via velo Bike Lock Folding Steel Joints Bike Lock with High Security Hardened Steel Metal, Great Bike Safety Tool

its pretty good but an angle grinder would make short work of it but the same thing can be said for a top end kryptonite lock i beleive the record is 2mins.so save your money this will do the job nicely under most cercumstances.this is light weight easy to attach to the bike and is mid range security, these days its not about how secure your lock is its about where you park it up and how long you park it up.

Have had this lock for some time now, and I really like it. The mounting bracket is great, and I just keep the lock on the bike to use when needed, normally during short trips to the shops when the bike will not be left unattended for very long. The lock is long enough to go through the rear wheel and triangle, but to to lock both wheels.The only downside is that the rubber tab that holds the lock in place in the holder has started to crack, and I am not sure how much longer it will last before it breaks.

Really like this. Reassuringly heavy, light enough and compact enough to go unnoticed in its frame or in my backback for social days out on the bike. Not quite light enough to go in my back pocket - but that’s not why I bought it, as I’d never dream of going for a ride and spending long enough time away from the bike in my Lycra. For its purpose: perfect. So much so I bought another for my wife.

Folding lock designs are great because they don't take up much room on your bike - you can easily clip them to the frame and they stay there. They're easy to use and stronger than most cable locks. This one is flimsier others I have used, but it is strong enough to the job. However, after a couple of months, the lock started to jam and now won't unlock. Fortunately this didn't happen when the bike was locked up.In short, pay a bit more and get a stronger, more secure and reliable version.

Just the job! Light, strong, folds up small to stow away on the bike and long enough for most all bike stands.

Excellent, strong light and easy to use.

Weak lock holder.

Love it
