    Lifelike Core Flex

    A necessary purchase, my bike insurance specified Sold Secure Gold Rated and this was the lightest and most portable lock available. I’ve now taken it out on 2 rides and worn it around my waist. Whilst it is heavy (1.7kg) it does sit well on the waist but it is quite a bit of extra weight to be riding with and is quite lumpy. It is stiff to manipulate but maybe that will ease with use. It certainly is a sturdy lock but it’s a shame it weighs so much.

    nice design

    main minor negative thing is that the lock size makes it slightly tricky to get through wheel/spokes without a fiddle

    otherwise a nice piece of design!

    confident with the best

    long been a fan of Litelok bike security lacks, after all they are made in Wales. Beside that, the research & development into security & impeding bike thieves is impressive as well as comforting to a bike owner.

    The Litelok Core flex is the perfect compromise of security & manageable size. It fits perfectly into a pannier, it maybe weighty, yet that is the degree of security within its design. Locking up my bike is like giving a signal - give that a try to nick it before I return, no chance !

    Excellent - 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.

    peace of mind

    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!
