OnGuard BullDog Series U-Lock 3.5 x 5.5" Keyed Includes 4' Cable & Bracket

Seems nice and solid. Bike will not be left unattended for long periods of time but I still want it secure. It is easy to use and also not too heavy - that was important for me.;

I read someone's comment that said that the clamps that hold the lock on the bike is not made well. Nothing can be more far from the truth.

I should know because I have bought 4 of these ulocks. And after 5 accidents with my ulocks attached all of my locks have stayed in place.

People act like there is no such thing as an exception nor a faulty independent product;

Nothing will stop a determined and resourceful thief but this Bulldog will encourage him to move to the easier target. The quality is top-notch. I bought this for my son's bike. We live in a nice neighborhood (Greenwich CT) but nice bikes seem to attract bike thieves from the Bronx. After two years of use the bike is still in our possession while many located at the same bike-stand have gone missing. And for me that's a huge win. It's more than the value of the bike that is at stake for me. I don't want my son being a victim to scumbags and suffering that emotional toll. He'll get exposed to that later in life but while on my watch I want him to feel safe.;

I was pretty impressed I didn’t know how small this u lock is but it’s very strong and not in your way. AMAZING!!;

I like the fact they give you 4 keys with this lock as I like to keep a spare in another location. This also allows me to give access to at least two other people!;
