A three-wheeled vehicle includes a vehicle frame supported by a single wheel engaging the ground in the front and two wheels engaging the ground in the rear. The operator area of the vehicle may include seating for a driver and a passenger, one in front of the other. The three-wheeled vehicle is uniquely designed so that it can be easily modified by addition or removal of additional structures after it is purchased. The vehicle is ultra-narrow but achieves stability by unique mechanisms.

A self-propelled, one-wheeled vehicle includes a suspension system configured to dampen up-and-down motion of a board relative to the axle of a central wheel assembly when the vehicle encounters obstacles (e.g., bumps) on a riding surface. Illustrative suspension systems include a shock absorber and a swingarm that couple the axle to the board. The suspension system may be disposed completely below a foot deck of the vehicle.

A valve device includes an operating portion including an operating rod switchable between a first state where the operating rod is at a first position, a second state where the operating rod is displaced from the first position, and a third state where the operating rod is displaced from the first position, a push member that can advance by being pushed by the operating rod, a first valve that can be opened and closed in accordance with the amount of displacement of the operating rod and the push member from the first position, a housing storing the first valve, and a second valve that can open and close a communication passage allowing communication inside and outside the housing by switching operation of the operating rod so as to switch from the first state to the second state.

A position adjusting arrangement for use in a vehicle includes a seat for supporting a rider, a rear wheel and a front wheel, a steering arrangement including a handle bar for allowing the rider to control the steerable wheel, and a hub for interconnecting the components of the wheeled vehicle. The position adjusting arrangement includes an adjustable seat support arrangement movably connected to the hub, an adjustable handle bar support arrangement movably connected to the hub, and a releasable position locking arrangement configured to lock the position of the components of the vehicle relative to the hub. The hub may include a first portion and second portion, wherein the first and second portions are moveably connected to one another, such as by pivoting, sliding, or a combination of pivoting and sliding.

A suspension group for a motor vehicle, wherein said suspension group includes: a wheel guide, which extends along a longitudinal axis, which includes a wheel attachment for connection to a rotation pin of a wheel having a rotation axis orthogonal to said longitudinal axis, wherein the wheel guide extends between a first end and a second end, opposite the first end, a support arm functionally connected to the wheel guide respectively by means of: a first crank rotatably connected at said second end to the wheel guide and to the support arm; a second crank rotatably connected at said first end to the wheel guide and to the support arm, wherein the wheel guide elements, the support arm and the first and second crank define a suspension quadrilateral, wherein, between at least two of said elements chosen between the wheel guide, the support arm, the first and the second crank, a shock absorber group is interconnected in such a way that the shock absorber group varies its extension as the movement of the suspension quadrilateral varies.

The present disclosure relates to a system for control of front and/or rear suspensions of a bicycle. The system comprises at least one sensor and one control unit. The at least one sensor is connected to the control unit and the control unit is configured to receive information from the sensor, determine a ride state of the bicycle from the information and send a suspension setting signal to the front and/or the rear suspension corresponding to the ride state. The control unit is further configured to establish an event, the event comprising information about said ride state of the bicycle and a suspension setting signal to the front and/or the rear suspension corresponding to the ride state and defining a minimum duration in time for the event.

A detection device includes sensor device configured to obtain environmental information about surroundings of a small vehicle, an output unit outputting the environmental information to a control device of the small vehicle, and a mount configured to be attached to a rider of the small vehicle so as to hold the sensor device and the output device.
