Firstly, the user/rider brings the first body frame (101) towards the second body frame (102) such that the rear ground engaging member (8) of the first body frame (101) is received at the supporting platform (21) and the supporting platform (21) rotates about the pivot axis at some extent to hold the rear ground engaging member (8) in the slider (20) of the second body frame (102), as shown in Figure 1. Then, the user/rider operates the first actuator to actuate the repositioning unit (30). The first actuator actuates the suspension link (34) to pivot relative to the suspension member (33), thereby moving the rear portion (130) of the first body frame (101) towards the rear ground engaging member (8) of the first body frame (101), as shown in Figure 7. Subsequently, the user/rider operates the second actuator to actuate the slider (20). Upon actuation of the slider (20), the slider (20) slides the rear ground engaging member (8) of the first body frame (101) over the pair of rails (23) from the first position (A) to the second position (B), as shown in Figure 9.

Alternatively, the slider (20) may be rotatable to move (rotate) the rear ground engaging
member (8) along with the lifting arm (40) from the folded position to the unfolded
position. Further, the user/rider operates the third actuator to actuate the lifting arm (40).
Upon actuation, the lifting arm (40) is pushed against the ground surface, to lift the second
body frame (102) to align the second body frame (102) with the first body frame (101),
as shown in Figure 13. Alternatively, upon actuation, the lifting arm (40) is pushed against
the ground surface, to lift the first body frame (101) and the second body frame (102) for
alignment between the first body frame (101) and the second body frame (102).
Furthermore, the user/rider operates the fourth actuator to actuate the engagement unit
(50) such that the one or more pins (51) of the second body frame (102) are received in
the holes (52) of the first body frame (101) to couple the second body frame (102) with
the first body frame (101), as shown in Figure 15. Subsequently, the user/rider operates
the third actuator to lift the lifting arm (40) from the ground surface, after coupling the
second body frame (102) with the first body frame (101), as shown in Figure 13.
[00064] Similarly, when the modular vehicle (100) is required to be converted from
the three-wheeled configuration to the two-wheeled configuration. The first body frame (101) of the vehicle (100) is required to be decoupled from the second body frame (102) of the vehicle (100). Firstly, the user/rider operates the third actuator to actuate the lifting arm (40) to support the front portion of the second body frame (102), as shown in Figure 13. Further, the user/rider operates the fourth actuator to actuate the engagement unit (50) to disengage the one or more pins (52) of the second body frame (102) from the holes (52) of the first body frame (101), as shown in Figure 14. Subsequently, the user/rider operates the third actuator to actuate the lifting arm (40) to lift the lifting arm (40) from the ground surface, thereby lowering the second body frame (102), as shown in Figure 12. Alternatively, the slider (20) may be rotatable to move (rotate) the rear ground engaging member (8) along with the lifting arm (40) from the unfolded position to the folded position. Further, the user/rider operates the second actuator to actuate the slider (20) to slide the rear ground engaging member (8) of the first body frame (101), over the pair of rails (23), from the second position (B) to the first position (A), as shown in Figure 8. Further, the supporting platform (21) of the slider (20) rotates about the pivot axis at some extent to release the rear ground engaging member (8) of the first body frame (101)

from the second body frame (102), as shown in Figure 6. Furthermore, the user/rider operates the first actuator to actuate the suspension link (34) to pivot relative to the suspension member (33) to move the rear portion (130) of the first body frame (101) away from the rear ground engaging member (8) of the first body frame (101), as shown in Figure 2.
[00065] In an embodiment, wherein the first actuator, the second actuator, the third
actuator and the fourth actuator may be controlled manually by the user/rider to operate the repositioning unit (30), the slider (20), the lifting arm (40), and the engagement unit (50) to convert the modular vehicle (100) from the two-wheeled configuration to the three-wheeled configuration or from the three-wheeled configuration to the two-wheeled configuration.
[00066] In an alternate embodiment, the first actuator, the second actuator, the third
actuator and the fourth actuator may be controlled by the control unit. The control unit
may be actuated by single switch. The user/rider may operate single switch to control the
first actuator, the second actuator, the third actuator and the fourth actuator for converting
the vehicle (100) from the two-wheeled configuration to the three-wheeled configuration
or from the three-wheeled configuration to the two-wheeled configuration.
[00067] The present disclosure discloses the modular vehicle (100) which can be
easily converted from a two-wheeled vehicle to a three-wheeled vehicle and vice versa
according to the requirements. The actuation of the slider (20), the repositioning unit (30),
the lifting arm (40) and the engagement unit (50), upon being actuated by the one or more
actuators (60), allows convenient conversion of the modular vehicle (100) from the two-
wheeled configuration to the three-wheeled configuration and/or from the three-wheeled
configuration to the two-wheeled configuration, thereby reducing the assembly time.
