A scooter apparatus including a steering assembly having a pivotable steering post having a pivotal axis; a handle-bar securely attached to the steering post; a pair of front wheels; a steering mechanism configured to steer the front wheels; a wheels-pivoting-mechanism configured to pivot the pair of front wheels; and a steering-tilt assembly configured to synchronously tilts the steering post towards the inside periphery of the turning curve, when pivoting the steering post. The rate of the tilt of the steering post, towards the inside periphery of the turning curve, is proportionally related to the pivoting rate of the steering post, and configured to vary depending on speed. The scooter further includes a deck assembly having a standing board and a rear wheel assembly. An interface assembly interconnecting the deck assembly with the steering assembly. The scooter is foldable and may include a detachable bag.

A scooter includes a frame which has a footboard and supports a rear wheel, a steering column provided with a front wheel pivotably mounted on the frame, and a motor provided with a drive shaft coupled to the rear wheel via a transmission system. The transmission system includes a rear transverse shaft having a first end portion and a second end portion rotatably coupled to the rear wheel; —a gear system having a sprocket coupled rotatably to the first end portion and in meshing engagement with a toothed gear rotatably coupled to the drive shaft; and —a rear structure attached to the frame, supporting the gear system and the rear transverse shaft, and extending laterally along one side only—right or left—of the rear wheel, such that the second end portion extends from the rear structure to support the rear wheel in a cantilevered fashion.

A collapsible bicycle includes a collapsible tube, a spring-loaded detent, a rod, a hook, and a security element. The collapsible tube includes a first section, a second section, and a hinge for pivotally connecting the first and second sections to each other. The spring-loaded detent is connected to the second section of the collapsible tube and formed with an external end. The rod is connected to the second section of the collapsible tube. The hook is pivotally connected to the first section and formed with a hook engageable with the rod to keep the first and second sections of the collapsible tube coaxial with each other. The security element is pivotally connected to the first section of the collapsible tube and formed with a concave portion for receiving the spring-loaded detent to keep the security element covering the hook, thereby keeping the hook engaged with the rod.

A foldable bicycle (100) having a riding configuration and a folded configuration includes a first wheel (102) and a second wheel (104) interconnected by a frame (106). At least the first wheel (102) has an open centre (108) and includes an annular rotor (110) engageable with the ground in the riding configuration of the bicycle (100) and an annular stator (114) carrying the annular rotor (110), and the frame (106) has a pivotal connection with the stator (114) of the first wheel (102) whereby the frame (106) is pivotable relative to the first wheel (102) for folding the bicycle (100). The frame (106) and the second wheel (104) connected thereto are together so dimensioned and arranged to fit within the open centre (108) of the first wheel (102) in the folded configuration of the bicycle (100).

A latch mechanism includes a first and second latch body. The first and second latch body respectively includes a first and second base, a first and second latch portion and a first and second acting portion. The first latch body disposes through the second base. The second acting portion is pivoted to the second base. The second latch portion is disposed on the rotational path and limited to the first latch portion. The second acting portion includes a first and a second pushing structure. When the second acting portion is rotated along the rotational path, the second latch portion is pushed by the first pushing structure such that the second latch portion is disengaged from the first latch portion, and then the first acting portion is pushed by the second pushing structure such that the first latch body is disengaged from the second latch body in a releasing direction.
