A bicycle control device includes an electronic controller configured to control an operational state of an electric auxiliary drive to a manual drive driving force inputted to the bicycle. The electric auxiliary drive assists in travel of a bicycle based on an operational state of a suspension of the bicycle. The electronic controller controls the operational state so that the bicycle is assisted at an assist ratio of the electric auxiliary drive.

A bicycle component includes a base member, a movable member, a link member, an actuator, and a battery holder. The link member movably couples the movable member to the base member. The actuator is operatively coupled to the link member to move the link member. The battery holder is detachably attached to the link member. The battery holder includes a battery holding portion configured to hold a battery and a flexible element electrically connecting the battery holding portion to the actuator.

A bicycle saddle with an ischial-perineal suspension region may include a monolithic frame, a flexible lamina stretched across and attached to the frame, a cushion on the lamina, and a cover over the cushion. The frame may include a mounting rail configured to attach to a seat post of a bicycle, a seat rail, a nose, and an open region circumscribed by the seat rail and the nose. The seat rail may include a rear rail that forms an arc-shape, a first side rail that forms a first trough, and a second side rail that forms a second trough. The nose may extend from the seat rail and/or the mounting rail. The open region may be an ischial-perineal suspension region. The flexible lamina may be stretched over the open region. The cushion may be disposed on the lamina over the open region.

The present invention aims to provide a variable damper seat post, which comprises: a damper base provided at an upper end portion of a post; a seat connecting body disposed on the damper base of the post and coupled to a seat on which buttocks of a passenger are seated; a fixing unit for fixing the seat connecting body to the damper base; and a damper, interposed between the damper base and the seat connecting body, for varying positions of the seat depending on the movement of the buttocks on the seat, wherein the damper is composed of an elastic member that is pressed when a pressing force is applied and returns back to its original shape when the pressing force is released, and is interposed between the damper base and the seat connecting body.
