  "textContent": "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.",
