my understanding is that theives have trouble keep the chain steady to cut it. Everything is super strong, high quality, heavy, I feel like it will really slow down thieves. I use it to lock my bike out on the street in front of my apartment when I get home, I carry a smaller disc lock with me for when I'm out and about. I believe with time and determination someone can cut or break any lock but I think this is about the best deterrent you can get. Good luck. Ride safe.

One of the top rated bicycle locks out there. Impervious to hand held bolt cutters,and fairly resistant to portable grinders. It's weight is the only drawback, only suitable for ebikes or to leave locked up at a regular destination.

This lock is very strong and likely to deter thieves. However, that strength comes with a cost, as the lock and chain combo is very heavy and awkward to carry. I only recommend this lock if you can keep its a bike rack and don't have to haul it back an forth.
