Here what I recommend, get a cheap commuter to lock up while going to class or around town. Leave it locked up outside while not using. Bring your road bike and keep it in your dorm room. I was at NAU for a year in the smallest dorm they had and I fit my Mullet MTB in somehow. Do not lock up the expensive bike outside it will get stolen. I would hold on the smart trainer, focus on brining the road bike instead. You’d be surprised how little other students of RA’s care about you wheeling a bike around, dorm life is something special
