Attaching the ZX-1 is simple. Just back your manual chair between the unit’s tubular armrests and press the “chair mount button” on the joystick. This engages a clamshell-like tube that robotically clamps around the chair’s camber tube (for folding chairs, the clamp goes around a ZX-1 add-on swing-away/quick-release camber tube) and lifts the rear wheels slightly off the ground.

The ZX-1 weighs 82 pounds with standard batteries and 75 pounds with Lithium batteries. Quick release armrests make it easy for strong friends to load the compact unit into the trunk of a car or for airline employees to load onto a plane. However, for air-tr
