Description

Bicycle including electric module and indoor/outdoor bicycle including same {BICYCLE COMPRISING ELECTRIC MODULE AND BICYCLE FOR INDOOR-OUTDOOR INCLUDING THE SAME}

The present invention relates to a bicycle including an electric module and an indoor/outdoor bicycle including the same.

In general, bicycles are one of the means of short-distance transportation, and have recently been widely used for exercise or hobbies for purposes such as health. It is becoming difficult to store bicycles like this due to narrow residential spaces due to rapid urbanization and population concentration. In addition, as green space gradually decreased, there was a problem of having to transport bicycles far distances in some cases for outdoor hobby activities. Accordingly, folding bicycles have been released that facilitate storage and transportation of the bicycle by allowing the bicycle to be folded or unfolded as needed. These folding bicycles are equipped with a generator that converts the rotational force of the pedals by the user into electrical energy, an electric motor driven to rotate the wheels, and a battery that provides power to the electric motor and stores the electrical energy converted by the generator. Nevertheless, due to limitations in the types of bicycles that can be used indoors and outdoors, separate bicycles had to be provided, and in this case, the problem of ease of storage significantly deteriorates.
