Abstract: A bicycle can include a forward frame triangle that can include a top tube, a bottom tube, a bottom bracket, a structural seat tube, a compliant seat tube, and a pair of seat stays. The top tube can have a first end connected to a head tube and a second end. The bottom tube can have a first end connected to the head tube. The bottom bracket can be connected to the bottom tube. The structural seat tube can be connected to the bottom bracket and the top tube. The compliant seat tube can extend in an upward direction from the bottom bracket to the top tube and within the structural seat tube. The compliant seat tube can be coupled to the forward frame triangle such that the compliant seat post can bend within the structural seat tube.

Abstract: A bicycle frame includes a tube with a hollow portion. The tube has an opening that provides access to the hollow portion, and the tube also includes one or more recessed flanges adjacent to the opening. The bicycle frame also includes a cover holder configured to mount to the one or more recessed flanges adjacent to the opening in the tube. The bicycle frame further includes an in-tube storage cover that mounts to the cover holder such that at least a portion of an exterior surface of the in-tube storage cover is flush with an outer surface of the tube. The in-tube storage cover includes a lever mounted on the exterior surface of the in-tube storage cover.

Abstract: A bicycle frame assembly that includes an upper frame member and a lower frame member that each extend between a head tube and a dropout. A seat tube extends between the upper frame member and the lower frame member. The seat tube is preferably connected to a bottom bracket of the lower frame member and is connected by a pivot to the upper frame member so that the seat tube can deflect from a rest position without altering an orientation of a top tube to a bottom tube of the upper and lower frame members, respectively.
