Not everyone knows this but you can ride your bike and check it in on many of the long distance trains. They check in the bicycle on bike racks at the front of the train.
Not every train or stop has this, but the major ones along the west coast do (California Zephyr, Coast Starlight). When I was going to Reno a lot (long story) I used to take my bike on BART, cycle from West Oakland to Emeryville, check it in on the train, get out in Reno and cycle away.
Of course you’ve got to figure out an easy luggage situation (something easily detached) but I only ever had a small bag with me so it was fine.
I just saw a bunch of people checking their bikes. They’re taking the train to Santa Barbara with their bikes. It’s a $20 one way add-on
