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 bicycle and frame is disclosed including a rear frame structure including a seat tube, a bottom bracket shell and a chainstay terminating in a rear wheel mount. A forward end of the chainstay, a lower end of the seat tube, and the bottom bracket shell are rigidly connected. A front frame structure includes a down tube rigidly connected to a forwardly disposed head tube and connected to the rear frame at a pivot proximate the bottom bracket shell facilitating pivoting of the front frame with respect to the rear frame in a common vertical plane. A frame lock when engaged substantially immobilizes the pivot to place the frame in a riding condition and when disengaged facilitates relative movement of the down tube and the seat tube towards each other about the pivot in the common vertical plane to place the frame in a collapsed condition such that the down tube lies alongside the seat tube.

A tri-mode collapsible scooter includes: a deck; a stem; handlebars; a head tube; a neck hinge; a deck hinge; a wheelset; a neck control; and a deck control. The deck includes: a front deck section; a rear deck section; and a deck hinge interposed between the front deck section and the rear deck section. The neck control is configured to release the neck hinge for transition between an open neck position and a closed neck position. The deck control is configured to release the deck hinge for transition of the deck between an open deck position and a closed deck position. The deck hinge occupies the open deck position and the neck hinge occupies the open neck position in a ride mode; and the deck hinge occupies the closed deck position and the neck hinge occupies the closed neck position in a tow mode.

Snow vehicle is disclosed. The snow vehicle includes a pair of runners configured to support the snow vehicle travelling over snow and/or ice, an electric motor, and a traction wheel, powered by the electric motor, and configured to cause a propulsion for the snow vehicle while rolling in contact with the snow and/or the ice. The traction wheel is positioned in front of the pair of runners.

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.

The present disclosure relates to a novel portable electric vehicle, which comprises two front-rear folding mechanisms, a left-right folding mechanism, and an operating mechanism, wherein the two front-rear folding mechanisms for supporting a driver are arranged respectively on the left side and the right side of the bottom of the electric vehicle, the rear ends of the front-rear folding mechanisms are both provided with driving wheel mechanisms, and the front ends of the front-rear folding mechanisms are both provided with rotating wheel mechanisms; two ends of the left-right folding mechanism for driving the two front-rear folding mechanisms to get close to each other are connected respectively to the two front-rear folding mechanisms; and the operating mechanism for controlling the running of the electric vehicle is mounted on the left-right folding mechanism. The present disclosure also relates to a method for controlling the drive of the novel portal electric vehicle, which utilizes an Arduino circuit board to control the running of the electric vehicle. The novel portable electric vehicle has the advantages of good driving experience, small size, light weight, convenience in folding and easiness in operation, and belongs to the technical field of electric vehicles.

A foldable personal such as a tricycle which can be convertible into a stroller, is configured for accommodating a child therein and for preventing, when desired, the child from being able to steer the vehicle, vehicle having an operational state and a storage state, in which it can take an extremely compact form. The vehicle has a longitudinal axis lying in its vertical plane of symmetry and having a horizontal reference plane perpendicular to the plane of symmetry, and it takes its compact form in the storage state both in the direction along its longitudinal axis and in the directions perpendicular to this axis both along the plane of symmetry and perpendicular to the plane of symmetry.

A folding urban mobility vehicle includes a frame, a pair of front wheel assemblies carried by respective front arms articulated to the frame about a first axis, and a rear wheel assembly carried by a rear arm articulated to the frame about a second axis. In a folded configuration of the vehicle the front wheel assemblies are located within the frame and the rear wheel assembly extends within the frame between the two front wheel assemblies.

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.
