Sportneer Bike Lock: Heavy Duty Anti Theft Bike U Lock with 5ft Security Steel Cable - 17mm Shackle Bicycle U-Locks with Keys & Sturdy Mounting Bracket for Road, Mountain, Electric & Folding Bike

Great lock, very thick, sturdy, and secure. I think it’s a perfect choice (for in my case) a scooter. I am able to double secure it. Works great and is easy to use. Overall, really happy with my purchase and felt like it was the perfect choice for me and my scooter.

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.

Lets be honest. EVERY LOCK even ones costing well over $100 can be broken into within seconds even by nonprofessionals. Locks are only to stop honest people or maybe very young kids from making bad choices. This Lock is ok for the price but it has a couple drawbacks. It locks on both sides of the U which is better than many but the U is not very long or wide so it could be difficult to directly mount your bike to a bike rack or stationary object. It is not big enough to secure Fat tire bike wheels. Its a basic lock and I would probably buy it again for the price.

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!

Decent bike lock. Bought to use with my e-bike. Not all locks are thief proof so also put a air tag inside the frame.

This bike lock feels strong and well-built. It gives peace of mind knowing my bike is secure whether I’m leaving it outside for a few minutes or longer. The lock mechanism works smoothly and is easy to operate without sticking. The length and flexibility of the cable/chain make it simple to secure the bike to various posts or racks, and the material feels durable enough to resist casual tampering. It’s also compact enough to carry on rides without being bulky.

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.

Good quality product as per specifications

I liked it, good quality, good price, fits well under the seat and fast delivery. It is recommend but make sure of the size of your seat pipe and space otherwise mount it differently.

Seems decent and secure enough, very heavy lock as well.

D-lock and cable set works well. Two keys provided.

Very impressive product. Weight is a good thing and it's really heavy duty and the rubber layer is very thick so it's really tough. Comes with 2 keys to unlock and lock it, very easy to use and very safe. Just go for it.
