Comments

Daniel Reardon: The bolt lock itself is your pre-emptive security. Do not rely on the cable if you want to secure your property. Hand-held bolt cutters can cut through that cable in the blink of an eye.

Donatella: Mi piace. E’ solido e ben fatto. La corda poteva essere più lunga ed è vero è pesante (io lo tengo nel bauletto)ma se si vuole un minimo di sicurezza…. Poi è fortuna si sà!

Gjolaj Florjan: Sturdy lock but cheap clip you can attach to your bike to hold the lock while riding. But for this price, i think this is fantastic quality since the main lock is what you buy it for.

comes with 4 keys and 1 with a light, really fantastic quality. Definitely recommend it

Al Cappuccino: For the quality price is quite great. Been using for my bike to leave it the whole day at the station. Can only be cut with a power tool. I think it is also light for the security it provides.

SchnitzSchnitz: I really like this lock. It feels really beefy and is big enough to get around my bike frame and the bike rack. Also, like the cable so I can loop through my wheel. When I first got the lock, it seemed to big to mount anywhere on my bike, so I was kind of bummed, but then I read the instructions, and saw that it could be mounted on the seat stem. I was skeptical at first, thinking it would interfere with my pedaling, but after I installed it, I didn't even notice it. So that's a plus!
I've only had two issues.

(1) Sometimes it's difficult to get the base locked onto the 'U'. I did lube the lock with white lithium lube so I know its not jamming as the key turns easily. So I'll live with it.

(2) The lock clip that attached to the my bike came unscrewed when I was mountain biking. I know it was tightened when I installed, but I guess all the bouncing down the mountain caused the screw to back out and the lock to fall off. I have since reattached and put some loc-tite on the threads. Hopefully this will hold.

Michelle S: So far, this lock has done its job. I live in an area with moderate bike-crime and commute to an area with almost none. My garage is secure, but if I'm shopping near home, I want a big scary lock that'll make my bike seem significantly less attractive to a thief than the flimsy cable-locked bike next to me.

This is that lock.

At the end of the day, a bike thief with the right tools can break any lock and definitely any cable, unless you're willing to invest in and slug around professional grade steel chains. I'm not. I just want my bike to look less easy to steal and this lock does the trick.

I have a strangely shaped bike, so it doesn't quite get around either of my tires and the frame, so I boot each tire to the frame with mini-u-locks, run the cable from this between them and onto this u, and secure this u to whatever I'm tying up to. There's an approximately 4" diameter water pipe at work that I lock to, and the round part of this lock fits around it no problem. The construction seems very secure and the insurance scheme, while a royal pain to fill out and send in, seems legitimate.

My bike is my exclusive means of transportation,...
