My son and I might be game for Ruiodoso/ Cloudcroft area but dont know anything about the offroading there. With barely legal bikes, Im not real keen on much onroad stuff.
Looks like some TWT folks are already there:

IIRC, if you don't mind hauling bikes to trailheads, there is lots of pure offroad stuff.
