TiGr® Locks were certified for bicycle security by the ART® Foundation of the Netherlands in 2012.
Independent Test Video
This video shows an independent bike advocacy organization in New York City (BikeNYC.org) attempting to break a 1.25″ wide TiGr® Lock with a variety of bolt cutters.
Engineers run destructive tests using the same tools (hammers, saws, levers, shears, bolt cutters, power tools…) bike thieves are known to use.
TiGr® Locks hold up to attack testing as well as, or better than, popular u-locks, chain and folding-style bicycle locks.

About bolt cutters
The videos on this page show the bolt cutters used when designing/testing the titanium shackle in 2011.
Independent laboratory testing done in 2012 confirmed that the 1.25 inch wide titanium shackle meets/exceeds bolt cutter test criteria for bicycle security.
Tens of thousands of titanium TiGr® locks are in use every day all over the world, some since 2011. There have been reports of actual bolt cutter attacks. In most cases apparent bolt cutter theft attempts leave marks on the locks, but the would-be-thief is unable to break the lock and the bike is saved. However, all locks can be broken.
TiGr® locks are appropriate for longer stops in low/moderate risk situations, for shorter stops where risk is higher, and not appropriate for long stops where risk is very high.
All locks reduce the risk of theft, but no lock can eliminate the risk.
Some things to consider:
- Know where the high risk areas are and avoid them
- Lock to a secure fixture.
- Keep the lock low to the ground to make an attack more difficult.
- Lock frame and both wheels if possible and take easily removed accessories with you.
- Avoid leaving your bike locked in one place for long periods of time and avoid using the same location every day.
- Lock the bike in plain sight, and with other bikes when possible.
- Register your bike with your local police and/or a bike registration website like https://bikeindex.org/.
- Ride your bike (it’s fun)
