Default Re: what are these two nubs on the seat rube

They were there to mount a water bottle or an air pump. Remove the Allen head bolts and either mount the engine over the threaded insert or grind off the protruding portion.
Keep in mind that you want as much metal to metal contact as you can get in the mount where it attaches to the bike frame.
