    Locks are great

    These locks are very high quality and make me sleep easy at night knowing that my bike will not be stolen.

    kryptonite keeper standard u-lock

    The lock rattles a lot when used in the mount, so I have been carrying it in my backpack which is less convenient than I had hoped for, but I think I can figure out a way to rig it so it won't rattle. I wouldn't expect this single lock to secure my bike, but it does work well as a second lock. Kryptonite was very easy to reach when I needed help registering for the anti-theft protection, which I was very grateful for.
