Abstract

A motor-assisted bicycle (10A through 10E) includes an assistive motor (66) for generating a drive force to assist in a pedalling force applied by a rider to pedals (52L, 52R), a battery module (128, 240, 282, 312) including batteries (142) as a power supply for the assistive motor (66), and an alarm buzzer (22) mounted in the battery module (128, 240, 282, 312). An alarm sound generated by the alarm buzzer (22) is emitted in a forward direction of the motor-assisted bicycle. Thus, a rider of the motor-assisted bicycle can seek attention of people walking in the vicinity of the bicycle by producing an alarm sound.

Description

technical field [0001] The present invention relates to an electric assist bicycle having an alarm buzzer that emits an alarm sound. Background technique [0002] In Patent Document 1 shown below, a vehicle body cover type electric power assist bicycle is proposed, when the vehicle speed detected by the vehicle speed sensor becomes a predetermined value or more, from the rear surface of the seat back where the rider sits The speed warning buzzer emits a warning sound to call the rider to operate the brakes and activate the brake motor to suppress an excessive increase in vehicle speed. [0003] Patent Document 1: JP-A-2005-297640 [0004] However, in the technology described in the above-mentioned Patent Document 1, although the speed warning buzzer is provided on the back side of the back in the vehicle body cover, it is not ideal to arrange the electrical components on the back. At this time, since the speed warning buzzer is far away from other electrical components (fo...
