The present invention relates to a device for adjusting the height of a bicycle saddle, the device comprising a covering member and a cylinder head configured in an outer enclosure cylinder and having an inner enclosure cylinder installed in the cylinder head. The cylinder head has a control valve means configured therein to control oil fluid and has an oil covering configured therein to store oil fluid. A post head provided with a height control member and an air injection member is combined with a seat post, a saddle coupling means is configured above the post head, and a rod member including a piston is configured below the post head, thereby allowing the seat post to come into and out of the outer enclosure cylinder and allowing the rod member to come into and out of the inner enclosure cylinder. The inner enclosure cylinder and the height control member of the post head are coupled to each other by a connection line, and compressed fluid is stored in the outer enclosure cylinder and the seat post, thereby adjusting the lift of the seat post operated by the compressed fluid to a certain height depending on the length of the connection line. The covering member of the outer enclosure cylinder has a withdrawing means, which is provided with a withdrawing connection line, configured therein and is coupled to the control valve means by the withdrawing connection line to enable the oil fluid stored in the inner enclosure cylinder to come in and out while the control valve means is opened and closed by the withdrawal of the withdrawing connection line, thereby adjusting the height of the seat post by the compressed fluid and the oil fluid. Therefore, the height of a bicycle saddle can be adjusted accurately and conveniently with simple configuration.
