Disclosed is a front wheel driving type bicycle. According to the present invention, the front wheel driving type bicycle includes: a bicycle frame; a driving sprocket installed in a rotation shaft supported by a fork of the bicycle frame; a driving sprocket rotating by pedaling; a crank arm rotating the rotation shaft and the driving sprocket by the pedaling; a rotation body supported on the fork to receive power from the driving sprocket and transfer the power to a front wheel; a shaft of the rotation body; a driven sprocket rotating by receiving the power from the driving sprocket; and a wheel rotating by receiving the power of the rotation body, wherein a tire is mounted on the wheel. The front wheel driving type bicycle obtains a driving force by concentrating pedaling power to the front wheel and enables composition of a foldable bicycle, wherein the whole length of the bicycle is shortened or the bicycle frame is folded or unfolded, by concentration of driving devices in the front wheel. The front wheel driving type bicycle also provides safety to prevent a user from falling down by lowering the center of a posture.
