Customer Reviews

yeah, this is disappointing
first: always know that a cable lock is not meant to be your primary lock if you lock up in an area where bikes are ever stolen. ever.

the doberman was intended to be a back-up lock, locking my front wheel to my frame with an OnGuard u-lock locking the rear wheel and frame to the fence or post or whatever. however, today my OnGuard u-lock failed me (bent 3 keys in the lock trying to lock it when i got home from work before giving up on the lock altogether-- i have two working keys left, but don't trust them-- there is nothing saying they won't bend and fail also, and i'm glad i discovered the problem when i was at home where i could get to my extra keys. glad i still had them. now i know why they're included). i brought my bike inside instead of locking it to the fence as i normally do.

ten minutes after getting home, i realized i needed to take a quick trip to the office supply store, so i went back out, this time w/ this OnGuard cable (no keys necessary! yay!) and an old kryptonite u-lock i borrowed from a friend. there was no fence-- just a post to which i could lock either the front end of the bike or the rear end. it's not a fancy bike, not the most attractive or theft-inviting thing on the street, so i locked the front end with the kryptonite, figuring that if i was quick, the cable would be enough of a deterrent to keep anyone from messing with the rear wheel while i picked up my supplies. i was in the office supply store for no more than 20 minutes, but when i came out, guess whose combination cable lock was smashed and whose rear wheel was missing? guess who was stranded at the office supply store for nearly 2 hours while she waited for a friend with a car to come pick her and her frame up? guess who was incredibly irritated for the rest of the night and probably will continue to be irritated until she can replace the missing wheel?

a passing tow truck driver stopped and told me how people break these locks-- it's depressingly simple (basically a pull and a kick, and the teeth in the combination shatter like candy).

don't get this lock unless you live in a low-theft, low-vandalism area. and even then, i'd think twice.

I should have bought a Kryptonite
When the cable is open, in order to plug the ends together the dials must be set to the combination. This is typical for locks of this type. However, the combination dials on this lock rotate far too easily.

Thus, when locking the bike, any slight contact with something else moves the combination dials and then you can't insert the other end of the cable until you set the dials again.

The same applies after unlocking the bike and you are recoiling the lock to stow it away. If anything slightly touches the dials, you have to set the combination dials again so that you can insert the other end of the cable.

My old Kryptonite combination dials had more friction in them and this never happened.

Use this and get your bike STOLEN
This product will NOT stop your bike from being stolen. My bike was
stolen using this lock in broad daylight in a high traffic area of San
Francisco. This lock will only stop a person with no tools. Bolt
cutters go through this lock like a hot knife through butter. It won't slow
a theif down more than 2 seconds.
