Other Power Add-ons

Overview of Other Options

The following are other options that we considered instead of the Spinergy ZX-1. For various reasons, none of them fully fit our requirements. At the bottom is a comparison of all Power Add-ons listed, though some of it may be out-of-date.

MAX Mobility SmartDrive

SmartDrive 218The SmartDrive is a revolutionary new power assist device that will change your life. It can power you up steep hills and through thick carpet. It is intuitive to use, just push to go and brake to stop, its that simple. It will go for days on a single charge. Plug in and get out there!

The SmartDrive is surprisingly powerful. You can cruise up the steepest ramps and sidewalks. Even a thick padded hotel carpet is no problem. The SmartDrive has an anti-rollback feature that allows you to stop on a hill and then easily get going again.

Using the SmartDrive is natural. You push to go and brake to stop, it’s that simple. To go slow, push slow. To go fast, push fast. The SmartDrive is like a cruise control and you set the speed by the speed of your push. You turn using the pushrims, just like you would turn while going downhill.

The SmartDrive is lightweight and easy to install. The battery weighs 8 lbs and the motor weighs 11 lbs. The battery slips under the seat and the motor attaches to a hitch on back of the chair. The SmartDrive fits on almost any wheelchair, including folding chairs.

The SmartDrive is likely covered by your insurance, including Medicare, the VA, Workers Comp, and most private insurance. The insurance billing code is E0986. You will need to get a prescription for the SmartDrive from your doctor or therapist. You can print out this flyer and bring it in with you.

The SmartDrive reduces the number of repetitive pushes you do each day by taking over once you get going. It does not do all the work, so you are still getting plenty of exercise and activity. It just protects you from pushing too much.

Your insurance will not cover preventative medicine, so you need to qualify based on a condition that limits your independent mobility. There are many ways to qualify, including: pain in your shoulders or wrists, easily fatigued by pushing, difficulty pushing over carpet, or difficulty pushing up ramps or hills. It is up to you to protect yourself and ensure your shoulders stay healthy. Remember, you are your best advocate. Good luck!
