SAF Lock. The First Angle Grinder Resistant Bike Lock.
Built to protect against the strongest attacks. The SAF Lock is a new tier in bike security.Overview
The Altor SAF Lock is the world’s first angle grinder resistant 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 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 comes with four matching keys, so you can share with a friend and have a backup in case one is lost.
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. Read and watch their complete review here.
The SAF Tech Shell prevents any meaningful damage from occurring while causing damage to the angle grinder disc. The SAF Tech Shell is designed to withstand attacks from angle grinders with cutting discs up to 5 inches in diameter.
All portable angle grinders tested against the SAF Lock eventually failed due to one or more of of the following:
- Battery died.
- Angle grinder overheated.
- Angle grinder disc broke.
No portable angle grinder has been able to cut through the SAF Lock.
We designed the SAF Lock to be as strong as possible, not as portable as possible. Keep the lock locked to your rack at home or at your office and have a second, smaller, lock for when you go to get coffee. The SAF lock weighs about 13.7 lbs or 6.25 kg which is lighter than some chains, but heavier than you’ll probably want to carry.
We stand by our lock and we’ve made over 45 minutes of testing videos available. Watch the SAF Lock go up against three of the top rated angle grinders in the video below.
