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.

Among other things, a compliant element is configured to attach a seat of a device on which a user pedals to a frame of the device. The compliant element has a stiffness that is small enough to permit substantially unimpeded rocking of the seat relative to the frame in a plane in which the spine and pelvic bone of the user lie when the user is on the seat, and is large enough to maintain the seat in a substantially horizontal plane when the user is not on the seat.

A shell for a bicycle saddle has a groove opened through top and bottom surfaces thereof, a narrow anterior portion having a front edge, and a wide posterior portion having a rear edge and divided by an imaginary longitudinal axis passing through the front and rear edges and the groove into left and right regions where two sockets are located, respectively. The groove has a longitudinal section extending along the axis, and a transverse section extending from a rear end of the longitudinal section to the left and right regions so as to form two elastic wings adjacent to the groove. Each socket has a connecting sheet and an insertion block and extends from rear and lateral edges of the wide posterior portion to a position under the bottom surface to form a space therebetween. As a result, the shell has great elasticity and structural strength.

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.

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.

The disclosed physical exercise apparatus (2) comprises a frame (2′) equipped with a crankset and a saddle (26), the saddle itself comprising a chassis (262) fastened to the frame, two saddle parts (266) and articulation members (267, 268) for articulating each saddle part relative to the frame around a pitch axis (A26), about a roll axis (B26) and about a yaw axis (L26). This apparatus (2) also comprises sensors (30, 50) for detecting a pitch movement (T), a roll movement (R), and a yaw movement (L) of each saddle part respectively about the pitch, roll, and yaw axes, these movements resulting from pedaling made by a user. At least one calculation unit (40) is configured to determine, from output signals (S.sub.30, S.sub.50) of the sensors, angular amplitudes (α, β, γ) of the pitch (T), roll (R), and yaw (L) movements. At least one screen (29) is provided in order to display, depending on the angular amplitudes determined by the calculation unit (40), the position on each saddle part of a bearing point (P.sub.G, P.sub.D) of an ischium of a user in the process of pedaling.

Provided is a thin collapsible two-wheeled vehicle including: a pair of left and right mounting members provided to the main body frame to mount the rear wheel; wherein the pair of mounting members are each provided with a through hole penetrating each of the pair of mounting members respectively in left and right directions of the mounting members; the main body frame has a storage room therein, the storage room capable of storing the front wheel, the rear wheel, the saddle, and the handle; the rear wheel has an axle capable of moving within the through hole between a first mounting position and second mounting position; the rear wheel protrudes from the main body frame when the axle is mounted at the first mounting position, and the rear wheel is stored in the main body frame when the axle is mounted at the second mounting position.

A multi-degree-of-freedom riding saddle includes a support portion connected to a bicycle frame. A mechanical linkage may connect a first and a second seat plate to the support portion, such that the first and second seat plates each define a floating link of the mechanical linkage. A respective first connecting rod is coupled to a front end of each seat plate, and a respective second connecting rod is coupled to a rear end of each seat plate. A first swing cross rod connects the first connecting rods such that a lowering of a front end of one of the seat plates causes a front end of the other seat plate to rise. A second swing cross rod connects the second connecting rods such that a lowering of a rear end of one of the seat plates causes a rear end of the other seat plate to rise.
