[0002] The present invention relates to a bicycle actuation device.

[0003] Conventional mounting structures for bicycle bar-end shifters include expanders. Conventional bar-end shifters often require a cumbersome installation step involving inserting a bar-end shifter mounting structure into one end of the handlebar and then expanding the bar-end shifter's expander using a tool. Furthermore, with conventional bar-end shifters, it is difficult to route an electrical wire or a mechanical control wire through the center of the handlebar. Therefore, a user cannot freely rotate the bar-end shifter to position it in a preferred orientation. Conventional mounting structures for bicycle bar-end shifters are known from US 5,247,431 A, EP 2,657,121 A1, and CH 709,565 A2.

[0057] Firstly, referring to Fig. 1, a bicycle actuation device 10 is provided according to one embodiment of the present invention. A bicycle 1 is provided with a bicycle actuation device 10 comprising a mounting structure configured to be press-fitted to a free end 5b of the bicycle handlebar 5. Alternatively, the mounting structure can be configured to be press-fitted to a free end of an air rod 7 or any other attachment provided on the bicycle handlebar. The bicycle actuation device can be a brake / shift control device or other control devices that can effect the actuation of the bicycle or constitute parts of the brake and shift control system of the bicycle.Consequently, the bicycle actuation device 10 can be coupled to bicycle components such as a front derailleur 4a or a rear derailleur 4b, which are provided on a frame 6, to change gears on a front wheel 2a or a rear wheel 2b, respectively. Alternatively, the bicycle actuation device 10 can be coupled to a front brake 3a or a rear brake 3b of the bicycle 1, which are provided on the frame 6, to apply a braking force to a front wheel 2a or a rear wheel 2b, respectively. It should be noted that the bicycle actuation device 10 can also be coupled to other components of the bicycle 1, such as an electrically actuated bicycle suspension or an electrically actuated height-adjustable seat post, in other embodiments.

[0058] Referring to Fig. 2, a conventional handlebar end switch 212, which is mounted on a bicycle handlebar 5, is described. The conventional handlebar end switch 212 is provided with expansion links 242, which are coupled together by an expandable ring link 244. In this configuration, when the fixing bolt 240 is rotated to move towards the tapered contact surface 230b of the handlebar mounting section 230, the inclined surfaces of the fixing bolt 240 and the tapered contact surface 230b cooperate to move the expansion links 242 and the expandable ring link 244 radially outwards, thus securely mounting the handlebar end switch 212 in a position within the free end 5b of the handlebar 5. However, this mounting method is cumbersome for a user.This is time-consuming, as the user must use a tool to rotate the fixing bolt 240 after inserting the mounting structure into the free end 5b of the handlebar 5. Furthermore, with conventional handlebar end switches 212, an electrical wire or a mechanical control wire cannot be routed to the center of the handlebar because there is insufficient space to allow the electrical wire or control wire to pass through the center of the handlebar 5. Consequently, the user is unable to freely rotate the handlebar end switch 212 and position it in a preferred orientation.

[0059] Referring to the Fig. 3A and Fig. Figure 3B shows a bicycle actuation device having a central axis A according to the first embodiment of the present invention. Fig. Figure 3A illustrates a side view of the bicycle actuation device 10 from the same perspective angle of the bicycle handlebar 5 as in Figure 3. Fig. 2, while Fig. Figure 3B illustrates a longitudinal cross-sectional view of the bicycle actuation device 10. In this embodiment, the bicycle actuation device 10 comprises a mounting structure 12, which is configured to be press-fitted into a free end 5b of a bicycle handlebar 5 without the use of a tool, and comprises an actuation structure 14, which includes a housing element 30 for actuating a bicycle component 28 that is operatively coupled to the bicycle actuation device 10. In this embodiment, the housing element 30 of the actuation structure 14 can be coupled to the mounting structure 12 by clicking or snapping it into place, using a bolt fastener, welding, bonding, adhesives, and / or similar methods, and comprises a plastic or resin material. In the first embodiment, the length of the housing element 30 in an axial direction parallel to the central axis A is preferably less than 35 mm and more preferably 28 mm or less.Since the length of the housing element 30 is shorter than that of conventional handlebar-end shifters, it is difficult for the rider to grip the housing element 30 while cycling. Consequently, this requires the rider to grip the handlebar 5 rather than the housing element 30, thus reducing the load exerted on the housing element 30 by the rider. As described above, the bicycle component 28 can be any component of the bicycle, such as brakes or derailleurs, that is operatively coupled to the bicycle actuation device 10. Fig. 3A, Fig. 3B, Fig. 6A and Fig. 6B shows the bicycle component 28 as a rear derailleur, although other bicycle components such as a front derailleur, front brake or rear brake can be used.

[0060] Referring to Fig. 3B, the mounting structure 12 includes a retaining element 16, which comprises a plurality of retaining sections 18 designed to hold the mounting structure 12 in the free end 5b of the bicycle handlebar 5. The retaining element 16 is preferably made of a plastic or resin material such as polyamide, fiber-reinforced plastic, glass-reinforced plastic, and rubber, among others, or any other flexible material, such that the retaining element 16 is at least partially elastically deformable. The retaining element 16 preferably has an annular shape, but can be formed from any other shape that corresponds to the dimensions of the interior of the free end 5b of the bicycle handlebar 5. Fig. Figure 3B shows the dotted lines B and C illustrating the outer edge of the inner peripheral surface of the free end 5b of the bicycle handlebar 5, to which the retaining element 16 must be adapted to be press-fitted. According to this embodiment of the present invention, even if the lengths of the individual retaining sections 1 exceed the dimensions of the interior of the bicycle handlebar 5, as outlined by the dotted lines B and C, the retaining element 16 is designed to deform when the mounting structure 12 is press-fitted into the free end 5b of the bicycle handlebar 5. To further facilitate the deformation of the retaining sections 18, the plurality of retaining sections 18 are arranged along an axial direction parallel to the central axis A such that a section or gap is formed between the adjacent retaining sections 18, thereby providing even more space for deformation.Furthermore, the radial tip of the retaining member 16 is deformed by the press fit of the mounting structure 12 such that the force required for the press fit into the free end 5b of the bicycle handlebar 5 is less than the force required to remove the mounting structure 12 from the free end 5b of the bicycle handlebar 5.

[0061] Referring further to Fig. 3B, the assembly structure 12 further includes a shaft member 22, which is configured to extend from the actuating structure 14 in an axial direction parallel to the central axis A, and the retaining member 16 extends radially away from the central axis A from the shaft member 22. It should be noted that the lengths of the plurality of retaining sections 18 may differ from one another in a radial direction (some may be longer than others in the radial direction if they deform elastically during the press fit). Alternatively, the lengths of the plurality of retaining sections 18 may be equal to one another in the radial direction. The retaining member 16 also includes a support section 20, which is arranged between the retaining member 18 and the actuating structure 14 in the axial direction, and the axial length of the support section 20 is greater than the axial length of the retaining section 18.According to this embodiment of the present invention, the support section 20 is arranged to provide stability to the mounting structure 12 against an actuating force applied by the rider to actuate the actuating structure 14. Furthermore, the axial lengths of the retaining member 16 and the housing member 30 are designed in the direction of the central axis A such that the latter is shorter than or equal to the former. In other words, if the actuating structure 14 includes a housing member 30 having a second axial length X2 in the direction of the central axis A, and the retaining member 16 has a first axial length X1 in a direction of the central axis A, the second axial length X2 is shorter than or equal to the first axial length X1. This provides stable support for the bicycle actuating device 10 when it is press-fitted into the bicycle handlebar 5, since, in particular, the mounting structure 12 is not fixed by a fastener such as a bolt.However, in other embodiments, the first axial length X1 can be shorter than or equal to the second axial length X2. The shaft member 22 further includes a through-hole 24, which extends along the axial direction parallel to the central axis A of the actuating structure 14. The central axis A passes through the through-hole 24, within which an electrical cable 26 is / will be arranged. Since the central axis A passes through the through-hole, the angular position of the bicycle actuating device 10 with respect to the handlebar 5 is not restricted by the electrical cable 26, which runs through the through-hole 24.Furthermore, it is easy to adjust the angular position of the bicycle actuation device 10 with respect to the handlebar 5 with respect to the central axis A, since the mounting structure 12 is not fixed by a fastener such as a bolt, but is simply press-fitted into the free end 5b of the bicycle handlebar 5 without a tool.

[0062] As in Fig. As shown in Figure 3B, the actuating structure 14 includes an electrical switching unit 32, which is configured to output a signal to actuate the bicycle component 28, and an electrical cable 26, which is electrically connected to the electrical switching unit 32, the electrical cable 26 being arranged within the through-hole 24. To support the electrical switching unit 32, the mounting structure 12 includes a switching unit support element 38, which is at least partially located within the actuating structure 14 (see Figure 3B). Fig. 4A-B (for alternative perspective views, the housing member 30 and the electrical switching unit 32 are shown removed for clarity). Normally, in the first embodiment, the electrical switching unit 32 is arranged outside the bicycle handlebar 5. However, alternatively or additionally, the electrical switching unit 32 can be supported by a switching unit support member 38, which is arranged at least partially within the actuating structure 14, such that at least a part of the electrical switching unit 32 is arranged within the bicycle handlebar 5, in a state where the mounting structure 12 is press-fitted into the free end 5b of the bicycle handlebar 5. This consequently allows the length of the housing member 30 to be shorter. The switching unit support member 38 can be incorporated into the mounting structure 12 and be formed integrally with the shaft member 22 and the retaining member 16.In this embodiment, the switching unit support member 38 is arranged adjacent to the inlet opening 40, into which the electrical cable 26, which is electrically connected to the electrical switching unit 32, is inserted (see . Fig. 4A-B). At least one part of the electrical switching unit 32 is arranged in the housing element 30, which comprises at least one part of a peripheral surface of the actuating structure 14. The peripheral surface of the actuating structure 14 is essentially axially symmetric with respect to the central axis A, such that every cross-section of the peripheral surface of the actuating structure 14 that is perpendicular to the central axis A is essentially a circle. The peripheral surface may be tapered in an axial direction parallel to the central axis A.

[0063] Referring to Fig. 4A, the mounting structure 12 can further include an additional retaining element 42, which is attached to the retaining element 16, as indicated by the black arrow, or detachably attached. The additional retaining element 42 can be a plastic or resin plate made of plastic or flexible plastic material, around which the retaining element 16 is wound to adjust the press fit between the handlebar 5 and the mounting structure 12. The additional retaining element 42 is designed to adjust the diameter of the mounting structure 12. The additional retaining element 42 is also designed to adjust friction between the mounting structure 12 and the inner peripheral surface of the free end 5b of the bicycle handlebar 5. Accordingly, the mounting structure 12 can be designed to be press-fitted into a free end 5b of a bicycle handlebar 5 with a different inner diameter. The dimensions, orThe dimensions of the additional retaining element 42 are not particularly limited and can be provided in a tubular or tube-shaped form, or as a spacer, a strip, a plate, or the like. A power supply 44 can be included in the actuating structure 14, designed to provide electrical current to the electrical switching unit 32 to transmit the wireless signal via the wireless transmitter 36, as shown in the figure. Fig. 5B, to transmit, consequently to prevent the need to design power cables that supply the electrical current outside the actuating structure 14. Alternatively, the power supply can be designed to be located in the mounting structure 12 or outside the bicycle actuating device 10, instead of being located in the actuating device 14, in order to reduce the dimensions of the actuating structure 14. Furthermore, the power supply can be a battery (e.g., a rechargeable battery or a solar battery) or an electrical generator (e.g., piezoelectric elements).

[0064] Referring to the Fig. 5A and Fig. 5B, the electrical switching unit 32 includes a user actuation element 34, which forms part of the peripheral surface of the actuation structure 14. The user actuation element 34 can be further designed to be actuated in a direction other than the central axis A, thereby making the electrical switching unit more easily accessible for actuation by the user's fingers when the handlebar is gripped. More specifically, the user actuation element is actuated in a direction towards the central axis A. Alternatively or additionally, a wireless transmitter 36 can be further included in the electrical switching unit 32, designed to transmit a wireless signal to actuate the bicycle component 28, thus eliminating the need for an electrical cable communicating with the bicycle component.It should be noted that the user actuation element 34 does not protrude from the peripheral area of ​​the actuation structure 14. This is to prevent the electrical switching unit 32 from being accidentally activated or actuated.

[0065] Referring to the Fig. 6A and Fig. Figure 6B, comprising a bicycle actuation device 110 and a central axis A, is shown according to a second embodiment of the present invention. Since the structure of the second embodiment is essentially the same as that of the first embodiment, a detailed description thereof is omitted here for the sake of brevity. It should be understood that similar parts are identified by the same reference numerals, by the detailed description, and by the accompanying drawings. Fig. Figure 6A illustrates a side view of the bicycle actuation device 10 from the same viewpoint as the bicycle handlebar 5, as shown in the Fig. 2 and Fig. 3A, while Fig. Figure 6B illustrates a longitudinal cross-sectional view of the bicycle actuation device 110. In this embodiment, a mounting structure 112 is configured to be mounted in a free end 5b of a bicycle handlebar 5. The actuation structure 114 includes an electrical switching unit 132, which is configured to output a signal to actuate a bicycle component 28, wherein the actuation structure 114 is coupled to the mounting structure 112.

[0066] Unlike the illustrated configuration of the first embodiment, at least a part of the electrical switching unit 132 is arranged within the bicycle handlebar 5 in a state in which the mounting structure 112 is / will be mounted in the free end 5a of a bicycle handlebar 5. Accordingly, the retaining member 116 of the second embodiment does not require a support section arranged axially between the retaining space 118 and the actuating structure 114 to reinforce the mounting structure 112, since a section of the actuating structure 114 serves as a support section. It should be noted that in the illustrated configuration of the second embodiment, the electrical cable 126 is / will not be arranged in a through-hole of a shaft member.Rather, in the illustrated configuration, the electrical cable 126 is arranged outside the mounting structure 112 and the bicycle handlebar 5, with the electrical cable 126 being represented as a fixed line in the . Fig. 6A and Fig. 6B is described. However, in an alternative configuration of the second embodiment, the electrical cable 126 can be configured as in the first embodiment, namely arranged in a through-hole of a shaft member 122 and inside the bicycle handlebar 5, the electrical cable 126 being shown in a dashed line in Fig. 6A is described. It should be understood that in the second embodiment, the second axial length X2 of the housing member 130 is much shorter than the first axial length X1 of the retaining member 116 in order to provide improved support for the bicycle actuation device 110 when it is press-fitted into the bicycle handlebar 5.

[0067] Referring to Fig. Figure 7 shows the mounting structure 112 and the actuating structure 114 of the second embodiment, with the electrical switching unit, the user actuating element, and the housing element removed for clarity. Unlike the first embodiment, the second embodiment does not include an inlet opening into which the electrical cable 126, which is electrically connected to the electrical switching unit, is inserted. Instead, the electrical cable is inserted into a cutout section 140 provided on a lateral wall of the actuating structure 114, such that the electrical cable 126 is located outside the mounting structure 112 and the bicycle handlebar 5.However, in other configurations of the second embodiment, the electrical cable 126 can be designed similarly to the first embodiment to be inserted into an inlet opening and arranged within the bicycle handlebar 5b. Furthermore, the switching unit support element 138 is designed to support the electrical switching unit adjacent to the cutout section 140, such that an electrical cable 126, which is electrically connected to the electrical switching unit, extends from the actuating structure 114 to be arranged outside the mounting structure 112 and the bicycle handlebar 5.

[0068] Referring to the Fig. 8A - C, are an electrical switching unit 132 and a user actuating element 134 of the second embodiment shown together with a housing element 130. In Fig. 8A shows the user actuation element 134 of the electrical switching unit 132 separately from the housing element 130. Fig. Figure 8B shows the housing element 130 in isolation. Fig. Figure 8C shows the housing element 130 and the user actuation element 134 of the electrical switching unit 132 when assembled or mounted together as a single actuation structure 114. According to the second embodiment, the user actuation element 134 is configured to be actuated in an axial direction parallel to the central axis A, with the user actuation element 134 forming part of the peripheral surface of the actuation structure. The housing element 130 is configured as a torus or ring shape with an inner diameter that fits the shape of the exposed surface of the user actuation element 134, and an outer diameter is configured to contact and cover substantially the entire edge and outer diameter of the bicycle handlebar 5 when the bicycle actuation device 110 is press-fitted into the bicycle handlebar 5.In the second embodiment, the length of the housing member 130 in an axial direction parallel to the central axis A is preferably less than 35 mm and more preferably 5 mm or less. Alternatively, the length can assume other suitable dimensions. Compared to the first embodiment, the first axial length X1 of the retaining member 116 is substantially longer than the second axial length X2 of the housing member to provide improved support for the bicycle actuation device 110 within the bicycle handlebar 5. It should be noted that, notwithstanding the shortened length of the housing member 130 compared to the first embodiment, the peripheral surface of the actuation structure 114 is still tapered in an axial direction parallel to the central axis A. It should also be understood that the electrical switching unit 132 includes a user actuation element 134, which forms part of the peripheral surface of the actuation structure 114.The user actuation element 134 can be further designed to be actuated in a direction parallel to the central axis A. More specifically, the user actuation element 134 can be further designed to be actuated towards the free end 5b of the bicycle handlebar 5. This enables stable support of the bicycle actuation device 10 when the user actuation element 134 is actuated by a user's finger.

[0069] Referring to the Fig. 9A and Fig. Figure 9B shows a bicycle actuation device 310 comprising a central axis A according to a third embodiment of the present invention. Since the structure of the third embodiment is essentially the same as that of the first and second embodiments, a detailed description thereof is omitted here for the sake of brevity. It should be understood that similar parts with the same reference numerals are identified throughout the detailed description and the accompanying drawings. Fig. Figure 9A illustrates a side view of the bicycle actuation device 310 from the same viewpoint of the bicycle handlebar 5 as in the Fig. 2, Fig. 3A and Fig. 6A, while Fig. Figure 9B illustrates a longitudinal cross-sectional view of the bicycle actuation device 310. In this embodiment, the mounting structure 312, which is mounted in a free end 5b of a bicycle handlebar 5, has a retaining element 316 with a plurality of tapered, wedge-shaped retaining sections 318. The actuation structure 314 includes a curved user actuation element 334, which is coupled to a curved housing element 330. An electrical cable 326 runs along the central axis A of the bicycle handlebar 5 and the bicycle actuation device 310 to electrically connect the electrical switching unit 332 to a bicycle component 28. In this embodiment, the length of the housing element 330 in an axial direction parallel to the central axis A is preferably 13 mm or less.Similar to the second embodiment, if the first axial length X1 in a direction of the central axis A is defined as the length of the retaining member 316, and the second axial length X2 in the direction of the central axis A is defined as the length of the actuating structure 314, the second axial length X2 is shorter than or equal to the first axial length X1, in order to thereby provide stable support for the bicycle actuating device 310 when it is press-fitted into the bicycle handlebar 5.

[0070] Referring to Fig. 9B, the user actuator 334 is pivotally attached to the mounting structure 312 and a housing element 330 of the actuator structure 314 about a pivot axis D, which is substantially perpendicular to the central axis A. The central axis A bisects or intersects the user actuator 334. In this view, the housing element 330 has been omitted for clarity. The electrical switching unit 332 includes a button 335, which is located on the opposite side of the central axis A from the pivot axis D when viewed from an axial direction of the pivot axis D. The user actuator 334 has a curved or bent shape when viewed from an axial direction of the central axis A. The pivot axis D is located at one end of the mounting structure 312 and the housing element 330.The user actuation element 334 extends from the pivot axis D to the other end of the mounting structure 312 and the housing element 330 when viewed from an axial direction of the pivot axis D. A printed circuit board or switch board 337, which is electrically connected to the electrical cable connector 317 by an electrical cable 326, is provided adjacent to the button 335 within the electrical switching unit 332 to output a signal to actuate the bicycle component 28. The electrical cable connector 317, which is electrically connected to the bicycle component 28 by the electrical cable 326, has a recess 317b or notch that accommodates a restraint part 321, which is included in the mounting structure 312, to hold the electrical cable connector 317 in place and limit its axial movement.On the other hand, the electrical cable connector 317 can allow free radial movement of the electrical cable 326 to prevent cable tension.

[0071] For example, when a user operates the bicycle control device 310 by pressing against the user control element 334, the user control element 334 moves about a pivot point 323, which defines the pivot axis D, and presses the button 335 downwards, thereby activating the electrical switching unit 332. In response, the switch board 337 within the electrical switching unit 332 outputs a signal that is conducted along the electrical cable 326 through the electrical cable connector 317 to the bicycle component 28, which receives the signal. It should be noted that the pivot point 323 and / or the button 335 may be equipped with a spring or other elastic mechanisms that generate resistance when the user presses against the user control element 334 and the button 335.

[0072] Referring to the Fig. In Figures 9B and C, the mounting structure 312 includes a retaining element 316, which comprises a plurality of retaining sections 318 configured in a wedge shape to hold the mounting structure 312 in the free end 5b of the bicycle handlebar 5. Since the bicycle handlebar 5 can have different diameters, the retaining element 316 is selected from a plurality of differently dimensioned retaining elements, each with a different outer diameter. Accordingly, a user can select a retaining element with an outer diameter that is the appropriate size for the bicycle handlebar 5. Similar to the first and second embodiments, the retaining element 316 is at least partially elastically deformable such that it deforms when the mounting structure 312 is press-fitted into the free end 5b of the bicycle handlebar 5 to accommodate its diameter.The wedge-shaped forms are achieved by tapering at least one of the plurality of retaining sections 318 in an axial direction parallel to the central axis such that the diameter of each retaining section 318 decreases as it extends away from the actuating structure 314. Specifically, at least one of the plurality of retaining sections 318 includes a first outer periphery with a first outer diameter and a second outer periphery with a second outer diameter. The first outer diameter is smaller than the second outer diameter, and the second outer periphery is positioned closer to the actuating structure 314 than the first outer periphery. Accordingly, the force required to remove the bicycle actuating device 310 from the bicycle handlebar 5 is greater than the force required to press it into it.The retaining element 316 can also include a non-tapered support section 320, which is / will be arranged in the axial direction between the retaining section 318 and the actuating structure 314.

[0073] Referring to Fig. Figure 11 shows an open cross-sectional view of the mounting structure 312 of the third embodiment of the invention, revealing the interior of the mounting structure 312, which includes an electrical connector holder 319 that supports the electrical cable connector where the electrical cable connector (not shown) engages or snaps into the electrical connector holder 319. The electrical cable connector and the electrical cable have been removed from this view for clarity. In this embodiment, the mounting structure 312 includes a shaft member 322 with a retaining section 318, which is formed on an outer surface 322b of the shaft member 322. The electrical connector holder 319 is formed on an inner surface 322a of the shaft member 322.The electrical connector holder 319 is designed as a two-stage projection and one of the projections is a restraint part 321 which engages with / reaches the electrical cable connector and restricts its axial movement to prevent it from sliding towards or away from the user actuating element 334.

[0074] As in Fig. As illustrated in Figure 11, it should be noted that the retaining element 316 is a separate element from the shaft element 322 and is designed to be detachably attached to the shaft element 322. Viewed from the axial direction of the central axis A, the shaft element 322 forms a hollow cylinder with an outer circumference forming the outer surface 322b and a cavity with an inner circumference forming the inner surface 322a, within which the electrical cable connector is accommodated. The inner surface of the retaining element 316 directly contacts an interface with the outer circumference of the shaft element 322 and forms it to cover substantially the entire outer surface 322b of the shaft element 322.The materials comprising the retaining element 316 and the shaft element 322 are selected to achieve a preferred coefficient of friction between the two materials. This coefficient is not so high as to prevent the user from easily loosening the retaining element 316 to replace it with a retaining element of a different size, but also not so low as to cause the retaining element 316 to easily slide off the shaft element 322 during normal use. Furthermore, the outer surface 322b of the shaft element 322 and the inner surface of the retaining element 316 can undergo a surface roughening treatment to further adjust the coefficient of friction.

[0075] Referring to Fig.Figure 12 shows a bicycle mounting structure 412 according to a fourth embodiment of the present invention. Since the structure of the fourth embodiment is essentially the same as that of the third embodiment, a detailed description thereof is omitted here for the sake of brevity. The mounting structure 412 can further include at least one additional retaining element 442, which is attached or detachably attached to the retaining element 416. In this embodiment, the additional retaining element 442 includes a plurality of elastic rings that are provided between the retaining sections 418. The shape of each retaining section 418 can be modified such that at least a part of the surface is substantially parallel to the central axis of the mounting structure 412, with each retaining section 418 defining a gap or space or slot that accommodates an additional retaining element 442.The additional retaining element 442 can include an elastic ring made of plastic or flexible plastic, and the elastic ring can be designed as a U-ring. Accordingly, when the user press-fits the mounting structure 412 into the bicycle handlebar 5, the retaining element 416 and the additional retaining element 442 deform to accommodate the diameter of the handlebar 5. Compared to the second and third embodiments, the mounting structure 412 can provide additional contact points with the inside of the handlebar 5 to improve friction and adhesion. Furthermore, by selecting the attachment method of the additional retaining element 442, it is possible to select an outer diameter of the mounting structure 412 corresponding to the outer diameter of the handlebar 5 into which the mounting structure 412 is press-fitted. The releasable orRemovable additional retaining link 442 can be designed to be selected from / included additional retaining links of different dimensions.

[0076] In the present embodiments, a bicycle actuation device is mounted to one end of a handlebar by means of a press fit. This offers the potential advantage that the bicycle actuation device can be mounted to the handlebar quickly and easily. According to the present invention, a user can freely rotate the actuation device to position it in a preferred orientation. Furthermore, since expanders are not required, the bicycle actuation device can be lighter than conventional models.
