ONGUARDBrute STD 8001 Bike U Lock - Sold Secure Gold

The best D lock in the market, unbeatable quality-price relation. I gave it 4stars because is bit heavy.

A brute, in a good way. Heavy, as expected, so tend to leave it in the bike cage at work.

Good lock.

Heavy solid lock, comes with five keys and mount bracket, gold rating and one of the best D locks you can buy.

I bought this lock because it has some good feedback on Youtube, including its alleged resistance to tool-assisted breaking/cutting.Don't be under any illusion that this is a safe lock if you leave your bicycle unattended for longer than a few minutes! It will not withstand thieves that are armed with a grinder/cutting tool.I had my new e-bike locked to a safe metal bar on the busy and CCTV surveilled ambulance ramp at my workplace in London, where my bike was stolen during daylight hours. The lock, cleanly cut in half, is the only thing I still have left. CCTV showed the theft and it took the thieves less than two minutes to arrive, break the lock and disappear with my bike!I come to the conclusion that there probably is NO lock in existence that brazen thieves can not break into with ease! Probably the only way to secure your more valuable bicycle is by installing a hidden tracking device. Your bike will still be stolen if a thief puts his mind to it, but at least you might have a chance to retrieve it afterwards.

By far he best bike lock I have purchased these were advised my my bike insurer. Keys have unique pin

Solid lock. very good price for gold standard sold secure.

Great item
