110dB Alarm Disc Brake Lock + Free Carry Pouch and 1.5M Reminder Cable Anti-Theft Motorcycle Motorbike Security Lock

very loud, easy to use, packs away nice and tidy, fantastic value

Bought for my e bike. I considered a couple of "known brand" alternatives at 2 or 3 times the price first but decided to take a punt on this one. Very pleased that I did, time will tell, but so far works perfectly. Bearing in mind that any bike lock is only a deterrent at best, this is just as likely to make a prospective thief move onto another bike as a more expensive version. It is a bit fiddly to get both the reminder cord and lock into the pouch, but doable with patience. Highly recommended!

Used daily and so easy to use , quality is good, works well and alarm is loud enough for its size .Use it with other security products as part of a multi layered approach, making it more of a deterrent for thieves.Comes with spare batteries and a case , easy to put in jacket pocket or under the seat .

Arrived in nice retail packaging with the free springy reminder cord and spare battery pack as well as a black nylon case to store the Alarm/lock and small Allen Key to open up the lock to change the batteries.Then alarm/lock is simple to use, you just push the button to lock the alarm/lock onto one of the holes on your wheel’s brake disk and that automatically activates the alarm. You get 10-15 seconds before the alarm fully activates, so you can fiddle with it to place it in its optimal position. Once the alarm is fully activated, if it’s moved or tampered with, the alarm beeps a few times as a warning and then stops. If it’s tampered with again within a few seconds, it fully activates and sounds the full 120 decibel alarm. To stop the alarm, you simply use one of the 2 provided unique keys to release the button and remove the lock to stop the alarm. If the alarm isn’t activated and you want to remove the lock, you just unlock it with the key and because you have the few warning seconds, all you will hear if you accidentally move the lock whilst unlocking it, is the beeps. If you use the provided bright yellow spring reminder, you simply place one end in the lock before locking it onto the wheel and the other end stretched onto one of your handle bars. That way, you clearly display that your bike is alarmed and locked, it’s a reminder for you not to try to drive off with the lock on the wheel, thus potentially damaging your bike and it also acts as a tensioning device on the alarm/lock, stopping it from moving or rattling around in (very) strong winds, and also holds the wheel in place if it’s off the ground, stopping it from turning.I have an alarm on my scooter/moped but only use it places where I cannot chain the bike securely, saving the battery when not using the bike in long periods, so this alarm lock is the ideal way to lock the bike and also have a visual and audible deterrent stopping anyone tampering with my bike. I love it!

Well to start with this thing survived flying out of my rucksack onto tarmac at 40mph and still works so it's durable. Does exactly what it says. Alarm auto sets and is loud enough to get your attention. Not had to change the batteries yet and had it a few months so battery life is good.As for security if the thieves want it they'll take it regardless however I think they'll end up with a bad headache and people noticing them. So the security isn't bad.

Great price, good size, nice design, easy to use, build quality seems ok and it's loud, but alarm is just far too sensitve. Batteries are easy to remove & replace and it comes with spares. But........Is that my bike getting stolen?No it just the rain, a car driving by, a loud noise, slight vibration or just somebody farting from 10 meters away.If there was a way to adjust the sensitivity this would get 5 stars.For the number of times it has woken me and neighbours for false alarms it should only get 1.

Compact sturdy disc lock with case, easy to carry on my bike

All good..Does exactly as it should.
