The present invention relates to an amphibious bicycle, and more particularly is able to ride the bike like a regular land as well as sea, rivers, the present invention relates to amphibious bicycle that allows the boat to ride as a substitute. ; According to one embodiment of the amphibious bicycle according to the present invention, and at least one of the front and rear wheels, pedal and the chain that drives the rear wheels, and the body is configured as a frame for supporting the connection of each element, including a handle, comprising a bicycle according to amphibious buoyant pipe is releasably attached to the bottom on both sides of the body, the at least one or more is mounted on the front wheel steering member to enable the steering according to the direction in response to the operation of the handle, the at least one rear wheel to be rotated to the fixed driving force transmission to the vehicle body frame, the mounting frame and the pedal to the driving force transmission for transmitting a driving force by the driving force transmitting frames the first sprocket, wherein the engine is disposed on one side of the vehicle body, on one side of the second sprocket gear, and the driving force transmission frame for transmitting a driving force to the driving force transmitting frames according to the engine connection is to provide an amphibious bicycle comprising a screw for generating a driving force by receiving a driving force rotates. ; In addition, according to another embodiment of the present invention, and at least one of the front and rear wheels, the rear wheels and chain drive for pedal, the vehicle body is configured as a frame for supporting and connecting the elements, including the handle, is mounted in the amphibian bicycles comprising a buoyant pipe to be desorbed at the bottom on both sides of the body, the at least one front wheel is attached to the mounting to the steering member, the at least one rear wheel to be rotated to secure the driving force transmission to the vehicle body frame, the driving force transmitting frames to enable the steering according to the direction in response to the operation of the handle and by the pedal a driving force with the first sprocket, wherein the engine is disposed on one side of the vehicle body, a second sprocket and a predetermined mutual distance on the driving force transmission frame for transmitting a driving force to said driving force transmission frame by said engine for transmitting the driving force transmitting frames mounting and, at the same time rotating with the rotation of the driving force transmitting frames to provide amphibious bicycle comprising the aberration with a plurality of projecting surface so as to generate a driving force. ; Therefore, simple and easy to float the pipe and so readily available to use the land for commercial or converted without complex assembly and disassembly operations by removably mounted to the outside of the bike bodywork, using amphibious without stepping on the pedal, the engine according to the present invention, on land or water there is an effect that can ride a bike.
