Sportneer Bike Lock: 8mm Thick High Security Anti Theft Bike Chain Lock with 2 Keys- 3.2/4ft Long Heavy Duty Anti-Cut Bicycle Lock for Bike, Motorcycle, Bicycle, Door, Gate, Fence, Grill

Best bang for your buck when it comes to bike locks. It’s so easy to use, it comes with a spare key. It has a plastic cover for the keyhole to cover the Lock when you leave your bike outside, that way even water and other debris can’t get inside the key hole. Ive gone through 3 bikes already (sadly the crank arms keep breaking since I ride the bikes to hard) but this lock just keeps going. It’s outlive 3 of my bikes so that alone should speak to the quality of this bike. The design is very nice as well the cloth cover is a nice touch so is the black color. I find the length to be just right to lock one bike and barely long enough to lock two bikes with it. However sometimes some poles are too thick to accommodate both the bike and the lock but I somehow make it work.It’s a good lock yall, I highly recommend this. Also the lettering fades away quickly but that’s because I use my bike everyday and always lock it up under the hot sun or in the rain

Incredible product, a friend recommended it to me, and it's really worth it, price-quality ratio. My scooter was almost stolen, and the chain prevented that from happening. It's resistant to chain cutters. I'm attaching photos of when they tried to cut my chain and couldn't.

Wraps around from of my bike well for storage. 12 uses out of it going up rocky hills to the gym, in which case it stays untouched and unmoved when in use there. The length is great, allowing me to lock the bike to things I shouldnt be able to otherwise. Feels a bit cheap when turning key, but may be due to the dual sidedness of the key. Overall, good product. I will update this review if something goes wrong.

It’s too short, the quality is good, it’s not hard to use, and it gets the job done. I’ll have to get a longer one.

Love the chain it's ideal for protection for bikes of any kind

Since the day I received this product it’s been good to me. It’s a chain so it’s definitely durable and stands up to time. I was surprised how well the material around the chain held up. The length is perfect to love my ladders on the rack. The key and slide are easy to use. Never had a problem in cold weather so it functions well. No sign of rust yet and I use them almost every week. It’s a little heavy but I’m ok with it because it won’t be easy to cut

Great to lock 2 bikes and even 3. Tough and durable. Doesn't scratch bikes.

Feels heavy and strong.
