A stroller comprising:

• a seat;
• a handle having at least one first mount disposed thereon;
• a main frame connected to the handle and the seat and having at least one second mount disposed on at least one side of the seat;
• and
• at least one cup holder module detachably mounted on at least one of the at least one first mount and the at least one second mount, the at least one first mount and the at least one second mount having an engaging groove formed thereon respectively, and the at least one cup holder module comprising:
• a cup holder;
• a mounting arm formed from the cup holder;
• and
• a first mounting latch disposed on the mounting arm and having a first button, a clamping base, and an elastic member, the first button being movably disposed on the mounting arm, the clamping base being connected to the first button and disposed in the mounting arm, the elastic member being disposed on the clamping base for providing a first elastic force to bias the clamping base toward a latched position to clamp the at least one of the at least one first mount and the at least one second mount cooperatively with the mounting arm when the mounting arm is mounted on the at least one of the at least one first mount and the at least one second mount and the first button is engaged with the engaging groove;
• wherein when the first button is pressed to overcome the first elastic force generated by the elastic member for moving the clamping base from the latched position to an unlatched position, the clamping base is separate from the at least one of the at least one first mount and the at least one second mount so as to make the mounting arm detachable from the at least one of the at least one first mount and the at least one second mount.
