You have to put some thought into riding in inclement weather, as well as road salt.
I assume Spring is on its way now, but by this fall, you might consider a vintage MTB for winter commuting, including getting studded tires.
Or, walk, jog, or take the bus for that 2.7 miles if riding on the road isn't safe.
It appears as if fenders are being sold as an accessory, as well as racks, and lights. Also available elsewhere.
Oh, the company also is selling flat-free airless tires. I have them on one bike (Tannus brand, a bit narrower than they're using). I have mixed opinions about them, but they'd be great for a commute where you don't want to mess around with flats, or being forced to walk.
However, don't plan on easily swapping airless tires and studded tires unless you get spare wheels (also a reason for a snow bike beater bike).
