Abstract: An electrical switch apparatus for a bicycle control device comprises a mounting member structured to be mounted to a bicycle, an operating member supported by the mounting member for movement between an operating member start position and an operating member operating position, a first piezoelectric element supported by the mounting member, and a first striking member supported by the mounting member for movement between a first striking member start position and a first striking member striking position. The first striking member is operatively coupled to the first operating member such that the first striking member moves from the first striking member start position to the first striking member striking position to strike the first piezoelectric element in response to movement of the first operating member from the first operating member start position to the first operating member operating position.

Abstract: A cable winding conversion device is provided that enables relatively easy placement on a frame such as a bicycle frame between a pair of cables. The cable winding conversion device basically includes a base member, a first winder, a second winder, a first cable mounting portion, and a second cable mounting portion. The base member is configured to be mounted to a frame. The first and second winders are rotatably mounted to the base member to wind first and second inner wires of the first and second cables. The second winder has at least a portion with a winding radius larger than the first winder. The first cable mounting portion directs the first cable. The second cable mounting portion directs the second cable. The second cable mounting portion includes a cable receiving opening that is directed toward a rotation center of the winders.

Abstract: A bicycle headset has an adjustment member and a fastening member. A bicycle fork column passes through the adjustment member and the fastening member. The fastening member is fastened securely to the bicycle fork column by applying pressure to the outer peripheral side of the bicycle fork column. The fastening member non-rotatably mates with the adjustment member in such a way so as to move freely in the axial direction of the bicycle fork column.

Abstract: A bicycle gearshift system is mounted on the rear part of the frame of the bicycle. The bicycle gearshift system includes an electrically powered rear derailleur, a rear hub, a charger part, and a gearshift control part. The electrically powered rear derailleur is mounted on the rear part of the frame. The rear hub is also mounted to the rear part of the frame. The rear hub has an electrical generator mechanism that generates electricity through the rotation of the wheel. The charger part is mounted on the rear hub and stores the electrical energy that was generated by the generator part. The gearshift control part is equipped on the electrically powered rear derailleur, where gearshift control of the electrically powered rear derailleur is performed through the energy that is stored in the charger part.

Abstract: A bicycle headset structure is provided to aid in concealment of wiring from components mounted in the handlebar area to components mounted on the rest of the bicycle. The bicycle headset structure basically comprises a handlebar attachment member and a tubular spacer member. The handlebar attachment member has wiring passage extends between the handlebar mounting portion and the steerer tube attachment portion. The tubular spacer member has a wiring channel extending between first and second ends of the tubular spacer member and an axial passageway extending axially between the upper and lower end openings of the tubular spacer member. The axial passageway is dimensioned to receive the bicycle steerer tube. The wiring channel is arranged to communicate with the wiring passage of handlebar attachment member when the handlebar attachment member and the tubular spacer member are attached to the bicycle steerer tube.

Abstract: An electrical switch or operating device is disclosed for controlling/operating an electrically controlled bicycle component. In one embodiment, the operating device controls/operates a bicycle shift device and a bicycle suspension. The operating device has a base portion, a toggle portion, a button portion, three electrical contact switches, and a clicking mechanism. The clicking mechanism is positioned in a manner to provide for a compact arrangement of the operating device. The toggle portion is pivotally mounted to the base portion to move from a toggle neutral position to first or second contact positions where the toggle portion depresses either the first or electrical contact switches. The button portion is movably coupled to the toggle portion between a button neutral position where the button portion is spaced from the third electrical contact switch and a third contact position where the button portion depresses the third electrical contact switch.
