One floating body (4, 5) each is fastened by means of stays (14, 15) to the two forks (1, 2) of a road cycle (3). The first floating body (4) replaces the front wheel and also serves as a rudder by means of a keel (13). The second floating body (5) comes to lie under the rear wheel (6). Via a shaft arranged transversely to the second floating body (5), the rear wheel (6) indirectly drives the rotary spindle (8) of two paddle wheels (7) mounted laterally on this floating body (5). These paddle wheels (7) are advantageously designed as additional floating bodies. <IMAGE>
