​​HOW IT STARTED,In January 1998, I (David Heim) founded The Wheelchair Recycler Inc. http://www.wheelchairrecycling.com/  in Marlborough, Massachusetts.

 THE 4X4 WHEELCHAIR, Since 98 my goal was to get back the freedom of the outdoors. Not even being close to afford the "off road chairs" on the market I had to build my own. By using standard power chairs. I always was able to go to most places  I wanted,,, most but not all. Always the inventor I never stopped thinking of a better way. 
In 2010 is when I designed the first 4x4 chain drive wheelchair. Still following original intent by using pre-owned standard power wheelchair motors and electronics. We now build the most affordable and most powerful 4x4 wheelchair available today.
