I’ve been using this lock daily since it arrived, and I’m genuinely impressed. The matte black finish that looks cool and low-profile on my bike which doesn’t draw too much attention, I actually like that for security reasons.The U-lock is thick and really sturdy, and the included cable is great for securing the wheels or looping around poles. I also appreciate that it comes with two keys, with a simple turn and it’s open, which makes locking up quick, especially when I’m in a rush (always)The mounting bracket is a nice touch too and easy to install and holds the lock snugly while I ride. Overall, it’s a solid and dependable setup, and I feel like my bike is way safer now.

After extensive research, I chose Sportneer’s heavy-duty bike lock, and I'm so glad I did. This lock is impressively robust, featuring a solid 17mm steel shackle that gives peace of mind against theft—even in urban areas known for bike crime. The included 5-foot steel cable is a bonus, allowing me to secure both my wheels and frame simultaneously. The lock mechanism itself is smooth and secure, with keys that turn effortlessly without jamming, which can be a common annoyance with cheaper locks. It also comes with a convenient mounting bracket, making transport easy and stable when cycling around town or trails. Overall, a fantastic product with excellent build quality, ease of use, and impressive security for its price point. Highly recommend for city cyclists, commuters, or casual riders who need dependable theft deterrence.

Good manufacturing standards and materials. Affordable and effective security for your bicycle. The dimensions of the lock are perfect for all bicycles when used to lock the rear wheel and frame together without any damage to the painted metals. All steel materials under the thick plastic coatings on the steel cable and steel locking mechanism. I feel like I am back in high school when I rode my bicycle to school most days of the week. I bought this for my new electric bicycle and folding bicycle, when needed, to replace an old defective U-shaped lock. I have my electric bike secured to a huge steel support inside the garage since I had a bicycle swiped back in 1980 from my parents garage but the Police actually recovered it. Not taking any chances.

Solid U-lock, very light for its thickness and easy to carry, but should only be used for 700c or road bike wheels. This isn't wide enough for MTB tires, as I use it on my ebike w 20" wheels and BMX tires (2.4") and it barely can squeeze past them. Works well, I use it in conjunction w 2 other ulocks for the other wheel and frame.Please do not use cables ever to lock anything, they are about as secure as twine. Just use the u-lock, its' decent.

The lock itself is solid and well-made, especially for the price. It feels durable and offers good security. However, the mounting bracket doesn’t fit my scooter, so I can’t attach it as intended. Still, it’s a good value overall.

I bought this for my electric bike, and it works great. It is a great length to get around a pole to lock up. I definitely would not have wanted something shorter. It is very sturdy and easy to use. I feel confident locking my bike up and going into a store or restaurant.

Sturdy lock that's not too big but can lock my bike up to street bike racks without a struggle. Keys work fine but still can't find a way to mount on bike with angled crossbar... I would buy again except this will probably last for years.

Seems to be durable, heavy weight and sturdy, easy to use!
