Abstract: A bicycle parking structure is disclosed which has a central column constituted by, or including, a circular array of vertically extending channels which are open radially outwardly so that the front wheel of a bicycle can be wheeled into, and then rolled up each channel. At an elevated position there is a plurality of supports for hooking under the rims of the front wheels of bicycles that have been rolled up the channels. The supports extend outwardly from the column and each support is L-shaped with one of its limbs lying generally tangentially with respect to the column and radially outwardly of the channels.
