BRINKS - 3 7/8” Mini U-Bar Lock - Weather Resistant and Pick Resistant Bike Lock, Blue

These are really good quality! Thick and works really well!

This is a great lock! I purchased it along with a thick cable to lock my CT70 clone to my wife's Honda Navi when we would go on rides and want to stop. This thing is bulky and tough. I figured it would take someone a while to get through this security lock. The locking mechanism is easy to use. Happy with my purchase, as you will be too!

Yes yes yes awesome locks

Surprisingly for me (I never heard about the Brinks brand), these locks are manufactured by Hampton products, a California-based company. I did not check where the lock is actually made, and now the packaging is already thrown away. It is a rather small lock (fits into the palm of my hand) and is relatively light (let's say, lighter than I expected - which made me wonder what metal it is made of, and how much metal is under the blue silicone coating). The size is adequate to use it with a bicycle security cable or a chain. Some people wrote in their reviews that this lock is hard to lock and unlock, I got two of these locks and found just the opposite to be true - it locks and unlocks very smoothly with no effort. Regarding security, I am not an expert in assessing lock security, but I can tell that it has a tubular lock (comes with two keys). This is a type of key which is used in all low end bicycle locks and, to my non-professional understanding, is considered a fairly low security type of lock which is easier to pick than more complex types of locks. Of course, there is no lock which cannot be opened or broken by a skilled thief; locks in this price range must be on the easy side for a pro to open, but at least it is a theft deterrent. It is labelled "water resistant", but not waterproof, if that matters. So, probably, it is not designed for a full time outdoor use if they lock is exposed to rain on a regular basis.

A friend had their bicycle stolen. That made me look for the strongest lock a cable for my bike. After narrowing down my choices. I decided on Brinks for both.

I needed this for an antique boat chain which is decorative in my yard. It sits in the Florida sun 24/7 and it looks as new as the day I bought it. Whatever your use for it is know it will stand the test of Florida weather. lol

Unfortunately, for me, this doesn’t work because I have multiple cables and there’s not enough room to lock this in place but durability I would give it five stars.

Lock looks great and really sturdy but impossible to easily unlock. Not worth the effort or aggravation.
