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

Excellent lock, very secure and easy to use Review: This lock exceeded my expectations. It is sturdy, easy to install, and the alarm is very loud, which is perfect for deterring any theft attempts. The materials feel high-quality and the mechanism works smoothly. I've been using it daily and have had no issues so far. Great value for the price. Highly recommended for keeping your motorcycle safe!

Solid lock to keep the looky loos and honest people out. Doubt it will hold up to professional thieves, I use a couple of Kryptonite U-Locks through the wheels and brake/sprocket for overnight storage. But if you're looking for something to keep people from rolling away/stealing your bike while you're in a store or bar for a bit, this is a good option. The alarm is really loud and will activate if someone tried to tip or roll your bike. I like the bright chord because it draws attention to the fact that it's locked. It packs easily in my KLX300 Dualsport stock rear fender bag.

I've owned and used this lock for an entire riding season. Its batteries have lasted that long, and have shown no indication of running out. It's small but heavy, and my god is it sensitive. Maybe that's the only thing I dislike about it is how oversensitive it can be- if I know it'll rain, I'll make sure to put it on the back wheel instead of the front wheel, because if the rain hits it, it will go off. It's been very sturdy, and I find I don't use the cable it comes with. It's so sensitive that if you even start opening up the tail bag casually instead of carefully, it'll beep at you. I live in an area where there are people around all the time, so I use it as more of a 'pay attention to me, I'm getting stolen!!' alarm than an actual theft deterrent. When I sleep, I leave my window cracked open. If anyone touches the bike, even the neighbor's cat, it'll chirp and I'll know to listen to see if it goes into full scream-mode. The alarm itself is pretty loud and piercing. It does hurt my ears up close, and it's *very* noticeable even several hundred feet away. (Definitely wakes me up at night when it rains and I forget to move it to the sheltered brake rotor on the back wheel!) Pros: -small, easy to store -very durable -loud -battery lasts long -water and weather resistant/proof -direction of unlocking twist (clockwise) means that if you mount it right, it's easier to unlock without going off Cons: -Can be oversensitive -Goes off in the rain -lock mechanism is beginning to get a bit stiff after one year of weather-induced neglect Would I buy it again? Oh yeah, it's perfect for my use-case scenario.

This is a great-priced disc lock for motorcycles or scooters. It’s easy to use, locks securely, and comes with a loud 110 dB alarm that goes off if the bike is moved — a great deterrent. The set also includes an extra battery and a bright reminder cable (like a plastic rope), so you don’t forget the lock is on your disc. The key is simple and works smoothly, though it might not be the most high-security key design. It’s possible it could be easier to duplicate than more advanced locks, so I wouldn’t rely on it as your only layer of protection. That said, for the price, it’s an excellent secondary lock to have. Compact, waterproof, and comes with a carry pouch — definitely worth it for peace of mind.

Very loud, works great, easy to use, and very sensitive which I appreciate as people often try to take my motorcycle cover and this is sensitive enough that it goes off if you’re rough with the cover as I thread the reminder cable in it. Have had it for 6 months and dropped it a few times and it works great. It’s also very discrete and looks well made.

Works exactly like intended, and I've already caught and stopped 2 people trying to run off with my new ebike

Loud enough. Very heavy duty. The whole package- the lock, orange steel braided cable, pouch, EXTRA SET OF BATTERIES, packaging and the simple instruction sheet = THE BEST DEAL AT ONLY $20 SHIPPED! I LOVE AMAZON PRIME! I just wish I would have bought into some Amazon stocks shares when Amazon first started up!

Works for my 2003 CBR600RR, but it did not fit the front tire on my 2023 Ninja 400. Make sure that you check the pinhole size of the rotors that you have before you buy. For my 2023 Ninja 400, I had to get a smaller 5mm lock for the front. This 7mm one would only fit the back wheel on my Ninja. This can fit on both wheels of my CBR however. Alarm is loud and not overly sensitive, which is good. However, if its already agitated then it will get more sensitive and then make the alarm sound, which is quite loud, louder than the video depicts. Overall good, but I haven't tested the lock strength yet and I don't plan to. Don't rely on this to fully protect your bike though. If a thief really wants your bike, they can still lift it. This just prevents them from rolling it away. I still think that a solid hit with a sledgehammer could still break this lock.
