The present invention relates to a water bicycle, and more particularly, by installing a timing pulley on the bicycle to transmit power through the timing belt, it is possible to move forward and backward, and install a propeller on the rear wheel to improve the driving force and prevent safety accidents. That is about water bikes.

Ordinary bicycles are used for leisure in the city or in the mountains, and are divided into general use and mountain use, and are manufactured by using aluminum alloy, especially for light and strong durability. In addition, a folding bicycle has been developed and distributed for carrying and easy carrying, and a bicycle for rotating a wheel by generating a rotational force by a propeller such as an electric motor using a storage battery has been spreading.

Recently, as the population seeking to enjoy leisure has increased, the demand for leisure bicycles is increasing, and in particular, the need for water bicycles that can be used in water, such as rivers, lakes and the sea, has emerged.

In general, water bicycles are formed to ride on rivers, lakes, and seas, such as general-purpose bicycles, buoyancy bodies in the form of air tubes, supports for connecting and supporting the bicycles, propellers for generating propulsion, Power transmission means for transmitting the rotational force of the wheel to the propeller, steering means for changing the direction and the like.

However, the conventional water bicycle has a complicated structure and a complicated assembly and disassembly process at the time of change of use, and in particular, the power transmission to the propeller is geared, so that the force due to the change of the propeller's angle is reversely transmitted to the wheel during the change of direction. There was a problem such as a disconnection of the driving force.

The conventional water bicycle using a general bicycle, a number of people need to be moved during the movement because a number of people to move to the water in the state in which the buoyancy device is coupled to the bicycle, or on the contrary, several people must enter and move from the water to the land. There was a problem that back movement is inconvenient.

In addition, a water bicycle using a general bicycle can move forward but cannot move backward. Therefore, a water bicycle using a general bicycle has a problem in that it is impossible to stop or reverse the water bicycle in order to avoid this when obstacles suddenly appear when driving forward from the water.

Therefore, in some cases, it is possible to move forward and backward by additionally installing a transmission as a power transmission means, but since the transmission must be additionally installed, there is a problem in that the manufacturing cost increases and the load of the water bicycle increases to decrease the power efficiency.

In addition, the conventional water bicycle formed with a structure for generating a propulsion force by installing a propulsion unit on the front wheels has the inconvenience that the occupant is wet with water by jumping water by the propulsion unit installed on the front wheels.

The buoyancy body of the conventional water bicycle is formed as a tube type for injecting air, and if the buoyancy body is damaged by stones or branches while driving in the water, there is a risk of safety accident due to air leakage. In this case, there was a problem that the water bicycle was distorted from side to side while driving because the left and right side buoyancy bodies were not balanced, and there was a risk of a safety accident such as slipping and floating on the buoyancy body during the boarding and disembarkation of the occupant.

In the case of the propeller of the conventional water bicycle, the driving shaft of the upper part and the driven shaft of the lower part are formed to cross vertically to drive the belt type, so that the belt is frequently disengaged from the pulley by transmitting power in a twisted state, Frequent contact between the ascending belt and the descending belt promotes wear of the belt, which shortens the life of the belt.

The present invention has been made in order to solve the above-mentioned conventional problems, it is possible to move forward and backward by installing a timing pulley on the bicycle to transmit power through the timing belt, install a propeller on the rear wheel to improve the driving force and safety accidents Its purpose is to provide a water bike that can be prevented.
