Keep your bike secure with this Lumintrail combination cable lock that offers convenience and solid protection! The 4-foot long, 12mm diameter military-grade braided steel cable is tough, flexible, and provides strong cut resistance that deters thieves. The vinyl coating not only adds durability but also prevents scratching your bike's finish. The 4-digit combination lock is completely keyless - no more worrying about lost or stolen keys! You can reset the combination as many times as you like to create a personalized code that's easy for you to remember but hard for others to guess. The lock features a secure deadbolt mechanism that's pick and pry resistant for added security. It comes with a convenient mounting bracket that easily attaches to your bike frame (fits 1-inch diameter seat posts or tubing) so you always have your lock with you when you need it. Weighing just 13.2 ounces for the lock alone, it's lightweight enough for regular use but sturdy enough to provide real protection. Versatile enough to secure bikes, scooters, skateboards, motorcycles, lawnmowers, grills, patio furniture, tool boxes, ladders, and much more. The self-coiling design makes storage and transport super easy!
