Tired of carrying around keys for your bike lock? Check out this CoilKASE Combo MAX - it's a 180cm (that's about 6 feet) coiling cable lock with a sweet 4-digit combination instead of keys! The advanced steel ball combo gear system makes it seriously tough for thieves to pick or pull apart. You get to set your own 4-digit code with 10,000 possible combinations - way better than worrying about losing keys everywhere you go. The cable itself is 12mm thick and heavy duty, plus it has this cool self-coiling design that makes storage super easy when you're not using it. There's a tough protective vinyl cover over the cable to prevent scratches on your bike frame, and the locking mechanism has this integrated protective coating that makes it more durable and reliable. Perfect for securing your bike around town, at school, or while running errands. The coiling feature means it doesn't take up much space in your backpack when you're riding. Setup is quick - just choose your code and you're ready to roll. Much more convenient than key locks, and way more secure than those cheap cable locks that snap easily!
