The Bike U Lock is sturdy and does its job for the most part. The 16mm thickness gives some peace of mind, and it feels solid when locking up the bike. However, the lock mechanism can be a bit finicky at times, and it takes a few tries to get it to close properly. The size is a bit small, so it's sometimes tricky to lock both the frame and wheel. Overall, it's a decent lock for basic security, but it has a few limitations.

The lock is sturdy and I especially like how there’s a small cover for the keyhole so that dirt and grime don’t enter while riding.

I was worried given the low price that these would be of lower quality, boy was I wrong. These things are extremely solid, well designed and built, and all at a great price. I bought 3 of them and all 3 are great.Very rare to get such good quality at such a low price.

I bought this lock specifically to secure my helmet to my cycle when I want to leave it with my bike. The lock fits easily inside the storage compartment. I especially like the orange slide that covers the key hole to keep it clean and dry, and also that three keys are provided. It's a strong, quality lock for the purpose I bought it for.

The lock I received was a little broken from side where there’s a plastic part. Also the plastic used is not good for last long. Cost A little higher than the quality.
