Altor SAF Bike U-Lock – Strongest Bike Lock

strongest bike lock

Altor really has created the strongest bike lock currently available with the SAF. A bit different to what they have normally built, with lightweight locks. This one really does take physical security to the extreme. 

“Strong As F**K – Strongest bike U-lock”

Notes on the build

If you are looking for a bike u-lock to carry around with you then THIS IS NOT WHAT YOU ARE LOOKING FOR. 

Weighing in at 13.7 lbs or 6.25 kg this bike lock is much too heavy to be a portable option.

It is also very expensive, being more than twice the price of Kryptonite New York Lock Fahgettaboutit Mini, one of the other best bike U-locks currently on the market.

The lock is a disc-detainer similar to the Abloy profile cylinder that requires unique tools to be able to pick.

Who is it for?

So this is for someone that has a very expensive bike that must stay in a high theft risk area. Keeping an expensive road bike in a public place for a long period of time or securing an electric bike in the public area of an apartment building. 

Or for a high-security lock for you to leave your bike in a dangerous public area at work.

  • 14mm hardened steel core shackle inside 78mm aluminum shell
