Sportneer Bike Lock - 17mm Shackle Heavy Duty Anti Theft Bike U Lock with 2 Keys - Bicycle

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. Read more

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. Read more

Perfect for my Lectric XP Step-Thru 2.0! It's the perfect size, weight and has a great feel to it. I keep the keys on my car keys, so I always have them. The lock feels strong and seems like it would be a lot harder to cut through than a traditional chain, if you are locking up an expensive bike, this is the right U-lock for you. It took me months to compare and find the perfect lock and I'm happy I found the one I needed. Very happy with my purchase and would recommend this to anyone who needs it! Read more

It's a very good, sturdy lock that would probably take a Thief a while to cut through. There are a few issues though that I find with this product. The first is the length of the lock. For most Bike racks that I've encountered, the lock seems to be just a few inches too short to get the rack and the bike wrapped around to then lock it. The second is the cable. Even if I were to use the steel cable in conjunction with the lock, all someone would have to do is cut the cable (if able to), rendering the lock useless because the lock would just slide off the cable. There may be more strategic ways to place the lock so that a Thief wouldn't be able to ride off with it such as possibly compromising the front or back tire with it and wrapping the cable too, but I think more of my gripe comes with the length of the lock. Then the cable may make sense when wrapping it around the Bike. I ended up getting a folding lock that's longer in length. So I use that together with this lock so Thieves may think twice before trying to take on multiple locks on a single Bike. Read more

Works great. Key lock. Strong. Read more

Make no mistake this is not a very secure lock, your bike will be stolen if you rely on this for long term outdoor storage. But it is a very handy little lock with a nice rubber coating that won't damage your bike and from 10 feet it kind of looks like a high quality U-Lock which is a protection in a way. 5 stars as a cheap, handy, portable little short term lock to scare off opportunistic bike thieves while you get coffee. 0 Stars as a serious lock for long term storage.
