The invention relates to a collapsible vehicle (10), in particular a collapsible motor scooter, having a rear frame part bearing a seat unit (70) and at least one rear wheel (11) and a front frame part (61) bearing a steering unit (19) and at least one front wheel (11). According to the invention, the front frame part (61) and the rear frame part (60) are connected to one another via an acentric pivot joint (80) such that during collapsing of the vehicle (10), at least one frame part (60, 61) is pivotable such that the at least one front wheel (11) and the at least one rear wheel (11) are arranged adjacent to one another, in particular congruently adjacent to one another.

A straddle vehicle comprises an axle; an external member which is externally fittable to the axle; and a fastening member fastened to the axle to prevent disengagement of the external member. The axle includes an outer tube member to which the external member is externally fittable, and an inner shaft member which is inserted into the outer tube member and is longer in an axial direction of the axle than the outer tube member. The inner shaft member includes a shaft part which is internally fittable to the outer tube member, a male thread part formed in an outer peripheral surface of a first end portion of the shaft part, and a retaining part protruding radially outward from a second end portion of the shaft part, the retaining part being configured to retain an axial tension of the inner shaft member generated by fastening the fastening member to the axle.

A vehicle includes a main vehicle body, a suspended assembly that supports the main body of the vehicle, a suspension arrangement for connecting the suspended assembly to the main body of the vehicle, and a steering system for steering the suspended assembly. The suspended assembly assisting in providing directional control of the vehicle and stability in a lateral direction relative to a normal straight-ahead direction of travel for the vehicle. The steering system including a first steering arrangement that controls movement of the suspended assembly relative to the main vehicle body such that the suspended assembly pivots about a first steering axis. The steering system further including a second steering arrangement that controls movement of the suspended assembly relative to the main vehicle body such that the suspended assembly pivots about a second steering axis with the second steering axis being different than the first steering axis.

A vehicle has a vehicle frame, two front wheels, a rear wheel. An engine with at least one cylinder is mounted to the vehicle frame such that a cylinder plane extends generally longitudinally and vertically. At least a portion of the at least one cylinder is disposed forward of a front wheel plane. A transmission assembly disposed longitudinally rearward of the engine. A straddle seat is disposed at least in part longitudinally rearward of the assembly. The engine is entirely disposed between a center of the left footrest and a center of the right footrest in the lateral direction.

A saddle-type vehicle includes a vehicle body frame including a main frame extending obliquely rearward and downward from a head pipe, a down frame extending downward from the head pipe and supporting an engine, and a seat frame extending rearward from the main frame and supporting a riding seat, wherein a front wheel is supported by a front portion of the vehicle body frame via a front fork, and a rear wheel is supported by a rear portion of the vehicle body frame via a swing arm, and a vehicle height adjustment device provided below the seat frame to elastically support the seat frame and configured to adjust a height of the seat frame. The vehicle height adjustment device includes an actuator unit and a cushion unit. The actuator unit is disposed between the cushion unit and the engine.

A folding vehicle is adjustable between an unfolded position and a folded position. In the unfolded position, the wheels of the vehicle are in a leading and trailing relationship. In the folded position, the components of the folding vehicle have a minimal footprint allowing for compact storage. In the folded position, the wheels may be in a side-by-side relationship with the majority of the vehicle components positioned between the wheels.

The present invention discloses an installation structure for a wheel axle assembly and a wheel fork, a frame and a vehicle. The wheel axle assembly includes a wheel axle; a first bearing, a bush and a second wheel axle sleeved on the wheel axle successively; and a hub arranged on the outer rings of the first bearing and the second bearing, wherein the bush is used for spacing apart the first bearing and the second bearing axially a predetermined distance, and the hub is of a sleeve shape and an end thereof arranged on the first bearing expands the outer diameter to form a flange portion for fixing and installing a wheel; and the wheel fork includes a wheel fork body and a frame connection portion formed on an end of the wheel fork body and forming an L shape with the wheel fork body for connecting to a frame, and the wheel axle is fixed on the other end of the wheel fork body in a direction perpendicular to the rim center plane of the wheel.

A vehicle wheel axle assembly including: an axle extending along an axial axis having a first end and a second end axially opposed to the first end; a hub shell rotatable about the axle and about the axial axis; a frame element having a dropout for connection with the axle. The axle is a cantilevered axle with a first end removably connected to the dropout. The first end includes an axially outwardly facing first end face. The dropout includes an axially inward facing inboard face and an open slot to receive the axle adjacent the first end, with the open slot including an open entrance portion, a closed terminus region, slot sidewalls extending between the entrance portion and the terminus region. The axle is generally radially inwardly assembled to the open slot through the open entrance.

There is described a quick-release arrangement for mounting a bicycle wheel (2) to a hub of a bicycle frame (1) using a single-sided mount. The quick-release arrangement includes a number of levers (12) each movable between a closed position, in which the wheel is retained to the bicycle hub, and an open position in which the wheel is freely removable. A locking ring (21) is mounted to the bicycle wheel and is rotatable between an open position and a locked position. When the locking ring (21) is in the locked position, hooks (24) on the locking ring (21) are engageable with pins (26) mounted on the levers (12), to prevent the levers (12) from moving out of their closed positions. The locking ring (21) may be mounted to a lever cover plate (18) which is fixed to the wheel and arranged so as to partially cover the levers (12) when they are in their closed positions. The lever cover plate (18) may have a window (27) through which an indicator is visible to indicate the position of the locking ring (21).
