A liftable seatpost includes an outer tube, an inner tube, and a bushing. A protrusion is provided at the outer surface of the inner tube. The bushing is disposed between the inner and outer tubes and includes an upper sleeve and a lower sleeve. The upper sleeve has an upper baffle ring with a first engaging portion. The lower sleeve has a lower baffle ring with a second engaging portion engaged with the first engaging portion of the upper sleeve. The edges of the upper and lower sleeves are abutted against each other, and the outer surface of the upper baffle ring is flushed with the outer surface of the lower baffle ring. Thus, the position corresponding to the bushing will not protrude too much and affect the appearance, and the stress transmitted from the protrusion of the inner tube to the upper sleeve can be effectively distributed.

There is provided a straddle-type vehicle, including: a pair of seat frames; a seat; an air cleaner; a battery; and a bracket. A rear portion of the air cleaner and the battery are positioned below the seat. The battery is disposed above the rear portion of the air cleaner. The bracket extends in a left-right direction of the straddle-type vehicle and passes between the rear portion of the air cleaner and the battery. A left end side and a right end side of the bracket are connected to the pair of seat frames respectively. The rear portion of the air cleaner is suspended by the bracket. The battery is installed on the bracket.

A bicycle seatpost system comprises an electric actuator, a remote controller, and a seatpost controller. The seatpost controller is configured to control the electric actuator to change a state of the bicycle seatpost assembly to an adjustable state based on one of a first control signal and a second control signal. The remote controller includes a first operating part configured to receive a first user input and a second operating part configured to receive a second user input. The remote controller is configured to generate the first control signal having a constant signal length regardless of an operation period of the first user input. The remote controller is configured to generate the second control signal having a signal length corresponding to the operation period of the second user input.

A telescopic apparatus comprises a first tube, a second tube, and a non-contact detector. The second tube is configured to be telescopically received in the first tube. The non-contact detector is provided inside at least one of the first tube and the second tube configured to detect a position of the second tube relative to the first tube.

Embodiments of the invention provide a customizable bicycle saddle for a bicycle. The bicycle saddle has been designed to allow it to be adjusted to match the ischial tuberosities of each rider's pelvis in order to minimize the pressure placed on other portions of the rider's body while seated on the bicycle. The bicycle saddle comprises a first seating portion that has been configured to allow a rider to sit on the bicycle, a second seating portion that has been configured to allow the rider to sit on the bicycle. The bicycle saddle also includes a first adjustment means configured to allow the first seating portion to be moved closer to the second seating portion, and a second adjustment means configured to allow the saddle to be moved closer to a forward portion on the bicycle.

The present invention relates to a seat for providing of a seat for a person on a bicycle, including an optional support assembly for mounting of the title to the bicycle, such as including a support member for supporting by the support assembly of a seat assembly. The support member is preferably mountable or fastened to a saddle pin. The seat assembly includes a support element, fixation means for fixation of the seat assembly to the support member, buffer means, supported by the support element, for providing of a buffering all forces between the bicycle and the person, and a seat surface defined by the upper side of the buffer means. The support element provides a substantially rigid support supporting the buffer means relative to the support member, the support element in top view substantially defines the shape of this support, and the support element is arrangeable on the support member.
