(JP11079064-A)   NOVELTY - The bicycle has a driving section driving the wheel and a battery supplying electric power to this section. A battery case (10) is loaded with the battery and mounted onto the bicycle main frame and has a transversal cross section with a recess (10c) to cover part of an outer surface of the main frame. A part of the battery is inserted into an inner space on each side of this recess.    USE - For utilizing driving power of motor for assisting human driving power.    ADVANTAGE - Provides improved facility for riding on and off the bicycle by disposing the batteries separately to surround the main frame to provide less protuberance on each side. Allows side of battery case facing away from main frame, to be shaped like an arc or to have smaller width. Allows front or upper side of battery case to have a smaller width. Has a battery configuration with good space utilization efficiency by evading the chain case if the battery case is to be disposed near the standing pipe. Has battery case without exposing connector section to outside, thereby eliminating need for a cap for covering the connector section, reducing the number of components in the bicycle and providing a good appearance.
