[0002] Bicycling is becoming an increasingly popular form of recreation and transportation. Furthermore, it has become a very popular competitive sport for both amateurs and professionals. Whether used for recreation, transportation, or competition, the bicycle industry continues to improve the various components of bicycles. One bicycle component that has undergone extensive redesign is the bicycle seatpost assembly.

[0003] Currently, the flippable seat tubes on bicycles on the market basically do not have a lifting function, and the liftable seat tubes do not have a flippable function. This is because the lift tube with a flippable function is close to the space at one end of the saddle. Due to structural limitations, the lift tube cannot be installed with a handle. The lift stroke is adjusted only by the bicycle center tube and the tube clamp, which is inconvenient for the rider to operate.

[0004] Therefore, how to provide a reversible dropper seat tube that integrates reversing and lifting in a bicycle seat tube assembly is a technical problem that those skilled in the art urgently need to solve. Utility Model Content

[0005] The main technical problem solved by the utility model is to provide a reversible dropper seat post, the upper portion of which is connected to a reversing mechanism via a connecting seat, and the opening and closing of the reversing mechanism and the lifting mechanism are controlled by a reversing wrench and a limit rod in cooperation. At the same time, a handle for controlling the lifting of the dropper is cleverly arranged on the opposite side of the reversing wrench, so that the reversing wrench and the handle do not interfere with each other, thereby solving the problem that due to structural limitations of the dropper seat post, a handle cannot be installed, and the lifting stroke is adjusted only by the bicycle center tube and a tube clamp, which is inconvenient for the rider to operate.
