An adjustable assembly for a bicycle includes a first support having an interior surface and a second support slidably positioned within at least a portion of the first support. One of the first support and the second support is adapted to attach to a first bicycle portion, and the other of the first support and the second support is adapted to attach to a second bicycle portion. Further, the second support comprises an expansion portion configured to be moved between an expanded position and a retracted position. The expansion portion is configured to engage the interior surface of the first support when the expansion portion is in an expanded position. In addition, the first support is configured to be selectively moved relative to the second support when the expansion portion is permitted to assume a retracted position. In some embodiments, the first bicycle portion comprises a bicycle frame and the second bicycle portion comprises a bicycle saddle. In other arrangements, the first bicycle portion comprises a fork assembly and the second bicycle portion comprises a handlebar assembly.

A center of gravity (C/G) control system for a vehicle includes sensors to measure the center of gravity shift and mass shift of the human body in relation to the vehicle, a controller to determine outputs, a dynamically adjustable vehicle system, and a power supply. The sensor measures the direction and rate of shift of the center of gravity and mass shift of the human and creates a representative input signal. The controller determines the appropriate outputs in response to the relative center of gravity shift data received. The dynamically adjustable vehicle system receives the controller output and performs the expected action.

According to some embodiments, an adjustable assembly for a bicycle comprises a first support and a second support slidably positioned within at least a portion of the first support, such that one of the first support and the second support is adapted to attach to a first bicycle portion and the other of the first support and the second support is adapted to attach to a second bicycle portion. In some embodiments, the second support comprises an expansion portion configured to be selectively moved between an expanded position and a retracted position. In one embodiment, the expansion portion is configured to contact and engage at least one portion of the first support when the expansion portion is in an expanded position, and the first support is configured to be selectively moved relative to the second support when the expansion portion is permitted to assume a retracted position.

An adjustable-height bicycle seat post assembly comprises a hollow seat post for supporting a bicycle seat slidably on plastic guides or shims inside a hollow tube. The hollow tube clamps into the frame of a bicycle. A mainspring forces the post upward, but a locking mechanism interconnects the post with the tube in various fixed positions relative to the tube. The locking mechanism includes a housing, which supports a plunger for reciprocating movement into and out of engagement with holes on the post. The locking mechanism is affixed to the outside of the tube to bear shearing forces on the plunger. An endcap on the locking mechanism and a topcap on the tube protect the assembly from foreign debris. The locking mechanism may be manipulated remotely using a magnetic switch assembly or manually using a mechanical assembly. A lost motion coupling is integrated into the locking mechanism and/or actuator assembly to enable the remote actuator to be moved or deployed while the latch remains trapped under the influence of a dominant shear load. The lost motion coupling is also effective to allow an operator to deploy the remote actuator at any convenient time prior to a desired change in seat height.

An adjustable height bicycle seat post assembly comprises a hollow seat post for supporting a bicycle seat slidably supported on plastic shims inside a hollow tube. The hollow tube clamps into the frame of a bicycle. A main spring forces the post upward, but a locking mechanism interconnects the post with the tube in various fixed positions relative to the tube. The locking mechanism includes a foundation and a projection extending from the foundation having a counterbore for guiding a plunger into holes on the post. The locking mechanism adheres to the outside of the tube to bear shearing forces on the plunger. An endcap on the locking mechanism and a top cap on the tube protect the assembly from foreign debris. The locking mechanism may be manipulated remotely using a magnetic switch assembly or manually using a manual assembly.

A height adjustable seatpost assembly is provided with first and second tubes, a ratchet mechanism and a drive source. The first and second tubes are telescopically arranged. The ratchet mechanism includes a ratchet tooth structure and a pawl structure. The pawl structure is engaged with the ratchet tooth structure in a lock position. The pawl structure is movably coupled with respect to the ratchet tooth structure in a movable position such that the first and second tubes are movably arranged relative to each other in at least one axial direction of the first and second tubes. The drive source moves the pawl structure between the lock position and the movable position in response to operation of the drive source. The drive source further axially moves the first and second tubes relative to each other in response to operation of the drive source.

An electric powered self-balancing unicycle may include a single wheel assembly having a drive system substantially contained within the wheel, a frame and handlebars including a four-bar linkage mechanism pivotably connected to the wheel assembly by a fork.

A longitudinally adjustable assembly for a bicycle seat has a seat tube, a seat post and an auxiliary hoop device. The seat tube has an inner surface and multiple longitudinal grooves formed in the inner surface of the seat tube. The seat post is slidably inserted into the seat tube and has an outer surface and multiple protrusions. The protrusions are formed on and protrude out from the outer surface of the seat post. The protrusions are respectively slidably mounted in the longitudinal grooves to allow the seat post to longitudinally move along the seat tube. The auxiliary hoop device is mounted securely with the seat tube and around the seat post. Because the protrusions are slidably mounted in the longitudinal grooves and the auxiliary hoop device provides a pressing force for the seat post, a relative rotation between the seat post and the seat tube can be avoided.

A recess is defined in one of the top tube, the down tube and the seat tube of a bicycle frame and a power supply unit is engaged with the recess. The power supply unit includes an engaging frame engaged with the recess and a battery is removably engaged with a main space defined in the engaging frame. The engaging frame includes a chamber defined in an end thereof and a control box is received in the chamber so as to be electrically connected with the control box. The top surface of the battery is in flush with the one of the top tube, the down tube and the seat tube. An ON/OFF switch is installed on a top of the engaging frame and an indication bulb is installed on a top of the battery for convenience of observation by the user.
