    Solid lock. I love the easy mounting system and the reliable strong links. I just bought a second one to put on my wife’s city bike.

    I’ve been using this lock on my daily commutes to lock up my bike at work. The lock unfolds into a long cable-like lock once expanded, but when folded is actually much smaller in size compared to a traditional U-Lock. The lock’s compact size, and light weight, makes it very easy to carry in my backpack. If you don’t want to carry it on you, the lock’s mount is easy to install on the bike and holds the lock steady. I recommend this lock to anyone who is a daily commuter and will have their bike out for a couple of hours. It’s tough, light, and compact. All the qualities a bike commuter wants from a lock! Get this for some peace of mind. Safe Ride!
