WWYD- New ebike won't fit in bike locker

I decided to get an ebike to ride to and from work on the days I need to be in the office since it's only 4 miles away and I'm trying to find ways to get more incidental activity. I was concerned it wouldn't fit in the outdoor bike lockers I got so rode there today to practice and check it out and the ebike won't fit inside 😩

WWYD? I work at a government building with security inside. We cannot bring bikes inside (though I'm going to double check on this). There are a lot of non-employees meandering about the main parking lot and front area where there are racks I could lock my bike up to.

Here are the options I'm thinking I have:

1. Lock to rack outside building, remove battery and bring inside every time. I have a good kryptonite u lock with chain but I know no locks are theft proof.
2. Return the bike and try to find something smaller? The bike I got has fat tires - I'm a larger person and plus I wanted to be able to go on trails with my kids. Overall preference.
3. Remove front tire every time so it fits in the locker. They aren't quick release.
4. Jump ship and just pay for parking and drive ☹️

Maybe there are others I'm not thinking of. TIA.
