A conveyance seat includes a saddle-type seat on which an occupant sits to straddle and a seat height adjustment unit which is attached below the seat and is able to adjust a height position of the seat. The seat height adjustment unit includes a rotation link which rotates together with the seat with respect to a chassis to adjust a height position of the seat, an upper link support member that is provided between the seat and the rotation link and is used so that an upper end portion of the rotation link is attached thereto, a lower link support member that is provided between the rotation link and the chassis and is used so that a lower end portion of the rotation link is attached thereto, and a flexible cover member that covers the rotation link from the outside in a front to back direction of the seat and a width direction of the seat.

A bicycle seat accessory that includes an adjustable seat and a rear seat accessory to provide a seating surface for a user and a rider or passenger. The adjustable seat is movable between a first and second position and when in the second position, the seating surface of the seat substantially aligns with the seating surface of the rear seat accessory to form a substantially continuous seating surface. The frame of the bicycle includes an accessory shelf onto which the rear seat accessory can be mounted. Additionally, the frame includes one or more brackets to which footpeg accessories can be mounted to provide foot rests for the passenger of the bicycle while seated on the rear seat accessory.

A straddled vehicle includes a vehicle frame, a main seat, a tandem seat, an accommodation portion provided below the tandem seat, a seat lock mechanism attached to a bottom portion of the tandem seat, and a lock portion attached to the vehicle frame in a front portion of the accommodation portion. The seat lock mechanism includes: a key cylinder that has a main body having a key insertion hole, and an arm pivotable around the main body by a pivoting operation made by a key; and a hook member pivotable along with the pivoting of the arm. The hook member includes a first hook portion engageable with the arm, at least one second hook portion engageable with the lock portion, and a pivoting restriction portion configured to restrict the hook member from pivoting in a state where the key insertion hole does not have the key inserted therein.

A cargo-carrying wheeled vehicle comprising: at least a cargo hold chassis (10); at least a battery support chassis (30) configured to be operatively behind or operatively ahead or operatively underneath said cargo hold chassis (10); and at least a rider and pillion support chassis (20) configured to be operatively behind said battery support chassis (30) and operatively behind said cargo hold chassis (10), in that, said cargo hold chassis (10), said battery support chassis (30), and said rider and pillion support chassis (20) cooperate to maintain centre of gravity of said vehicle, after addition of cargo and rider and pillion, relatively lower (closer to ground) and substantially on or very near to the centerline of the wheelbase of this vehicle (between 10a and 12a).

A straddled vehicle includes a body frame, a seat, a battery case storing a battery and inertial measurement unit, a drive wheel. The battery case is provided such that its bottom portion protrudes toward the position between the rear suspension and the rear wheel. The inertial measurement unit is fixed to the bottom portion of the battery case at a position above the inertial measurement unit. The bottom portion of the battery case is located in a space other than a space in which the rear suspension and the drive wheel are positioned when the rear suspension is in a most contracted state due to absorbance of shock. At least the battery and the inertial measurement unit partially overlap each other in a plan view of the vehicle.

A saddled electric-powered vehicle is configured by including approximately rectangular parallelepiped batteries, a battery case in which the batteries are housed, battery-side terminals provided on bottom surfaces of the batteries, and case-side terminals engaged with the battery-side terminals. The battery case is arranged below a seat, and pressing holders that press the batteries housed in the battery case from above are provided while making a front and rear pair for each battery. The battery case is formed in a bottomed box shape with an upper side open. Each pressing holder is provided with a rubber portion brought into contact with an upper surface of each battery. The saddled electric-powered vehicle can enhance convenience by optimizing an arrangement and a housing structure of portable batteries.

A straddle-type electric vehicle includes two approximately rectangular parallelepiped batteries, a battery case in which the batteries are housed, battery-side terminals provided on bottom surfaces of the batteries, and case-side terminals engaged with the battery-side terminals. The two batteries are arranged next to each other in a vehicle width direction. An operation lever for connecting or separating the battery-side terminals and the case-side terminals to/from each other is provided. The operation lever is arranged in a middle in the vehicle width direction between the two batteries, and the battery-side terminals and the case-side terminals are arranged nearer outer sides in the vehicle width direction. A pair of front and rear link mechanisms for coupling the operation lever and the case-side terminals to each other is provided in front of and behind the battery case.

A fuel tank and a seat assembly including the fuel tank is provided. The seat assembly includes a fuel tank, a seat frame securable to the fuel tank, and optionally a rear panel that supports a rearward portion of the seat frame. The seat assembly may define a chamber between the fuel tank and the rear panel. The seat frame is removably secured to one or both of the rear panel and the fuel tank. The fuel tank and rear panel may define a v-shape capable of distributing the rider load.

According to one or more aspects of the present disclosure, a removable seat assembly is provided comprising a first mounting feature engageable with the tunnel of a snow vehicle, and optionally a second mounting feature engageable with the tunnel of the snow vehicle. The first mounting feature may automatically engage the tunnel upon engagement of the second mounting feature with the tunnel. The seat assembly may comprise a frame base, a riser defining a chamber therein positioned on the frame base, a seat back frame, and an arm rest secured to the frame base and the seat back frame.
