This review is from: Kryptonite Evolution Series 4 U-lock with FlexFrame bracket (Sports)
And if it does not, why not? This lock is (so) heavy, (so) substantial that requires 'guns of steel' (that's biceps, by the way) to use it everyday.
Truly a secure feeling lock that should ideally combined with a non-Kryptonite lock to thwart (or at least delay) those pesky bike robbers. The keys (three in total) are firm and solid (but read the instructions: "don't be hasty in twisting the key too quickly"), and the single key LED night-light is a nice touch.
I cannot judge on how well the lock's frame mounting/housing works as I have a water bottle attachment in the most suitable location.
The lock comes with a UK warranty (lifetime) and an option to either apply for a free key registration or a free £1000 protection for one year (if stolen you are required to submit a UK Police Crime Number, the lock, receipt for bike purchase, etc. to the manufacturer). This is may be useful for some people though a deterrent of a large Official sticker (visible on the frame) and UV permanent marking from the UK Police's free BIKE REGISTER program may be even more useful.
Overall, this Kryptonite Evolution Series4 Flex Frame U-Lock is the peace of mind that I was seeking below £35.00 (at the time of purchase on Amazon.co.uk).
