• 16mm hardened steel intimidates opportunists before a tool is drawn
• Includes a frame-mount bracket and covered disc-style keyway with anti-theft protection registration

• Heavy for its compact locking area, at roughly four pounds
• Like nearly all consumer locks, it yields to a determined angle-grinder attack

Abus Bordo Granit XPlus 6500 Folding Lock

Buy it

The rare folding lock with genuine high-security credentials, folding flat to a pocketable block while wrapping awkward objects a U-lock cannot.

• One of the very few folding locks to earn a top independent security rating, with 5.5mm hardened steel bars and a pick-resistant disc cylinder
• Folds into a compact block and reaches around fat posts, racks, and large frames that defeat a rigid U-lock
• Ships with a solid frame-mount holster for rattle-free carry

• Heavy for a folding lock and priced at the top of the category
• The many rivet joints are inherently more attack points than a single U-lock shackle
