ONVIAN Motorcycle Disc Brake Lock with 120dB Alarm, Rechargeable Waterproof Motorcycle Locks Anti Theft for 7mm Motorcycle Brake Helmet Scooter Wheel Lock 5FT Reminder Cable (Lemon Yellow)

It seems like a good lock so far, fits the rotor of my 2017 Harley Davidson Ultra Classic perfectly. I’m not sure it’s charging, when I plugged it in to make sure it was fully charged the light never illuminated but when I installed and tested it it sounded its alarm. So far I’m very happy with. Locking mechanism is smooth and crisp feeling, no problems with key.

This alarm is super loud and does its job really well. I like that you can also set it to silent mode so it won’t alarm at all. Sensitivity feels just right — small wind gusts won’t trigger it, which is great. As for the reminder cord, instead of using a traditional hoop to attach it, it uses a small metal ball that's just a bit bigger than the gap. It's a clever idea, but honestly, I prefer the hoop style. Not a big deal though — overall, pretty happy with it.

Funciona bien!

It's great need to only charge every few months

This is a great idea as a wheel lock as a whole the alarm itself though is extremely sensitive to motion. The slightest movement of the bike or the lock device will activate the alarm. Even my dog tail hit the alarm causing it to sound. Otherwise this is pretty cool device.

Great little security alarm to have. Its quite loud! We used these on our dirtbike's disc brakes for a long road trip. No issues and stayed charged for the 8 days. Highly recommended to deter theft when having bikes in the back of trucks. Something to deter a thief.

Good product works well for the price

Perfect
