The invention relates to a device making it possible to receive, without adjustment, any type of bicycle for training in pedalling with a fixed post. It consists, on the one hand, of a fastening head (1) ensuring the immobility of the front wheel for holding the cycle by means of two base stirrup pieces (2) and a third telescopic upper stirrup piece (3). The profile of these three stirrup pieces is provided with at least two different spokes (radii) for receiving all sizes of bicycle tyre. And, on the other hand, a movable carriage (7) supporting rollers (8) which are displaced on a frame (9) by means of four castors (rollers) (6), the mobility of this carriage permitting the instantaneous self-centering of the rollers (8) as a function of the different positions of the rear wheel. <IMAGE>
