If you're tired of fumbling for keys every time you need to lock up your bike, this Etronic combination chain lock is about to make your life so much easier. The 5-digit resettable combination means no more lost keys or struggling with sticky locks - you just set your own easy-to-remember code and you're good to go. The 4-foot long chain gives you plenty of length to secure your bike to poles, racks, or fences, and the 1/4-inch thick hardened steel links are seriously tough against cutting tools. The square-link design makes it even harder for bolt cutters to get through, and the nylon sleeve protects your bike's finish from scratches. But it's not just for bikes - use it for motorcycles, ATVs, grills, ladders, tools, generators, or anything else you need to keep secure. At 1.95 pounds, it's heavy enough to deter thieves but still manageable to carry. The anti-pick mechanism gives you peace of mind, and being completely keyless means one less thing to lose or forget. Whether you're locking up on campus, at work, or around town, this chain lock provides solid security without the key hassle.
