Bicycle seatpost capable of mounting with bicycle accessory
A bicycle seatpost includes a seatpost body and a reinforcing member. The seatpost body has an opening through inner and outer surfaces thereof. The reinforcing member is fixed to the inner surface of the seatpost and has a part corresponding to the opening, such that an installation space is formed between the reinforcing member and the opening for installation of a bicycle accessory. As such, the bicycle seatpost of the present invention uses the opening to install the bicycle accessory (such as a lamp, rearview lens, rear bag, or bottle cage), and uses the reinforcing member to make the seatpost body maintain sufficient structural strength, such that the seatpost body will not weaken its structure due to the opening.
