The unit includes a rotatable bicycle storage carousel that is structured to rotate about a central axis to provide for a dense storage of bicycles, which are stored on the rotatable bicycle storage carousel in a generally vertical orientation. The unit further includes an enclosure surrounding the carousel. The rotatable bicycle storage carousel comprises an elongated central core oriented in a first direction that is orthogonal relative to a plane defined by a base structure of the rotatable bicycle storage carousel.
