Is there a way to ev train before the next region?

(what I mean is to have my scyther ev trained why still being under level 16)

I just finished my second region and was planning to go to unova, and I was wondering if I could ev train one of my mons before moving there. I don't like to have to ev train in the early game, as there aren't that many horde locations, and pokemon moves are pretty weak, so I want to ev train ahead of time.

Use a low exp. horde and divide the exp. between as many pokemon as you can. That should do it.
