An ergonomic and rider-friendly auto-balancing personal transportation device. The device may have a central wheel structure with one or more tires and deployable foot platforms located on both sides of the central wheel structure. The platforms may be linked to a handle, such that lifting the handle retracts the foot platforms and releasing the handle may deploy them. The tire size and platform size may be set so that the device is easy to step on to, and the distance to ground when dismounting is reduced. Dual tire and single wider tire embodiments. Embodiments that allow different or multiple rider orientations are also disclosed, as are other features and embodiments.

A folding personal mobility vehicle includes a foothold part provided with a wheel, a handle part provided with a handle, and a hinge structure between the foothold part and the handle part. The foothold part and the handle part are each configured to be folded using the hinge structure and the foothold part and the handle part are configured so that the foothold part is positioned between the handle parts in a folded state.

A backpack type self balancing scooter having a foot-driven steering apparatus mounted thereon is provided, including: two wheels having motors mounted thereon; a motor housing for mounting the motors therein in such a manner as to allow rotary shafts of the motors to be located linearly to each other; a footrest; a shuttle ring mounted on any one side of the footrest; an erecting housing, a controller mounted on the upper portion, a cover disposed coveringly on top thereof, and an insertion hole formed on the center of the cover; a saddle; and a backpack. The rider walks in the state of carrying the backpack on the back, or puts the backpack on the around, sits on the saddle to drive the self balancing scooter in the state where both hands are free, while conducting the direction changes through the shuttle ring turned with his or her foot.

A vehicle may include a frame having a first portion, a second portion, and a tiller. The first portion may be coupled to a front wheel and to the tiller. The second portion may be coupled to a rear wheel and detachably coupled to the first portion. A method of transitioning the vehicle between a folded configuration and an unfolded configuration may include rotating the first portion of the frame relative to the second portion of the frame between the folded configuration and unfolded configuration to cause the first portion of the frame to lock to the second portion of the frame.

A portable conveyance has a deck, a front drive wheel proximately disposed to a first end of the deck and a rear drive wheel attached proximate to a second end of the deck. A guide roller assembly attached proximate to the rear drive wheel. The guide roller assembly has a first rotational axis and the rear drive wheel rotates about a second rotational axis different from the first rotational axis and parallel to the first rotational axis, such that the guide roller assembly is not in contact with a substantially flat surface when the first and rear drive wheels are in contact with the substantially flat surface, and the guide roller assembly is in rotational contact with the surface when the deck is lifted into a towing position.

A bicycle includes a frame having four bar elements, wherein the first bar element is pivotally connected to the second bar element by a first hinge, the second bar element is pivotally connected to the third bar element by a second hinge, the third bar element is pivotally connected to the fourth bar element by a third hinge and the fourth bar element is pivotally connected to the first bar element by a fourth hinge, a front axle protruding from the third bar element for mounting a front wheel, a rear axle protruding from the first bar element for mounting a rear wheel, wherein the fourth hinge is disposed rear of the rear axle, at least one handlebar attached to the third bar element.

A foldable bicycle structure comprises a supporting frame (2) having a rear wheel (3) and a front wheel (4), a handlebar (5) fastened to the frame (2) and a seat post (6). The supporting frame (2) is divided into a front portion (9) and a rear portion (10) adapted to be connected to respective wheels (3, 4) and reciprocally hinged around a first hinge axis (11) to switch between an extended use configuration to a compact configuration. The supporting frame (2) is also provided with one or more straps (14, 15) each having one end fixed to the supporting frame (2) and one free end provided with a hook to allow the respective strap to be unwound (14, 15) and its hooking to another part of the structure and be used as a shoulder strap for transporting the structure in a compact configuration.
