Feature Tour

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.

Offset Axle Plate

The Catalyst 4 series axle is mounted less than 1/2" forward to traditional axle positions. 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.

Spoke

Ki standard spoke uses 30 radial spokes to provide a stiff and durable wheel.

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”.
