Lock Testing

Insurance Certification Testing

You can recognize a safe, high-quality lock by its ART seal of approval.

ART-approved locks have been extensively tested by an independent laboratory for durability, weather resistance, environmental resistance, and attack resistance.  

To receive ART approval, they must meet certain requirements. The testing lab subjects locks to over 20 tests, including a freezing test, dust test, corrosion test, endurance test, cutting test, tensile strength test and attack test.

The ART quality mark uses a star rating system.

ART 2 lock   – for bicycles

An ART 2 lock provides quality protection against bike theft. Bicycle insurance policies require an ART lock with a minimum of two stars.

 

TIGR Lock High Carbon Steel Locks were certified for bicycle security by the ART^® Foundation in 2019.

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 were found to hold up to attack testing as well as, or better than, cable locks, most folding-style bicycle locks, many chain locks and typical u-locks with less than 12mm diameter shackles.

TIGR Locks are not recommended for long stops in high-risk situations or outside overnight in moderate/high-risk situations.

 

TIGR Lock high carbon steel shackles were introduced in 2020. Both in-house and independent third-party testing shows that high carbon steel shackles are hard to cut with a wider range of bolt cutters and hacksaws. 

Please Remember

Locks reduce the risk of theft but can not eliminate the risk.

Some things to consider:

• Know where the high-risk areas are and avoid parking your bike there.

• Lock to a secure fixture.

• Keep the lock low to the ground to make an attack more difficult.

• Lock the frame and both wheels if possible, and take easily removed accessories with you.

• Avoid leaving your bike locked in one place for long periods on a regular basis.

• 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 - as riding bikes is fun and good for you!
