In Stiftung Warentest's bicycle lock test, 81 models compete. Almost a third failed. Fortunately, there are also good locks for little money.

The Trelock is very secure when it comes to theft protection. The slim accessories and weight cost a few points. All in all, a convincing price/performance winner.
