx is our new spoke wheel that offers performance and style without a high price tag. It features eighteen radial spokes and a high flange hub that result in increased rigidity for a more responsive, better-performing wheel. The heightened level of responsiveness combined with a lightweight design gives the rider the most from every push. Constructed with a 6061 series aluminum rim and straight steel spokes with a durable black satin finish for a look and feel that is anything but standard.

Maxx Mag:

Exclusive to Ki, the magnesium Maxx Mag wheel creates a sleek, modernized look while providing greater stiffness and lower weight than classic nylon composite mag wheels.

Maxx Mag wheels are available in 20”, 22”, and 24”.
