Let me start by saying this lock is a BEAST. After having my bike stolen twice, I decided to invest in the ABUS Granit Super Extreme, and wow—this thing feels like it could survive an apocalypse. The 20mm square shackle is so thick it looks like it belongs on a bank vault, not a bicycle.

The real test came when I watched those brutal angle grinder torture tests (yes, ABUS actually shows them—unlike some competitors *cough* Kryptonite). Seeing it take 13 minutes and multiple discs to cut through ONE side? That’s the kind of performance that lets me sip coffee at the café without constantly glancing at my e-bike.

But it’s not all sunshine: At 2.4kg, you’ll feel this monster in your backpack. Mounting requires some finesse too—the alignment can be picky. Pro tip: Push down while locking to avoid frustration. And ABUS, if you’re listening—please include a soft shackle cover next time! I had to DIY mine with tape to prevent frame scratches.

For heavy-duty security (especially for €200+ e-bikes), this is hands-down my top pick. Just don’t expect to lock it around thick trees—that massive shackle has limits. Five stars for protection, minus half for user-friendliness.
