Would buy again but don’t think I’ll have to for a long time!

Abby BrownDecember 4, 2025

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. Read more

GREAT $20 ANTI THEFT DETERRENT, amazing value!!

Rick O.December 31, 2025

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! Read more

Great Value Disc Lock with Loud Alarm and Useful Reminder Cable

NicheSeptember 16, 2025

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. Read more

Simple and Effective

SassySpaceDragonSeptember 1, 2023

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. Read more

Works for my 2003 CBR600RR, but it did not fit the front tire on my 2023 Ninja 400.

John LinOctober 27, 2025

The media could not be loaded. 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. Read more

A year and a half later and still rocks

Chris GarciaNovember 10, 2025

After a year and a half of use, after many drops on solid concrete, after all the rainy and cold and hot days outside and in the garage, I still haven’t had to replace the original batteries. The alarm chime is loud and works perfectly every time but isn’t so sensitive that it activates when the wind is too strong. I’ve forgotten to remove the lock before attempting to ride away and it stopped me dead in my tracks, and has been just as reliable and functional since. No problems whatsoever with the barrel-type lock, even though I use this about 4-5 times a week. I’d absolutely buy this again but I don’t think I’ll need to for at least another few years.
