The Kryptonite Evolution Series 4 U lock with FlexFrame
bracket will keep your bike safe thanks to an impressively sturdy construction
that will deter even the most determined thieves. The lock is Sold Secure Gold rated
and comes with £1,000 anti-theft protection.
The patented double deadbolt locking mechanism provides
extensive holding power and the reinforced internal housing increases
resistance to twisting and leverage type attacks. There are three keys,
including one which has a handy light, to minimise fumbling around in the dark
and anti-rattle bumpers prevent any unnecessary noise and scratches.
What do we think?This will stop someone giving it a good go. The high vis makes it easily noticeable. It’s as if it’s saying to you “Don’t come near me – you ain’t gonna get it!”. For not much more money than the lower priced models, you’re getting a better security option which you can also use on a range of other vehicles. - Billy, Swansea Web Team This has a hardened double deadbolt which is really good. Kryptonite will replace your key if you lose it, which is good if you’re prone to misplacing keys. It also comes with a lifetime warranty for added peace of mind. - JT, Swansea Marketing Team
