A cover assembly for a vehicle bed includes track members, support members, a flexible cover, and a reversible motor. The support members are movably arranged on the track members such that (1) movement of a distal one of the support members in the opening or closing direction causes the distal support member to push or pull each of the other support members in a sequential manner in the opening or closing direction. A drive cable is engaged with a gear operatively connected to the motor in intermeshed relation such that (a) rotation of the gear by the motor in a first rotational direction pushes the cable in a distal direction to push the distal support member in the closing direction and (b) rotation of the gear in a second rotation direction pulls the cable in a proximal direction to pull the distal support member in the opening direction.
