Best way to stop the first mongol units?

hi, i am playing (only 1vs1) with holy roman empire. im only losing to mongols.

i have a build order to start my second urban center at 5.30 or so, so pretty much in all my matches i am free to do this except vs mongols, since they can send you 2 horses and another 2 horses more in the first minutes.

i am trying to figure out what is the best way to adapt my build order vs mongols, i can’t build a early barrack + lancers because that would delay my strategy too much.

are outposts my single option vs this?
