BACKGROUND
[0002] Vehicles such as, but not limited to, motorized scooters, motorcycles, etc.,
among other components and assemblies include body frame, a power unit, a passenger seating area, and wheels. The power unit is adapted to provide the necessary power to the wheels, to drive the vehicle. The power unit, seating area, etc., are all carried by the body frame. The wheels are connected to the body frame. Therefore, the body frame is designed to carry the load of the vehicle, including the weight of the power unit, other components, and sub-assemblies of the vehicle. Such weight carried by the body frame is transferred, through the wheels to the ground.
[0003] In addition to weight of the power unit, battery modules, other components
and sub-assemblies of the vehicle, the body frame is also required to hold and sustain loads of occupants of the vehicle, attachments to the vehicle, and articles carried by the vehicle. The effect of these loads on the vehicle often appears more detrimental or demanding for the body frame when the vehicle is operational. Therefore, it is often seen that few body frames get damaged during usage thereof, owing to the limitation associated with handling and managing the loads applied thereon. The major limitation of the conventional body frames of the vehicle is its strength, torsional stiffness or bending stifnesss.
[0004] The present disclosure is directed to overcome one or more limitations
stated above or any other limitations associated with the conventional vehicles.

Therefore, it is intended that the present disclosure covers such modifications and variations provided they come within the ambit of the appended claims and their equivalents.
[00038] Equivalents:
[00039] With respect to the use of substantially any plural and/or singular terms
herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.
[00040] It will be understood by those within the art that, in general, terms used
herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as "open" terms (e.g., the term "including" should be interpreted as "including but not limited to," the term "having" should be interpreted as "having at least," the term "includes" should be interpreted as "includes but is not limited to," etc.).

It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases "at least one" and "one or more" to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles "a" or "an" limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases "one or more" or "at least one" and indefinite articles such as "a" or "an" (e.g., "a" and/or "an" should typically be interpreted to mean "at least one" or "one or more"); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of "two recitations," without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to "at least one of A, B, and C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B, and C" would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances, where a convention analogous to "at least one of A, B, or C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B, or C" would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase "A or B" will be understood to include the possibilities of "A" or "B" or "A and B." While various aspects

and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope being indicated by the following claims.
