This very useful and practical Kryptonite Transit Flex Frame-U Lock Bracket is a highly adjustable bicycle mount designed to solve the age old problem of how to transport a U-lock without cluttering your backpack.
The Kryptonite U lock holder can be found at Amazon (affiliate link): amzn.to/4vYwYDG
It works by attaching a small, rotating clamp directly to your bike’s tubing, supporting locks with common 13mm and 16mm round shackles. Because it uses a heavy duty flexible strap system rather than rigid metal clamps, it can securely contour to almost any bicycle or stand up scooter frame shape, whether your tubes are round, oval, triangular, or square. It is compatible with tube thicknesses ranging from 25mm to 80mm, making it incredibly versatile across different bike styles, or traditional road frames to thicker tubed e-bikes. One of its most appreciated design features is the 360-degree rotation mechanism, which allows you to micro adjust the resting angle of your lock. This means you can tuck the lock away tightly against the seat tube or top tube so that it doesn't bump against your legs while you pedal. Once properly tightened, it is highly effective at keeping your lock snug and completely eliminating the annoying metallic rattling that usually comes with carrying a heavy duty lock on a bumpy commute. Additionally, the soft strap system ensures the mount stays tight on your frame without leaving permanent gouges or scratches on your bike's paint.
