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.

A turning mechanism and a handle. The turning mechanism comprises: a first connecting rod (201) and a second connecting rod (202); the first connecting rod (201) is provided with a first bevel end, the second connecting rod (202) is provided with a second bevel end, and the second bevel end matches with the first bevel end, so that the second connecting rod (202) rotates along the end face of the first bevel end; in the rotating process, the first bevel can be attached to the second bevel, so that no gap exists between the first connecting rod (201) and the second connecting rod (202).

A scooter includes an elongated foot rest base extending from a first end to a second end; a first wheel secured to the first end of the foot rest base; a second wheel secured to the second end of the foot rest base; a pivot joint extend through a thickness of the foot rest base, the pivot joint being positioned between the first end and the second end; a locking mechanism secured to the foot rest base and configured to lock the joint in a fixed position; a backrest pivotally secured to the second end of the foot rest base; and a storage compartment rigidly secured to the backrest.

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.

A child's riding vehicle can be quickly reconfigured between a balance bike configuration and a pedal-powered bicycle configuration, suitable for children of different ages, without removing any parts to be stored separately. The pedal crank arms can be repositioned on the crank and the pedal axles can be pivoted so that in the balance bike configuration: the pedal crank arms are positioned adjacent to one another and generally upward; the pedal axles are pointed mostly rearwardly but also slightly inwardly rather than extending transversely side-to-side; and the crank arms and pedal axles are telescoped in. The result is that in the balance bike configuration the pedals and crank arms are compacted and folded out of the way so as not to interfere with the child riding the vehicle.

The present invention relates to an electric motorcycle realized so that it can be subjected to a simple maintenance process. Such motorcycle is realized so that all the components at major risk of failure or deterioration are grouped in an unique compact and easily removable block called “block of electric components”. Moreover, the structure of the same motorcycle is conceived so that the extraction of said “block of electric components”, even if it is bulky and heavy, results simple and that it is also reduced at minimum the risk that such operation occurs in an incorrect way, or that it can provide other kinds of damage. All this aims at making the motorcycle maintenance and the restoration of its full function possible also at not specialized sites.

A handlebar foldable mechanism and a tool for riding instead of walk are provided. The handlebar foldable mechanism includes a base, a stem, a first locking assembly, a lever and a second locking assembly. The base is provided with a first snapping groove, the stem is connected to the base and is pivotable between an unfolded position and a folded position, the first locking assembly is pivotably connected to the stem and is configured to be engaged with the first snapping groove when the stem is pivoted from the folded position to the unfolded position, the lever is pivotably connected with the base, the second locking assembly is mounted to the lever, and the second locking assembly is configured to be connected to at least one of the base and the stem when the stem is at the unfolded position.
