Dutch is right on the border area between ē and ei. Most Dutch words have ē, but it seems that certain words, in particular those with umlaut, have ei instead. The words with ei become more frequent as you head east and south, and the form reger is also attested in Middle Dutch. With there is another explanation though: the -g- that disappeared may have raised the vowel before it. I think there are other words that have that (including native Romance ones).
