Some possibilities:

1. Take the wheels off, and hide it in your closet, or in a bike bag against a wall. Out of sight, out of the way, out of mind.
2. Buy a locking motorcycle cover, lock the bike in the approved storage room and lock the bike cover on it.
3. If you own a car on campus, store the bike in the car, covered to hide it.
4. Get an apartment next year.
5. Buy a folder.
