  • Firm & easy to use
Size: 5.9 x 2.6in Lock with 6ft x 0.4in Cable
Nice quality. Has a good weight that won’t damage my bike, came with two spare keys & instructions on best way to lock up the bike. Hoping it’ll be a good short-term deterrent. Only noise is from the slide to put the key in & clicking when unlocking.

  • Tired of running out of room.
Size: 7 x 5.5in Lock with 6ft x 0.4in Cable
The U-lock system I was using before was wonderful first time out... with my new mountain bike (which I haven't ridden a bicycle in 30 years, nor needed a bike lock). I love cycling and I was even more impressed by the improvements of bicycle locks. However, within the first week I started running into space issues...or better put, limitations on how I can secure the bike with all of the releasable and detachable parts. The extra wide width and angular shape to the U-lock really opens up more consistent fastening when locking the bike up. The shape and the added room even allows for my bicycle helmet to be secured along with the bike (helmet has a special location where you can secure the helmet in a bike lock). Overall this U-lock system's strengths are quality material (improving security and protecting the paint finish of your bike)...price very competitive from more recognized brands...carries a weight and durability that is reassuring (for the owner) and discouraging to all other people from tampering with it. ... show more

  • Good Quality U-Lock w/ 6' Steel Cable
Size: 7 x 5.5in Lock with 6ft x 0.4in Cable
Heavy duty u-lock with 18 mm shackles, twe sided locking points with good quality .04mm 6' long wire cable. Love the secure build and wire cable for locking up the front wheel and seat. Due to heavyweight build, the lock is pretty weighty and needs good quality frame holder or carried in backpack/rack bag ... show more

  • Solid Time buyer / deterrent. But can be odd to store it during rides
Size: 7 x 5.5in Lock with 6ft x 0.4in Cable
There are 2 types of lock shoppers. People who really believe that the lock will stop a thief who has the time and the tools. And people who knows the purpose of the lock is to simply deter/buy them enough time to either get back to your bike or 1. Someone notices your bike is being stolen and scares off the thief. 2. The lock is durable enough that it buys you enough time to tire out whatever tool they are using to steal it. That’s all a lock can do. Is deter a thief because it’s durable or intimidating. Or it can buy you time so you can get back to your bike or someone scares them away. I got this lock for those two reasons. This cable and pretty much all cables are literally a security joke with the right tool in hand. But lets be real it’s a valuable deterrent when you understand its use (to buy you time or to deter): Which is to secure your wheels/tires up so that some miscreant can’t just come and take your wheels off without tools esp if you have the quick release. That’s it. That’s all. I would never use this level of lock and trust it to be there when I get back in some random place where people are not around or that I Don’t expect to be back within 10-15 mins. I mainly use it to make quick stops into stores Where people are surely out and about at all times and where it would just be too crazy to use an angle grinder in public on a bike. In my personal opinion I would eventually get two of these locks and I would trust that setup to secure my bike if I intended to make longer stops or in more sketchier areas. It’s not about if they can get thru the lock (someone always can) it’s about how much time you can buy before they can take it and deterring them from attempting all together. The size is good and Wide and have fit around the posts I’ve used them on so far. I appreciate the door that covers the actual lock so debris doesn’t deteriorate it over time. (I ride to the sandy beach daily so I really appreciated that) Only thing I Don’t like about it is that it’s pretty challenging to find a good place to keep it on the bike since it is so wide and oddly shaped. It didn’t come with a mount so I currently have it hanging from my handlebar. And I Don’t really care for that placement AT ALL but it’s the only place that it will fit on the bike without rocking and knocking everywhere. Will update this if anything changes. ... show more
