A bicycle assembly comprises a saddle adjustment assembly, the saddle adjustment assembly comprising an adjustable height saddle post, the adjustable height saddle post comprising first and second slidably coupled supports; a saddle post locking mechanism that selectively restricts sliding of the second support relative to the first support; and a saddle angle adjustment mechanism configured to couple to a bicycle saddle to enable rotation of the bicycle saddle between a first predetermined position and a second predetermined position, wherein, when the saddle post locking mechanism is in an unlocked configuration, the saddle angle adjustment mechanism enables rotation of the bicycle saddle between the first and second predetermined positions, and wherein, when the saddle post locking mechanism is in a locked configuration, the saddle angle adjustment mechanism maintains the bicycle saddle in one of the first and second predetermined positions.
