A foldable bicycle has a front assembly including a front frame member supporting a front wheel and a handlebar column. A rear assembly has a rear frame member supporting a rear wheel, a seat structure and a drive mechanism. A central joint interconnects the front and rear frame members to form an articulated main frame. The articulated main frame is pivotable about a pivot axis between an assembled state such that the front and rear wheels are coplanar in a first plane that includes a vertical axis and a longitudinal axis and a collapsed state such that the front wheel is laterally offset and adjacent to the rear wheel. The front assembly rotates towards the rear assembly about the pivot axis when the articulated main frame is pivoted from the assembled state to the collapsed state.

A foldable scooter comprises a front wheel unit, a frame unit, a rear wheel unit, and a. seat unit. The frame unit comprises a connecting rod, a linking rod, and a stand, wherein the stand comprises a footboard, a chassis, and two side cover plates located on two sides of the footboard, the linking rod is located in a space between the footboard and the chassis, the connecting rod has an end fixedly connected with the front wheel unit and an end stretching into the middle of the footboard from front to be fixedly connected with the front end of the linking rod, and the rear end of the linking rod is fixedly connected with the rear wheel unit. The foldable scooter is simple in structure, convenient to operate, and capable of being folded to he stored and transported easily.

A saddle member is attached to at least one of an upper end portion of a first frame member and an upper end portion of a second frame member of a main frame mechanism and remains to be in a state of being attached to at least one of the upper end portion of the first frame member and the upper end portion of the second frame member in a folded mode, a seated driving mode, and a standing driving mode, with locking function of a third lock mechanism.

Disclosed herein is a folding bicycle comprising a handlepost joint and two joints in the mainbeam forward of the seat tube, wherein the pins of the hinges in the two mainbeam joints (i) are located on opposite sides of the mainbeam when viewed in a top view, and (ii) when the bicycle in folded, place the front wheel parallel to rear wheel and the wheel axles inline on the same lateral axis or on parallel lateral axes, wherein the wheels roll in parallel track.

Folding bicycle comprising a frame with a front frame portion on which is mounted a front wheel (1) and a rear frame portion (A) on which is mounted a rear wheel (2). The front frame portion includes an upper bar (10), a seat bar (5) and an oblique bar. The rear frame portion comprises at least one seat stay (8), at least one lower bar (9) and the seat bar (5). The oblique bar comprises an upper oblique rod (14) and a lower oblique rod (15). The lower oblique rod (15), the upper oblique rod (14), the upper bar (10) and the seat bar (5) are interconnected by joints (P1, P2, P3, P4), in this order, so as to form an articulated quadrilateral (D) deformable between a folded position and an unfolded position.

An electric scooter is disclosed that includes a concaved-shaped center frame comprising a first and second curved members, a concaved-shaped rear frame hingebly attached to the center frame about a first axis, a front frame portion hingeably attached to the center frame about a second axis perpendicular to the first axis, and support cables coupled at a first end to the front frame portion and at a second end to the rear frame.

In an aspect, a compactable bicycle is provided, comprising a base frame portion and a steering structure, at least one of which has a first and a second frame element. Each frame element has a locking surface, an end, and an aperture. The frame elements are positionable in a first position wherein the first and second apertures are aligned and the locking surfaces face away from one another, and in a second position in which the apertures are unaligned. A plunger has first and second plunger locking surfaces and is movable to a clamping position where it extends in both the first and second apertures and engages the first frame element locking surfaces, and a release position wherein the plunger retracts from the second aperture sufficiently to permit the first and second ends to be separated from one another.

Some embodiments are directed to a foldable vehicle for use as a vehicle if being unfolded, and for use as a trolley if being folded. The vehicle in its folded configuration may also be placed in an upright parking position. The vehicle includes a first side frame coupled to a first wheel, a second side frame coupled to a second wheel and a coupling frame. The coupling frame includes a hinge joint between a first end and a second end of the coupling frame. The first end is hinged to the first side frame and the second end is hinged to the second side frame. When the first wheel translates towards the second wheel, the hinge joint moves from one side of the second wheel to the other side of the second wheel.

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 foldable personal such as a tricycle which can be convertible into a stroller, is configured for accommodating a child therein and for preventing, when desired, the child from being able to steer the vehicle, vehicle having an operational state and a storage state, in which it can take an extremely compact form. The vehicle has a longitudinal axis lying in its vertical plane of symmetry and having a horizontal reference plane perpendicular to the plane of symmetry, and it takes its compact form in the storage state both in the direction along its longitudinal axis and in the directions perpendicular to this axis both along the plane of symmetry and perpendicular to the plane of symmetry.
