Lock your bike quickly with this clever folding lock! The Keeper 510 uses 3mm hardened steel bars that pivot into a compact rectangle. It's 100cm long when unfolded—enough to secure your frame and wheels to a rack or pole. Weighs just 1.9 lbs, so it's easy to carry. Includes a mounting bracket that attaches to your bike frame for on-the-go access. The rubber coating protects your paint. Comes with two keys. Register it for Kryptonite's Anti-Theft Protection Offer and Key Safe program (free key replacement if you lose yours). Great for quick stops, coffee runs, or medium-risk areas. Not the heaviest-duty lock out there, but way better than a cable. Fits in a backpack or pannier. A solid, convenient choice for commuters, casual riders, or e-scooter users. Peace of mind without the bulk!
