摘要： A spoke includes an axle body and two connecting elements. The axle body has a middle segment and two connecting segments. The two connecting segments are respectively connected to two opposite sides of the middle segment. The two connecting segments each have a first peripheral surface, and the two first peripheral surfaces each are formed with a friction enhancing structure. The two connecting elements respectively wrap at least a part of the two friction enhancing structures by means of injection molding. The two connecting elements each have a second peripheral surface facing away from the axle body, and the two second peripheral surfaces each are formed with a connecting structure.

摘要： An automatic control system includes a host connected to the actuator and the inputting device of a bicycle. The actuator controls the motor to drive the mechanical structure to generate a displacement. The inputting device receives the external information by manually entering or automatically sensing via the inputting device to obtain an inputting parameter. In each riding journey of the predetermined path, the host records the inputting parameter that the controller of the actuator drives the motor based on and the time spent for the riding journey to form a riding information. When the rider rides the bicycle on the predetermined path again, the host selects one of the riding information, which has the shortest time spent for the riding journey, as an operating parameter for controlling the actuator, so that the host automatically controls the actuator based on the operating parameter to prevent the cyclist from distracting.

摘要： A transmission system of a decelerating mechanism includes a planetary gear unit including a sun gear being adjacent to the first surface and a planetary gear set and a holder including a carrier and several planetary shaft units rotatably disposed on the carrier. The carrier has a first surface and a second surface that face opposite directions. The planetary gear set has several first gears being adjacent to the first surface, respectively fitting around the planetary shaft units, and meshing with the sun gear, several second gears being adjacent to the second surface and being coaxially disposed with the first gears, and an internal gear ring meshing with the second gears. By respectively arranging the first gears and the second gears on two opposite sides of the carrier, mutual interference therebetween while turning could be avoided, and an overall volume of the transmission system could be reduced.

摘要： A bicycle power meter includes a strain gauge, a signal processing unit, a processor, and a signal transmitter. The strain gauge is disposed on at least one of an outer peripheral wall and an inner peripheral wall of a stem of a bicycle. The signal processing unit connected to the strain gauge by signal correspondingly outputs an electrical signal based on a deformation of the stem detected by the strain gauge. The processor connected to the signal processing unit by signal receives the electrical signal sent by the signal processing unit and calculates a measuring value based on the electrical signal and sends the measuring value in an output signal. The signal transmitter connected to the processor by signal receives the output signal sent by the processor and converts the output signal to a wired or wireless signal and sends the wired or wireless signal to a terminal device.

摘要： A rear derailleur of a bicycle includes a fixing portion connected to a frame of the bicycle, a linkage assembly pivotally connected between the fixing portion and the moving portion, a moving portion pivotally connected to the linkage assembly, a chain guide assembly connected to the moving portion, and a driving assembly including a clutch assembly, a motor, and a driving gear assembly connected to the clutch assembly. The clutch assembly is disposed between the fixing portion and the linkage assembly and includes a first clutch member and a second clutch member. When a relative rotational torque between the first clutch member and the second clutch member is greater than a predetermined resistance, the first clutch teeth and the second clutch teeth shift relatively. Thereby, the driving gear assembly or the output shaft of the motor could be prevented from damaging.

摘要： A rim includes a rim body and a spoiler portion. The rim body is annular and has two opposite side surfaces connected by an intermediate portion. Each surface has a radial inner portion located on a radial inner side and a radial outer portion located on a radial outer side. The radial outer portion has an extension portion and a radial outer periphery at the outermost side. The extension portion is extended toward the radial outer side from a connecting portion between the radial outer portion and the intermediate portion. The spoiler portion has a plurality of spoiler profiles concavely formed on the radial outer portion of at least one of the two side surfaces. At least one of the spoiler profiles is partially disposed on the extension portion without forming any undulation on the radial outer periphery.

摘要： A control device for a bicycle is disposed on a handlebar and includes a body, an electronic module, at least one switch, and at least one input member. The body includes a plugged portion and a holding portion. The plugged portion is disposed inside the handlebar via an opening of the handlebar. The holding portion is connected to the plugged portion and is disposed outside the opening. The electronic module is disposed in the plugged portion and has at least one surface. The switch is disposed on the surface of the electronic module to selectively control the electronic module to send an electronic signal. The input member is disposed on the holding portion and extends into the plugged portion and moves in an operating direction to actuate the switch. The operating direction is not perpendicular to the surface and a longitudinal axis direction of the plugged portion.

摘要： A bicycle sprocket comprises a sprocket body, a sprocket ring, a plurality of limiting members, and a plurality of reinforcing members. The sprocket ring has a plurality of ring pieces, each of which includes a plurality of sprocket teeth. Through the movement of the sprocket ring relative to the sprocket body, the axially movable scope of the sprocket ring limited by the limiting members, and the binding strength between the adjacent ring pieces stabilized by the reinforcing members, the sprocket ring can shift relative to the sprocket body in order to reduce the friction and noise generated by the sprocket teeth of the ring pieces and the chain when the bicycle sprocket drives the chain to move.

摘要： An electronic power control assembly for a bicycle electronic device, a system having the same, and a control method thereof are disclosed. The electronic power control assembly is adapted to be electrically connected to a power source and a control module for controlling at least one electronic device on a bicycle to operate and includes a sensing unit for sensing a motion state of the bicycle, a first timing unit adapted to count a first predetermined time period, and a first control unit. When the sensing unit senses that the bicycle is in a moving state, the first control unit controls the first timing unit to recount and controls the power source to supply electricity to the control module. When the first timing unit finishes counting the first predetermined time period, the first control unit controls the power source to stop supplying electricity to the control module.
