Pulleys aren't that common on bicycles, pretty much only bikes with external gears have them. They're used in the rear derailer to let the chain change direction so that the derailer can take up the slack that comes from changing gears.
Some ladies/mixte frames use a pulley up by the seatpost to change the pull direction of the brake wire. Yet some bikes use a pulley to get the right pull direction for the front derailer.
