When the saddle body is moved in the front-rear extension direction, the slidable plate is constrained by the securing assembly from detaching from the bottom board in an upward/downward direction while allowing the pair of parallel channels of the slidable plate to move relative to the plurality of fixing pins in the front-rear extension direction to have the slidable plate together with the saddle body moving relative to the bottom board in the front-rear extension direction. ## Claims ### Claim 1 A forward and backward slidable saddle assembly (100) for a bike, comprising: a bottom board (3) adapted to be mounted on a carrier (1) of the bike; a slidable plate (4) slidably mounted on the bottom board (3), formed with a pair of parallel channels (41) spaced from each other by a distance, the pair of parallel channels (41) extending in a front-rear extension direction (M1); a securing assembly (5), including: a plurality of screw rods (51), which extends, in a direction from a lower side toward an upper side, through the pair of parallel channels (41) of the slidable plate (4) to have top free ends (52) of the plurality of screw rods (51) projecting out for a height; and a plurality of fixing pins (53) respectively seated in the parallel channels (41) and fastenable to the top free ends (52) of the plurality of screw rods (51); and a saddle body (6) mounted on the slidable plate (4); wherein when the saddle body (6) is moved by a user in the front-rear extension direction (M1), the slidable plate (4) is constrained by the securing assembly (5) from detaching from the bottom board (3) in an upward/downward direction while allowing the pair of parallel channels (41) of the slidable plate (4) to move relative to the plurality of fixing pins (53) in the front-rear extension direction (M1) to have the slidable plate (4) together with the saddle body (6) moving relative to the bottom board (3) in the front-rear extension direction (M1). ### Claim 2 (depends on 1) The forward and backward slidable saddle assembly according to claim 1, wherein each channel (41) of the pair of parallel channels (41) is formed with a top arc surface (411) and an opening slit (412) communicating between the top arc surface (411) and a bottom surface of the slidable plate (4). ### Claim 3 (depends on 2) The forward and backward slidable saddle assembly according to claim 2, wherein: each of the plurality of fixing pins (53) is a cylindrical fixing pin with a cylindrical surface, which is seated on the top arc surface (411) of a respective one of the parallel channels (41) in a manner of being slidable in a longitudinal direction of the fixing pin (53), a vertical threaded hole (54) being formed in the cylindrical surface of each of the cylindrical fixing pins (53); and the plurality of screw rods (51) penetrate through pre-formed apertures of the bottom board (3) and the opening slits (412) of the pair of parallel channels (41) to respectively screw into and fasten to the vertical threaded holes (54) of the plurality of fixing pins (53). ### Claim 4 (depends on 1) The forward and backward slidable saddle assembly according to claim 1, wherein the bike is one of an electrically-assisted bicycle, an electrically-assisted cargo-carrying bicycle, an electrically-assisted carrier, an electrical motorcycle, a cargo-carrying bicycle, a bicycle, and an exercise bike. ### Claim 5 (depends on 1) The forward and backward slidable saddle assembly according to claim 1, further comprising a carrier plate (2), the bottom board (3) being mounted by means of the carrier plate (2) to the carrier (1) of the bike. ### Claim 6 (depends on 5) The forward and backward slidable saddle assembly according to claim 5, wherein the bottom board (3) further comprises at least one locking mechanism (31, 32), and the bottom board (3) is securely fastened by the at least one locking mechanism (31, 32) to a counterpart buckling portion (22, 23) of the carrier plate (2). ### Claim 7 (depends on 6) The forward and backward slidable saddle assembly according to claim 6, wherein the locking mechanism (31, 32) comprises an operable button (311) and an elastic element (312), the operable button (311) being set in buckling engagement with the counterpart buckling portion (22, 23) of the carrier plate (2) by a spring force of the elastic element (312).
