Abus and Decathlon Lead in Bicycle Lock Security Tests

Recent evaluations by Stiftung Warentest and IMTEST highlight top-performing bike locks for theft resistance and durability.

Stiftung Warentest tested 19 bicycle locks across various types, with only four models receiving 'good' or 'very good' ratings.
Abus Granit Extreme 2500 emerged as the most secure lock, requiring six cutting discs to breach, but costs approximately 300 euros.
The Decathlon Kettenschloss 920 Art3, priced at 60 euros, was recognized as the best value among chain locks, despite its 3.2 kg weight.
The IMTEST evaluation praised the Abus CityChain 1010/110 for its robust build and high resistance to power tools, though its locking mechanism occasionally sticks.
Proper maintenance, such as using specialized lock spray, is recommended to extend the lifespan and functionality of these high-end locks.
