The trunk capacity and cabin storage space far surpass that of a typical two-wheeler, making its practicality top-class.
The AR3, which features a large rear compartment, is a widely adopted vehicle model used by postal services in Singapore. Like the AD3, it is a three-wheeled vehicle, but with a configuration of one wheel in the front and two in the rear, and it also includes a reverse gear.

AR3 Adopted by Singapore Post (2014)
■In Singapore where the labor force is tight, the ability to transport huge cargo was a key factor that led to the AR3 being purchased by the Singapore Post Office in 2011.
■At present, this vehicle model has gradually replaced the old postal vehicle model of the country’s post office.
■As of 2015, ADIVA has delivered 250 AR3 units to the Singapore Post Office.
