Known Bicycle, comprising a frame formed of two parts, connected by a hinge, presented in the form of two loops connected by a horizontal axis, which is perpendicular to the plane of the frame, and fixed with screws, pipes, in front of which is omitted pin front plug with an installed front wheel and the wheel and connected with the back of the rear fork with a rear wheel, a gear wheel which can the AME bracket screw hole (USSR author's certificate 1729897, IPC 62 15/00, 1992).

The disadvantages of this device are complicated structural design due to the large number of parts, and the impossibility of movement in the water body due to the lack of buoyancy.

The closest analogue of the invention is a Bicycle, comprising a frame made of lightweight and durable material in the form of a curved pipe with a sleeve at the upper end, through which is threaded a rod fork with established handlebars and front wheel, flanked by protective flaps attached to the plug, and mounting the housing on the other end, in which is mounted the rear fork rear wheel, seatpost tube with the saddle and pedal drive bevel wheel which chain drive associated with the specified rear wheel, on which by means of the bracket is placed space for cargo (USSR author's certificate, 1221021, CL 62 To 15/00).

The disadvantage of this device is the inability of the movement in the water body due to the lack of buoyancy due to the constructive design.

The objective of the invention is the creation of a bike with greater functionality.

This object is achieved in that the bike frame containing the form and the second actuator, chain transmission, the wheel bracket with space for cargo, according to the invention equipped with two floats, screen, blades and three brackets, with the floats are located on the sides of the rear fork against each other symmetrically to the longitudinal axis of the frame and secured at the ends of the brackets, and brackets attached to the fork of the rear wheel, with one of the brackets is made in the form of a knee, the screen attached to the spokes on one side of the front wheel, the blades are placed inside the rear wheel and fastened with spokes, and Noskova the section of each float made the cut facing to the rear fork and ensuring smooth rotation of the crank with pedals, and the neck has a length ofwhere a is the length of cut from tip float; B is the diameter of the circle described by the ends of rods pedals during the rotation; - the length of the rod to the pedal, and the width G=D+E, where Y is the width of the neck; D is the length of the pedal; E is the distance from the outer end of the pedal to cut on Noskova section of the float.

The proposed bike is illustrated by drawings, where Fig.1 - bike, side view; Fig.2 - bike, top view;
in Fig.3 shows a knee - shaped fastening bracket with floats to the fork;
in Fig.4 is shown established bragano the position of the bike on the water surface.

The Bicycle includes a frame 1 made in the form of a curved pipe with the sleeve and the connector housing made of lightweight and durable material. The stem of the front fork "and" passed through the sleeve of the frame 1 and provided with the wheel.

The front wheel 2 is mounted on bearings fork "and". On the bearings of the rear fork 4 "" rear wheel 3. Two of the float 4, made of a buoyant material such as Styrofoam, are located on the sides of the rear fork "b" against each other and symmetrically relative to the longitudinal axis. The front bracket 5 is made in the form of knee and by means of the fastening material, for example, soft wire, tape, clamps attached to the top surface of the fork "b". The other two brackets 6 are attached to the sides of the rear fork "b" in the above way with the bracket 5. Eight blades 7, made of light material, for example, organic glass vinyl plastic, carbon fiber, placed inside the wheel 3 from each other through 45 and rigidly bonded with knitting needles. Each float 4 corps "to" horizontal hole mounted on brackets 5 and 6 and fixed by screws 8. The rod 9, is made of lightweight and durable material, such as plastic, sealed inside each of the float 4. The screen 10, performed the one side of the wheel 2. In connecting the body frame 1 is mounted seat tube seat, and on each side of the rear wheel bracket with space for cargo (not labeled). On Noskova the section of each float 4 made the cut 11 facing the rear fork "b" length

where a is the length of the neck;
B is the diameter of the circle described by the ends of rods pedals while rotating;
In the length of the connecting rod,
and the width G=D+E;
D is the length of the pedal;
E - the distance from the outer end of the pedal to cut on Noskova site.

The floats 4 can be tightened from the outside a waterproof material, such as rubberized cloth (not shown).

The bike works as follows.

When driving on a paved surface coated interact wheels 2 and 3, connected via the plug "a" and "b" to the frame 1.

Water floats 4 bury in the water under load from the weight of the bike and the operator (Fig.6). During the rotation of the rear wheel 3 blade 7 interact with water and create a pushing force. Thereby, the movement of the bike. While fixing materials provide reliable communication floats 4 and through the body "b" and the brackets 5 and 6 with the rear fork "b" wheel 3.

When the wheel 2 is located in the about 2. If the plug "and" wheels 2 to reject, for example, to the right, in this case, the screen 10 interacts with water in the presence of a large resistance and the bike changes direction of motion, i.e., turns to the right. This mount provides a secure connection of the screen 10 with the spokes of the wheel 2.

The introduction of the floats 4 provide the floodability of the device, i.e. its buoyancy.

The rod 9 gives the rigidity of the float.

The placement of the blades 7 to the inside rear wheel eliminates lateral forces when driving in a straight line.

The execution of the bracket 5 by the shape of the knee increases the rigidity of the suspension of the float.

The placement of the screen 10 with one side surface of the front wheel decreases the weight of the device.

The execution of the bracket 5 by the shape of the knee increases the rigidity of the suspension of the float.

The cutout 11, its length And width G ensure smooth rotation of the crank with pedals.

The location of the floats against each other and symmetrically to the longitudinal axis contributes to the stability of the device on the water.

The invention can be used as a means of transportation by land and water.
