A bicycle derailleur is basically provided with a base member, a movable member, a link structure and a cable interactive structure. The link structure is configured to movably connect the movable member relative to the base member. The cable interactive structure is provided on the link structure. The cable interactive structure includes a chain barrier portion. The chain barrier portion is configured to prevent a chain from contacting the link structure.

The present disclosure relates to devices and methods of converting a bicycle frame from a mechanical gear-shifting configuration to an electronic gear-shifting configuration and vice versa. In a representative embodiment, a method of converting a bicycle frame from a mechanical gear-shifting configuration to an electronic gear-shifting configuration comprises removing a mechanical cable extending between a mechanical gear-shift actuator and a mechanical gear shifter via a cable stop of a removable bracket member secured to a down tube member of the bicycle frame, and removing the removable bracket member from the down tube member of the bicycle frame. The method further comprises mounting an electronically-actuated gear shifter to the bicycle frame in electrical communication with an electronic gear-shift actuator such that actuation of the electronic gear-shift actuator causes the electronically-actuated gear shifter to shift gears.

A front fork for a bicycle is disclosed. The bicycle includes a handlebar, a stem, a headset, a frame and the front fork. The frame has a top tube, a down tube and a hollow head tube, and the stem secures the handlebar to the front fork via the headset such that movement of the handlebar results in movement of the stem and the front fork. The front fork comprises a pair of hollow tubular fork legs and a hollow steerer tube connected to the pair of hollow tubular fork legs and has a first opening formed thereon. Wherein the hollow head tube has a second opening formed thereon and corresponding and communicating to the first opening of the hollow steerer tube when the hollow steerer tube of the front fork is secured to the stem through the hollow head tube.

A bicycle gearshift mechanism has a base element, a pivot mechanism, a movable element, and a chain guide arrangement. The pivot mechanism connects the base element to the movable element. The chain guide arrangement is connected, rotatably about a rotary axle, to the movable element. The base element comprises a first attachment end, which is coaxial with respect to the rear-wheel axle or axis, and a second attachment end for coupling to the pivot mechanism

A bicycle gear shifter that has a control pin and a cable-winding bush mounted coaxially and rotatable in opposite angular directions. A ball-carrying bush is mounted coaxially for rotation as a unit with the cable-winding bush and is equipped with at least one slider. An indexing bush is rotatable with respect to the control pin is provided with a plurality of stop positions engageable during a relative rotation between the ball-carrying bush and the indexing bush, each stop position defining a stable angular position for the cable-winding bush. A pointer is switchable between an active position in which it interacts with the indexing bush to limit the angular play thereof with respect to the casing and a passive position in which it does not interact with the indexing bush and does not limit the angular position between the indexing bush and the casing.

A cycle includes steering handles having one or more of a brake controller, a gear shifter, a throttle, and/or an electronic display. The cables for one or all of these components are inside the steering handle in the area adjacent to the hand grip of the steering handle. The brake controller can be used to simultaneously activate two or more brake assemblies. The cycle can be any suitable cycle such as a bicycle or a tadpole tricycle.

A bicycle wireless electronic derailleur, comprising a support body, a movable body, comprising a chain guide, actuation means configured to move the movable body with respect to the support body, comprising an electric motor, a controller of the electric motor, a wireless communication device, part of or in communication with the controller, configured to receive gearshifting request signals from a wireless transmitter and housed in a first casing, and a bicycle movement detector configured to emit a wake signal for the wireless communication device. The movement detector is at least partially housed in at least one second casing different from the first casing, and is in communication through at least one cable with the wireless communication device.
