PROBLEM TO BE SOLVED: To provide a motor-driven bicycle having less restriction on the design allowing a simplified configuration of a case mounting part and installed on a frame in such a way that a battery accommodation case does not hinder any passenger getting on and out. SOLUTION: A motor-driven bicycle is equipped with a motor 10, a battery as power supply to the motor 10, battery accommodation case 3 to accommodate the battery, and a case mounting part for mounting of the case 3 on the frame. The case 3 is given a shape to allow mounting in such a way as surrounding the frame, for example the bottom surface being shaped in U-column. |
