Abstract: A bicycle parking rack includes a tray having a stationary wheel engagement structure that engages a bicycle wheel on one side of the center of the wheel. A movable wheel engagement member is arranged to engage the bicycle on the other side of the center of the wheel, to apply a clamping force on the wheel and to maintain the the bicycle in an upright position. The rack may include lower parking stations in which at each lower station the front bicycle wheel is clamped between the wheel engagement structure and the movable wheel engagement member, and upper parking stations in which at each station the rear wheel engages the wheel engagement structure and the front wheel is engaged with the wheel engagement member. At each upper station, the tray is movable between a loading position and a storage position via an elevated track and trolley arrangement.
