ABSTRACT:
A power assist bicycle includes a front wheel and a rear wheel, a bicycle body frame supporting the front and rear wheels to be rotatable, a saddle mounted to the bicycle body frame on which a rider rides, and a pair of pedals which are operatively connected to each other through a crank shaft, and the bicycle body frame includes a head pipe supporting the front wheel, a main pipe extending obliquely downward in a rearward direction from the head pipe, and a saddle pipe supporting the saddle at an upper end portion thereof in a standing attitude of the bicycle. The main pipe and the saddle pipe have lower end portions which are connected to each other through a power unit so as to define a leg space having substantially a V-shape therebetween through which a leg of the rider moves when getting on or off from the saddle, and a battery unit having a rectangular parallelopiped shape is also arranged so as to be operatively connected to the power unit at a lowest position of the V-shaped leg space so as to extend in a horizontal direction of the bicycle.
