A vehicle including a single front wheel arranged on a center line extending in a front-rear direction, two rear wheels arranged on a left side and a right side of the center line, a steering part arranged above the front wheel, a placement part on which feet of an occupant are placed, a first member rotatably supporting the front wheel and supporting the front wheel in a steerable manner by the steering part, a second member arranged behind the first member to rotatably support the two rear wheels, and a connecting part connecting the first member and the second member swingably in a left-right direction about an axial line extending in the front-rear direction. The placement part is supported by the second member.

A vehicle includes a vehicle body, a front wheel that is disposed anterior to the vehicle body and that is steerable about a steering axis, and a front fork that supports the front wheel. The vehicle body includes a vehicle body frame and a steering rotation unit that is supported on the vehicle body frame and that rotates about the steering axis. The vehicle includes a variable trail length mechanism. The variable trail length mechanism includes an oscillation shaft that extends in a vehicle width direction to thereby connect the front fork oscillatably with the steering rotation unit. The oscillation shaft is disposed at a position overlapping an axis of the front fork in a vehicle side elevational view.

A device attachable to a bicycle to prevent cables of the bicycle from wrapping around a steering tube is disclosed. The device includes an arm secured to a steering tube of the bicycle. The device includes a stop attached to the arm, to permit rotation of the steering tube about an axis of rotation relative to a head tube only between a first position and a second position.

A roller board device like a skateboard or scooter operated by a user with one or more user-maneuverable wheel assemblies that are automatically returned to their true north position is provided according to the invention. The roller board device comprises an elongated deck, at least one wheel assembly, a rotation assembly operatively engaging and extending through the opening in the deck, one end of the rotation assembly being connected to the wheel assembly positioned below the deck, the other end of the rotation assembly being connected to a user interface member extending upward beyond the top surface of the deck, and a north-seeking return mechanism secured to the deck containing an engagement member movable along a linear axis within a housing and engaging a spring disposed between the engagement member and an interior wall of the housing, the rotation assembly operatively connected to the engagement member to convert rotational movement of the rotation member into linear movement of the engagement member. When the user applies rotational force to the user engagement member to turn it to the left or right, the rotation assembly and wheel assembly are rotated in the same direction and degree to allow the roller board device to be turned, the rotated rotation assembly interacting with the engagement member of the north-seeking return mechanism to move the engagement member along its linear axis to a retracted position to compress the spring. But, when the user releases the rotational force upon the user interface member, the spring extends from its compressed state to its elongated state to move the engagement member of the north-seeking return mechanism back along the linear axis from its retracted position to its standby position, counter interacting with the rotation assembly to return the wheel assembly of the roller board device to its true north position.

A vehicle includes a main body, a steerable wheel, a steering, a steering actuator, and an electronic controller. The main body includes a saddle. The steerable wheel is coupled to the main body via a suspension. The steering is turnably coupled to the main body to steer the steerable wheel. The steering actuator is configured to apply steering torque to the steerable wheel. The electronic controller is configured to control the steering torque using the steering actuator and configured to generate steering damper torque to the steerable wheel using the steering actuator upon determining a reduced contact of the steerable wheel with a traveling surface with respect to a first prescribed threshold.

A foot-deck-based vehicle having an adjustable steering characteristic is provided. The foot-deck-based vehicle has a foot-deck with a front end, a rear end, and at least one rear wheel proximal to the rear end. A front wheel assembly is coupled to the foot-deck proximal to the front end to pivot relative to the foot-deck about a front wheel assembly pivot axis that is at an acute angle to a vertical axis when the foot-deck-based vehicle is upright. The front wheel assembly includes at least one front wheel rotatably coupled to a front wheel support. A steering characteristic adjustment structure adjustably controls a steering characteristic of the foot-deck-based vehicle.
