Description

Motorcycle with a motorcycle body

Technical Field

The invention relates to the field of motor vehicles, in particular to a motorcycle.

Background

The motorcycle is used as a common vehicle, and provides great convenience for people to go out; since a motorcycle is a vehicle to which a human body is exposed, it is required that a helmet must be worn to reduce a risk factor.

In actual use, when the vehicle stops, the helmet needs to be placed, and the helmet is usually placed in an additional carrying case or directly hung at a certain position of the vehicle. For the electric motorcycle, the motorcycle type is less, and the loading object box can increase the cost in addition, simultaneously, can make whole car structure seem huge complicated. The storage box is small in volume, can only be used for placing a helmet, cannot be used for placing other articles, and is very inconvenient to use when two helmets are needed or other articles are needed in a large number of times.

Therefore, in order to solve the above problems, it is necessary to improve the existing motorcycle, and the structural arrangement can increase the volume of the storage box of the motorcycle, place more articles, and increase the convenience of the user.

Disclosure of Invention

In view of this, the present invention is directed to overcome the drawbacks of the prior art, and provides a motorcycle, which is structurally configured to increase the volume of a storage box of the motorcycle, to accommodate more objects, and to increase user convenience.
