A saddle for bicycles has a body and a frame for supporting the body. The body has at least one slot at least partly extending in the rear portion of the body defining a right rear portion and a left rear portion of the saddle. The frame has a first branch and a second branch configured to be removably connected, respectively, to the right rear portion and to the left rear portion of the body passing from a first connecting configuration to a second connecting configuration, and vice versa. A bridge element that connects the first branch and the second branch is configured for removably coupling to the body to define a first distance and a second distance between the right rear portion and the left rear portion of the body. The first distance and the second distance correspond, respectively, to the first connecting configuration and the second configuration.

An adjustable-width saddle includes a frame having a forward end and a rearward end, the rearward end including a laterally extending bridge, and a one-piece shell. The one-piece shell includes a forward end connected to the forward end of the frame, and a split rearward end including a first rider support and a second rider support that are supported at least in part by the bridge. The rider supports are laterally separated from the second rider support by a lateral gap that is adjustable by flexure of the one-piece shell. A lower side of each rider support defines a first channel that receives the bridge. Fasteners extend through one or more slots formed through the bridge and engage the rider supports to fix the gap at a selected width.

A bicycle seat can include an attachment structure configured to be secured to a bicycle frame. The seat can also include a support frame, which can include right and left arms extending laterally out on opposite sides of a vertically-oriented medial plane of the bicycle seat. The seat can include walls, which can include a front wall and a rear wall that extend up and laterally out from the attachment structure to support the right and left arms. Right and left seat pads can be selectively securable to the right and left arms, and can be adjusted between different positions relative to each other. Each seat pad can include a main pad portion that is secured to the corresponding arm and is configured to provide upward support to a corresponding ischium (sometimes referred to as the sit bone) of the rider, and an elongate extension that can extend laterally out and forward beyond the main pad portion.

An adjustable seat assembly for a motorcycle has a seat pan and an adjustment mechanism. The seat pan includes a base portion and two pivoting portions that are pivotally connected to the base portion and are arranged laterally adjacent to one another on the base portion. The base portion has a fastening portion for fastening the seat assembly on the motorcycle. The adjustment mechanism is designed to pivot each of the two pivoting portions in relation to the base portion to adjust a lateral width of the seat assembly. A motorcycle with an adjustable seat assembly is also provided.

An angle adjustable bicycle saddle contains a seat post, a cushion, and a locking unit. The seat post includes an inwardly curved groove having multiple protrusions, and the seat post includes multiple troughs. The cushion includes a body and a cap. The body has a curved holder, an arcuate abutting projection, multiple engagement portions, and multiple through holes corresponding to the multiple troughs. The cap is covered on the curved holder of the body so that the curved holder has a hollow portion. The locking unit includes multiple fixing elements and multiple stepped nuts. A respective fixing element is inserted through a respective trough and a respective through hole. A first end of a respective fixing element is adjustably received in a respective trough, and a second end of the respective fixing element is accommodated in the hollow portion of the curved holder.

A bladder formed inside or positioned on a seat accounts for variations in personal anatomy with changes in the configurations of multiple chambers in the bladder and may also allow for changes to the constriction between the chambers in the bladder. The bladder forms a cushioning device that is used for seating applications which involve movement and continuously changes softness between the chambers by using the movement of the rider. Rider movement results in the interchange of pressures through variable-sized orifices between variable-displacement chambers. The number and size of the chambers can be varied according to a desired seating configuration. The orifice size can be changed with a variable constriction mechanism. Different fastening configurations can change the number and shape of the chambers. The cushioning device can be used in retrofitting existing seats and can be produced in new seats.
