3 Stars Lock – OK. Lock bracket – JUNK!
During the first ride I had with this new lock attached, it flew off after I hit a bump. I had it mounted horizontally on my top bar. It was dragging underneath my bike, and thankfully there were no cars coming. Most of the rubber got scraped off a section the u-bar and sections of the cable, and the lock rattles now. I have since moved it to my seat post, which allows it to be mounted vertically. In other words, the bracket is total junk. As far as the lock goes …we’ll see. I still have my bike, so far.
2 Stars Lock might be strong, but everything else is cheaply made
This lock is being returned to Amazon. I’m surprised by the cheap quality of the accessories that go with this lock.
Problem 1: The keys are made of plastic and painted silver to look like metal. Plastic breaks, which is why some people are having problems with the keys breaking off in the locks.
Problem 2: The key light lit for 3 seconds then went off permanently.
Problem 3: The attachment to hold the lock to the bike is large, ugly, and poorly made. There is no ring of metal or plastic with a rubber inside that is used to attach most accessories. Instead, this is a large piece of plastic and a thin nylon strap that you tighten to the bike. Unfortunately, it flops around while riding. Also the attachment to the lock itself is cheap plastic that can easily come undone going over bumps.
Overall, I’m taken back by the cheap, inferior quality of the keys and bike attachment. The lock would definitely need to be carried inside a bike bag, and a person would need to be careful not to break the keys, especially as the plastic stresses over time. The lock itself might be secure, but the overall quality of the package I received was surprisingly bad.
Edit: After looking at other inexpensive locks from companies such as Kryptonite, I’ve noticed that these sorts of problems are actually pretty common. The solution I used was to get a much more expensive Kryptonite lock.
5 Stars Excellent, Safe Lock
The Lock is VERY sturdy both in design and material.
The thick cable gives extra-assurance your bike is safe.
Of the 6 keys provided, one has an LED light attached.
The attaching bracket is functional but could be better in both instruction and design.
Overall: The Lock is excellent for any medium to low scale bikes. For better protection I would recommend Kryptonite New York Fagettaboutit U lock. A definite must buy for the price.
4 Stars Great lock
I would give this 5 stars but I have only had it one month so hard to say if it holds up in the long run. So far I find it well constructed and doing the trick.
4 Stars 1st Bike Lock
This is my first bike lock for my Diamond Back Response Sport 08. The reason I got it is because I usually ride my bike to the lake and like to jog also so I have to leave it locked some how. So I saw the nice price and got it. The U lock is heavy, the piece you attach to the hold the lock to your bike in place is really poor its basically a strap that you tighten to your frame and and a clip that holds the u lock in place while riding. The strap/clip item failed. It doesnt lock in place and the u lock falls out BUT thankfully I found a better way to attach it to the bike just by locking it to the frame and using the cable from one end of the bike to the other. This is my first lock, so as far as the holder it all really depends on your frame of bike so larger the frame the easier it is to fit/attach the strap to it, but the clip part is weak is made out of plastic.
