I googled an image of those bikes. They strongly resemble a standard bicycle. I cannot quote Amtrak rules but it appears you will be fine. Obviously you will have to make a reservation AND purchased the bike pass to get on with your bike. Since the conductor generally assists passengers in loading you can make the conductor’s decision easier by having your CASH TIP ready. Remember the train ALWAYS runs on a tight schedule and that conductor has a job to do. That very busy conductor is taking a minute or two to help you. Help him help you $$$.
Also, since carrying the bike up the steps and around the corner is kind of awkward, make sure you are ready to load IMMEDIATELY with ZERO delays removing panniers etc. This means if you have panniers or racks ETC they are already removed and waiting for you to carry on a second trip up into the car. This is my two cents after doing this trip once, but three years in this and the two big Katy groups on Facebook.
