PURPOSE: A front wheel drive apparatus of a bicycle is provided to facilitate the operation of a bicycle handle by smoothly transmitting the driving force by the rear wheel to the front wheel through a wire. CONSTITUTION: A front wheel drive apparatus of a bicycle comprises a power generator(100), a front wheel drive part(200), a rotation power transmission wire(300), and a plurality of wheel fixing members(400). The power generator is axially connected to a crank shaft(20) rotated according to the rotation of a crank arm(30) and simultaneously generates a driving force of a rear wheel(7) by the rotation of the crank shaft and a unidirectional rotation power delivered to a front wheel(5). The crank arm is rotated when a user steps on pedals(40). The front wheel drive part is connected to the hub(6) of the front wheel and provided with the unidirectional rotation driving force. One end of the rotation power transmission wire is coupled to the power generator while the other end is coupled to the front wheel drive part, so that the rotation power transmission wire transmits the unidirectional rotation driving force created by the power generator to the front wheel drive part in order to rotate the front and rear wheels in a specific direction at the same time. The wheel fixing members, in which a bearing is formed on an end, fix the front wheel in the right position so that the front wheel generates a propulsion force according to the rotation of the front wheel drive part.
