It’s one of the better maintained of the fully-separated bike lanes too. Bikemore has a GIS map with labels for all the bike lanes in the city - as you can see, the corridor you’d be biking has a bunch of separated or buffered bike lanes, arguably the best in the city.

Baltimore had something like Bluebike for a bit but the vendor had a huge maintenance backlog and the city just cancelled it. Now we have a hodgepodge of dockless bikes and scooters; I believe it’s Spin, Bird, and Superpedestrian at the moment. (DC’s Capital Bikeshare is a great system, btw - some healthcare plans and employers in DC will subsidize membership, along with transit like Metro and MARC.)

You can bring bikes on the train.
