In accordance with the present disclosure, the attachment structure (210) may be detachably coupled to the two-wheeled vehicle (100) by means of mechanical coupling and/or electrical coupling.
[064] When the modular vehicle (1) is required to be converted from the two-wheeled configuration (100) to the three-wheeled configuration (200), the two wheeled configuration (100) (or the two-wheeled vehicle (100)) is removably coupled to the

attachment structure (210). In accordance with an embodiment of the present disclosure, to couple the two wheeled vehicle (100) with the attachment structure (210), the two-wheeled vehicle (100) is re-configured to move the rear portion (104) of the two-wheeled vehicle (100) towards the rear wheel (124) of the two-wheeled vehicle (100), as shown in FIG. 4, such that the rider seat and/or the passenger seat of the two-wheeled vehicle (100) remains substantially horizontal (i.e., parallel to the ground surface or the terrain) in the three-wheeled configuration (200). Subsequently, the two-wheeled vehicle (100) is brought closer to the attachment structure (210) to be received in the second body frame (216), specifically the rear wheel (124) of the two-wheeled vehicle (100) is received on a wheel receiving unit/platform (not shown) of the attachment structure (210), for coupling the two wheeled vehicle (100) with the attachment structure (210).
[065] In accordance with another embodiment of the present disclosure, to couple the two wheeled vehicle (100) with the attachment structure (210), the two-wheeled vehicle (100) is brought closer to the attachment structure (210) to be received in the second body frame (216), specifically the rear wheel (124) of the two-wheeled vehicle (100) is received on a wheel receiving unit/platform (not shown) of the attachment structure (210), for coupling the two wheeled vehicle (100) with the attachment structure (210). Thereafter, the two-wheeled vehicle (100) is re-configured to move the rear portion (104) of the two-wheeled vehicle (100) towards the rear wheel (124) of the two-wheeled vehicle (100), as shown in FIG. 4, such that the rider seat and/or the passenger seat of the two-wheeled vehicle (100) remains substantially horizontal (i.e., parallel to the ground surface or the terrain) in the three-wheeled configuration (200). Subsequently, the wheel receiving unit/ platform of the attachment structure (210) along with the rear wheel (124) of the two-wheeled configuration is moved (or slided) rearwardly towards the seat unit/platform (212). Within the scope of the present disclosure, said re¬configuration of the two-wheeled vehicle (100) is facilitated by the wheel repositioning system (150) of the two-wheeled vehicle (100), provided at the rear end structure (104) thereof.
[066] Similarly, when it is required to convert the modular vehicle (1) from the three-wheeled configuration (200) to the two-wheeled configuration (100), the attachment structure (210) is decoupled from the two-wheeled vehicle (100). In an embodiment, after de-coupling of the attachment structure (210) from the two-wheeled vehicle (100), i.e., after the two-wheeled vehicle (100) is removed from the second body frame (216)

of the attachment structure (210), the two-wheeled vehicle (100) is re-configured to move the rear portion (104) of the two-wheeled vehicle (100) away from the rear wheel (124) of the two-wheeled vehicle (100), as shown in FIG. 2, such that the rider seat and/or the passenger seat of the two-wheeled vehicle (100) is substantially horizontal (i.e., parallel to the ground surface or the terrain) in the two-wheeled configuration (100). In another embodiment, the two-wheeled vehicle (100) may be re-configured to move the rear portion (104) of the two-wheeled vehicle (100) away from the rear wheel (124) of the two-wheeled vehicle (100), as shown in FIG. 2, and subsequently, the two-wheeled vehicle (100) is removed from the second body frame (216) of the attachment structure (210) to decouple the attachment structure (210) from the two-wheeled vehicle (100). Said re-configuration of the two-wheeled vehicle (100) is also facilitated by the wheel repositioning system (150) of the two-wheeled vehicle (100), provided at the rear end structure (104) thereof.
[067] Referring to FIGS. 2 to 4, the wheel repositioning system (150) of the two-wheeled vehicle (100) or the modular vehicle (1) is shown.
