Pentagon D Lock 240 Extreme | Sold Secure Diamond

This is the serious one. The D-lock 240 Extreme carries a Sold Secure Diamond rating — the highest there is, and rare on a lock at this size. If you're leaving an e-bike or cargo bike locked up in the city, this is what you want on it.

The pentagon-shaped 14.1mm crossbar is stronger than the round bar used on conventional D locks, and there are extra steel plates reinforcing the vulnerable parts of the body. A double deadbolt mechanism kills twist attacks, and the extra-wide crossbar clearance means you can actually get it around thicker frames, fat tyres and awkward bike racks.
