Nothing out there can stop a cordless angle grinder nowadays. I got my kid a 10mm hardened steel chain along with a moto lock for his bike at college. Its only for overnight lockup near the dorm as the chain alone must weigh 12 pounds.
The problem with fat bikes is that there aren't a lot of choices for locking the bike. A normal size u-lock that will go through the rear spokes and the seat tube just won't fit a fat bike. Hence, the chain and not a dinky one either. 12mm is a good balance between weight and thickness.
The
Krytonite Evolution 4LS U-lock has longer arms but can only be used to lock the front wheel to the downtube.
