Review: Good product - no issues - I’ve had a Kryptonite lock with this type of bracket for a few years and it’s been fine. I needed this one so that I could transfer my lock between bikes. In the pack there is a little slip stuck to one of the parts with a QR code that you can use to access installation instructions. These are pretty good but if you do an internet search for ‘Kryptonite Transit FlexFrame-U Bracket Installation’ you’ll find a useful video. The principle of how the bracket holds on to the frame is quite simple, but if you approached the set of parts in the pack intuitively without accessing instructions or a video you might be a bit flummoxed. My lock is a ‘Kryptonite Kryptolok Standard Bicycle U-Lock’. By the time you’ve allowed space to lift the lock out of the bracket the choice of position within the bike frame is quite limited. I don’t mind that I don’t have space for a water bottle cage but if that is a concern you can fit it in various offset positions so that it sits outside the frame rather than within it
Review: Works Well - Easy to install and feels sturdy. Worked with my Kryptonite Series 2 lock (despite other reviewers saying it doesn’t). Probably a bit overpriced but ultimately doesn’t the job!

### ⭐⭐⭐⭐⭐ I got there in the end
*by O***L on 21 July 2021*

I needed a cheap solution to hold my old u-lock on the frame of the bike, since I didn't want to spend more than £50 on a foldable one with similar anti-theft quality. It took some DIY and imagination as you can see, but I got there in the end: - I had to cut off the rubber protection of the lock in order for it to fit on the larger of the 2 fittings. - by doing that, the fitting was a bit loose and it would swing with the pedalling, so I bought a cheap velcro holder on Decathlon (£2) and use it to hold everything tight. Sorted. Now I only have to wait for the old London tradition of seeing my bike stolen with malice and easiness and just give up and start walking everywhere (I hate public transportation).
