Our take
Power assist comes in a few shapes, and the Empulse R90 from Sunrise Medical is the under-the-seat kind. It attaches under most compatible rigid and folding manual wheelchairs with a V-Lock mount, which is why our notes call it a close alternative to SmartDrive-style assist. What stands out is that the drive wheel can lift up for zero rolling resistance when assist is off. A wireless Control Box sets speed and assist, removable batteries are available, and a long-range option is listed. Check compatibility and battery choices with Sunrise Medical. It is a pointer to the manufacturer, not an Equipment Library item.
Who it may help: Manual wheelchair users looking at power assist and weighing options.
