The device is generally provided from a first member and second member in a hinged coupling secured through a spring-loaded fastener for coupling to the seat post at a desired height. ## Claims ### Claim 1 A bicycle seat drop stopping device, comprising: a first member, a second member, each of the first member and the second member having an interior surface, an exterior surface, a first end and a second end, the second end of the first member and the second end of the second member hingedly couplable to each other; and a spring-loaded fastener comprising a compression spring having an interior and a screw within the interior, the spring-loaded fastener capable of providing an adjustable spring-force, the compression spring of the spring-loaded fastener is positioned between the first end of the first member and the first end of the second member, opposite the hingedly couplable second end of the first member and the second end of the second member; wherein the stopping device is configured for placement upon a bicycle seat post in a way that the stopper device restricts movement of the seat at a desired height between a highest point and a lowest point for generally stopping the seat from traveling to a lowest position. ### Claim 2 (depends on 1) The bicycle seat drop stopping device of claim 1, wherein the spring-loaded fastener is located at the first end of each of the two members and the two members are hinged coupled at the second end, to allow the two members to move from an open position to a fastened position. ### Claim 3 (depends on 2) The bicycle seat drop stopping device of claim 2, wherein the spring-loaded fastener secures the two members around the bicycle seat post in the fastened position. ### Claim 4 (depends on 3) The bicycle seat drop stopping device of claim 3, wherein the two members define a void, wherein the bicycle seat post is located within the void. ### Claim 5 (depends on 4) The bicycle seat drop stopping device of claim 4, wherein the spring-loaded fastener allows for the device to be adjusted around various sizes of seat posts. ### Claim 6 (depends on 1) The bicycle seat drop stopping device of claim 1, wherein the spring-loaded fastener, wherein the first end of the first member has a hole and the first end of the second member has a hole, wherein the spring loaded fastener is configured to couple to the first end of the first member and the second end of the second member and move the device from a first position to a second position. ### Claim 7 (depends on 1) The bicycle seat drop stopping device of claim 1, wherein the two members are arcuate in shape and mirror images of each other. ### Claim 8 (depends on 7) The bicycle seat drop stopping device of claim 7, wherein the two members are coupled together in a hinged assembly with the spring-loaded fastener positioned opposite the hingedly coupled second ends, wherein each of the interior surfaces define a void between the pair of members, the void configured to adjustably receive and secure various sizes of bicycle seat posts. ### Claim 9 (depends on 8) The bicycle seat drop stopping device of claim 8, wherein each of the interior surfaces further comprise a soft rubber lining. ### Claim 10 (depends on 1) The bicycle seat drop stopping device of claim 1, wherein the device is constructed from anodized aluminum. ### Claim 11 A bicycle seat drop stopper device configured for removable attachment to a bicycle seat post, the drop stopper device comprising: a first member, the first member having an interior surface, an exterior surface, a first end, and a second end; a second member, the second member having an interior surface, an exterior surface, a first end and a second end, the second member hingedly coupled at the second end with the second end of the first member, the first member and the second member coupling movable from an open position to a fastened position; and a spring-loaded fastener, the spring-loaded fastener at least comprising a compression spring having an interior and a screw within the interior, and the compression spring positioned between the first end of the first member and the first end of the second member, wherein the spring-loaded fastener connects the first member and the second member opposite the hingedly couplable second ends in the fastened position; wherein the spring-loaded fastener allows for the device to be adjusted around various sizes of seat posts. ### Claim 12 (depends on 11) The bicycle seat drop stopper device of claim 11, wherein each of the interior surfaces of the first member and the second member define a void between the pair of members, the void configured to receive and secure the bicycle seat post. ### Claim 13 (depends on 12) The bicycle seat drop stopper device of claim 12, wherein the first member and the second member are arcuate in shape and mirror images of each other. ### Claim 14 (depends on 13) The bicycle seat drop stopper device of claim 13, wherein each of the interior surfaces further comprise a soft rubber lining. ### Claim 15 (depends on 14) The bicycle seat drop stopper of claim 14, wherein the device is construed from anodized aluminum. ### Claim 16 (depends on 12) The bicycle seat drop stopper of claim 12, wherein the first end of the first member has a hole and the first end of the second member has a hole, wherein the spring loaded fastener is configured to couple to the first end of the first member and the second end of the second member.
