An operating system comprises a first operating device, a second operating device, a first user interface, a second user interface, and a controller. The first user interface is configured to receive a first user input. The second user interface is configured to receive a second user input. At least one of the first user interface and the second user interface is configured to be operated to control at least one electric component. The controller is configured to control the at least one electric component based on at least one of the first user input and the second user input. The at least one electric component includes at least one of a gear changing unit, a gear changing unit, an adjustable seatpost, an internal gear hub, a front suspension, a rear suspension, a cycle computer, a smartphone, a tablet computer, and a light emitting device.

A bicycle seat post isolator assembly constructed to be fixedly engaged in a seat post receiving opening in a bicycle frame. A seat post gripper includes an elongated inner tubular body with an outer elastomeric layer/covering, inserted into the opening to receive a seat post coaxially therein. The layer/covering is positioned between the body and the bicycle frame. A retaining structure designed to be fixed adjacent an edge of the seat post receiving opening with a portion extending into the opening to only engage portions of the outer elastomeric layer/covering of the seat post gripper so as to lock the seat post gripper in the seat post receiving opening, whereby the layer/covering of the gripper is positioned between the body of the gripper with the seat post inserted coaxially into the gripper and the bicycle frame.

There is described a bicycle seat post assembly in which the travel distance of the seat post can be adjusted. The seat post assembly includes an outer tube that is configured to telescopically receive an inner tube. The inner tube is axially slidable relative to the outer tube between a retracted position and an extended position, the extended position being determined by an extension assembly in which an inner contact member engages an outer contact member, thereby setting the upper limit of axial extension of the inner tube. The extension of the inner tube can be limited to an intermediate position that lies between the retracted and extended positions by an insertable shim that is positionable between the inner and outer contact members.

A bicycle comprises front and rear wheels, a frame supported on the front and rear wheels and including a frame mount, and a battery including a battery mount engaged with the frame mount. One of the battery mount and the frame mount includes a depression and the other of the battery mount and the frame mount includes a boss positioned in the depression. Preferably, depression comprises a slot, and the slot can include a resilient material to securely hold the boss. The boss can comprise an eccentric boss. Preferably, the battery mount is positioned adjacent one end of the battery, and an opposite end of the battery includes an opening. In this embodiment, the bicycle further comprises a mounting pin positioned through the opening and through a portion of the frame to secure the opposite end of the battery to the frame.
