Review: Feels secure and reliable, worth the extra weight - This is a seriously solid lock that gives you a real sense of security. The U lock alone is thick, heavy, and feels virtually tamper-proof. The included flex cable is a great addition, giving you more options to loop through your wheels or around awkward railings or posts. I’ve used it to lock both my frame and rear wheel with the U lock and then looped the cable through the front wheel. That versatility makes a big difference in urban areas where secure anchor points aren’t always ideal. While it is heavier than cheaper alternatives, the added weight feels justified by the protection it offers. I’d much rather carry a little extra bulk than come back to a missing bike. The lock mechanism is smooth, and the key turns easily without sticking, which I appreciate after past frustrations with cheaper locks. Pros: Heavy-duty and high quality Flexible locking options with included cable Smooth key operation Cons: A bit bulky for smaller backpacks It might be overkill for low-crime areas
Review: Solid and Reliable Lock — Worth the Price - My husband said it Feels really sturdy and well built. The lock mechanism is smooth and doesn’t jam like cheaper ones he's used. It’s got a good weight to it without being bulky to carry. It gives him confidence leaving his bike locked up. A proper bit of kit if you want security and peace of mind.

### ⭐⭐⭐⭐⭐ Solid and Reliable Lock — Worth the Price
*by K***E on 7 November 2025*

My husband said it Feels really sturdy and well built. The lock mechanism is smooth and doesn’t jam like cheaper ones he's used. It’s got a good weight to it without being bulky to carry. It gives him confidence leaving his bike locked up. A proper bit of kit if you want security and peace of mind.

### ⭐⭐⭐⭐ Can’t mount on an upright woman’s bike
*by J***X on 10 May 2023*

The lock is excellent in how sturdy it is. It’s a good deterrent. However, it’s not the easiest to lock and unlock and is impossible to mount on an upright ladies bike with the mounting provided. It’s also very heavy. However, it’s easy enough to put in a pannier. Having two cables is also a godsend. It’s a good, solid lock and would buy again if my husband ever decides to get a bike too.
