Oxford Boss Alarmed Disc Lock

Just what I was looking for. Great piece of kit for an even greater price.

Big and chunky and 16mm shackle will be an effort to get through even with an angle grinder.
The alarm is not very loud at all. I doubt you would hear it from outside your house tbh.

External shell is plastic but it's relatively heavy so I assume must be substantial metal internally. Having set it off by accident it's not actually that loud.
The shackle is of sufficient size to go round most disks but doesn't come with reminder lanyard. Comes with 3 keys and it's very easy to use, batteries are not rechargeable so you will need to buy new button cells when they run out.
Overall it seems good value for the price.

It does the job. I'm usually using as a disc lock. Sometimes, it starts the alarm without reason or maybe a wind trigger the alarm. After few weeks of frost and rain I have discovered bit of rust on it, but it disappeared after cleaning.

This is an easy and convenient way to secure and alarm your bike both at home and away. Bright yellow so it stands out on the bike to deter thieves.
The lock is a large unit, if it will fit in your pocket you can defiantly feel the weight.
Sold secure Gold (!! really does reduce insurance !!), 3 keys and easy to use, Red to Red is armed, very loud alarm and auto resets after the alarm chirps, to disarm simply turn the shackle red to black.
The batteries are easy to replace by unlocking the shackle, unscrewing the battery tray and sliding the battery tray out, The batteries are said to last 6 months, time will tell.
I'm very happy with this purchase and would recommend.
Great Service from SportBikeShop as usual.

Great piece of kit for an even greater price. Yes it could be louder but it went off the other night and woke me and the mrs up. Usual quality Oxford gear and usual Sportsbikeshop prices.

Simply to use look's and feels strong, won't stop them stealing your bike ! But might put them off.

So far so good.

Easy to use, fits in my jacket pocket (just). The arming signal for the alarm is quite loud, but the actual alarm is less so. I'll be fitting new batteries to see if that helps. Can't comment on how it would stand up to attack as so far no-one's tried to nick my bike ( touch wood)

A simple to use lock that has no complicated switches, the clasp fits both ways red to red is activated the other way it isn't its that simple.
The lock is very big and heavy so make sure you have somewhere to store it when not in use.

good for RyanF9. good for me. I have one that i have had on constant use from 2009. outside.

It looks feels cheap, it difficult to use and the rain gets in. Their 16mm disc lock is a better buy, I can't see this lock lasting that long either. It's a big bulky lock as well & probably won't suit a lot of discs though it can be used with a chain.

Very chunky and loud. Easy to find somewhere to lock it to and easy to use and set the alarm.
