Nautical arrangement permitting bicycle to be driven on water without any modification - includes light chassis fixed to connected floats carrying propeller roller driven from cycle rear wheel with front wheel steering

摘要

The cycle is supported and fixed (3) on a light detachable chassis (1), joining two floats (13). The cycle rear wheel drives a roller (7), spring loaded to it, connected by gearing to a propeller (11). Propeller direction is controlled by the front wheel position, as in normal road use, joined to a rod (5) and the propeller pivot. In the event of shocks, the propeller raises automatically, without interrupting pedalling. The cycle frame is fixed to the chassis by two bars (2), with rapid fixings (3). The chassis may be of aluminium alloy, steel or composite. USE/ADVANTAGE - Sport or excursion use. Easy and quick to fasten and use or transport. Speed is proportional to rear wheel motion.
