Overview
Ki Mobility's whole 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. So 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 the wheelchair.
Even how the Catalyst 4C folds and unfolds is unique. A Power X-Hinge is an extending link from the frame to the cross brace that expands and contracts when the frame is opening or closing. Another benefit of the Power X-Hinge is how it improves the frame’s structural integrity. The extending link provides the frame’s strength and rigidity rather than the seat upholstery.
Not to be forgotten are Ki Mobility’s one of a kind legrests. The legrests can be mounted or removed from any angle. No need to rotate all the way or all the way out like those found on other wheelchairs.
What Makes This Different
The Catalyst 4C has all the features that separate you get from the Catalyst 4 but offers a much wider range of seat widths and depths as well as a cross brace that easily accommodates seating systems and positioning aids. A removable solid seat pan can be added for those needing a more supportive base for their cushion. As with the Catalyst 4, the 4C features the offset axle. The axle plate is mounted 1-1/2” forward to the axle position of similar wheelchairs from other manufacturers. By positioning the axle plate in this fashion, the Catalyst 4C can greatly improve your push efficiency. The design of the simple axle plate allows for easy vertical adjustments in 5 different positions. For those wanting or needing greater rearward stability, the axle plate can be reversed. You also get the rear wheel options of Ki’s own Maxx Performance Spoke which gives you a highly rigid and responsive ride that gives you the most roll for every push you give it. If you prefer mag wheels to spoke wheels, the Catalyst 4C also offers X-Core’s lightweight and stylish mag wheels. The X-Core mag wheels provide greater stiffness and a more rigid ride than traditional mag wheels.
Why We Like It
The Catalyst 4C offers a great range of options for an affordably priced lightweight wheelchair. The 4C can accommodate seat widths from 14” to 22” and seat depths from 14” to 20”. Seat heights are available from 13.5” to 21”. This means the Catalyst 4C can be a great wheelchair for everyone from a shorter user who propels with their feet to the taller user who prefers to push with their hands. A special cross brace is available to easily adapt to specialty seating. The 4C also can be built with a removable aluminum solid seat so complex seating can be provided while still permitting the wheelchair to fold for easy transport.The Catalyst 4C is a great option whether you need a basic lightweight wheelchair or a lightweight wheelchair capable of meeting unique body types or special needs.
Measuring Guide
View Detailed Measurement Guide
- Seat Depth1
- Measure from the most posterior point of the body to the inside of the knee, minus at least two inches. Some prefer more leg overhang to make room for their hand when lifting their leg.
- Back Height2
- Measured from the seat base to the top of the wheelchair back. Depends on how much upper back support is needed, and also affects freedom for the upper body to rotate.
- Rear Seat to Floor3
- Measurement from the ground to the rear seat edge. Relative to the front seat-to-floor dimension, this determines the rearward slope ("dump" or "squeeze") of the wheelchair seat.
- Hanger Angle4
- Determines how far the toes extend away from the body, measured from the horizontal. A tighter angle allows the wheelchair to turn around in less space. Depends in part on ability of the knee to bend towards the perpendicular.
- Seat Width5
- Determined by the widest point of the body from knee to hip, plus an inch to ensure room to move. Consider bulk of clothing, particularly a heavy winter coat, if relevant.
- Wheel Camber6
- Angle of the wheel relative to the vertical. More camber improves stability and agility, but also limits ability to pass through narrow spaces. A typical daily wheelchair uses three degrees of camber.
- Front Seat to Floor7
- Measure the leg from the back of the knee to the sole of the foot. Then subtract the thickness of the cushion when it is compressed. Next, add a minimum of two inches for footrest clearance. Do not add the footrest clearance if the wheelchair will be foot-propelled.
- Footrest Width8
- Measure from the inside of each legrest tubing the distance or desired distance between legrests.
- Center of Gravity9
- Measure from the front of the seat back post to the center of the rear axel.
- Seat to Footrest Length10
- Measure from the edge of the seat upholstery to the top rear of the footrest.
- Backrest Angle11
- Measure the the angle of the back post to the floor. Ninety degrees will be perpendicular to the floor, to approximate the angle from the back post to the seat, subtract two degrees from measurment for every .5" of dump.
