The ABUS Iven Chain is a beast of a bike lock that doesn’t scratch your paint. It’s an 8mm thick square-link chain made from specially hardened steel, which is incredibly tough to cut. What’s cool is the whole chain is wrapped in a flexible, weather-resistant synthetic fabric coating (they call it IvyTex) that protects your bike’s frame from getting scuffed up. It’s 110 cm long, giving you plenty of length to lock your bike (or e-bike) to a solid post or rack. It comes with two keys and has an ABUS security rating of 10 (their high level). Yes, it’s heavy at about 2.2 kg, but that’s the trade-off for serious security. If you want a chain lock that deters thieves AND takes care of your bike’s finish, this is a top choice.
