The Evolution Series U - Lock is your ultimate solution for top - notch bike security. Its secure disc - style cylinder is highly resistant to picking and drilling, keeping your bike safe from thieves. The short crossbar and shackle design create a compact fit, which not only offers better protection but also looks sleek. The hardened double deadbolt design provides extra defense against twist attacks. With a 13mm hardened steel shackle, this lock can withstand bolt cutters and leverage attacks. It comes with a Transit Flex Frame Bracket for easy transportation. This bracket fits on the adjustable spline and allows for multiple off - set fitments. You'll also get three stainless steel keys, including an LED - lighted key for convenience in the dark.


Using the Evolution Series U - Lock is easy. First, use the Transit Flex Frame Bracket to attach the lock to your bike frame. It's designed to fit well on the adjustable spline and can be set in different positions. When you need to lock your bike, insert the shackle through the bike frame and the object you're locking it to, then use one of the three keys (you have two standard 'I' keys and one LED - lighted key) to lock it. For the best results, make sure the lock is firmly in place. When it comes to maintenance, keep the lock dry. Moisture can cause rust, which might affect the lock's performance. If the lock gets dirty, you can clean it with a dry cloth. Avoid using harsh chemicals as they can damage the lock's surface. Also, remember to keep your keys in a safe place, especially the LED - lighted key as it's very useful in low - light situations.
