Review on Bike U Lock with Cable - Via Velo Heavy Duty Bicycle U-Lock, 14mm Thick Shackle and 10mm x 1.8m Steel Cable with Mounting Bracket - Ideal for Road, Mountain, Electric, and Folding Bikes by Don Leblanc

There isn't a bike lock in the world that can't be picked in under a minute with the right tools. All you can really hope for is to make your bike more difficult to access than the one next to you. Using this lock properly with a U-bolt around the post, through the frame and rear wheel, and a cable through the front wheel will definitely make a would-be thief stop and look for an easier grip. The U-bolt is quite strong and the locking mechanism engages either end of the bolt. The cable is large enough to cut, you will need larger wire cutters.
