  • Convenient Lock And Cable Holders. Easy Use.
Color: Yellow
Lock, cable, keys and holders included. Soft plastic covered cable won't scratch and easy to feed through frame, tire, and around a pole. My frame is too thick for the mount but was able to attach to the seat stem. Further, I don't even need to take the lock off the holder. Just unlock it, feed the cable around where I need it and back onto the lock. Working out great and should take anyone a little time to get through it. Seems to by a good value for what I got and a little piece of mind. ... show more

  • Sigtuna bike lock Rock
Color: Yellow
I have been using this product for 3 months now and it's been very reliable. It had been to many places, and still going strong and very reliable in keeping my bike safe. It does not matter if it is a bike rack, a post, a tree, or just a fence the U lock and the cable always made it work. I got my money's worth. The keyhole cover is a very nice touch. The cable and the U-lock is the star of the show. SOLID. Heavy but outweighs it's sturdiness. ... show more

  • Great secure lock, mounting could be improved.
Color: Yellow
The lock is very strong and secure without being too heavy. Mounting on the bike is very convenient but keep in mind that it does add some weight. The mount for the u-lock mounts solidly to the frame, but it does allow the lock to jiggle around a bit when you ride which can be a bit irritating at times. The mount for the cable lock broke the very first time I installed it, but I wasn't surprised as it is just a velcro band. I wasn't too worried about it as mounting it to my bike got to be too cumbersome anyway. The lock mounts nicely to my frame with just enough room to fit my bottle and without getting in the way of peddling. I lock my frame to the bike lock with the u-lock and run the cable through both of my tires. This has seemed to work well and is very secure. I also like that the silver cylinder in the middle can rotate to cover up the keyhole. This will confuse a lock-picker and at the very least add a few precious seconds if they try to pick it, which I think would be pretty difficult to do anyway! All in all I feel much more comfortable with this lock than I did with my previous cable lock that was cut and taken along with my nice mountain bike! ... show more

  • -The cable and lock are both extremely sturdy -The lock is very easy to unlock
Color: Yellow
I recently moved into a new apartment building known for having some bikes stolen, so I decided to invest in a solid lock to deter thieves as much as possible. This one does the job, and then some. The cable is long enough to wrap through both wheels, and the lock is extremely thick and solid, so I have no qualms about leaving my bike locked up. Some pros and cons: PROS: -The cable and lock are both extremely sturdy -The lock is very easy to unlock, and there are even two keys so you have an extra if you misplace one. -The lock twists to hide the keyhole out of sight which is a nice feature -I really appreciate being able to store the lock and cable on my bike when I'm on the move instead of lugging it in a backpack CONS: -This isn't really a con, but more of an annoyance: the cable IS long enough to wrap through both wheels, but I had a little trouble doing this with the way my apartment's bike rack is set up. Again, that's more me than the cable itself and it really is plenty long. -I had a bit of trouble securing the storage bracket to my bike. It kept slipping down on the frame, but I was finally able to tighten it enough and haven't had an issue since. Really, five stars here and no complaints. Great lock for a great price. ... show more

  • Great purchase at great price point
Color: Yellow
This review might be helpful specifically to customers living and biking in NYC. I recently purchased a bike. In fairness, my bike was purchased used and is a basic Giant women's bike. But it's in great shape and definitely an attraction for thieves. I've been using this lock for two weeks now. Here is a list of pros and cons: Pros: - Flex cable is great in securing both wheels - In order to get through the lock, a thief would have to cut both sides of the "U" - Built-in protector for wear and tear of keyhole against weather elements - Unbeatable price point for the whole package - Lock bracket provided - Doesn't weigh a lot (compared to other U-locks) - Once secured, the whole contraption looks formidable and is hopefully a deterrent for thieves Cons: - The lock bracket is of low utility if you also want to secure the flex cable along with the U-lock - The velcro strap provided to secure flex cable was not great. It's already torn Other observations on U-locks in general: - My bike is a step through (not a diamond frame). It is hard to really find a place for the lock bracket, so it's kind of useless to me (but this would be true of all U-locks). So I just secure the U-lock around the bike handle - You might want to buy a bigger size if securing in NYC. I am able to manage with this lock and flex cable, and I did not want the extra weight of a bigger lock. But sometimes it is challenging to fit the "U" around street bike racks and I spend a few minutes doing that Overall, a great purchase. If bike gets stolen despite this lock and cable, that's just bad luck. I would recommend and would also consider buying again if I am in need of another lock. ... show more
