The portable Freedom-Trax Powered Track Attachment for Manual Chairs features left- and right-side tracks plus twin front and rear anti-tip wheels for added security. The device is designed to be attachable without assistance with the user remaining in the chair. Having a reported operating range of 5 miles and a top speed of 3 mph, the tracks are driven by two 24-volt motors that run off a 24-volt lithium ion battery; steering is via joystick. Adjustable for wheel widths between 17 and 26 inches, the Freedom Trax is designed to be modifiable each time one updates his/her chair.
