ICOCOPROAnti Theft Heavy Duty Bicycle U Lock with 3 Keys, 18.76mm, Black, 5.32 in Width Inside Dimension

I'm a contractor and have had several smaller ladders stolen off the ladder rack on my truck. I bought these to lock the ladders and it's working great. They're really thick metal, so would take some real work to cut through, especially while balancing on the rear bumper of a truck. The U-shape construction is wide enough to wrap around the thickness of the 1" aluminum rack and the ladder tread. I especially like the little button that covers the key entry so as to prevent rust and corrosion of the lock. So far, so good!

Fits well with scooters. Very durable and easy to unlock and lock

After looking and reading reviews, watching YouTube videos, this lock just felt right for my new e-bike. I saw some concerns about weight, but the weight doesn’t feel so different than most U locks. I feel weighty and thicker is more secure. Love that it comes with 3 keys, which all work perfectly. Happy with my purchase and recommend product.

This lock cannot be cut in two in easily or quickly.

Loving this bike lock. I really like the rubber coating over it. Works well. The only issue is that it’s not super deep of a u shape so its hard to hook up more than one bike.

I use 2 locks. The insured kryptonite one and this one for added safety. Honestly, it feels sturdy as hell and I may go as far as saying that it could intimidate some potential thieves just from looking at it hahaha. I highly doubt you'll get a better one here in Amazon for this low of a price. Definitely get it and use it as your 2nd lock if you have a mid-range bike($1000k) like me. Always use 2 locks. Always. It just makes it easier to ignore your bike for the lazy thieves who steal instead of work.

I like it. Looks very reliable 🤞Thanks.

We use this to provide an extra level of security when we park our Vespa. It's solid enough to give peace of mind no matter where we are.

Me gustó mucho el color es un color diferente a todos los candados en u adicional tiene mejor seguridad que varios amigos que tiene otras marcas de candados en u tengo que son ciclistas saludos.

Buen diseño y construcción. Muy conveniente con las 3 llaves. Buena calidad en general. Leí en reseñas anteriores que se traba al ingresar la llave, a mí no me ha pasado pero sugiero que le pongan unas gotas de aceite o grasa automotriz y seguramente se acaba el problema, eso pasa con cualquier candado que dejen a la intemperie.

Keyhole is protected by a plastic cover which is a nice touch, helps keep out dirt, snow etc. Lock is hefty...so there is real steel inside the silicon molding. It's a square-ish shaped lock, rather than a U which is actually helpful.Will work great on regular bike tires and most bike frames. Not able to lock through rear wheel of a 4" fat tire ebike though, need to use a cable with the U-Lock.Key turns easily and is well made. Overall the lock and key feel like a great product. I am not concerned with the key breaking off inside the lock, or the lock failing to turn or anything like that. I don't anticipate any issues with this product.

Pesa, pero pesa mas no tener una bici !!!

Bought 2 of these for our motorcycles. They fit thru wheel nicely and I like that they are silicone coated so they won't scratch the rims.Nothing will stop a grinder but this is as tough as a lock will get. Nice to have 2 extra spare keys as well.
