Overview
About the Edge 4

It pairs iLevel® seat elevation — 12 inches of lift, driveable at 4.5 mph while fully elevated — with the longest published range in the Edge line at up to 18.1 miles per charge. Four-pole motors and Q-Logic 3 electronics with Bluetooth make it the most capable base we configure for full-time power chair users.
