A straddle type electric vehicle comprises a main frame, a motor unit including an electric motor, and a battery that supplies power to the motor unit. The main frame includes a left and right pair of portions. The motor unit is disposed overlapping the main frame in a side view of the vehicle. A motor shaft of the electric motor is disposed above the pivot shaft and rearward in the vehicle longitudinal direction.

The present invention features a locking clamp capable of securing a post into a bicycle frame such that only a user can remove the locking clamp. The locking clamp may comprise a lock capable of accepting an unlocking method that only the user may utilize, ensuring security of the post to protect items stored in the post (e.g. a bicycle repair assembly). The unlocking method may depend on the type of lock implemented. The locking clamp may further comprise a first jaw extending from the lock, a second jaw extending from the lock, and a screw connecting the first jaw and the second jaw. Actuating the screw may move the first jaw closer to the second jaw thus tightening the locking clamp around an interface of the post and the bicycle frame.

A pneumatic-hydraulic control valve includes a valve base and a valve stem movably disposed in the valve base. A first inner oil guiding hole of the valve stem communicates with a first outer oil guiding hole of the valve base. A second inner oil guiding hole of the valve stem does not communicate with a second outer oil guiding hole of the valve base when the valve stem is closed, and communicates with the second outer oil guiding hole of the valve base when the valve stem is opened. Further, the valve stem has a first stressed portion for bearing a fluid closing force and a second stressed portion for bearing a fluid opening force. The outer diameter of the first stressed portion is larger than that of the second stressed portion. Thus, the present invention reduces a valve opening force without affecting the sealing effect.

A pneumatic-hydraulic type control valve includes a cable attached to a fixed base, a valve base disposed in the fixed base, and a valve stem disposed in the valve base and driven by the cable to be opened. First and second oil guiding holes of the valve base communicate with each other when the valve stem is opened, and the first and second oil guiding holes of the valve base do not communicate with each other when the valve stem is closed. Further, the valve stem has a first stressed portion for bearing a fluid closing force and a second stressed portion for bearing a fluid opening force. The outer diameter of the first stressed portion is larger than that of the second stressed portion. Thus, the present invention achieves effects of simplifying structure and accurate actuation without affecting the sealing effect.

An operating device for a height-adjustable seatpost tube including a lifting magnet. The lifting magnet has a magnetic core surrounded by a coil. The magnetic core cooperates with an actuating device of a lifting device, the lifting device being a pneumatic lifting device for height-adjustment of the seatpost tube and thus for heigh-adjustment of the seat, for example.

An electric scooter includes: an upper plate member including two roll tubes and a shaft tube pivotally connected to a standing tube and inserted into the roll tubes, the standing tube having a hooking part and a connection part disposed between the roll tubes and inserted by the shaft tube; a lower plate member including a pressing part positioning with the hooking part; two frames pivotally connected between the upper and lower plate members through bolts, each opened frame including a clip tightly covering the standing tube; a stopper disposed between the upper and lower plate members and positioning the closed frames; and a pivotal connection seat including two frame fitting members covering the tapered portions and having a quick release member, a tapered seat base having a top part combined with a cover frame of the seat cushion provided with a quick release member fixed to a positioning hole.

A collapsible mobility scooter includes a chassis and a transformation actuator. The chassis includes a rear frame a front frame pivotally connected to a rear frame. The front frame is pivoted to the rear frame when the chassis is in a collapsed position. The front frame is pivoted away from the rear frame when the chassis is in an extended position. The transformation actuator includes a rear end connected to the rear frame and a front end connected to the front frame.

The present disclosure relates to a seat post for a bicycle, a moped or the like, comprising a seat post tube, wherein said seat post tube comprises an opening member that is configured to allow a closure element of the seat post to perform a movement, by means of which a region inside the seat post tube can be accessed in order to insert or remove an elongated object, wherein said seat post tube comprises an upper portion and a lower portion opposite the upper portion, said upper portion being configured to be connected to a seat clamping device and/or to a seat, and wherein the closure element is preferably provided in the region of the upper portion. The present disclosure furthermore relates to a frame for a bicycle, a moped or the like, a use of a seat post or frame according to the disclosure, a folding lock, a locking system and a lock/handlebar combination.
