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.
The axle is mounted 1 ½” 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.
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.
The Catalyst 4 & 4C offers Ki Mobilitys full line of specially designed Ki spoke wheels with precision machined hubs and hard anodized handrims. Utilizing straight pull spokes this wheel promotes a stiffer and stronger wheel while the hard anodize handrim is resistant to scratching so they keep that “NEW” look longer. We also offer the full array of industry standard wheels and casters such as Spinergy, Natural Fit, Frog Legs and Topolino.
