The Lock: The lock is what you would expect from Kryptonite. It is compact, well-protected by its rubbery coat, and smooth to operate. It still has some heft to it (don't expect it to be feather-light), and fits in my back jean pocket easily. It comes with a mount that I never bothered to install. Like other reviewers have stated, the mount comes with incomprehensible installation instructions (this is why I knocked a star off, otherwise I would have given full stars).
Using The Lock: I also purchased a locking skewer (from Pinhead) for my front wheel so that I wouldn't have to carry a cable at all. With your front wheel secure, you only have to lock up the back wheel. When I had originally purchased the lock, I was afraid that I would find myself unable to lock my bike to larger poles and what not due to the small size of the U. However, over months of use this has NEVER happened. Perhaps this is because I am fortunate enough to live in a rather bike-friendly area with lots of actual bike racks. However, even when a legit bike rack was not available, I have always found something that I could lock to. Thinner to medium-sized street poles or stair rails have always worked. If you live in an area where huge poles are the only solution to lock your bike to, this lock will not be for you.
I have had this lock for over four months now, with no theft.
Bottom Line: This is a great, secure lock for people who do not want to lug around a huge lock.Read more ›
Mounting help: To install this mount securely you need two people, period. Be sure the nylon band is threaded through the mounting bracket so that the bracket pinches the band between the bike and bracket when the lock mount is screwed into the bracket. Use your assistant to keep the band very taught while you screw the lock mount into the bracket. This undocumented mounting process results in an extremely secure mount that can be placed in many frame and seat post locations. Be sure to note that the mounting clip on the lock itself can be swiveled 360 degrees for proper positioning of the lock almost anywhere on your bike.
Addendum 6/1/2014: While this lock is too small to fit around a wheel, frame and most bike racks, it will usually fit around a wheel and most racks, at least with my 28mm tires. The advice I have read recommends threading the lock through the section of the rear wheel within the triangle formed by the seat tube and the rear hub stays. The thief would have to destroy the rear wheel or cut the lock to get the bike, and they usually don't bother. Unless you take the front wheel with you (or carry dual locks), it is vulnerable, but also cheaper to replace than the bike.
The mount that comes with this is also very nice, and doesn't move at all once properly installed. Ignore the manual and instead go to YouTube and watch their installation video: https://www.youtube.com/watch?v=QqaqSG-lfGo. If the link is dead search for "Kryptonite Transit FlexFrame-U Bracket". It's much easier to understand.
As for the theft insurance, make sure you register for it within 14 days of purchase or they may try to deny your claim. It's in the fine print, and not obvious that you have such a deadline.
Within 4 months of owning the lock, the internal mechanisms have rusted out and my key no longer unlocks the lock. I was very disappointed at how easily the lock succumbed to the elements.
I'm not sure if there are any better alternatives, but this lock was not worth 50 bucks.
Update: I have owned this lock for a while now and thought I should update this review. Apparently, most people experience lock jam if left outside. I give this an extra star because it isn't too hard to restore some functionality back. Simply soak the lock in some vinegar and rinse out. Bake it on low oven setting (low as possible) until dry and then apply lube (teflon lube is great for this although any will do) to the keyhole. This should make the jam a bit more manageable although it does not fix it completely (requires several attempts before opening still).
