We produce a new general family of flat tori in R4, the first one since Bianchi's classical works in the 19th century. To construct these flat tori, obtained via small perturbation of certain Hopf tori in S3, we first present a global description of all isometric immersions of R2 into R4 with flat normal bundle.
