Abstract: The rack according to the present invention is adapted to support, in an upstanding position, a variety of bicycles having wheels of different widths and diameters. The rack includes a bottomless funnel-shaped channel having a pair of spaced parallel walls and a pair of tapered walls. The channel is supported at both ends by a longitudinal beam for raising the channel above the ground. A pair of guiding rails are mounted above the channel and fixed parallel to the tapered walls. The guiding rails have a generally trapezoidal shape. The parallel walls laterally support the bicycle having narrow wheels along their lower segment and vertically support the wheel at both ends of the segment. The bicycle with wider wheels are vertically supported by the tapered walls which slightly squeeze the elastic tires of the wheels. These latter bicycles are held in an upstanding position by the guiding rails which are close to the spokes and allow a nearly nil tilt of the bicycle.
