Customer Reviews

Lightweight, Reliable and Safe
I've used this lock for a year and have had no problems at all with it. It's so convenient to not worry about keys, and if my friends need to borrow my bike I can just tell them the combo over the phone, so they're happy too. Just make sure it is long enough before you buy, because mine works on my commuter bike but is too short to accommodate both the front wheel and frame on my mountain bike. Oh, and DO remember to close the weather guard so if it rains the numbers don't get wet and slippery...that can be a minor annoyance.

Usable but not recommended
I found that the numbers are hard to change, they are not very smooth. Also it really is not long enough, I would recommend one that is longer, this one hardly fits around the frame and post at the same time.

Didn't work for me
I set the combo per instructions. Tested it 3 or 4 times to make sure it worked like I got it. Then a little later just before a ride I tried it one more time and it wouldn't open. One of the dials is really hard to turn, so maybe that's the cause. For some people it works fine, others it doesn't, so just know that you are taking a chance. I'm returning mine and going for a key lock.
