Tchipie 43121 Drilled Motorbike, Less 1/4 inch Red Alarm Disc 110dB Siren Anti Theft Waterproof Wheel Lock with 4ft Reminder Cable 3 Keys for Brake Rotor up to 7mm Thick Bike Motorcycle Honda Yamaha H

It’s a very good design vey loud and effective. Easy to use.

Next day to my door delivery. I think this is a great theft deterrent device. Built strong and well made (in China) The alarm is loud and annoying enough to deter an amateur. No one is going to roll my Harley Road Glide with the brake rotor locked to a better place to pick it up on a tow truck. They'll have to slide it around. I ride over 20k a year. This will give me a little more peace of mind.

I’m really impressed with the bang for buck on this lock. I don’t have a great locking solution in my car port so this alarm means I will hear it even two floors up if someone messes with the bike. It’s LOUD!Small bumps or anyone touching the bike will trigger the alarm quite easily. It unlocks easily and isn’t too much trouble to get on once you get the hang for it. I use it for an SV650

I like that it’s bright durable and easy to take off n put on

In the beginning when I was using this product I liked it a lot. It gives me the ease of mind when I park my motorcycle on the street but it has some issues in its features. Whenever it rains or there's very high wind it triggers the alarms mechanism which gets annoying. Luckily it doesn't rain as much where I live. After it rained a couple times the locking and unlocking mechanism with the key is not as smooth anymore. Before it used to be just twisting left and right, now it feels like it's jammed a bit so I have to put pressure to twist the mechanism. Overall it's a good product but if possible it needs it's kinks sorted out.
