Abstract: A headset of a bicycle includes a bearing base, a bearing cup, at least two sealing elements, damping fluid, and a bearing. The bearing base is adapted to be sleeved on a fork tube. The bearing cup is adapted to be abutted against an end, close to the fork tube, of a head tube, and a gap is formed between the bearing cup and the bearing base. The at least two sealing elements are disposed between the bearing cup and the bearing base, and the at least two sealing elements, the bearing cup and the bearing base seal the gap to form a damping section. The damping fluid is disposed in the damping section to provide damping force. The bearing is disposed between the bearing base and the bearing cup and is abutted against the bearing base and the bearing cup.

Abstract: A bearing seat suitable for receiving a bearing includes an annular body, a first outer-radial flange and a second outer-radial flange. The annular body includes a peripheral wall. The peripheral wall has a first end, a second end, an inner matching surface and an outer surface. A thickness difference between the maximum thickness and the minimum thickness of the peripheral wall is within 30%. A portion of the inner matching surface is suitable for contacting and matching with an outer matching surface of the bearing. The first outer-radial flange protrudes from the outer surface adjacent to the first end and extends to the first end. The second outer-radial flange protrudes from the outer surface adjacent to the second end and extends to the second end. The overall structure of the bearing seat is uniform, which can reduce warpage and deformation caused by uneven shrinkage during the injection process.

Abstract: A bicycle headset includes a first casing and a second casing for being engaged with a head tube and a fork of a bicycle, respectively. The first casing has an axial direction. A bearing abuts between the first casing and the second casing. A first restricting member, having a first restricting surface, is connected to the second casing to rotate along with the second casing. A second restricting member, having a second restricting surface, is connected to the first casing. The restricting members move away from or toward each other in the axial direction. An elastic member abuts between the first casing and the second restricting member or between the second casing and the first restricting member and provides a force in the axial direction for urging one of the restricting members to move toward the other to allow the two restricting surfaces abut against each other, thereby forcing the fork to steer back.

Abstract: A bearing includes a first ball track and a second ball track being annular and respectively disposed on an inside and an outside of the bearing. The first ball track has a first side wall and a second side wall. A first track and a first damping element are disposed on the first side wall. The second ball track has a third side wall and a fourth side wall. A second track and a second damping element are disposed on the third side wall. The first track and the second track jointly form a receiving space for disposing a plurality of balls abutted by both the first track and the second track. The second damping element and the first damping element get in contact and rub against each other to be rotatable relative to each other. The present disclosure provides a damping for rotating through rubbing between the damping elements.

Abstract: 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.

Abstract: A bicycle headset includes a fixed member, wherein the headset is fixed onto a headtube of a bicycle via the fixed member. A steerer tube of a fork passes through the headtube and is connected to a fork portion. The fixed member has a first contour including a first guiding section, a second section, and a joint section that connects the first section and the second section and is located at the highest site among the first contour. A rotating member is fixed onto the steerer tube. A movable member is disposed onto the rotating member and is movable along an axial direction of the steerer tube. An elastic member urges the movable member to allow a second contour of the movable member to constantly touch the first contour of the fixed member, thereby preventing a stem connected to the steerer tube from overly turned and assisting to steer back.

Abstract: 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 handlebar 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 handlebar 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.
