YOHOOLYO Alarm Disc Lock Motorcycle Disc Brake Lock Anti-Theft Waterproof 110 dB 7mm Pin 5ft Reminder Cable for Motorcycles Bike Scooter Carry Pouch Alarm Control Lock with Cable (LK8307)

After about two months I can say that this lock is magnificent. Works greatly, it is loud enough to scare whoever wish to try steal it and solid enough to be almost impossible for a thief. Together with a normal bike cable lock is the perfect combination to feel safe too leave your bike locked somewhere near or far. I really suggest this type because give you the option to set the alarm or not, which is useful if your bike is in a public place but also is not going to sound forever once active because of a bump.

Works great it does what it’s supposed to do

Just a heads up: when you open the package, there will be a lock and a bunch of batteries in the box. What they don’t tell you is there are also batteries IN the lock, so careful fiddling around with it unless you wanna test out the 110db indoors!Other than that… it’s okay. Don’t think it will stop a determined thief, but will slow them down. Alarm doesn’t seem to be too sensitive, so that’s good. Worth the price I’d say.

Fair price on a great item

Great piece we live in apt complex and someone tried to steal bike prior to having this and tore up the ignition. Now someone walks to close and slightly touched "or tried to mess with bike" the alarm went off immediately and loud. We heard all the way up in apartments and went down.

Love it

I love how loud it is. Also how sensitive it is. The area I live in people are always stealing bikes. This is a great deterrent.

Lock is of good quality and provides security with minimal work.
