Abstract: A bicycle vertical rack contains a base, a support post, and at least one hanging unit. A respective one hanging unit includes a coupling element, a fixing tube, a rotary tube, a resilient element, a defining element, a horizontal plate, and two hooks. The fixing tube includes a through hole. The rotary tube has a movable groove, a recess and multiple cutouts which. An end of a respective one cutout communicates with the recess, a rear end of the rotary tube is received in the fixing tube, and the resilient element abuts against the fixing tube and the rotary tube. The defining element is received in the through hole and the movable groove, an inner wall of the horizontal plate is connected with a front end of the rotary tube, and the two hooks are connected to an outer wall of the horizontal plate.

Abstract: A top tube adaptor contains: a body, two fixers, and a slidable rod. The body includes at least one slot, and a respective positioning rack has multiple teeth. The slidable rod includes a channel and a locking seat for accommodating a rotatable connector. The rotatable connector includes two shafts, a press portion, a button, an orientation segment, an engagement portion, and a first resilient element. A respective fixer includes a curved hook, a cutout, two tabs, a coupling projection, a column, and a second resilient element. The second resilient element has two abutting segments, one of the two abutting segments abuts against the two tabs, and the other abutting segment contacts with or removes from the coupling projection so as to close or open the cutout. The two fixers are connected with two ends of the slidable rod respectively.

Abstract: A vertical bike stand contains: a base, a coupling column, a guide groove, and a positioning rack. The positioning rack includes a toothed section, and the support tube includes a channel. A holder is arranged on the support tube and is configured to close the channel and includes two prongs and a recess. A fixer is fitted on the support tube and is rotatably connected with a connector. The connector includes a shaft rotatably connected with the fixer, a press tab extending from an upper end of the connector, an operation portion extending outward from the press tab, an orientation segment extending into the guide groove from a lower end of the connector, and a paw extending from the orientation segment and configured to engage with the toothed section. The orientation segment is pushed by a first resilient element to fix in the fixer.
