Master Lock Black Bike Lock with Key, Standard Size U-Lock for Bicycles and Other Outdoor Equipment, Anti-Theft Lock for Bikes, 8320D

Simple and nice locker. I sued for a scotter but also fits a bike easily

Absolutely love this lock, the thickness gives me ease of mind. Quality is tip top especially for the price you pay for it. Comes with keys and holder for your bike that you can install. The bar unlocks from both sides making it very easy to install and unlock your bike from racks.

This does exactly what it's supposed to do. It works great, I bought it for my son who has not been the most responsible with keeping bikes. This helps.

Very sturdy but a little awkward. Just takes some getting used to. The key unlocks both sides at once instead of a drop and pivot sort of thing like a padlock. So you have to make sure you’re holding the bar when you unlock it. I’m using it to secure a deck box to a rail post and I’m on the third floor so it would be dangerous if I dropped it so it’s a little awkward for my use but I like that the bar is thin enough to get through the D-ring on the box’s bracket.

Good deal for a master lock product is always a safe bet. Like literally never bought a bad master lock product that just doesn’t happen as a general rule of thumb. I feel like this will do better for safety against theft then just a regular wired bike locks are easy to cut through for thieves.

Great lock. Needed it for my scooter and never failed me once over 1 year of use. Couple of my friends had a wire lock and their scooters unfortunately got stolen. The lock is very durable, and it comfortably fit around my scooter with no struggle. Also, had to ship the lock across the country in the same box as the scooter and it did get banged up a bit with visible scratches but it didn't affect the durability at all! Ended up forgetting my key at times too, but luckily they give a backup key! Only concern would be that the key is annoying to use sometimes, but never bothered me in any significant way. Definitely recommend.

This U-Lock came with a mounting bracket as-well, which was able to be used on the handlebars of my electric scooter. It’s not too heavy and comes with a pair of keys attached. It seems pretty solid, and so far hasn’t made much noise when moved! The U-bar has just enough space where it can accommodate a bike rack of many sizes.

It’s good but not that much quality I mean it’s good for the price

The Master Lock Black Bike Lock with Key impressed me with its solid construction and sense of security. The lock's quality was apparent from the first use. While I haven't had the unfortunate need to test it against actual theft attempts, I felt confident in its ability to deter thieves. The lock felt very sturdy, and I often tried to pull it apart with my hands to test its strength, finding it very resistant to force. The lock features an integrated disk keyed locking mechanism, which was straightforward to use, though I'm not entirely familiar with the technical details of this mechanism. However, each time I used the lock, it required a bit of effort to lock and unlock efficiently. This could be due to the lock's solid construction, which, while providing security, also made it slightly cumbersome to operate. The description mentioned a vinyl coating, which I'm not entirely sure about in terms of its function or appearance. However, the lock looks well-made and durable. Its weight is significant, which is a positive aspect in terms of security but made it inconvenient to carry in a backpack. Instead, I opted to hang it on my bike during rides, avoiding additional weight on my back, which could affect my riding comfort and speed. Overall, this lock represents a good investment, particularly compared to cheaper alternatives I've used in the past, such as those from Dollarama. It offers a higher level of security and build quality, making it a valuable addition to my biking gear.

prima schloss...funktioniert gut.

Practico y economico, funcional y seguro

For this price this is a great lock, I have been using it for a few years in the city and have had no thefts or issues with the lock. It is a bit heavy but this is to be expected for a metal lock.

Don't recommend this product at all, the holder broke after less than 5 uses and the quality of the lock doesn't seem great. Better to spend a bit more and get something decent.
