Review on Allnice Bike Lock Cable - Mini Cycling Combination Lock for Bicycles - Portable Anti-Theft Resettable 4 Digit Lock - Ideal for Travel, Luggage, Helmet Security by David Bowens

I wanted a small, light lock to carry on my bike. I didn't need a solid lock to leave my bike around town for the day, just something simple to keep honest folks honest in my small town. I was surprised that this lock is the perfect size and weight. I am attaching photos of how easy it fits on my bike. It has an impressive four-digit locking mechanism, which I believe has 10,000 possible combinations. It also has a vinyl coated spiral wire. Although the barrel is a little heavy and the wire is a little lighter, I think it's good enough for my current needs. It will stretch about 4 feet, maybe an inch or two more. Its length is just enough to attach my frame and rear wheel around the shield. I'm a happy customer.
