PURPOSE: A front wheel drive apparatus of a bicycle is provided to minimize the consumption of physical energy of a rider by 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 hub-mount shaft, 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 unidirectional rotation power delivered to a front wheel(5). The crank arm is rotated when a user steps on pedals(40). The hub-mount shaft is connected to the hub(6) of the front wheel and projected to the right and the left. The front wheel drive part is axially connected to the hub-mount shaft and drives the front wheel 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 allow the front wheel to generate a propulsion force according to the rotation of the front wheel drive part.
