One of the best things that has happened in the wheelchair industry is the development of Power Assist technology. Power Assist attaches to the wheels a wheelchair or directly to the ground in order to propel the wheelchair along.
Pushing a manual wheelchair can put stress on shoulders and lead to serious issues in the future. The SmartDrive® is an award winning power assist that provides the push you need whenever you need a bit of assistance. 
It offers a range of controls and activity-tracking technology to deliver a seamless power assist experience that may reduce repetitive stress; and it's compatible with folding chairs. 
The quick-release mounting bar is a big feature.  Just pull back on the spring loaded flanges to quickly attach or remove the SmartDrive, and it can go all day without re-charging.
