You could do a one way car/van rental from National Airport and drop it off somewhere close to your Pittsburgh hotel. Something like a mini-van but a car could work if it has a huge trunk for two bikes with the front wheels removed.
There’s also Amtrak, DC to Pittsburgh (Capitol Limited line). Try to reserve a bicycle ticket (roll-on, roll-off) or if those are unavailable, just buy a bike box but know you need to twist your handle bars and remove your pedals (have those tools on your person). The bicycle tickets are trickier to reserve (only so many) but Amtrak with a bike box isn’t the worst thing, I’ve done it a few times.
Let us know what you ended up going with and good luck.
