Whether you have a rigid frame or a folding wheelchair, the FreeWheel is your ticket to freedom, independence and increased mobility.With the FreeWheel your wheelchair casters are lifted off the ground, turning your chair into a 3-wheeler, so you simply roll over any obstacle: curbs, dirt trails, grass, gravel, snow, and sand. No more wasting energy and slowing down to pop a wheelie.You no longer need to spend time looking at the ground, worrying about every bump, stick or rock, or wasting energy wheeling over grass. With the FreeWheel you can look at the world around you and experience life to the fullest.Folding Wheelchair, no problem.The ADAPTOR for Folding Wheelchairs securely clamps on to the horizontal side tubing of your chair. Once set up for the individual chair, it comes on and off in seconds, making it easy to use. A standard FreeWheel attaches to the “hitch” out front instead of a wheelchairs footrest.
