Review: Great lock, poor mounting bracket, Fantastic Customer Service - I got this lock to replace my old Keeper 2. Both locks are great for locking bicycles, nothing short of power tools will get past them. And power tools are conspicuous. The keeper 2 was a great lock, despite the key sometimes being sticky, but the mount that came with the lock wouldn't fit on my bike well and wore out over time. Eventually, it fell off the mount while I was riding my bike, and I was unable to find it. I bought this lock to replace. Already, this lock is of a noticeably higher quality than the keeper 2. There is a plastic covering for the keyhole to prevent wear, it is much sturdier, and the locking mechanism itself seems more solid. Again, however, the mounting mechanism is tedious to set up (I can't get mine on correctly again, it is weirdly designed and I couldn't find any instructions for it), but it seems to be of a higher quality than the one that came with my keeper 2. I am still, however, worried that after prolonged use the mounting mechanism will wear out and the lock will fall out again, but that's nothing against the lock itself which is what you really pay for. What gets this lock 5 stars is the customer service. I had ordered the theft protection that came with my keeper 2, which cost a few bucks (15ish?) for 3 years. I was worried that my protection as tied to the lock, but after 2 minutes with the rep I had already given her the information on the new lock and she promised me she would transfer the coverage. I also only had to wait on hold for 2 or 3 minutes, which for any customer service is a huge plus.
Review: Great lock. Long enough for my hybrid upright position bike. - I've been using this lock for 4 or 5 months now.... Gets 5 stars in consideration of reasonable price... I've seen flimsier locks for about the same price in stores The Pros- 1. I have a hybrid upright position bike and for the those familiar with these bikes you know there tends to be a greater distance from the frame to the tire making it necessary to have a longer bike lock to secure both onto bike parking racks. The length on the lock works great for this purpose. Areas of concern, but not a deal breaker as far as I'm concerned 2. The flex frame bracket is flimsy but if secured on the right spot and tightly it will work out just fine. Took me a good deal of time to find the right spot since I'm INCREDIBLY not manually inclined as well as the initial installation about an hour or so *(disclaimer it does come unloose and requires tightening from time to time and I also require a reusable zip tie to secure it to frame else the lock would hit my leg) it works because I managed to rest it on the water bottle holder screws as well..... don't know if it would hold otherwise??? again not manually inclined and I managed to figure it out so you can probably as well. instructions are useful enough to get the job done. Cons- 1. a bit heavy.... not a big deal.... there is no way of getting around this because of the length. 2. the locking mechanism can be less than perfect at times but goes away with regular use. Not as big of a problem as others have noted here. ((***** have not rode in freezing temps yet.... all and all this is a good bargain for the price without going with your more expensive and heavier alternatives considering the length of the lock. Hope this is helpful

### ⭐⭐⭐⭐ Solid and Convenient Bike Lock
*by S***C on August 12, 2025*

This lock is very solid and feels extremely sturdy. It’s also long enough to easily secure my bike to various racks or poles, which makes it very convenient to use. The only minor drawback is that the key can be a bit stiff at times, but that’s a small issue compared to the overall quality. Overall, a great lock that gives me peace of mind.
