 Rats Night of Terror (1984)

aka

Rats - Notte di terrore 

One hundred years after a nuclear war has devastated the planet, society 

has been reborn into two factions; the underground society and the scavengers 

above in the wastelands. A group of scavengers on bikes come across a town 

infested with flesh eating rats, and soon the gore is spilling everywhere.
