Secondary Locks

Thanks @GA2G. That looks interesting I'll look into this and have a good read through the post by @clefty.

This forum is full of excellent information and advice.

Thanks again GA2G. I have read through the conversation started by Clefty and have a few concerns about the suitability of the lock but will probably get one or the Krabus. Whilst doing an internet search for the Xena lock I came across the following post which shows a broken Xena disc lock.

The poster lost a motorbike and there is little detail, however I imagine motorbike thieves go a little better prepared/equipped than the average bike thief given the value of the items. Still it's a little disconcerting.

Edscoble's comment about covering the sensor is also a little worrying with no lock to try on the bike. I imagine the Krabus and similar locks work in the same fashion and will have the same issue. Maybe an alarmed padlock would be better but do they have a similar sensor?

Looking at the Krabus disc lock on Amazon I read the questions; one query concerns the use of the item on bicycle discs to which someone has answered "dont know if it would fit bike .. wouldnt think it would be of much use anyway as bike could be lifted and carried away ". I assume this poster is poorly informed as wouldn't the shaking created during carrying set the alarm off.

I assume from your post (#134) that these are still the best option as far as alarms go.

Bar battery life I think I prefer the Krabus for the locks levels of sensitivity as opposed to the Xena's war on the ears for 10 seconds as a warning which seems to be the big complaint in the conversation started by Clefty.
