Motorcycle Lock Rechargeable, 120dB Alarm Disc Brake Locks Anti-Theft Security Wheel Disc Lock Waterproof with 5ft Reminder Cable and Carry Pouch for Motorbike Bike Scooter

Small and easy to carry. Very loud. Very sensitive, but heavy enough that the wind doesn't knock it and set it off. It gives two single warning beeps when moved/knocked, then 1 triple beep as a final warning. If you keep messing with it after that it screams extremely loudly until it is unlocked. Gives me peace of mind. Love that it is usb-c rechargeable. Highly recommended.

I bought this particular lock mainly because it is rechargeable, I own several high priced and high performance electric scooters, and the lock fits perfectly on the brake disc, which will prevent the wheels from spinning, the orange cord reaches the handlebar easily, but it's purpose is to remind you that the lock is in place, the alarm is loud and it will attract attention, everything about this product works as described, although the lock is small and compact, it's very sturdy and well built, but to have a peace of mind that your product is still there, always use some type of chain or U lock, a determined thief needs time to cut through everything to steal your bike, scooter or whatever, the alarm alone would be enough to make him change his mind, in fear of getting caught, they would just move on to something less secure. Nothing is really theft proof, it's all about the physical look of security that actually creates the deterrence, and two different types of locks is better than one. I highly recommend this particular alarm lock to anyone that's in need of a reliable disc lock.

Superb additional security item. Works great on my bike. Highly recommend.

Works good for my KTM 450 exc.Depending on where you are, it might not even be loud enough.

Simple n easy to use. Put it on my 2020 street glide. Fits right on the front disc I think it’s well worth the money for what this cost. Like any other security, just hoping they will hear the alarm and run away and not want to waste their time. When I was in my garage first time setting the alarm off, thought it wud be louder but I guess its fine. But then I thought if they set this one off, the Harley security on the bike will probably go off. That’s over 200 decibels. Seems pretty tough. I recommend it

I'm using this on the disc brake of a E-scooter with 10 inch wheels. It just BARELY fits in one spot thankfully but I gotta say the moment you engage this thing it instantly sets off the first warning... you got like a few seconds to have the strap ready and let go and be hands free on this...I worry about normal bumps that might happen when other people are using the same bike rack or fence or what ever you are chained up to if this will be an issue... Oh well better safe than sorry.(Paired this device with a 10mm thick chain bike lock from kryptonite - fingers crossed my scooter never gets stolen).

I would highly recommend these for E-bikes, It will slow random thiefs down just a few seconds and alert you with a siren. If you have scum around you, you need these. Best investment for the money. Use the included velcro pouch and keep it with you at all times. Remember to use the orange wire and attach it to the handlebar so you don't forget and attempt to ride away 😬

I purchased this over a month ago so I didn’t need to charge it until this week. Only to find that the charger they sent me was completely wrong for the device. It came in this little bag (shown in photo) and I had no way of charging it at first. I used my iPhone usb-c charger and it seemed to work for a bit. I went to use the lock again, it chirped like it was supposed to when locked. But after 3 days I went to test the lock out, when showing it to a friend. Only to see it wasn’t charged at all. I plugged it back into the USB-C and it’s not holding a charge. So the device seems like a dud to me. Disappointed really.
