ROCKBROS Anti-Theft Bike Cable Lock, Black, Portable, Key Lock, Rustproof

Good lock for 10-15min in nyc 1-5 min tops a quick run into a store if you have a sights on your bike in nyc 10min not and overnight lock it’s for quick stop locking. Also I wouldn’t use this on a bike worth more then 500$ even for quick stops

I like this as a deterrent. Obviously I wouldn’t use it to leave my bike somewhere overnight or for several hours, but it is a nice option for me to like the back wheel to the frame, a helmet lock, or to use with another lock cable when I don’t want to carry my heavy u-lock. Great value

Good quality. I lock my rear tire to frame (stays in office). it barely fits on my mountain tire, but it does the job. I think it’ll be a better fit for thinner tires, but I love it! I also love that you just have to push down on the nub to lock it….perfect.

Might have been nice if it could fit. Too small to secure the bike frame and tire.

good lock smaller than expected..sturdy and secure

I love this lock. I had to have it even though I really didn't know the true value of this lock until I bought it. It's so much easier and far more practical to lock both wheels with two of these locks. Anyone who has a thought of stealing your bike, will now have to deal with three locks. They can't wheel it away with both tires locked and the mainframe too. I use the AWESOME MASTER LOCK BLACK PYTHON CABLE for the locking the mainframe and bike seat to a pole. I've got it made. It's just not worth the time for someone to try and steal it with 3 locks. The size of this lock doesn't make any sense, until you have it in your hand and then you see the value. Go For it. You will love that you did. You don't even need the key to lock it, just to unlock it. This circular lock is wonderfully practical, You'll see.

I use this lock everyday. I have an outside fridge I do t want the kids getting into, and this lock works perfect for that. I keep the key on the fridge. I’ve had it over a year now with no issues. It feels like the inside has metal things inside as well, so if I ever need to cut the lock I’m not sure how I’ll do that *knock on wood*. Easy to use, durable. Buy it if you need a lock!

Excellent quality/versatility... make sure of your measurement of application !!!

far out...I like the idea and design but It's just too small. I run 2.8 wheels which aren't ridiculously fat or anything on my e-mtb, and I can only fit this on the tire. Not the tire and frame which would be actually useful. Assuming a thief got through my main lock, having this on solely on the wheel you could actually still ride my bike away by just twisting it so the lock part is in line with the rim/ spokes (though probably would be a bumpy ride). If they had only made this just two inches bigger, it would have been great - but no, you probably need to buy two in you're running bigger wheels, it might be ok for 2.4 sized wheels and depends on the geometry of your frame too. I'm probably going to return this as it's really kinda useless for me and offers little protection.
