Abstract
A motor-assisted bicycle includes an assistive motor, a battery module, and an alarm buzzer. The assistive motor is to generate a drive force to assist in a pedaling force applied by a rider to pedals. The battery module includes batteries as a power supply for the assistive motor. The alarm buzzer is mounted in the battery module to generate an alarm sound. The alarm sound generated by the alarm buzzer is emitted in a forward direction of the motor-assisted bicycle.

A motor-assisted bicycle comprising:
- an assistive motor to generate a drive force to assist in a pedaling force applied by a rider to pedals;
- a battery module including batteries as a power supply for the assistive motor;
- an alarm buzzer mounted in the battery module to generate an alarm sound, the alarm sound generated by the alarm buzzer being emitted in a forward direction of the motor-assisted bicycle;
- a case member housing the battery module and the alarm buzzer in the case member;
- a head tube supporting a steering shaft to steer a front wheel;
- a joint tube joined to the head tube, the case member being mounted on the joint tube, the joint tube having an inlet opening defined in the joint tube to introduce the alarm sound generated by the alarm buzzer into the joint tube, the head tube having sound radiating holes defined in the head tube to radiate the alarm sound propagated through the joint tube into the head tube in the forward direction of the motor-assisted bicycle;
- and
- a cover disposed on the head tube, to prevent foreign matter from being introduced through the sound radiating holes into the head tube.
