Great for use as a trailer wheel lock
I can easily slide the open end of the U around the springs on my trailer and the two prong ends of the U through two holes in the rim of my trailer tire wheel, and then I attach the bar lock. Someone can then move my trailer a very short distance before the wheel, U Lock, and spring bind up against each other. I feel that this is much more secure than just having just a lock on the latch at the ball. After using it a few times, I find I can install it from a squatting position without having to crawl under the trailer. I have another U lock which didn't work because the U was too short. This one has such a long U that it works well. I have been using it for approximately one year and it is showing no signs of weathering. Great product.

Excellent Medium Security Bike Long U-Lock
This is a very good medium security long u-lock, IMHO. The weight is moderate rather than very heavy like the highest security u locks, one of which I returned because of its heavy weight. That's the trade off: if you need the highest level of security you have to carry a very heavy lock. I really like this lock's long and wide U for locking my bike's front wheel and bike frame to a bike rack. I use a smaller u-lock to lock my rear wheel to the bike frame. There's no frame attachment with this lock, so you need a way to haul it around. Years On: Now 2026 and I've used this lock frequently for years. It's still working just fine. Recommended. Upgraded to 5 stars.

Great for the money.
For $20 these are great, and this is my second one. I love the extended U design, it makes locking much easier. Aftermaybe six moths months the locking mechanism got gummy/jammy, which I think is because the long "U" eventually was not quite straight anymore, plus some rain corrosion that I could see from leaving it out for a few months at one point. Possibly could have been fixed with WD40 a cleaner, but then I lost the lock. Anyway, I am buying another one now, so I rate it "good+", despite having a couple of imperfections.

Great sturdy U-Lock!
This U-Lock is large and versatile. I use it for my bike, where it often comes in contact with rain. I used to have a different U-Lock and whenever it rains, the inside of the locking mechanism gets rusty, causing me to have difficulty inserting the key. However, this lock does not have that problem. It deals with the rain really well. I even bought the same exact one for my girlfriend.

So far, so good!
I've used this lock for about three weeks now. So far, it's worked fine. It's large enough to capture the front wheel and a frame bar while it embraces the bike stand. Chicago has hefty bike stands with stout material for locking the bike to. So, I need the extra large size of this lock. In fact, sometimes I wish it were another half-inch wider. It's certainly long enough. I don't leave my bike outside. So, I don't know how this lock might stand up to constant exposure to more challenging conditions than it encounters while my bike is stored in the basement. When I registered my keys, I discovered that this lock is made by that other lock company whose name makes you think of Superman.

I Trust It With My Bike
It's a Good Lock for Keeping Your Bike Safe. It' made of Heavy Metal,Steel Maybe;(i'm not an expert) like most U-locks use to be. I've noticed a lot of the newer brands out there seem to have plastic casing more than metal, so I've been looking around for good U-locks (cables ARE a waste of money for keeping your bike, yours) It's 11 inches long like the advertising says, so think about whether you would want to drag it around w/you, unless you bike w/a friend. That is the plus in this lock because it can lock 2 bikes easily to a post, bike rack, someplace w/a heavy anchor to discourage possible thieves.(IMO)I use it to lock 2 bikes on a 2nd floor balcony that faces a semi busy street, neighbor, etc. I've had a bicycle stolen off my 2nd floor once when I first moved into this neighborhood. (it wasn't locked; didn't think it was really necessary) Now I lock the bikes up out there, using the metal railing's thickest bar as the base. Hope my experience helps you choose a Good Lock. I Love It :)

Will definitely buy this type of lock in the future. It's perfect.
So much sturdier than a regular padlock. There's an added "twist" maneuver that must occur before lock can be secured with key. I love it.

Great buy!
Does the trick, a simple, long, U-lock that will fit most standard bike racks. It is not too skinny either. It keeps the same width as most U-locks. Great buy!

U-lock for bicycle
Item exactly as described. Fast and efficient delivery. Made of quality material. I would definitely buy from this seller again.

Buyer Beware!
Chose this lock because of brand reputation, however was very disappointed. This is simply a deterrent. The cylinder is not fully covered from all sides and the back is hollow. It is covered by only the sleeve of the lock (blue section). Cutting the sleeve will expose the shackle. Quality is just poor.

Bon rapport qualité-prix
Pas le plus solide bien sûr, mais pour le prix, il est très satisfaisant: imbattable je dirais. Me semble robuste. Ne pèse qu'un kg. Longueur du U idéale pour relier le cadre, une roue et le point d'attache. En séparant le U de la tige de serrure, il se transporte bien dans un sac de dimension moyenne sur le porte-bagages arrière. Mieux qu'un dispositif incertain de fixation (avec vibrations) avec velcro sur le cadre (il n'y en a pas de fourni de toute façon avec ce cadenas). Se verrouille et déverrouille aisément avec la clé (mécanisme fluide). Je recommande ++ (pour un vélo pas trop cher bien sûr et des arrêts courts en zone avec circulation de piétons!).
