ABSTRACT:
A kind of electric power-assisted bicycle is presented in the invention. Its characters consist in that: the electric-driving device 2 is composed of the flat motor installed in the shell and harmonic reducer; the shell body and storage battery are fixed in the middle of the frame; its center shaft crosses the flat motor and the harmonic reducer along with the axis line separately, and can rotate relatively to them; the mentioned flat motor is connected with the power-transmitting device through the harmonic reducer. The entire bicycle is lightweight and long-life, while it is also energy saving high efficient and can be conveniently assembled, used, carried and maintained.
