Apparatus for towing bicycles, comprising a towing arm, a connector, adapted to fix the towing arm to a towing vehicle, a joint for interconnection between the towing arm and the connector, which defines a first oscillation axis and a second oscillation axis, the first oscillation axis being parallel to the resting surface of the towing bicycle to which the connector is coupled during use, a fork for connection of the towing arm to the hub of the front wheel of the bicycle to be towed, the fork being locked to the towing arm during use, a strut pivoted on the towing arm, and a coupling assembly which is adapted for connection of the strut to the bicycle to be towed. The first oscillation axis is transverse to the anteroposterior direction of the towing bicycle and the second oscillation axis is perpendicular to the resting surface.

1. An apparatus for towing bicycles, comprising: a towing arm;a connector, which is adapted to fix said towing arm to a towing vehicle;a joint for interconnection between said towing arm and said connector, which defines, for said towing arm, with respect to said joint, a first oscillation axis and a second oscillation axis, said first oscillation axis being substantially parallel to the resting surface of a towing vehicle to which said connector is correctly coupled during use, said first oscillation axis being furthermore substantially transverse to an anteroposterior direction of the towing vehicle, said second oscillation axis being substantially perpendicular to said resting surface;a fork for connection of said towing arm to a hub of a front wheel of the bicycle to be towed, locking means for locking said fork to said towing arm in order to jointly connect said fork and towing arm during use, wherein the fork is pivoted to said towing arm along a third oscillation axis which is substantially parallel to said first oscillation axis, said fork comprising: two secondary arms provided on opposite sides of a first end of said towing arm, a second end of said towing arm being adapted to be connected to the towing vehicle by way of said connector,a pivot, which passes through said first end and through said secondary arms so as to connect said first end and secondary arms, defining said third oscillation axis,wherein said locking means are interposed between said secondary arms and said towing arm and comprise: first blocks jointly connected to said secondary arms,second blocks jointly connected to said towing arm,fastening means for a mutual fastening of said first blocks to said second blocks; androtation contrasting means for contrasting mutual rotation of said first blocks with respect to said second blocks when said first and second blocks are fastened by said fastening means; anda strut pivoted on said towing arm, a coupling assembly being provided which is adapted for connection of said strut to the bicycle to be towed. 2. The apparatus of claim 1, wherein said strut is pivoted to said towing arm along a fourth oscillation axis which is substantially parallel to said first oscillation axis. 3. The apparatus of claim 2, wherein said coupling assembly is pivoted to said strut so as to oscillate about a fifth oscillation axis, which is substantially parallel to said fourth oscillation axis. 4. The apparatus of claim 3, wherein said coupling assembly comprises a flange for pivoting to said strut and brackets for fixing to a head tube of a frame of the bicycle to be towed, said coupling assembly, connected to the head tube, determining a substantially perpendicular arrangement between said fifth oscillation axis and the longitudinal axis of said head tube. 5. The apparatus of claim 1, wherein said secondary arms have engagement seats for the ends of the hub of the front wheel of the bicycle to be towed, said engagement seats being provided at a first end of said secondary arms which lies opposite to a second end thereof which is pivoted to said towing arm. 6. The apparatus of claim 5, comprising clamping means for clamping said secondary arms toward each other, for a clamping thereof on said hub when said ends of said hub are inserted in said engagement seats, for a stable mating of said hub with said fork. 7. The apparatus of claim 1, wherein said strut comprises two parallel elements which are connected, at opposite ends thereof, to said towing arm and to said coupling assembly.
