Ki Mobility Catalyst 5Ti
The Catalyst 5Ti is a folding ultralight titanium wheelchair. You choose every part, and we check it against Ki Mobility's rules.
A folding chair in titanium, built to your measurements
The Catalyst 5Ti is Ki Mobility's folding wheelchair with a Ti3Al/2.5V titanium frame. Ki Mobility gives a 10.8 lb. transport weight at 16" x 16". The universal axle plate sets the seat heights in 1/2" steps and moves the center of gravity over a 3" range.
Choose the frame, seat size, rear wheels, casters and seat heights, footrest, back, wheel locks, armrests, accessories and color. Each choice is checked against the Catalyst 5Ti order form as you build.
What stands out
Titanium frame
Ki Mobility builds the frame from Ti3Al/2.5V titanium alloy and says it has twice the strength to weight ratio of 6061 aluminum and resists scratches and corrosion.
Titanium cross braces
An option that takes about 1/2 lb. more off the frame, for the 14" to 20" seat widths.
Universal axle plate
Sets the rear seat height in 1/2" steps and moves the center of gravity over a 3" range.
Heavy duty frame
The heavy duty frame raises the user weight capacity from 300 lbs. to 350 lbs.
One arm drive
One arm drive puts both handrims on one side, with its own spoke wheels on quick release axles.
Color accents
The titanium frame is left bare. Color comes from the accent package on the forks and axle plates and from colored mag wheels.
The Hieline Insight
The Catalyst 5Ti suits a full time manual wheelchair user who lifts a folding chair into a car often and wants titanium, up to 300 lbs., or 350 lbs. with the heavy duty frame. Choose it over the aluminum Catalyst 5 if the lighter frame and a titanium ride are worth the higher price, and choose the Catalyst 5 if you need the depth adjustable or reclining back or a painted frame. Take your hip width, seat depth, lower leg length and back height before you start, since Ki Mobility fixes every size when it builds the chair. Choose your rear wheels and casters before the seat heights, because they set the heights the page offers. Ki Mobility builds the chair to order, so it cannot be returned once it is made.

Common questions
Measure seated on a firm surface. Hip width sets the seat width, the back of the hip to the back of the knee sets the seat depth, the back of the knee to the floor in shoes sets the seat to footrest length, and the seat to the shoulder blades sets the back height. The measuring guide on this page shows each one.
300 lbs. With the heavy duty frame it carries 350 lbs. The heavy duty frame needs 5" or larger casters and is not sold with the transit system, the performance caster housing, Frog Legs forks, camber, swing-in anti-tips or fold down push handles.
Ki Mobility gives a transport weight of 10.8 lbs. at 16" x 16", with 5" x 1" poly casters and swing away arm receivers, without the footrest and rear wheels, and a standard weight of 18.8 lbs.
The frame is titanium instead of 7000 series aluminum, about 2 lbs. lighter in transport weight, and it is not painted. The Catalyst 5Ti does not offer the depth adjustable or reclining backs, front mount hangers, the super low front frame or swing away armrests with side guards, and its front seat height starts at 15".
No. Ki Mobility does not paint the titanium frame. The color accent package colors the forks and axle plates, and the colored mag wheels come in 21 colors.
No. The photographs show a cushion, which is sold separately.
Ki Mobility sells the Twist power assist from Klaxon as an add-on on its order form. We do not offer it on this page yet. The e-motion ready option, which installs the adaption kit for an Alber e-motion, is offered here.
Ki Mobility warrants the frame, cross braces, hangers and quick release axles of its Catalyst chairs against defects for the life of the original purchaser, with an expected frame life of five years. All other parts are covered for one year from the first purchase. Upholstery, tires, tubes, armrest pads, armrests and push handle grips are wear items and are not covered.
No. The Catalyst 5Ti is built to order to one user's sizes, so it cannot be returned. Ki Mobility's warranty covers defects.
No. You can order a Catalyst 5Ti from Hieline without a prescription.

Yes. Your progress saves automatically in your browser as you go, so you can step away and pick up where you left off on the same device.
Every combination is checked against Ki Mobility's own compatibility rules as you build. An option that does not fit your other choices is greyed out with the reason printed on it, and the build cannot be added to the cart while a conflict is open.
