Gold Rated FLexible Bike Lock
For long periods or in high-risk areas
Our Boaflexicore+ secure strap withstands sustained attack with layered protection including a plant-based polymer, radial reinforcement and high tensile core joined to an aerospace grade hardened steel inline lock body.
Our patented radial reinforcement not only protects the tensile steel core within, but it also flexes in sync to retain maximum flexibility without compromising on security.

Great Quality, High Security, Value for Money, Wearable, Made in BritainRated 5 out of 5 starsExcellent - does the job
Did a lot of online research before settling on this. It needed to be relatively lightweight and easily carried but still meet the Gold standard. Lightweight is subjective, but this although still quite heavy is lighter than a lot of other options out there. It is classed as wearable security and can be attached round waist. Have done this once and didn’t find any issues. It wasn’t uncomfortable and didn’t feel that heavy, probably because weight is evenly distributed around your girth! Most of the time when I need the lock I will have a small rucksack and the Litelok Flex fits very easily and again doesn’t feel too heavy. You notice it initially when you pick up the rucksack but once that is around your shoulders I hardly notice it. It is very well made and I imagine that anyone wanting to steal your pride and joy wil have a very tough job cutting through the Litelok. It is nicely protected with a sleeve and rubberisation of the lock casing. There is a small sliding rubber seal that stops water ingress to the guts of the lock. A very nice feature. It is a little on the stiff side so attaching it to your bike could be easier, but have a quick practice and you’ll get it. All-in-all, I am very pleased with my purchase and would recommend.Product QualityRated 5.0 on a scale of 1 to 5Ease of UseRated 4.0 on a scale of 1 to 5

incredibly secure, and once I had a practice and worked out how to hold and lock/ unlock it all has been fine. It would be amazing if it was more flexible and fitted between the spokes on my bike, but then it would not be as safe and I can not have it all!Product QualityRated 5.0 on a scale of 1 to 5Ease of UseRated 4.0 on a scale of 1 to 5

It is heavy to wear around the waist but I got used to it.
Too short to fix around a lamppost, and rather inflexible so care must be taken passing through a wheel between the spokes. Otherwise I’m happy.Product QualityRated 5.0 on a scale of 1 to 5Ease of UseRated 3.0 on a scale of 1 to 5

I regret buying this lock. It is not very flexible - it takes a lot of strength to coil it into a smaller round and then secure it with the velcro straps. I have tried to fit it to the frame of three bikes (e-bike, touring bike and commuter hybrid bike), and it will not fit any of them so I end up with it taking up a lot of space in a pannier.
It is very sturdy, no doubt very secure, and seems well made. The lack of flexibility makes it challenging to lock a bike to a rack.Product QualityRated 5.0 on a scale of 1 to 5Ease of UseRated 1.0 on a scale of 1 to 5

Not too heavy. Have to put some effort into twisting it through the spokes, round the frame and round the fixed post. I want another longer one but they seem to be totally out of stock everywhere!Product QualityRated 5.0 on a scale of 1 to 5Ease of UseRated 4.0 on a scale of 1 to 5

I had one before (everything was stolen using an angle grinder) but this replacement is much stiffer, harder to get through spokes, and much less comfortable to wear as a sash. I combine the two as I prefer it to around the waist - I'm not 'big' but it's a tight fit if you're not skinny.
I also preferred having one key instead of two for both locks.Product QualityRated 4.0 on a scale of 1 to 5Ease of UseRated 4.0 on a scale of 1 to 5LULITELOK UK1 month ago
Thanks for your review. We just wanted to check that you're using the wearable kit with your Core Flex? This should allow some flexibility in the fit of your lock when you're wearing it.

E-BikeWhat do you like about this lock? High Security, Great QualityRated 4 out of 5 starsGood lock, but the body is too big to fit a standard extension cable through.
I'm please with the lock itself, it's a very sturdy bit of kit. Unfortunately I am used to using a cable extension (Kryptonite Krytoflex) to wind through my front wheel. When I had a U lock this solution worked very well, but the body of the Litelok is too big to get through the loops of the cable.
I was hoping Litelok might have been able to suggest an alternative (like why don't they make one themselves as an add-on?) but they were unable to suggest any alternative.Product QualityRated 5.0 on a scale of 1 to 5Ease of UseRated 3.0 on a scale of 1 to 5

I just received the locks (2 75mm locks) late yesterday) and will be out riding around with my e-bike today.
They are quite heavy duty and somewhat stiff. But, if that is what I need to avoid getting my $4k Evelo Atlas e-bike safe, the so be it! I also have a Krytonite ulock. I will use the ulock to lock to a secure location and the two 75mm LITELOK COE FLEX together around the wheels and frame/ulock.
I will finally feel safe and secure!
