Sturdy lock

  • Familiarity: I've used it several times

Really sturdy lock. Can't tell if anyone's tried stealing my bike so far, but it seems like it'd be pretty hard to do. The rubber casing does a solid job of not scratching up my bike, while the included bike holster makes it easy to bring along without having to carry a heavy backpack.

A pretty sturdy lock

    So when my bike gotten stolen I wanted a pretty sturdy lock. This lock is perfect, if someone is going to steal your bike with this lock on, its going to be a lot of work them. It's easy to use and when your bike is locked up with this lock you feel more stress free.


    • Familiarity: I've used it several times

    This thing is quite large, ain't nobody cutting through this thing unless they had an acetylene torch. Not quite a good size to stuff in your belt or pants though when riding.

    Strong lock!

    • Familiarity: I've put it through the wringer

    I got this lock because so many of my friends have had bikes stolen at the grocery store by my house. Bike theft has become an epidemic and if we cant fix the problem, get this lock and make them think twice about stealing YOUR bike.

    For starters, the $2500 theft protection is a great comfort knowing they back and trust this lock. The Hexagonal structure makes it even harder to overcome this lock even if the thief gets it cut, they wont be able to turn the lock in the core due to it not being round. The anti-scratch coating is also nice because it does just that, not scratch up your sweet ride.

    So far I have had great luck with this lock. Knock on wood!

    It Is 14MM

    • Familiarity: I've used it several times

    When I got mine it was a 14MM instead of a 16MM.I called them and told them about this.They said they only ever had the 14MM in stock and that the Manufacturer said to list it as 16MM.Since Amazon sells a listed 14MM and is cheaper than this one, I was credited back the difference.Backcountry needs to change their website product info on this lock.As for the quality of this lock, I like it.I would have perferred the 16MM.I would have given it 5 stars but because of the product info snafu, I gave it 4 stars.

    $2500 theft replacement guarantee

      I like this lock. I feel it would be really hard to steal your bike if you were using this since the lock itself is a dual layer lock so you have to turn this key twice. It seemingly makes it hard to pick. Who cares though, they give it a $2500 theft replacement guarantee!!!
