Abstract: A speed-changing method of bicycle suitable for controlling a gear ratio of a bicycle is provided. The bicycle has a front electronic derailleur, a rear electronic derailleur, a controller, and a controlling switch. The controller stores a gear-ratio table. The speed-changing method of bicycle includes the following steps. The controlling switch is triggered to generate a speed-increasing signal or a laborsaving signal. The controller controls the front and rear electronic derailleurs according to the speed-increasing signal or the laborsaving signal to increase the gear ratio along a speed-increasing path of the gear-ratio table or decrease the gear ratio along a laborsaving path of the gear-ratio table respectively. On the other hand, the front and rear electronic derailleurs are started simultaneously at a first switch point of the speed-increasing path or a second switch point of the laborsaving path, and the first switch point is different from the second switch point.

Abstract: An automatic control method suitable for a bicycle system is provided. The bicycle system has a gear ratio and a toque ratio formed by an auxiliary torque and a pedaling torque. The automatic control method includes following steps: sensing a pedaling cadence and the pedaling torque of the bicycle system in a riding state; setting a first cadence threshold and a second cadence threshold according to a preset pedaling cadence while the first cadence threshold is greater than the second cadence threshold; and determining whether the pedaling cadence is greater than the first cadence threshold or less than the second cadence threshold so as to set to increase or decrease the gear ratio. In addition, a bicycle system suitable for the automatic control method is also provided.

Abstract: An automatic control shock absorber system for a bicycle is provided. The system includes one or more sensors. A controller outputs a control signal to a damping adjuster according to the one or more sensors, such that the damping adjuster controls level of damping force based on the sensors.

Abstract: An apparatus for automatically controlling a shock absorber system for a bicycle comprises a position sensor system configured to detect information indicative of a position of a rider of the bicycle and a controller in communication with the position sensor system. The controller adjusts the shock absorber system based on the detected information. The adjusting of the shock absorber system can include adjusting a damping force of the shock absorber system and/or adjusting sag of the shock absorber system.

Abstract: An apparatus for detecting a riding posture is suitable for detecting a riding posture of a rider riding a bicycle. The apparatus for detecting a riding posture includes a sensor and a controller. The sensor is connected to the bicycle to sense a relationship between the rider and the bicycle and output a sensing signal accordingly. The controller receives the sensing signal and determines whether the riding posture of the rider is a sitting posture or a standing posture according to the sensing signal.

Abstract: A system adapted for use with an exercise machine for monitoring exercise performance includes: a pulse detecting unit adapted for detecting a pulse of a user; a torque detecting unit adapted to detect a torque exerted by the user; a user interface unit for allowing user input of user-specific parameters and displaying data to the user; and a control unit electrically coupled to the other elements. The control unit determines a target exercise amount for the user with reference to the pulse, the torque, and the user-specific parameters. The control unit further determines an actual exercise amount during exercise by the user with reference to the torque. The user interface unit displays the target exercise amount through an exercise indicating pattern that is selectively activated according to the actual exercise amount.

Abstract: A bicycle pedal is adapted to be rotatably mounted on a pedal shaft of a bicycle about an axis, and includes a tread having upper and lower treading surfaces disposed respectively at two opposite sides of the axis. The upper and lower treading surfaces converge along the axis such that a first thickness defined between first surface ends of the upper and lower treading surfaces is larger than a second thickness defined between second surface ends of the upper and lower treading surfaces, thereby enabling the rider to rest the inside and outside portions of a foot on one of the upper and lower treading surfaces for stead and smooth pedaling of the bicycle.

Abstract: A foldable bicycle includes front and rear frames pivotally connected to each other by a horizontal journal pin that is non-parallel to a rear wheel axle such that the rear frame is turnable between unfolded and folded positions. A bracing lever has a pivot end pivotally mounted on one of the front and rear frames, and a retaining end operable to turn between a retained position to be prevented from disengaging from the other one of the front and rear frames when the rear frame is in the unfolded position, and a releasing position to permit turning of the rear frame so as to fold the bicycle.

Abstract: A vehicle chassis includes: first and second chassis parts; a locking unit including a first engaging part that is pivoted to the first chassis part and that is formed with first and second engaging recesses, a second engaging part mounted on the second chassis part and formed with a tongue such that the tongue pushes the first engaging part to rotate from an unlocking position to a locking position and slides into the first recess during coupling of the first and second chassis parts; and a retaining unit including a retaining part that is pivoted to the first chassis part and that has an engaging end which extends into the second recess when the retaining part is disposed at a retaining position.
