     DETAILED DESCRIPTION OF THE INVENTION 
     The following illustrative embodiments and drawings are provided to illustrate the present disclosure, these and other advantages and effects can be clearly understood by persons skilled in the art after reading the disclosure of this specification. As shown in  FIG. 1 , an integrated handlebar  100  of a bicycle according to a first embodiment of the present disclosure includes a handlebar  10  and two integrated control devices  30 . 
     The handlebar  10  includes a stem  12  on a middle section thereof. The stem  12  is adapted to be installed on a head tube  1  of a bicycle. The handlebar  10  has two free ends  14 , which are disposed at two sides of the stem  12  respectively, and adapted to be held by a bicycle rider to control a riding direction. 
     In the current embodiment, the two integrated control devices  30  are respectively installed on the two free ends of the handlebar  10 . Since the two integrated control devices  30  have the same design and are arranged symmetrically, one of the integrated control devices  30  would be explained as an example in the following description. 
     As shown in  FIG. 2  to  FIG. 4 , the integrated control device  30  includes a base  32 , a brake lever  34  and an electronic controller  36 . 
     The base  32  is adapted to be installed on the free end  14  of the handlebar  10 . In the current embodiment, the handlebar  10  has a hollow structure, which includes a fixing portion  33 , wherein one end of the fixing portion  33  is inserted into the free end  14  of the handlebar  10  and engaged with the handlebar  10 . However, it is not limited thereto. In other embodiments, the base  32  could be engaged with the free end  14  of the handlebar  10  with other methods. 
     The brake lever  34  has a front end  34   a  and a rear end  34   b  which are opposite to each other. Wherein, the front end  34   a  of the brake lever  34  is connected to the base  32  via a pivot, thereby the brake lever  34  can be pivotally controlled corresponding to the base  32 . The brake lever  34  is adapted to actuate a brake of the bicycle (not shown), whereby the rider could control the brake lever  34  with his fingers to stop or decelerate the bicycle. 
     Besides, the brake lever  34  includes a mounting portion  35 , which is located at a distance not greater than ¾ length of the brake lever  34  from the rear end  34   b , i.e., it is shown as a range of ¾L in  FIG. 2 , and is not directly located on the rear end  34   b . Further, in the current embodiment, the mounting portion  35  is a recess  351  disposed at a distance of ½ length of the brake lever  34  from the rear end  34   b , i.e., it is shown as a range of ½L in  FIG. 3 . 
     More detail, referring to  FIG. 3 , the electronic controller  36  of this embodiment is designed based on a rocker switch. The electronic controller  36  includes a base portion  361 , a bottom plate  362 , a sealing pad  363 , a circuit board  364  and an operation member  37 . The base portion  361  is disposed in the brake lever  34  toward the mounting portion  35 . Wherein, each end of the base portion  361  has a protrusion  36   a , each of which is engaged with a spring  36   b , a button  36   c  and an o-ring  36   d . The bottom plate  362  is pivotally connected with the base portion  361  via a pivot  36   e , thereby being able to pivot corresponding to the base portion  361 . The bottom plate  362  has two through holes  36   f , each of which is disposed corresponding to each of the two protrusions  36   a . The sealing pad  363  is disposed on one side of the bottom plate  362  which is opposite to the base portion  361 , whereby the bottom plate  362  is disposed between the sealing pad  363  and the base portion  361 , wherein the sealing pad  363  has two projections  36   g  which are fitted in the through holes  36   f  relatively. The circuit board  364  is disposed on the operation member  37  and has two contact portions  36   h  corresponding to the through holes  36   f , whereby an electronic signal is sent by the circuit board  364  according to a trigger on each of the contact portions  36   h.    
     The operation member  37  is integrally formed and fixed to the bottom plate  362  so as to make the circuit board  364  be installed between the operation member  37  and the bottom plate. In addition, the operation member  37  has a first operation part  37   a  and a second operation part  37   b , wherein after the electronic controller  36  is installed on the brake lever  34 , a shape of the operation member  37  is matched with the mounting portion  35 , whereby the first operation part  37   a  is located on the mounting portion  35  and at about a distance of ½ length of the brake lever  34  from the rear end  34   b , while the second operation part  37   b  is located on the mounting portion  35  adjacent to the rear end  34   b  of the brake lever  34 . 
     Whereby, with the aforementioned design, the rider could control the first operation part  37   a  and the second operation part  37   b  with his fingers. As illustrated in  FIG. 5 , when the rider holds the handlebar  10  with his hand  2  and triggers the first operation part  37   a  or the second operation part  37   b  with his fingers to control the operation member  37 , the bottom plate  362  would be driven by the operation member  37  and moving pivotally corresponding to the base portion  361 , and thereby the relative button  36   c  on the protrusion  36   a  of the base portion  361  would pass through the O-ring  36   d  and the through hole  36   f  then abuts against the sealing pad  363 , so as to make the corresponding contact portion  36   h  of the circuit board  364  be triggered by the protrusion portion  36   g  of the sealing pad  363 . Therefore, the contact portion  36   h  of the circuit board  364  sends out an electronic signal to a corresponding electronic component on the bicycle. The aforementioned electronic device includes electronic components, such as an electronic derailleur system, an electronic seat post, a power motor or an electronic suspension system, but it is not limited thereto. 
     In other words, when the first operation part  37   a  is controlled by the rider to trigger the circuit board  364  of the electronic controller  36 , the circuit board  364  would output an electronic signal for controlling the electronic component to execute a first action. On the other hand, when the second operation part  37   b  is controlled by the rider to trigger the circuit board  364 , the circuit board  364  would output an electronic signal for controlling the electronic component to execute a second action, which is different from the first action. More detail, when the electronic component is an electronic derailleur system as an example, the first action and the second action could be an upshifting or a downshifting movement for the electronic derailleur system, respectively. However, when other types of electronic components are adopted, the first action and the second action are not limited to the examples mentioned above. 
     In this way, by utilizing the design of the integrated handlebar  100  and the integrated control device  30  of the present disclosure, the rider could touch or trigger the electronic controller  36  disposed on the brake lever  34  with his fingers when holding the handlebar  10  or a portion of the handlebar  10  close to the free end. The integrated control device  30  in the present disclosure is not only ergonomically designed, but also can be smoothly controlled by the rider, by which, the rider could respond to the traffic condition quickly. Moreover, the integrated control device  30  is suitable for the rider to use his middle finger and ring finger to control the electronic controller  36  specially. 
     Furthermore, the first operation part  37   a  and the second operation part  37   b  of the operation member  37  face toward a lateral side direction of the bicycle, whereby the rider could control the first operation part  37   a  or the second operation part  37   b  with his fingers conveniently when holding on a terminal end of the handlebar  10  with his hands. Referring to  FIG. 2 , from a side view of the handlebar  10 , the brake lever  34  has an exterior edge  340  which is disposed away from the handlebar  10 . In general, when the rider controls the brake lever  34 , by pulling the exterior edge  340  of the brake lever  34  with his fingers and drives the brake lever  34  to rotate pivotally corresponding to the base  32  to brake. Hence, the operation member  37  of the electronic controller  36  is preferably disposed between the exterior edge  340  and the fixing portion  33 , or between the exterior edge  340  and the handlebar  10 , and is spaced apart from the exterior edge  340  with a gap. Whereby, the possibility of mis-triggering the electronic controller  36  by the rider is lower, which then improves the accuracy of controlling. 
     As shown in  FIG. 6  and  FIG. 7 , an integrated control device  30 ′ of a second embodiment according to the present disclosure includes a structure similar to that of the integrated control device  30  mentioned above. The description of the identical portions of the structure is omitted here. The integrated control device  30 ′ is different from the first embodiment in the mounting portion  35 ′ of the brake lever  34 ′, the mounting portion  35 ′ further includes two recesses  352 ,  353  which are disposed at two opposite sides thereof. Wherein, the first recess  352  is identical with that of the first embodiment and is disposed at a distance of ½ length of the brake lever  34 ′ from the rear end, i.e., it is shown as a range of ½L in  FIG. 7 , while the second recess  353  on the opposite side is disposed at a distance of ⅔ length of the brake lever  34 ′ from the rear end, i.e., it is shown as a range of ⅔L in  FIG. 7 . The operation member  37 ′ of the integrated control device  30 ′ further includes a third operation part  37   e  apart from the first operation part  37   c  and the second operation part  37   d , wherein the third operation part  37   e  is connected to the first operation part  37   c  via a bar  37   f , more specifically, the bar  37   f  connected with both of the inner surfaces of the third operation part  37   e  and the first operation part  37   c . Furthermore, the first operation part  37   c  and the second operation part  37   d  are both positioned in the first recess  352 , while the third operation part  37   e  is installed in the second recess  353 . 
     In this way, when the rider triggers the third operation part  37   e  with one of his fingers, the third operation part  37   e  would drive the first operation part  37   c  and the second operation part  37   d  to move simultaneously. Thereby the circuit board  364  is being triggered to generate an electric signal correspondingly. In the current embodiment, since the bar  37   f  is connected to both of the inner surfaces of the first operation part  37   c  and the third operation part  37   e , when the third operation part  37   e  is being triggered, the operation member  37 ′ could be levered to trigger the contact portion  36   h  of the circuit board  364  corresponding to the second operation part  37   d , so as to generate an electronic signal. 
     It shall be noted that the operation member not only could be integrally formed, such as the operation members  37 ,  37 ′ mentioned above, the operation member of the present disclosure also could be constituted by a plurality of independent components in other embodiments, whereby the first operation part, the second operation part, and the third operation part could be disposed on different components respectively. Moreover, the electronic controller could be further designed and utilized with a basic structure of a rocker switch circuit, a push button switch or other types of switch circuits, and is not limited to the configuration and the amount of the components as mentioned above. 
     Whereby, the third operation part is not connected and not operated together with the first operation part or the second operation part. When the third operation part is triggered by the rider, the electronic controller would output an electronic signal for actuating a third action to control the electronic component, wherein the third action could be identical with or different from the first action or the second action so as to perform flexible operation. For instance, when the electronic component is an electronically adjustable seat tube as an example, the first action generated by triggering the first operation part could be lifting the seat tube, the second action generated by triggering the second operation part could be lowering the seat tube, and the third action generated by triggering the third operation part could be locking the height of the seat tube. The above examples are exemplified only, in practice, the operation and the corresponding action may be varied depending on its requirement and are not limited thereto. 
     Furthermore, as illustrated in  FIG. 8 , an integrated handlebar of a third embodiment according to the present disclosure includes a handlebar, two integrated control devices  30 ″ and two auxiliary controllers  50 . Wherein, the handlebar includes a main handlebar  15  and two auxiliary handlebars  20 . The main handlebar  15  and the integrated control device  30 ″ are identical with those of the first embodiment, and therefore the related descriptions are omitted here. The integrated handlebar  200  of the third embodiment is different from those of the aforementioned embodiments in that the integrated handlebar  200  further includes two auxiliary handlebars  20  and two auxiliary controllers  50 . 
     To facilitate bicycle riding, the two auxiliary handlebars  20  are disposed on a middle section of the main handlebar  15  and arranged at two lateral sides of the stem respectively. The two auxiliary handlebars  20  extend forwardly with respect to the bicycle, which enables the rider to hold and control a riding direction of the bicycle. The integrated handlebar  100  further includes a bridge  40  adapted to be installed with the two auxiliary handlebars  20 . Additionally, on each side of the bridge  40  is disposed with a pad  42 , whereby the rider could lean over to rest his arms or elbows on the two pads  42  to have his upper body weight being received thereon and reduce the weight loading on his waist in a long-time riding. Meanwhile, it also enables the rider to lower the height of his upper body, which could reduce the wind resistance in the riding journey, and thereby to save his energy and increase the riding speed. 
     As illustrated in  FIG. 8  and  FIG. 9A to 9C , the two auxiliary controllers  50  are respectively installed on the free ends of the two auxiliary handlebars  20 . Each of the two auxiliary controllers  50  includes an engaging portion  52 , two operation elements  54   a ,  54   b  and an electronic controller (not shown). The engaging portion  52  and the two operation elements  54   a ,  54   b  are respectively arranged on two opposite ends of the auxiliary controller  50 , wherein the engaging portion  52  is adapted to be engaged with the free end of the auxiliary handlebar  20  to install the auxiliary controller  50  on the auxiliary handlebar  20 , and the two operation elements  54   a ,  54   b  are located on a front end of the auxiliary controller  50  which faces forwardly with respect to the bicycle. 
     When the two operation elements  54   a ,  54   b  are triggered by the rider, the electronic controller would be triggered to output an electronic signal to control an electronic component of the bicycle. In the current embodiment, the two operation elements  54   a ,  54   b  are respectively arranged on two opposite sides of the front end, wherein the operation element  54   a  faces toward a top side of the bicycle, while the operation element  54   b  faces toward a downside of the bicycle. In this way, when the rider holds the auxiliary handlebar  20 , it is convenient for the rider to trigger the operation element  54   a  with one of his fingers (e.g. thumb) to trigger an electronic signal for actuating a first action or a second action, or to trigger the operation element  54   b  with another one of his fingers (e.g. forefinger or middle finger) to trigger an electronic signal for actuating a second action or a first action. In an alternative embodiment, the installation direction of the auxiliary controller  50  could be adjusted according to the rider&#39;s habit to make the operation elements  54   a ,  54   b  face toward other directions. Meanwhile, the number of the operation elements could be one, three, or more than three, and is not limited to the above embodiments. 
     In addition, the two integrated control devices  30 ″ are not limited to be installed on the two main handlebars  15 . For instance, in one embodiment, the two integrated control devices  30 ″ could be installed on the free ends of the two auxiliary handlebars  20 , whereby the rider could control the two integrated control devices  30 ″ conveniently when riding the bicycle with resting his arms or elbows on the two pads  42  and holding the two auxiliary handlebars  20  with his hands, so as to control the brake and the electronic control device of the bicycle. Besides, the above description is not only related to the integrated control device  30 ″ of this embodiment, but is also applicable to the integrated control devices  30 ,  30 ′ of the first embodiment and the second embodiment. 
     Furthermore, as illustrated in  FIG. 10 , an integrated handlebar  300  of a fourth embodiment according to the present disclosure is designed based on the configuration of the integrated handlebar  200  of the aforementioned embodiments, wherein it is particular that the integrated handlebar  300  includes four integrated control devices  30 ″ and is without the auxiliary controller  50  of the aforementioned embodiment. Wherein, two of the four integrated control devices  30 ″ are installed on the main handlebar  15  respectively, each of which is engaged with one of the two free ends of the main handlebar  15  with a base thereof, while the other two integrated control devices  30 ″ are installed on the two auxiliary handlebars  20  respectively, each of which is engaged with one of the two free ends of the auxiliary handlebars  20  with a base thereof. By way of the above design, when the rider changes his riding posture, such as changing from holding on the main handlebar  15  to the auxiliary handlebars  20 , or changing from holding on the auxiliary handlebars  20  to the main handlebar  15 , the rider still can control the brake and the derailleur flexibly and conveniently, which is not only ergonomically designed, but also can be smoothly controlled by the rider. 
     In other applications, the integrated control device could be installed on a single handlebar, and it not necessary to be installed with at least two integrated control devices. Meanwhile, the locations of each of the operation members are not limited to the embodiments exemplified above, as long as each of the operation members is located at a distance not greater than ¾ length of the brake lever from the rear end, it would match the ergonomics design and provide better control feeling. It must be pointed out that the embodiments described above are only some embodiments of the present disclosure. All equivalent structures which employ the concepts disclosed in this specification and the appended claims should fall within the scope of the present disclosure.
