Maxx Performance Spoke
Maxx Performance 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 give 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.
Mags Can Be High Performance Too
Ki Mobility proudly offers the ultra-sleek and lightweight X-Coretm mags. These wheels have far greater stiffness and rigidity than conventional mags while keeping the weight to only 1 lb. more than spokes. Now available in 20", 22" and 24".
Offset Axle Plate
The Catalyst 4 series 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.
Front Frame Styles - 4 & 4C
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 Difference - 4C
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.
