SAF Lock

The Altor SAF Lock is the world's first angle grinder proof bicycle lock. Angle grinders have become the new norm in bike theft, yet every bike lock on the market is only designed to protect against hand tools. At Altor, we've been making and selling bike locks for years and have seen first-hand how destructive angle grinders can be. It became our mission to do the impossible.

We created the best, most secure bike lock in the world. Made from a 14mm hardened steel shackle, wrapped in our patented aluminum shell, and attached on both sides to a double-locking cross bar inside a hardened steel case, the SAF Lock will defend your bike against even the most determined attack.

 The SAF Lock Features:

  • A 14mm hardened steel shackle
  • Our patented aluminum protective shackle
  • 80mm shackle diameter
  • Double Locking Cross Bar
  • High security disc detainer lock mechanism
  • Soft Outer Coating to protect your bike
  • 6.2 kgs total weight
  • 200 x 280 mm outer dimension

Actor locks

The only down fall is that it is hard to lock your bike up on the rack, because it is so big and not enough length to easily look your bike and go, it takes some time to adgust and get it to close, I almost wanted to see if I could send it back, but on the good note it is a super secured lock, and like it is advertised it can save your bike, becouse this is a super massive lock, and if a theft try to brake this lock, they would have to be a pro, and have a lot of time, and the noise it will make should make anyone aware of something is going on, and mostly Likely they will no bother your bike, even the guys that have equipment, and a haul truck would probably look for another bike once this lock is on, it to much work to get this lock off.

This lock is a beast, I feel safe leaving my bike locked up outside and I love showing my friends my lock. The look on all their faces is priceless.

The only outdoor lock worth using

I normally use my Fahgeddaboutit Lock, the Abus Granit Xplus, AND Pitlocks on my wheels; but I consider those adequate only in low-risk situations. I know that if an experienced thief has more than a few minutes to work on these, they really don't pose any obstacle; accordingly, til now I have never left my bike unattended for more than an hour outside, even with all my locks. However, for the last month it has been unfortunately necessary for me to leave my bike locked outside overnight, a horrifying prospect for me. I was reluctant to spend the money on the SAF lock; but I forced myself to answer this question honestly: if tomorrow my bike was stolen, would I regret not buying the SAF lock? The answer was yes, of course. The replacement costs would not only include my bike, but also all the locks I had used to secure it. Another obvious downside is the weight: I can barely lift the thing, I almost need two hands to lift the shackle alone. Also, the locking configurations are limited: there's only one way I can lock the frame to the rack, because it's too thick to work any other way. But The Altor SAF lock is the only security measure that exists on the planet that offers my bike any theft protection for more than 2 minutes, and I am so grateful for that. Thank you Altor.

Bike thieves using angle grinders in broad daylight is the new normal. Don't let it happen to you.

The SAF Lock is perfect for...

Overnight Locking

The SAF Lock is the ideal lock for keeping your bike safe overnight. It is specially designed to thwart any attempts to cut it. This isn't your everyday carry lock. This is the world's strongest lock.

E-Bikes

Your E-bike is a valuable target for would-be thieves, and at 13.2 lbs (6.0 kg) the SAF Lock weighs less than many chain locks you may already be considering using. The only, and most important, difference is that those chains can be cut in under 45 seconds while the SAF Lock can't.

Frustrated Cyclists

Has your bike been stolen? After years of designing and selling locks, we know that angle grinders defeat even the best of locks. Since the advent of the affordable portable angle grinder, thieves have increasingly traded up their bolt cutters for angle grinders. The SAF Lock is the first and only lock designed to combat this.

Bicycling Magazine
Cut Test

Bicycling Magazine took our lock to task and produced a comprehensive testing video. While it takes seconds to get through normal bicycle locks, it took Bicycling Magazine over an hour and multiple angle grinders, blades and batteries to get through our lock.

Angle Grinder Resistant

The combination of material and geometry of the SAF Tech shell quickly wears through angle grinder discs and batteries.

Pick Resistance

Designed from the ground up, the SAF Lock uses an eight disc disc-detainer lock mechanism with false gates and a unique key profile that makes picking as difficult as possible.

Resists Traditional Attacks

While the SAF Tech protects from angle grinders, The SAF Lock's through-hardened steel core shackle and anti-rotation locking bars stand up to the toughest of hand tools.

LockPickingLawyer Pick Test

The LockPickingLawyer says "the chances of this being picked on the streets are essentially zero". Watch as he picks the SAF Lock with a pick he custom made himself because there are no picks commercially available for the SAF Lock.

Double Up

The Double SAF Lock comes with eight matching keys, so you can share with a friend and have a backup in case one is lost. Leave one at work and one at home, or share one with a friend
