Alarm Disc, Heavy Duty Anti-Theft Motorcycle Lock with 120db Alarm, Weather-Resistant, Powersport Disc Brake Lock

As Described Great product for price point. Adds piece of mind and security to my bikes. I have this lock on both of them. I like the audible alarm.

I’ve had this for a few months now and it’s been great. Because of its size that goes past the disc brakes, it’s quick to put on and take off which is what I wanted whenever I leave my bike anywhere. I didn’t want to fumble around trying to put it in through the little holes in the disc. It’s also pretty loud and sensitive at least for me. I’ve had no issues with the locking mechanism as others have mentioned but I also live in a dry area. Be careful not to lock it and throw it in your pocket.

It works as described. Easy to use. Does make a loud sound. Thanks for this very unique product for my ebike.

It’s a good lock. Feels sturdy and is somewhat compact for what it is. It’s not sensitive at all though. If someone tries to roll out or carry your bike or drops it, it will go off I’m almost certain. But if a drunk fool touches or sits on your bike then most probably it won’t go off. I guess this could be a plus or a minus depending what you are looking for, but for me personally, I’d rather have it a little more sensitive. I saw reviews complaining that it does not go off at all, I am suspecting they might not have activated it. When you lock it, it will either give a single beep, followed by another longer beep in a few seconds - that’s how you know that the alarm is active. If it beeps twice when you lock it then the alarm is not activated. I also wish it was a little bit louder, it’s not quiet but I think it could be louder.

My other kryptonite locks wouldn't work on my new bike but this fits right into the holes and is super quick to install. Just add a reminder cable to your order too.

Weight of lock is decent, feel confident with this lock! Definitely recommend!

Is very good

I feel much better using this lock than my alternative securement method. Hefty, solid & secure. Easy to use. Small enough to carry and not be cumbersome. Has an audible alarm (bonus) although I was unable to trigger it 🤷🏻‍♂️. I’m more interested in the locking mechanism and it satisfies my needs.

Splendid bit of kit

Perfetto per la vespa

Caro pero excelente calidad

Melhor trança de disco. Kryptonite diz tudo. Assim mais sendo sonora.

Very loud which is great and easy to put on and off .should come with a leed though.
