Stiftung Warentest tests two textile-based flexible bike locks: Tex-Lock and Litelok. The Tex-Lock, though lightweight and flexible, failed the security test and could be cut quickly with standard tools. The Litelok, with a plastic-coated steel core, resisted attacks comparably to traditional locks and was lighter than most U-locks. The review concludes that while textile locks address weight concerns, only the Litelok provides adequate theft protection. The article advises cyclists to prioritize security over convenience and warns that no lock is completely theft-proof, but some offer significantly better protection than others[5].
