An apparatus that is convertible between walker and a wheelchair has one pair of wheels that are continually engaged with the ground and a second pair of wheels that are movable from a first position out of engagement or disengaged with the ground, in which the apparatus is used as a walker, to a second position into engagement with the ground, in which the apparatus is used as a wheelchair. The movable wheels are controllable by the operator through the use of handle members connected such wheels. The handle members rotate the wheels into and out of engagement with the ground along a path that is at an angle from the vertical, thereby assuring disengagement of the wheels from the ground.
