I have a Guard Dog U-Lock that came with that Jenson cable (or one that looks indentical, but says Guard Dog on it), I like it quite a bit. But it has some pros and cons.

First, it's great because it's strong. Secondly, it's large enough that when me and my girlfriend ride together, we can lock both our bikes with the one u-lock.

cons

It's heavy, secondly, it's large enough for two bikes to be Ulocked to a bike-rack. This seems like it gives too much leverage for a potential bike thief.


I would think that the smaller u-locks would be best to get rid of the added leverage.

The cable I wrap around the tires and through the rear fork then loop the ends on the u-lock. This keeps the Wheels locked with the bike, however I assume you recommend the pad lock for the cable so that there is a second lock the thief would have to break?

I would think that if they have the tools to brake the u-lock, they'd have a tool to brake the cable that you're using as well, which would seem to me that the pad-locks are a bit excessive.

I would assume that the more compact u-locks, with a decent cable to put through the wheels, would be plenty to deter 90% of the bike thieves out there.
