The present invention relates to an amphibious bicycle. The three-wheel type amphibious bicycle comprises: a main body which has a streamlined housing shape; a canopy which is installed at part of the top surface of the main body in order to be opened or closed; a pair of front wheels which is included in the front side of the main body; one back wheel which is included in the back side of the main body; a driven sprocket which is included on the front wheel axis where the front wheels are fixated; a driving sprocket which is fixated to the inside of the main body at an interval from the driven sprocket and has a pedal; and a chain which connects the driving sprocket and the driven sprocket. The amphibious bicycle further comprises: an installation protrusion unit which protrudes from the bottom of the main body higher than the draft of the main body; a reverse-T shaped installation guide which has an inserting end that is inserted and welded into the installation protrusion unit from the bottom of the main body in a single body, and a horizontal end that is connected with the inserting end at a right angle in order to insert the front wheel and is welded to the bottom of the main body, and where the driven sprocket is placed inside a point where the inserting end and the horizontal end meet; a pair of bearings which is fixated to the inside of both ends of the installation guide and is supported to be able to rotate by inserting the front wheel axis; and a sealing member which seals both ends of the installation guide in the outer side of the bearing. According to the present invention, the amphibious bicycle can improve safety including driving safety, can remove inconvenience during amphibious use, can provide excellent riding quality by performing amphibious driving in a state of being mounted inside the housing closed by the canopy, can provide beautiful appearances, and can contribute in creating new leisure cultures by removing concerns over leakage through a driving unit. |
