The invention discloses a manual folding telescopic electric scooter, which belongs to the technical field of medical equipment, and includes a front axle assembly, a slide rail fixing plate, a slide fixing plate and a rear frame which are sequentially connected. After the matching, the slide rail fixing plate slides inside the slider fixing plate to complete the expansion and contraction; a fixed seat is symmetrically arranged on the rear frame, and the fixed seat is respectively connected to the seat support seat through the corresponding rotating plate. After cooperation, the seat supporting frame is fixed and fold by locking or unlocking the rotating plate. The invention has a lightweight body, which can be easily folded and retracted, and the volume is small after being folded and retracted. The manual folding telescopic electric scooter adopts electromagnetic automatic braking. The overall simple design is convenient and practical. It can easily complete the folding and retracting operation when traveling. The best travel tool for traveling alone, the entire device has a simple and compact structure and has good practicability.

A clamping mechanism is provided, the clamping mechanism have two clamps, a tensioning conduit corresponding to each of the clamps, and an actuator for simultaneously tensioning the two clamps by way of the tensioning conduits. Each clamp has a bracing element and a gripping segment, and when the clamps are tensioned along the tensioning conduit, the gripping segment of each clamp is drawn towards the corresponding bracing element. Also provided is a bicycle drive assembly, the assembly has two clamps for fixing to a bicycle, a drive mechanism for driving a bicycle wheel, and two elongate supports extending from the drive mechanism to corresponding clamps. When applied to a bicycle, a wheel of the bicycle passes partially between the elongate supports.

An electric drive motorcycle (100) allows a suitable configuration of all the components deputed to the electric supply of the motorcycle electric drive, and comprises: a front portion comprising one or more front wheels (103) and a handlebar (104); a rear portion comprising a saddle (101), a shell body (107) arranged below said saddle (101), and a rear wheel (105) arranged below said shell body (107); an intermediate portion (108) extending as a connection between said front portion and said rear portion; an electric drive unit (8) connected to said rear wheel (105); and a hybrid supply unit supplying said electric drive unit (8), comprising at least a battery unit (115) and a combustion engine (116) actuating an electric generator (120) apt to supply said battery unit (115) and/or said electric drive unit (8), wherein said shell body (107) defines a housing space apt to receive at least said battery unit (115) and said combustion engine (116), with the related electric generator (120), placed side by side therebetween.

A tricycle for riding on any type of terrain, improving stability and safety in slow movement, having a structural chassis incorporating a rolling assembly made up of a rear wheel associated to a propulsion system and two front wheels linked to a driving handlebar, wherein the front wheels are incorporated in a height-tilting suspension, made up of articulated quadrilaterals able to be deformed independently with vertical movement depending on the individual resting of the front wheels on irregularities of the terrain, the height-tilting suspension linking to the handlebar, by means of a transmission, which links the height-oscillating movements of the articulated quadrilaterals of the height-tilting transmission with an equivalent lateral tilting of the handlebar, this transmission having a clutch which allows for enabling or disabling the linkage of the movements between the height-tilting suspension and the handlebar.

In a saddle-type electric, a lower spring supporting a lower surface of a battery is provided on a bottom portion of a battery case. A cover covering the battery includes an upper spring to catch the battery together with the lower spring in the up and down direction. When the battery is placed in the battery case and the cover closes, the lower spring supports the lower surface of the battery and is elastically deformable in an extension direction and a compression direction and the upper spring presses the upper surface of the battery and is able to elastically deform in an extension direction and a compression direction.

A suspension assembly for a cycle having improved stability includes a steering fork having a first arm and a second arm, each of the first arm and the second arm having a fixed pivot and a shock pivot, the space between the first arm and the second arm defining a wheel opening. A shock link has a shock link fixed pivot and a shock link floating pivot. A shock absorber has a shock gas spring comprising a shock spring body a shock gas piston having a first gas piston area, a spring unit having a spring gas spring comprising a spring body and a spring gas piston having a second gas piston area. A gas pressure inside the shock gas spring is equal to a predetermined pressure for a user's body weight to produce optimal ride conditions for the user's body weight.

Safe, three-wheeled tilting scooter or motorcycle frames with two front steerable, non-tilting wheels are described herein, as well as three-wheeled tilting vehicles with various propulsion systems mounted on such frames are also disclosed. Said vehicles are preferably non-polluting, such as electric or fueled by hydrogen.

A vehicle body includes a vehicle frame and an engine assembly, and further includes an intermediate supporting frame connected between the vehicle frame and the engine assembly. A first cushioning device is provided between the intermediate supporting frame and the vehicle frame. In the application of the vehicle body, since the first cushioning device is provided, the first cushioning device can effectively reduce vibration transmitted from the intermediate supporting frame when the vibration is transmitted to the intermediate supporting frame during the vibration of the engine assembly, and the vibration received by the vehicle frame may be much less than the vibration transmitted from the intermediate supporting frame, thus the vehicle frame can be effectively prevented vibrating heavily. Therefore, the heavy vibration of the vehicle body can be effectively reduced by means of the vehicle body.

A self-balancing transportation device having improved shock absorbing ability and operation. Several embodiments are disclosed including a single wheel or wheel structure device with foot platforms disposed for angular movement about an axis of rotation that is non-collinear with the axis of rotation of the drive wheel. Single and multiple wheel devices are disclosed as well as devices having independently movable foot platforms, and devices having load platforms that rotate independently and are movable longitudinally with respect to one another, among other embodiments.
