Zusammenfassung:	A bicycle seatpost assembly comprises a first tube, a second tube, and a positioning structure to relatively position the first tube and the second tube. The positioning structure is mounted to at least one of the first tube and the second tube and is configured to change a state of the bicycle seatpost assembly among a first adjustable state in which the second tube is retracted or extended relative to the first tube at a first speed in response to a reference force applied to the second tube, and a second adjustable state in which the second tube is retracted or extended relative to the first tube at a second speed in response to the reference force applied to the second tube. The second speed is lower than the first speed.
