A method for regulating vehicle access comprises receiving, from an electronic device of a user, a request to access a vehicle. The vehicle can be disposed at a designated geographic location. Next, geographic information of the user is received from the electronic device. The geographic information is determined with the aid of the electronic device of the user. The user is then provided access to the vehicle if, based on the received geographic information, a geographic location of the user is within a given distance from the designated geographic location of the vehicle.

A three-dimensional folding frame is disclosed including a first pivot portion for providing a front folding wheel frame with movable folding; a second pivot portion for providing a rear folding wheel frame with movable folding; a third pivot portion for providing a handlebar vertical rod with rotatable folding; and a fourth pivot portion for providing a crossbar with rotatable folding. The crossbar includes a first folding arm and a second folding arm; the first folding arm is movably connected to the front folding wheel frame by means of the first pivot portion; the front folding wheel frame rotates about the first pivot portion and can move relative to the first folding arm; the second folding arm is movably connected to the rear folding wheel frame by means of the second pivot portion.

A walking vehicle the vehicle frame comprises a vertical tube adjacent to the two front wheels, and a lateral tube at the top end of the vertical tube. The rear wheel is connected to a left pedal and a right pedal. The central rod passes through the lateral tube. The left handlebar sheathes and the right handlebar sheathes each one end of the central rod. The left handlebar are connected to the left pedal. The right handlebar are connected to the right pedal. The gear set comprises a first bevel gear mounted at the right handlebar, a second bevel gear mounted at the right connecting rod, and a connecting gear with a mounting rod passing through the central rod thereof and engaging the first bevel gear and the second bevel gear. This has the effect of facilitating the operation of the walking vehicle for improved handling maneuverability and stability.

A tiltable vehicle has a pair of front wheels coupled to a tiltable chassis by a tilt linkage, such that the pair of front wheels and the chassis are configured to tilt in unison with respect to a roll axis of the chassis. The tilt linkage includes a four-bar linkage having a pair of upper bar segments coupled to the chassis at spaced-apart respective inboard joints. In some examples, the inboard joints of the upper bar segments are each disposed outboard of a central chassis joint of a lower bar of the tilt linkage. An orientation sensor is configured to detect directional information regarding a net force vector applied to the chassis, and a tilt actuator operatively coupled to the chassis and configured to selectively tilt the chassis. A controller is configured to selectively control the tilt actuator based on the directional information from the orientation sensor.

A snowmobile having enhanced steering control has driving control system including an electrically actuated device coupled to a steering system having a user operated steering element with the device applying torque to the steering system, a throttle, a plurality of sensors including a torque sensor and at least one additional sensor to generate terrain condition data and operational data, and at least one controller coupled to the device and the sensors. The at least one controller selects a terrain condition mode using the generated terrain condition and generated operational data, determines the torque to apply responsive to the angle and speed of rotation of user operated steering element, and operates the electrically actuated device to apply the torque to the steering system, with the torque being applied only by the electrically actuated device.

A control device mountable to a handlebar of a bicycle includes a housing, a lever coupled to and pivotable relative to the housing, and a master cylinder portion supported by the housing. The master cylinder portion has a fluid cylinder. The fluid cylinder has a first end and a second end opposite the first end with a cylindrical wall therebetween. An opening extends through the master cylinder portion, from the first end to the second end. The control device also includes a plug removably connected to the master cylinder portion via the opening at the first end of the fluid cylinder, and a piston assembly supported by the housing. The piston assembly is movable relative to the master cylinder portion. The housing is made of a first material, and the master cylinder portion is made of a second material. The second material is different than the first material.

The subject of the invention is a first aid kit into bicycle handlebars that comprises a compression storage portion, wherein the compression storage portion defines a space adapted for storing objects and an elongated retraction element attached to one end of the compression storage portion, wherein the other end of the compression storage portion is provided with a plug. The plug can be used to fix the compression storage portion in the handlebars and to define a clearance between the first aid kit and the handlebars. The retraction element (e.g., a string or a cord) can be used for retracting the compression storage portion into the handlebars. Furthermore, the first aid kit can comprise a firm storage portion which can provide an additional storage space.
