Oxford Boss Alarmed Disc Lock

Good lock very sensitive alarm.

I purchased this lock as its sold secure and recognised as a high security lock by my insurer. The lock is very big and heavy with a half moon shaped key way. It's coupled with a chain and the bike is secured to a ground anchor. It can also be used as a disc lock but the shackle is very thick and won't fit all discs. The alarm is not very loud but should help to deter opportunistic thieves. All in all, I'm pleased with my purchase and would recommend the Oxford boss lock.

Great product for the price
Goes off if the bike is shaken
Easy to carry ideal for putting under the seat of the bike

I like how this is versatile and can be used with a chain or disc. Easy to use but the key could be a little tricky for some as it has a half circle design and can only be inserted into the lock in one way.

Fits snugly on rear wheel of Ninga nx1000, in a position difficult to get a grinder in, not loud, but enough to hopefully make them choose another target

A good quality lock that fits easily into top case when I am travelling. I also use a highly visible yellow cable from the lock to my handlebar so I don't ride off when the lock is on and it might be an extra deterrent to a thief who may go elsewhere.. As always, good and prompt service from Sportsbikeshop

Water pours into the body through the shackle so goodness knows how long this will last.

Just about fits through the discs on my g310gs, wouldn't go any bigger.

As others have said though the alarm could be louder and it is a little too sensitive - it goes off too easily when I'm trying to unlock it.

Great product, feels sturdy, and loud enough for most needs

Seems well made and easy to use but the alarm is a bit quiet when outside. Not sure how many passers by would pay it any attention. Like how easy it is to lock it without the alarm activated just by placing the hasp in the other way round.

Quality, Robust lock that works well. Alarm sensitive, loud and effective. Excellent value, great price from sportsbikeshop too.

Super strong and sturdy lock. The alarm itself is switchable i.e. it's not always on, you've got the option to secure the lock without the alarm.

The alarm itself though is pretty weak. Not sure where the 100db comes from.

Appears high quality and tough. Great visible deterrent, the large size and bright colour helps with this. This also gives it a downside in that it's heavy and a bit awkward to carry. Overall though it's a great product and I'm very pleased with it.

This is a replacement as my old one (over 12 years) is not so sensitive and pretty battered now.
The new lock is very sensitive and is very solid. I use it with an Oxford chain.
A great lock.

Just bought this ready for a trip to France on the GS. A very robust all be it heavy unit. The alarm is good & seems loud enough, it is quite sensitive but certainly won't flap around in the wind due to its weight. I am happy with it thus far.
