A walker specialized for use on trails by pushing and walking, rather than riding on, with no drivetrain, along with a method of using the walker on trails is provided. The walker can include a frame, two inline wheels, and a handlebar steering mechanism. The walker can further include a braking mechanism, an elbow rest, an electric motor, and racks and/or carriers for gear.

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.

A mobility for storing a personal transportation includes a first storage unit formed on a side of the mobility and configured for storing the personal transportation therein without folding thereof; a second storage unit formed on a side of the mobility and configured for storing the personal transportation therein after the personal transportation is folded; a controller configured to control the first storage unit and the second storage unit in response to a mobility user's request; and a server configured to receive information related to whether the first storage unit and the second storage unit are used, and a remaining battery capacity, use time, and movable distance of the stored personal transportation from the controller, and to communicate with the mobility user.

A folding bicycle and method for folding the folding bicycle is provided. The folding bicycle comprises a frame having a first end and a second end; a first wheel connected to the second end of the frame, the first wheel and the frame being located in a first plane; a fork having a first end and a second end, the second end of the fork pivotally connected to the first end of the frame thereby allowing the fork to pivot about the first plane; a second wheel connected to the first end of the fork, the second wheel and the fork being located in a second plane; a first pivot member having a first pivot axis to allow the first end of the fork to pivot towards the second end of the fork about the first pivot axis; a second pivot member having a second pivot axis to allow the first end of the frame to pivot towards the second end of the frame about the second pivot axis; and a third pivot member having a third pivot axis to allow the second end of the frame to pivot towards the first end of the frame about the third pivot axis.

A variety of scooters are disclosed. In some embodiments, a scooter can include a pivot assembly that allows the scooter to move between a folded and unfolded configuration. The pivot assembly can include a knob that frees a pin from a bracket to allow the scooter to fold. Turing the knob increases compressive forces on elements of the pivot assembly to reduce rattling noise and wobbling movement when the scooter is in use. Some embodiments of the scooter can include a center stand that can be deployed from either side of the scooter deck to stabilize the scooter when the scooter is stationary. Certain embodiments have an ergonomic handgrip.

The device provides an energy return mechanism associated with flexing and straightening of the scooter rider's support leg. The device includes an energy return mechanism having an end connected to the scooter such that resilient force exerted by the mechanism is longitudinally aligned with the scooter to act in a generally rearward/upward direction. A free end of the mechanism cradles the front of the rider's support leg, just below the knee. When the rider flexes the support leg, the resilient mechanism distorts in a longitudinal direction. When the rider straightens the leg, the forces stored in the resilient mechanism supplement the force of the rider's muscles. Thus, the device reduces the amount of energy used by the rider. The mechanism can be configured as an accessory to a conventional scooter or be integrated into a scooter. Certain embodiments are foldable and compatible with the foldable scooters.

A vehicle includes a body and a cover rotatably connected to the body. The vehicle further includes a control bar rotatably connected to the cover. The cover is rotatable onto the body to put the cover in the stowed position from an extended position. The bar is between the cover and the body when the bar is in the stowed position.

A convertible, self-propelled, motorized mobility assistance device in a plurality of embodiments is provided, comprising a scooter-like chassis (1400) with support deck (300) portion, a handlebar (700), and at least one removable, interchangeable knee rest (800) or seat attachment (1300); wherein the device is mounted atop and driven by at least three motorized wheels (400, 500) which are connected to a source of power and propulsion (1200), and drive (1100). The device further includes a steering system, braking system, and mechanisms for height-adjustability, comfort, and portability.

A foldable self-supporting scooter comprises at least three wheels, a steering column, a footboard, a front axle for receiving at least one front wheel, a rear suspension for receiving at least one rear wheel, and a folding mechanism that autonomously folds the scooter, wherein a synchronization rod provides that the center of gravity of the scooter remains between the front and rear wheels at all times during the folding operation, without the need for the scooter to be held by the user and without tipping over.

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.
