“After a recent attempted theft of my bike, I needed to purchase a new disc lock. My previous old model Xena had given me piece of mind for several years but the would-be thief had managed to chisel off the alarm module before it had actually gone off. The sturdiness of the disc lock itself proved too much however, so they gave up before managing to move the bike away. (Please note newer Xena models have a more enclosed alarm system, so an attack on the alarm itself wouldn't be as simple)
Personally my bike is worth very little so I wanted to keep costs down for the replacement lock and this lock seemed to fit the bill. A very similar product to the Xena range but at about 1/3 the cost - but I wasn't expecting much
The JDC lock itself has a good to weight to it and feels nice and sturdy. The yellow colour looks nice and hazardous, so should catch your eye to remind you to take it off before setting off, and should also stand out to thieves. Now for the most important part - the alarm. Once you click the lock into place, it sets off a tone to let you know it's armed. After 15 seconds, any knock to it and it will tone a few times to warn you - loud enough to hear over most outside noises. Any disturbance after that and all hell breaks loose!!! Up close, this thing is deafening and its high-pitch warbling tone is really uncomfortable on the ear - after the first time I tried it, my ears were left ringing for a good few minutes. With it being as loud as it is, it must sap the batteries fairly quickly so it's a bonus that 2 extra sets are supplied with the lock (along with the allen key required for fitting)
Now obviously this item alone won't stop a determined bike thief. The only things that might are ground anchors, expensive toughened chains and complicated garage alarms. And there are obviously higher quality disc-lock alarms out there, but a skilled bike thief will have the wheel off the bike quicker than they can be caught, if all you are using is a disc-lock. So for what it is, this lock is ideal - the sensitivity is there, and the alarm is plenty loud enough to put off amateur/opportunist thieves and raise the attention of people nearby. It's also small enough to stuff in your jacket pocket.
For £25 this is a cracking piece of kit - buy one now. Or buy two, put one either side of your caliper to lock the wheel in place and as back-up. (I can only imagine how terrifying two of these would sound next to your ear)

“The unit seems to do the job well and actually fitted my bike disk well. Quite loud but not too sensitive to go off at the slightest breath of wind

“the alarm lock is a good deterrent for opportunist thieves though i suspect if someone really wanted my bike i wouldnt think it would be too hard to steal even with the alarm on however it works well and is a very compact but sturdy item try not to aloww water to penetrate around the keylock as it does start to corrode slightly a bit od wd40 usually does the trick though. i like this product and recommend it to others

“This seems to be quite a well made item - it feels fairly substantial - and it puts out a loud noise. Getting it with the spare batteries is a nice 'extra' convenience. I'm liking it, so; thankyou.

“Absolutely brilliant, got this a while back due to the fact I used to work at a place riddled with crime. No chance to get this lock off my bike that's for sure! Does the job absolutely perfectly, no chance of anybody getting the lock off without literally disassembling the entire bike! Recommended to everybody who wants the perfect disc brake lock!
