Description

[0001] The present invention relates to a bicycle component and a fastening structure for a bicycle component.

[0002] An example of a well-known bicycle component is a drive unit with a motor that assists the propulsion of a bicycle.

[0003] An example of such a drive unit is disclosed in DE 10 2016 12 778 A1. The drive unit, as an example of a bicycle component, comprises a housing that rotatably supports a crankshaft, a first fastening element provided on the housing and which can be attached to the bracket, and an adjusting element, at least a section of which is arranged in a gap between the first fastening element and the bracket, in a state in which the first fastening element is attached to the bracket.

[0004] Another example of a drive unit is disclosed in DE 20 2013 105 071 U1. The drive unit comprises a bottom bracket housing with an inner circumference, a housing, a crankshaft, an electric motor, a gearbox, and an output element, wherein the motor-gearbox bottom bracket unit is inserted or can be inserted into the bottom bracket housing such that the bottom bracket housing surrounds the housing of the motor-gearbox bottom bracket unit. At least one retaining element is arranged between the housing of the motor-gearbox bottom bracket unit and the bottom bracket housing, which presses with a first surface against an outer surface on the outer circumference of the housing of the motor-gearbox bottom bracket unit and with a second surface against an inner surface on the inner circumference of the bottom bracket housing.

[0005] Another example of a drive unit is disclosed in the republished US 2017 / 0314593 A1. The drive unit includes a housing with a first and a second suspension bolt, positioned between a first and a second side plate of the mount in the left-right direction of a bicycle. A first bolt is attached to the first suspension bolt and is inserted from the outside, in the left-right direction of the bicycle, into an opening in the first side plate. A cylindrical element is inserted into an insertion hole in the second suspension bushing, which is open toward the second side plate. The cylindrical element is displaceable in the left-right direction of the bicycle and includes a thread on its inner circumference that engages with a thread on the outer circumference of a second bolt, which is inserted from the outside, in the left-right direction of the bicycle, into an opening in the second side plate.

[0006] As another example of a drive unit, JP 4 416 620 B2 describes a motor unit with a mounting section that allows attachment to a bracket on a bicycle frame. The mounting section is inserted between two side plates of the bracket. The side plates and the mounting section are fastened with screws to secure the motor unit to the bracket.

[0007] Due to manufacturing tolerances, gaps can form between the side plates and the mounting section of the motor unit described above, which are secured by the screws. In this case, the motor unit may rattle against the two side plates when the bicycle is in motion.

[0008] One objective of the present invention is to provide a bicycle component that can be stably attached to a frame, and a mounting structure for the bicycle component.

[0009] A bicycle component according to the present invention comprises the features of claim 1.

[0010] This ensures the bicycle component is stably mounted to the frame. The first and second elements exert a force in a direction that preferentially moves the housing and the frame away from each other. The first element is connected to the second element and moved in such a way that the first end face of the first element presses against the housing. Advantageously, this provides preferential support for the housing from the first element.

[0011] According to a further preferred aspect of the present invention, the bicycle component can be designed such that the first element has a first bore extending in the first direction, and the housing has an insertion section inserted into the first bore of the first element. The insertion section of the housing is inserted into the first bore of the first element, so that the first element supports the housing.

[0012] According to a further preferred aspect of the present invention, the bicycle component can be designed such that the housing has a second bore extending in the first direction, and the first element has an end in the first direction that is inserted into the second bore. Thus, the end of the first element is inserted into the second bore of the housing, so that the first element supports the housing.

[0013] According to a further preferred aspect of the present invention, the bicycle component can be designed such that at least part of the second element is provided between the housing and the frame. In this way, the second element connects the housing stably to the frame.

[0014] According to a further preferred aspect of the present invention, the bicycle component can be designed such that at least part of the second element is provided between the first element and the frame. In this way, the second element connects the first element stably to the frame.

[0015] According to a further preferred aspect of the present invention, the second element in the bicycle component can be configured such that it contacts a part of the frame in a direction that intersects the first direction. The second element thus advantageously exerts the force in the first direction on the frame.

[0016] According to a further preferred aspect of the present invention, the bicycle component can be designed such that at least one of the first element and the second element also have a tool engagement area that can be engaged with a tool. The tool thus enables easy mounting of the bicycle component on the frame.

[0017] According to a further preferred aspect of the present invention, the bicycle component can be designed such that the tool engagement area is defined by at least one inner circumferential region and one outer circumferential region of the first element. This allows the tool to easily engage in the tool engagement area.

[0018] According to a further preferred aspect of the present invention, the bicycle component can be designed such that the first fastening section comprises a first part that is connected to the housing and a second part that pushes the frame away from the housing. The first part and the second part thus exert a force that preferably moves the housing and the frame away from each other.

[0019] According to another preferred aspect of the present invention, the bicycle component comprises the features of claim 9 shown alongside.

[0020] The second threaded section connects to the first and is moved to press the housing against the second part. The internal thread of the second threaded section is connected to the external thread of the first threaded section and moved through it to press the housing against the second part. This advantageously secures the housing to the frame using the first mounting section.

[0021] According to a further preferred aspect of the present invention, the bicycle component can be designed such that the first fastening section comprises an annular element with an inner circumferential section and an outer circumferential section, the first part being defined by the inner circumferential section and the second part by the outer circumferential section. Thus, the first part, defined by the inner circumferential section of the annular element, and the second part, defined by the outer circumferential section of the annular element, exert a force that preferably moves the housing and the frame away from each other.

[0022] According to a further preferred aspect of the present invention, the first fastening section can also have a tool engagement area that can be engaged with a tool. The tool thus enables easy mounting of the bicycle component to the frame.

[0023] According to a further preferred aspect of the present invention, the bicycle component can also comprise a second mounting section that secures the housing to the bicycle frame. The first mounting section and the second mounting section are spaced apart from each other in a predetermined direction. The first mounting section and the second mounting section securely fasten the bicycle component to the frame.

[0024] According to a further preferred aspect of the present invention, the bicycle component can be designed such that the second fastening section has a threaded bore formed in the housing and a coupling element that passes through the frame and is connected to the threaded bore. The second fastening section thus securely fastens the bicycle component to the frame.

[0025] According to a further preferred aspect of the present invention, the housing can accommodate at least part of a motor that assists the propulsion of a bicycle. Thus, the bicycle component that accommodates the motor is stably mounted to the frame.

[0026] According to a further preferred aspect of the present invention, the housing in the bicycle component can be designed such that it can be at least partially housed within the frame. This allows for an improvement in the bicycle's design.

[0027] A mounting structure for a bicycle component according to another aspect of the present invention comprises the first mounting section of the bicycle component according to any one of the first to twenty-first aspects and the frame. The mounting structure of the bicycle component securely fastens the bicycle component to the frame.

[0028] A fastening structure for a bicycle component according to another aspect of the present invention comprises the first fastening section of the bicycle component according to one of the twelfth to seventeenth aspects and the frame. The frame comprises a main frame body and a fastening element separate from the main frame body, and the second part pushes the fastening element away from the housing. In this way, a part that is pressed against the second part by the fastening element is advantageously formed on the frame.

[0029] According to a preferred aspect of the present invention, the fastening structure can be designed such that the fastening element is ring-shaped and comprises an inner circumferential section and an outer circumferential section, the inner circumferential section contacting the first fastening section and the outer circumferential section being attached to the main body of the frame. In this way, the bicycle component is stably attached to the frame.

[0030] According to a further preferred aspect of the present invention, the fastening structure can also include a screw that secures the fastening element to the main frame body. In this way, the fastening element is secured to the main frame body by means of the screw.

[0031] The bicycle component according to the present invention can be stably mounted on the frame.

[0089] The second fastening sections 116 comprise a first through-hole 116A and a second through-hole 116B formed in the housing 112, as well as first coupling elements 140. The second fastening section 116 includes a plurality of projections 113 extending from the outer circumferential section of the first housing 112X around the crankshaft 32A. The projections 113 comprise a first projection 113A and a second projection 113B. The first projection has the first through-hole 116A, and the second projection 113B has the second through-hole 116B. Preferably, there are a plurality of first projections 113A. The first through-hole 116A and the second through-hole 116B extend in the first direction. Preferably, the diameter of the second through-hole 116B is larger than the diameter of the first through-hole 116A. The present embodiment shows two first projections 113A and a second projection 113B.Preferably, the axis of rotation of the crankshaft 32A lies in the axial direction C of the crankshaft 32A in a first region, surrounded by adjacent straight lines connecting the centers of the first through-bores 116A to the center of the second through-bore 116B and a straight line connecting the centers of the first through-bores 116A. Preferably, the crankshaft 32A is located in the first region. There may be three or more first through-bores 116A and two or more second through-bores 116B. One of the first through-bores 116A is preferably positioned such that the crankshaft 32A is located between the engine 48 and the first through-bore 116A in the axial direction of the crankshaft 32A. Preferably, the second through-hole 116B and the other of the first through-holes 116A are provided at locations where the first housing 112X and the third housing 112Z are connected to each other.Preferably, the other of the first through-holes 116A and the second through-hole 116B are provided at the two end sections of the third housing 112Z in the lateral direction around the crankshaft 32A and in the axial direction around the crankshaft 32A. The first through-hole 116A and the second through-hole 116B need not be formed in the first projections 113A and the second projection 113B of the first housing 112X. The first through-hole 116A and the second through-hole 116B may be provided in the outer circumferential section of the first housing 112X. The first housing 112X need not be provided with the two first projections 113A and the second projection 113B and may only be provided with the first projections 113A.In this case, only the first through holes 116A are provided in the housing 112, and a structure connecting a sleeve 150 in the second through hole 116B with a screw is replaced by a structure connecting a screw inserted into the first through hole 116A, which is connected to a threaded section 146A in the second side wall 146.

[0090] The second mounting sections 116 comprise a plurality of mounting surfaces 117. The plurality of mounting surfaces 117 includes a first mounting surface 117A and a second mounting surface 117B. The first through-hole 116A opens in the first mounting surface 117A. The second through-hole 116B opens in the second mounting surface 117B. The first mounting surface 117A is formed on the first projection 113A. The second mounting surface 117B is formed on the second projection 113B. The first mounting surface 117A and the second mounting surface 117B are perpendicular to the axis of rotation of the crankshaft 32A. The first mounting surface 117A is offset from the second mounting surface 117B in the axial direction C of the crankshaft 32A. Preferably, the first mounting surface 117A is located closer to the first mounting section 114 in the axial direction C of the crankshaft 32A than the second mounting surface 117B.The second side wall 146 comprises a first frame mounting part 147A corresponding to the first mounting surface 117A and a second frame mounting part 147B corresponding to the second mounting surface 117B. The first frame mounting part 147A is offset from the second frame mounting part 147B in the axial direction C of the crankshaft 32A. Preferably, the first frame mounting part 147A is located closer to the first mounting section 114 in the axial direction C of the crankshaft 32A than the second frame mounting part 147B. The first through-hole 116A and the second through-hole 116B are preferably arranged such that they do not overlap a line segment connecting the axis of rotation of the crankshaft 32A and the axis of rotation of the rear wheel 30 as viewed from the axial direction C of the crankshaft 32A.Preferably the first through-hole 116A and the second through-hole 116B are offset from the section in which the seat tube 22E is connected to the upper wall 148 and the section in which the chainstay 22G is connected to the upper wall 148.

[0091] As in Fig. As shown in Figure 21, the sleeve 150 is arranged in the second through-hole 116B. Preferably, the sleeve 150 is pressed into the second through-hole 116B of the second projection 113B. The sleeve 150 has an axial end that defines a flange 150B. The outer diameter of the flange 150B is larger than the inner diameter of the second through-hole 116B. The flange 150B is located between the second projection 113B and the main frame body 134. The sleeve 150 is designed such that its position in the second through-hole 116B can be adjusted in the direction of extension of the second through-hole 116B. The inner circumferential section 150A of the sleeve 150 has an internal thread.

[0092] As in Fig. 19 and Fig. As shown in Figure 21, each first coupling element 140 has an external thread 140A. The first coupling elements 140 are inserted through the first through-hole 116A and the second through-hole 116B. The first coupling element 140 inserted into the first through-hole 116A extends through the first through-hole 116A and is connected to the corresponding threaded part 146A in the second side wall 146. The frame 132 has the threaded part 146A into which the first coupling element 140 can be inserted at a position corresponding to the first through-hole 116A. The threaded part 146A has an internal thread. The first coupling elements 140 include screws. The housing 112 is arranged between the screw head of the first coupling member 140, which is inserted through each first through hole 116A, and the second side wall 146 of the frame 132.

[0093] The first coupling element 140, which is inserted through the second through-hole 116B, is connected to the internal thread of the inner circumferential section 150A of the sleeve 150. The second side wall 146 of the frame 132 is positioned between the housing 112 and the screw head of the first coupling element 140 through the second through-hole 116B. A through-hole is formed in the frame 132 at a location corresponding to the second through-hole 116B, into which the first coupling element 140 can be inserted. When assembling the bicycle component 110 on the frame 132, the first coupling elements 140 are inserted into the first through-holes 116A and connected to the corresponding threaded sections 146A in the second side wall 146 to fasten the frame 132 and the housing 112. Then the remaining first coupling element 140 is inserted through the through hole of the frame 132 and connected to the second through hole 116B.If there is a gap between the flange of the sleeve 150 and the frame 132, the connection of the first coupling member 140 moves the sleeve 150 towards the frame 132, so that the flange 150B touches the frame 132.

[0094] As in Fig. 19 and Fig. As shown in Figure 20, the first fastening section 114 is designed to exert a force on the housing 112 and the frame 132, causing the housing 112 and the frame 132 to move away from each other. The first fastening section 114 is designed to exert a force on the housing 112 and the frame 132, causing the housing 112 and the frame 132 to move away in the axial direction C of the crankshaft 32A. More precisely, by connecting the second threaded part 120A to the first threaded part 112A, the first part 120A exerts a force on the housing 112 in the direction A1 towards the second fastening sections 116 due to the axial force of the annular element 124. The second part 122 exerts a force in direction A2, which is opposite to the direction A1, on the frame 132 with the first end face 124C of the ring-shaped element 124.

[0095] As in Fig. 19 and Fig. As shown in Figure 21, the second fastening section 116 is designed to exert a force on the housing 112 and the frame 132, causing them to move towards each other. The second fastening sections 116 are designed to exert a force on the housing 112 and the frame 132, causing them to move towards each other in the axial direction C of the crankshaft 32A. More precisely, the first coupling element 140, which is inserted into the first through-bore 116A, exerts a force on the housing 112 that acts in the direction B1 from the first side wall 144 of the frame 132 onto the surface of the second side wall 146 with the axial force of the first coupling element 140. The first coupling element 140 in the second through-bore 116B acts with the axial force of the first coupling element 140 on the housing 112 in the direction of B2 from the second side wall 146 of the frame 132 to the first side wall 144.Direction B1 and direction B2 are opposite directions.

[0096] A method for mounting the bicycle component 110 on the frame 132 is now described. The method for mounting the bicycle component 110 on the frame 132 comprises a first step, a second step, a third step, and a fourth step.

[0097] In the first step, in a state in which the first fastening section 114 is attached to the housing 112 and the fastening element 136 is supported by the first fastening section 114, a mechanic inserts the bicycle component 110 from below through the first open section 132A of the frame 132 into the receiving space of the component fastening part 142.

[0098] In the second step, the mechanic mounts the housing 112 onto the frame 132 using the second fastening sections 116.

[0099] In the third step, the mechanic fixes the fastening element 136 to the main frame body 134 using the screws 138.

[0100] In the fourth step, the mechanic inserts a tool into the tool engagement area 126 of the first fastening section 114 and rotates the first fastening section 114 in the direction in which the second threaded section 120A of the first fastening section 114 separates from the first threaded section 112A, in order to press the frame 132 against the first end face 124C of the annular element 124 of the first fastening section 114. The third step can be performed before the first step.

[0101] A bicycle component 110 and a fastening structure 160 of the bicycle component 110 according to the fifth embodiment are now described with reference to Fig. 22, Fig. 23 to Fig. 24. The bicycle component 110 according to the fifth embodiment differs from the bicycle component 40 according to the fourth embodiment only in the design of a second fastening section 164 and a fastening structure 160. Otherwise, the bicycle component 110 according to the fifth embodiment corresponds to the bicycle component 110 according to the fourth embodiment. Thus, the same reference numerals are used for the components, which correspond to the respective components of the first embodiment. Such components are not described in detail.

[0102] As in Fig. 22, Fig. 23 to Fig. Figure 24 shows that the bicycle component 110 comprises a housing 112 and the first fastening section 114 for attaching the housing 112 to the bicycle 10. The bicycle component 110 further comprises second fastening sections 164 for attaching the housing 112 to the frame 132 of the bicycle 10.

[0103] The mounting structure 160 of the bicycle component 110 comprises the first mounting section 114 and the frame 132. The mounting structure 160 further comprises the second mounting sections 164. The frame 132 consists of a frame main body 134 and a mounting part 166 separate from the frame main body 134. The mounting structure 160 also includes screws 168 for attaching the mounting part 166 to the frame main body 134. The mounting structure 160 also includes nuts 170 which are connected to the screws 168. Fig. The seat tube 22E and the chainstay 22G are not shown.

[0104] The fastening element 166 is ring-shaped. The fastening element 166 comprises an inner circumferential section 166A and an outer circumferential section 166B. The inner circumferential section 166A is ring-shaped. The inner circumferential section 166A of the fastening element 166 is similar in shape to the inner circumferential section of the fastening element 136. The outer circumferential section 166B projects radially outwards from the inner circumferential section 166A. There are multiple outer circumferential sections 166B. The outer circumferential sections 166B are not continuous in the circumferential direction. However, the outer circumferential sections 166B can be continuous in the circumferential direction. Each outer circumferential section 166B has a through-hole 166C. The outer circumferential sections 166B of the fastening element 166 are connected to the frame base body 134.

[0105] The second fastening sections 164 comprise a first through-hole 116A and a second through-hole 116B extending through the housing 112, the screws 168, and the nuts 170. The sleeve 150 is positioned in the second through-hole 116B. The screws 168 are inserted into the first through-hole 116A and the second through-hole 116B. The inner circumferential section 150A of the sleeve 150 includes an internal thread connected to the screw 168.

[0106] The second fastening sections 164 serve to fasten the housing 112 to the frame 132 with the screws 168 and the nuts 170 and to fasten the fastening part 166 to the main frame body 134.

[0107] A first frame through-hole 134A and a second frame through-hole 134B extend through the main frame body 134 in the axial direction C of the crankshaft 32A. As in Fig. As shown in Figure 23, in a state where the bicycle component 110 is attached to the frame main body 134, the first through-hole 116A is aligned with the first frame through-hole 134A. The first frame through-hole 134A is formed in a portion of the frame main body 134, with the upper wall 148 connecting the first side wall 144 and the second side wall 146. The first frame through-hole 134A extends through the first side wall 144, the upper wall 148, and the second side wall 146 in the first direction. The screw 168 inserted into the first through-hole 116A extends through the first through-hole 116A, the first frame through-hole 134A, and the through-hole 166C of the fastening part 166 from the side of the second side wall 146. The nut 170 is connected to the external thread at the distal end of the screw 168 from the side of the fastening part 166 opposite the main frame body 134.The screw 168 in the first through-hole 116A can extend through the through-hole 166C of the fastener 166, the first frame through-hole 134A, and the first through-hole 116A of the fastener 166, and the nut 170 can be connected to the external thread of the distal end 168A of the screw 168 from the side of the second housing 112Y. The screw 168, located in the first through-hole 116A, and the nut 170 connect the housing 112, the frame main body 134, and the fastener 166 between the screw head and the nut 170.

[0108] As in Fig. As shown in Figure 24, in a state where the bicycle component 110 is attached to the frame main body 134, the second through-hole 116B is aligned with the second frame through-hole 134B. The second frame through-hole 134B has a first section 134C and a second section 134D. The first section 134C is defined where the upper wall 148 does not connect the first side wall 144 and the second side wall 146. Furthermore, the first section 134C extends through the first side wall 144 in the first direction. The second section 134D extends through the second side wall 146 in the first direction. The screw 168 inserted into the second through hole 116B extends from the second side wall 146 through the second section 134D of the second frame through hole 134B, the second through hole 116B, the first section 134C of the second frame through hole 134B and the corresponding through hole 166C of the fastening part 166.The nut 170 is coupled to the external thread at the distal end of the screw 168 from the side of the fastening part 166 opposite the frame main body 134. The screw 168, which is inserted through the second through-hole 116B, and the nut 170 enclose the second side wall 146 of the frame main body 134 between the screw head and the flange 150B of the sleeve 150. The screw 168 and the nut 170 also enclose the fastening part 166 between the nut 170 and the first side wall 144 of the frame main body 134.

[0109] The second fastening sections 164 are designed to exert a force on the housing 112 and the frame 132, causing them to move towards each other. Specifically, the second fastening sections 164 exert a force on the housing 112 and the frame 132, causing them to move closer together in the axial direction C of the crankshaft 32A. More precisely, the screw 168 inserted into the first through-hole 116A exerts a force on the housing 112, acting in the direction B1 from the first side wall 144 of the frame 132 to the surface of the second side wall 146, with the axial force of the screw 168.

[0110] A method for attaching the bicycle component 110 to the frame 132 is now described. The method for attaching the bicycle component 110 to the frame 132 comprises a first step, a second step, a third step, and a fourth step.

[0111] In the first step, in a state in which the first fastening section 114 is attached to the housing 112 and the fastening element 136 is supported by the first fastening section 114, the mechanic inserts the bicycle component 110 from below through the first open section 132A of the frame 132 into the receiving space of the component fastening part 142.

[0112] In the second step, the mechanic inserts each screw 168 through the first through-hole 116A of the housing 112, the first frame through-hole 134A, and the through-hole 166C of the mounting part 166. The mechanic then connects the nut 170 to the screw 168 to fasten the housing 112 and the mounting part 166 to the main frame body 134. The mechanic then inserts the screw 168 into the second frame through-hole 134B, the second through-hole 116B, and the through-hole 166C of the mounting part 166 until the flange 150B of the sleeve 150 contacts the second side wall 146. Finally, the mechanic connects the nut 170 to the screw 168 to secure the mounting part 166 and the main frame body 134.

[0113] In the third step, the mechanic inserts a tool into the tool engagement area 126 of the first fastening section 114 and rotates the first fastening section 114 in the direction in which the second threaded section 120A of the first fastening section 114 separates from the first threaded section 112A in order to press onto the fastening part 166 with the first end face 124C of the annular element 124 of the first fastening section 114.

[0114] The description relating to the embodiment above illustrates, without any limiting intent, an applicable form of a bicycle component according to the present invention. In addition to the embodiments described above, the bicycle component according to the present invention applies, for example, to the modified examples of the embodiments described above and combinations of at least two of the modified examples that do not contradict each other, as described below. In the modified examples described below, the same reference numerals are used for the components, corresponding to the components of the embodiment above. Such components are not described in detail.

[0115] The second assembly section 46 of the first and second embodiments can be converted into a second fastening section 104 according to Fig. 25. The second fastening section 104 has a plurality of threaded holes 106 and a plurality of first coupling links 108. The threaded holes 106 are formed in the housing 42. The first coupling links 108 are screws. The first coupling links 108 extend through the frame 22 and are connected to the threaded holes 106. The first coupling links 108 have external threads that connect to internal threads of the threaded holes 106. The threaded holes 106 and the first coupling links 108 are arranged at intervals around the crankshaft 32A.

[0116] As in Fig. 26 and Fig. As shown in Figure 27, the frame 22 can include a first open section 23G instead of the first open section 23A, which opens towards the underside of the bicycle 10. The first open section 23G is located above the lower part of the mounting part 22D and the part of the down tube 22C connected to the mounting part 22D. The bicycle component 40 is inserted into the opening of the first open section 23G from below and attached to the frame 22. The opening of the first open section 23G extends rearward into the side walls 23D and 23E of the mounting part 22D, from where the crankshaft 32A is provided. Preferably, a cover (not shown) is attached to the first open section 23G.

[0117] As in Fig. 28, can be seen in the modified example of Fig. 26 and Fig. 27 the first coupling element 74 is replaced by the first coupling element 108. In the modified example in Fig. 16 The first fastening section 44 can be modified so that it has the same structure as the second fastening section 46.

[0121] In the first embodiment, the second embodiment and their modified examples, the first coupling elements 74, 95 and 108 can each have the form of a non-continuous ring. For example, the first coupling elements 74, 95 and 108 can each be C-shaped.

[0122] In the first to third embodiments and their modified examples, at least one of the first elements 68 and 102 and the second element 70 can have the form of a non-continuous ring. For example, the first elements 68 and 102 and the second element 70 can be C-shaped.

[0123] In the first to third embodiments and their modified examples, the projections 70F of the second element 70 can be omitted. In this case, the recesses 22X of the frame 22 can be omitted.

[0124] In the housings 42, 94, and 112 of the bicycle components 40, 92, and 110, a gearbox can be provided instead of or in addition to the motor 48. In this case, the housings 42, 94, and 112 can accommodate at least part of the gearbox. The gearbox changes the rotational speed of the input shaft to the crankshaft 32A and outputs the rotational speed to the front rotating body 36.

[0125] In each of the embodiments and modified examples, the positions of the first mounting sections 44, 96 and 114 and the second mounting sections 46, 98, 104, 116 and 164 can be changed. For example, the first mounting sections 44, 96 and 114 can be arranged on the right side of the housings 42, 94 and 112 and the second mounting sections 46, 98, 104, 116 and 164 on the left side of the housing 42.

[0126] In each of the embodiments and the modified examples, a structure similar to that of the first fastening sections 44, 96 and 114 can be provided on the side of the second side surfaces 42Y and 94Y. In this case, the second fastening sections 46, 98, 104, 116 and 164 can be omitted.

[0128] In the fifth embodiment and the modified examples, the housing 112 can contain only the first through-hole 116A and not the second through-hole 116B as in the fourth embodiment.

[0129] In the fourth and fifth embodiments and their modified examples, the first through-hole 116A and the second through-hole 116B can be formed in the second housing 112Y.
