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 them suitable for bicycle security.

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.

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 that German Video

In 2013 a German company published a video on YouTube showing a young woman breaking the narrower/lighter (0.75 inch wide) version of the TiGr® bow with large bolt cutters. That video does not show the 1.25 inch wide TiGr® locks which were ART® certified at the time.

1.25 inch wide TiGr® locks are better suited for higher risk situations. The narrower, 0.75 inch wide, TiGr® locks are well suited for shorter stops and more moderate risk situations.

Please Remember

All locks reduce the risk of theft, but no lock can completely 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)
