Features and Benefits

The ZX-1 is a revolutionary power add-on device that converts virtually any manual wheelchair into a joystick-powered manual chair. It is the only device on the market that requires no tools or assistance allowing the user to attach and detach autonomously. Seated in the manual wheelchair, the user simply backs over the ZX-1 and attaches to it by pressing a button on the joystick controller. Once attached, the ZX-1 is under full power thanks to two powerful 24 volt gear-driven electric motors that are commonly found on most large power chairs. It has the ability to operate on a variety of surfaces including gravel, hard pack, rocky terrain, thick grass, hills, etc. This quality sets it apart from other power assist devices that are on the market. The ZX-1 is as robust as most power chairs on the market, and tucks underneath the wheelchair preserving the user’s original overall width. The ZX-1 also only adds about 3” (7.6 cm.) in length. Due to its compact size and weight, the ZX-1 is ideal for airline travel and for use within homes and spaces with narrow doorways. Since the ZX-1 lifts up the wheelchair rear wheels slightly off the ground, the user can remove their wheels off of the chair while inside their homes in order to reduce the overall width of the wheelchair by 6” (15.2 cm.) making it much easier to navigate through doorways or around furniture. The ZX-1 has an adjustable range for seat widths from 14” to 20” (35.5 – 50.8 cm.). It can also adjust to different wheelchair wheel diameters of 24”, 25”, and 26” (540, 559, 590 mm.). The adjustability of the device simplifies orders for clinicians and dealers. Adjustability also allows for growth in the users’ wheelchair seat width, an important selling point to insurance providers because there is no need to purchase an entirely new device every time the wheelchair specs change. The ZX-1 includes an anti-tip safety system which provides stability and easy transitions over thresholds and curb cuts. The ZX-1 comes standard with two 12 Volt Lead Gel Mat Batteries that provide for a minimum range of 5 miles. Spinergy offers a Lithium Ion Battery option which extends the range to over 10 miles and reduces the overall weight of the device down to 75 lbs. (34 kg).
