Tired of fumbling for keys every time you need to lock up your bike? This combination U-lock lets you set your own 4-digit code instead - no keys to lose or forget! With 10,000 possible combinations, it's way more secure than those cheap cable locks that thieves can snip through in seconds.
The shackle is seriously tough - 16mm of hardened zinc alloy that resists bolt cutters, knives, and leverage attacks. It's got a PVC coating too, so it won't scratch up your bike's finish. What's really cool is the adjustable shackle that extends from 160mm to 270mm, so it fits around bike frames, fences, glass doors, gates... pretty much anything you need to secure.
Setting your combination is easy - there's a little switch inside that you flip with the included screwdriver, set your numbers, then flip it back. Just don't forget your code because there's no backup key! The lock itself is about 6.9 inches with a 13.4 inch shackle, giving you plenty of room to secure your bike frame and wheel to a rack. Works great for e-bikes, scooters, motorcycles, lawn equipment, sheds - anything you want to keep safe outdoors. Way more convenient than key locks and definitely more secure than those flimsy chain locks most people use!
