Lock Testing

Certification Testing 

All 1.25 inch wide TiGr® Locks (including the TiGr® mini) meet/exceed bicycle security standards and have been certified for bicycle security.

Independent European laboratory technicians have tested TiGr® Locks using real world modes of  attack including  hammers, bolt cutters, pry bars, bottle jacks, saws and found the titanium locks suitable for bicycle security.

In-House Testing

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 the majority of cases, the thieves attempts leave marks on the locks but do not break the lock.

The loss rate in theft attempts showing signs of bolt cutter use is low, but it’s not zero. There are bolt cutters in the world that can break the titanium shackle.

TiGr® locks are appropriate for longer stops in low/moderate risk situations and shorter stops where risk is higher, but not for long stops where risk is very high.

Please Remember

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)
