If the user is tired of pushing him or herself by grabbing the two large wheels and moving them forward, he or she can try to con some unsuspecting dupe into grabbing hold of the two handles located just above the back of the wheelchair, and pushing the user around that way. The one who performs this action for the wheelchair user is usually either a friend, a nurse, an idiot, or some combination of all three. There has yet to be a form of manually operated wheelchair which is operated by pulling the user. These are referred to as rickshaws or something of that nature, and fall into a completely different jurisdiction, not covered in this entry. They would also be much more difficult to get through doorways, and it is unnecessary to create any item on the face of this reality more difficult to get through doorways than a wheelchair, so the concept is moot.
Some modern wheelchairs are battery operated.
These are known as battery-operated wheelchairs. Some also use the term self-propelled, but that suggests that the wheelchair does in fact have a sense of self. Battery-operated wheelchairs travel at a speed in excess of one mile every five weeks. In This Project Galactic Guide site owned by Alex McLintock .
