I claim the ornamental design for a bicycle seatpost, as shown and described.
FIG. 1 is a perspective view of a bicycle seatpost embodying the present invention.
FIG. 2 is a left side view of the design shown in FIG. 1.
FIG. 3 is a right side view of the design shown in FIG. 1.
FIG. 4 is a front view of the design shown in FIG. 1; and,
FIG. 5 is a rear view of the design shown in FIG. 1.
The portions of the seatpost shown in broken lines in FIGS. 1-5 form no part of the claimed design.
In the normal and intended use of the seat post, the top view is substantially obstructed by a bicycle seat mounted on the seatpost, and thus the top view is not a matter of ornamental concern.
In the normal and intended use of the seat post, the bottom view is substantially obstructed by a bicycle frame to which the seatpost is mounted, and thus the bottom view is not a matter of ornamental concern.
