Portable apparatus for using bicycles as a type of watercraft

A portable apparatus for using a bicycle not only on land but also as a type of watercraft, comprising two oblong inflatable floats;

• means for connecting said floats with one another;
• means for securing a bicycle to said means for connecting between said floats;
• means for driving the apparatus with a propulsion unit including a propeller and a clutch unit picking up a motion from a tire of a bicycle rear wheel, said means for connecting said floats and for securing the bicycle including a rear joint device for connection between rear parts of said floats and rear upper and lower forks of the bicycle, and a front joint device for connection a front of said floats with a lower bar of a bicycle frame, a horizontal directional arm fixed by a vertical rotation joint to said front joint device, a second vertical rotation joint provided at an end of said arm with a clamp arranged at a top of said joint to feed onto a rim with a tire of a front wheel of the bicycle, a connecting element fixed to said clamp for a propulsion unit with said propeller, a quick-coupling clamp to which said clutch unit is fixed and which is securable to a bar of a saddle of the bicycle frame and connected to said propulsion unit by a flexible shaft with two heads one at each end so that by turning of pedals and therefore a rear wheel of the bicycle, movement is transferred through said flexible shaft to said propulsion unit, while at the same time using a bicycle handlebar to rotate an axis of a front fork that supports the front wheel a rotation of said propulsion unit using the handlebar is determined through said rotation joints between said front joint device and said directional arm and between said arm and said clamp for the front wheel of the bicycle, to make the watercraft change direction as desired, said means for connecting said two floats, said means for securing the bicycle, and said means for driving being formed so that the apparatus is stowable inside shoulder packs and rucksacks for easy transport while riding the bicycle or carrying it by hand.
