  • Publication number: 20170334511
    Abstract: An adjustable bicycle shoe cleat is provided which is fixed to a bottom plate of a bicycle shoe, wherein the bottom plate is provided with two combining holes. The adjustable bicycle shoe cleat includes a cleat body and a fastening assembly. The cleat body has a front engaging end and an opposite rear engaging end. Two adjusting bores are symmetrically and transversely disposed between the front engaging end and the rear engaging end. Each adjusting bore has a small arch section and a large arch section. The two small arch sections are disposed face to face. The fastening assembly passes through the two adjusting bores by two screw members for loosenably screwing the cleat body to the two combining holes, such that the cleat body is able to be biasedly positioned against the bottom plate, facilitating the adjustment of the shoe cleat against the bicycle shoe.

  • Publication number: 20150298762
    Abstract: A bicycle pedal which is rotatably installed on a bicycle crank includes a main body, a pedal axle, at least a fixing rod, and a bushing unit. Therein, the main body has with an axle bore and at least a through hole extending from the outer periphery of the main body and connected with the axle bore. The pedal axle has a first end combined to the crank and a second end inserted in the axle bore, whereby the main body is allowed to rotate against the pedal axle. The fixing rod is removably disposed in the through hole and interferes with the movement of the pedal axle for preventing the main body from being relatively separated from the pedal axle. The bushing unit is disposed between the main body and the pedal axle.

  • Patent number: 8875862
    Abstract: A ratchet hub using a magnetic force for restoration as disclosed has a freewheel unit and a ratchet ring thereof forming a unidirectional ratchet mechanism and a magnetic assembly using a magnetically repulsive force to normally make the freewheel unit and ratchet ring engage mutually and allow force transmission therebetween. Once a force disengaging the freewheel unit from the ratchet ring surpasses the magnetically repulsive force, the ratchet ring is pushed away from the freewheel unit. When the force disengaging the freewheel unit from the ratchet ring disappears, the magnetically repulsive force automatically and promptly returns the ratchet ring to engage with the freewheel unit again.

  • Publication number: 20130180355
    Abstract: A modularized bicycle pedal includes a pedal body and a shaft module. The pedal body has a connecting side provided with a socket portion. The shaft module includes a circular enclosure, a shaft core and plural rolling units. The enclosure has a circular inner surface that defines a through hole. The enclosure is received in the socket portion and coupled to the pedal body. The shaft core partially protrudes into the through hole. The shaft core has a connecting segment and a first sustaining segment. The connecting segment is configured to connect the crank. The rolling units are rotatably sandwiched by the circular inner surface and the first sustaining segment, so that the shaft core is allowed to rotate with respect to the enclosure against an axis.

  • Publication number: 20130125702
    Abstract: A racing pedal for a track bicycle includes a pedal body, a clamping unit and a primary strap. The pedal body has a first end, a second end and an axle near the first end. The clamping unit is movably attached to the first end of the pedal body and pivotable against the axle between a clamping position for engaging a shoe cleat and a releasing position. The clamping unit has a pulling portion and a clamping portion wherein the pulling portion is farther from the second end of the pedal body than the clamping portion is, and when the clamping unit pivots on the axle, upward tilt of the pulling portion makes the clamping portion point downward. The primary strap is positioned in the pulling portion for being looped to receive the shoe.

  • Publication number: 20130025993
    Abstract: A bicycle hub assembly includes a hub body mounted around an axial core. The hub body has one end containing a ratchet ring that has an inner periphery formed with unidirectional ratchet teeth. A ratchet wheel is arranged between the axial core and the ratchet ring and has an outer periphery formed with detent recesses, each said detent recess receiving therein a detent for engaging with the ratchet teeth. The detent includes a pivot portion and a swinging arm. The pivot portion is retained by the detent recess and has an arc of 180 to 270 degrees so that the swinging arm swings when the pivot portion rotates in the detent recess. The detent has clenching surfaces for engaging with the ratchet teeth, wherein a direction where the clenching surface extends is identical to a swinging direction of the swinging arm.

  • Patent number: 8292316
    Abstract: A set of angle-adjusting head parts includes upper and lower head parts respectively mounted on top and bottom ends of a bicycle's head tube holding a front fork stem. The upper head parts include an upper bearing cup having an axially extending oval slot and two retaining surfaces arranged parallelly with the major axis of the oval slot at laterals, an upper bearing having an eccentric slot for receiving the front fork stem and an eccentric seat for engaging into the oval slot, and an adjusting washer mounted in the upper bearing cup and movable along the minor axis of the oval slot and having a circular opening for receiving the upper bearing. Rotating the upper bearing forces the eccentric seat to stop against the retaining surfaces and synchronously move the adjusting washer along the major axis of the oval slot, thereby biasing the angle of the front fork stem.
