Bike U Lock - Sigtuna Bike Lock Heavy Duty Anti-Theft with 4ft/1.2m Cable, Bicycle U Lock with Sturdy Mounting Bracket for Mountain Bikes, Ebikes, Scooters

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 backpackCONS:-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.

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.

Looks secure, strong and well thought out...c

I bought a 16mm Sigtuna U-Lock with 12mm steel flex cable two weeks ago, and have been using it everyday since to lock my bike whenever I am biking around my university's campus and parking on and off at different locations. So far, I've been very impressed by the sturdiness of the U-Lock. It feels robust, is definitely robust, and secures my bike. The key also slots in easy, and it is super convenient to lock and unlock after parking my bike. As far as U-Locks go, Sigtuna's 16mm one ticks all the boxes, and does what you'd like a U-Lock to do extremely well. I have no complaints. The 12mm steel flex cable is of a good length, and also does its job.On a minor note however, the U-Lock is quite heavy. I am sure weight is a necessary quality for robustness (which I would prefer not sacrificed), but it would be nice to have a lighter U-Lock. The weight adds a noticeable amount of weight to my bike when biking, and can make it painful when the U-Lock falls on my foot while in the process of unlocking the U-Lock. The velcro strap, to strap in the steel flex cable onto the bike frame, is also not particularly effective.Offering U-Lock's with greater heights on your website would also be helpful. 16mm is good enough to lock my wheel against a rail, but leaves no room for me to lock both my wheel and frame together (provides much more security) against a rail.

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 thievesCons:- 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 tornOther 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 thatOverall, 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.

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.
