Favoto Alarm Disc Lock, 3 Keys and 18 Batteries (5-Year Availability), 110 dB Waterproof Anti-Theft Security Brake Padlock, 7mm Lock Pin with Reminder Cable, Fit for Motorcycle E-Bike Bicycle Scooter

the lock is great and easy to use the alarm is loud and very sensitive and easy to trigger I only worry if someone walks by my motorcycle or just looks at it cause they think its cool it might still go off while im working and the batteries could drain but it Is great and performs well for the cost can't expect a $20 lock with an alarm to be flawless

I purchased this, not knowing how well it might work, or how well I'd like it. There are various vendors, selling similar looking disc locks. But going with the Favoto brand proved to be a good choice (more on that later).The alarm works well. It's easy to engage it with your brake rotor, whether you are attaching it through one of the larger or smaller holes. Works the same, either way. You DO need to have the key inserted, to arm/disarm it. Decide where on the rotor you want to put it, push the key in, and twist it, to SET the lock. Remove the key. It will then give off a brief chirp, letting you know it's ARMED. Further jostling of the lock, will set off a piercing, screeching sound. Those who say you can't hear it, might want to re-check their installation, or the batteries on their hearing aids :)It also comes with a complete set of spare batteries, which are ALREADY LOADED into another battery cannister, which you just swap out with the original cannister. A nice touch, so that customers don't have to fumble around, loading 6 small button batteries, and/or making sure each faces the same way.They also include a nice little nylon pouch to carry the alarm in, if carrying in your back pack, etc. There is also an orange, coiled cable included, with loops on each end. You can put one loop INSIDE your lock before closing it, then attach the other end to one of you handle bar ends, or nose of your bike seat, etc. The idea, is just to remind YOU that you have an ENGAGED alarm set, when you come back to your locked bike. If not, and you go MOVING your bike .... you will set off the alarm (which takes an INSERTED key, to disengage), and/or you might try to ride off, forgetting you have a small disc alarm attached to your rotor (creating possible brake damage). So the cable is actually a great idea.I had a small problem, and contacted Favoto about it. Molly quickly contacted me, asked some questions, and then she SOLVED the issue. It's really nice to buy from vendors, who CARE about their customers. If you are debating which vendor to buy from, I'd definitely choose Favoto.

A little tricky to close and lock without the alarm going off. Does work to make the bike secure and give you peace of mind.

Extremely loud and effective anybody that even bumps into your bike will set the alarm off and it sends people running highly recommend it at this to the Locking set that I get and my bike is pretty near impossible to steal nothing's impossible but this is as close as I can get and I am OCD paranoid so need this to say I bought a triple lock set and an alarm three different styles of locks to uncuttable Locks but my opinion all cables can get cut but you cut the cable you set off the alarm if you just move the bike even an inch it sets off the alarm highly recommend five stars all day long

It’s good to know that it doesn’t take much to get this lock’s attention. I hope it never has to go off, but if it does everyone around will definitely know it. It’s very easy to put on the disc. Good strong material. Very loud. I doubt many people could break this thick lock. Paired with a handlebar lock and hidden AirTag for added security.

Lock is robust and easy to put on/off. Alarm is nice and spare batteries :)

Funciona muy bien

Alarm not to loud. Wish the line is longer so I can attach it to the handlebar
