A bicycle assembly comprising a saddle adjustment assembly (42200, 43200) the saddle adjustment assembly (42200, 43200) comprising: an adjustable height saddle post, the adjustable height saddle post comprising a first support and a second support, the second support slidably movable relative to the first support between at least a raised position and a lowered position, the first support configured to attach to a bicycle frame; an actuating member (4220, 4320) movably coupled to the second support; a first lead screw (4255, 4355) coupled to the actuating member (4220, 4320) such that the first lead screw (4255, 4355) causes translation of the actuating member (4220, 4320) relative to the second support when the first lead screw (4255, 4355) rotates relative to the actuating member (4220, 4320); a saddle support arm configured to couple to a bicycle saddle such that the saddle is fixed with respect to the saddle support arm, the saddle support arm rotatably coupled to the second support at a pivot that is fixed with respect to the second support and the saddle support arm being rotatably coupled to the actuating member (4220, 4320) such that translation of the actuating member (4220, 4320) with respect to the second support causes the saddle support arm to rotate about the pivot and with respect to the second support; a second lead screw (4254, 4354) coupled to or formed as part of the first lead screw (4255, 4355); and a lead screw engaging device (4256, 4356) that contacts a thread of the second lead screw (4254, 4354) to cause the second lead screw (4254, 4354) to rotate relative to the second support when the second support slides relative to the first support. an adjustable height saddle post, the adjustable height saddle post comprising a first support and a second support, the second support slidably movable relative to the first support between at least a raised position and a lowered position, the first support configured to attach to a bicycle frame; an actuating member (4220, 4320) movably coupled to the second support; a first lead screw (4255, 4355) coupled to the actuating member (4220, 4320) such that the first lead screw (4255, 4355) causes translation of the actuating member (4220, 4320) relative to the second support when the first lead screw (4255, 4355) rotates relative to the actuating member (4220, 4320); a saddle support arm configured to couple to a bicycle saddle such that the saddle is fixed with respect to the saddle support arm, the saddle support arm rotatably coupled to the second support at a pivot that is fixed with respect to the second support and the saddle support arm being rotatably coupled to the actuating member (4220, 4320) such that translation of the actuating member (4220, 4320) with respect to the second support causes the saddle support arm to rotate about the pivot and with respect to the second support; a second lead screw (4254, 4354) coupled to or formed as part of the first lead screw (4255, 4355); and a lead screw engaging device (4256, 4356) that contacts a thread of the second lead screw (4254, 4354) to cause the second lead screw (4254, 4354) to rotate relative to the second support when the second support slides relative to the first support.
