Tchipie Disc Brake Lock Motorcycle Alarm with 110db Alarm Sound, Theft Prevention Security Wheel Disk Lock for 7mm Brake Rotor, Heavy Duty with 5 feet Reminder Cable for Motorcycles Bicycles

I got exactly a described product. The alarm is so loud. Great little device for any street motorcycle .

Loud alarm very easy to use key

Muy buen sonido de alarma

The alarm is very sensitive and can be annoying on a windy day when the bike is covered but overall very satisfied. I used it when living in an apt complex. It can be a deterrent for thieves because it will draw attention with the high pitched alarm.

I recently picked up a Honda Grom, and was concerned with the stories that I see on Facebook and the web concerning theft.The Grom has a wet weight of 229ish lbs and anyone that is semi-strong would be able to pick it up and throw it into the back of a truck or van. This is especially concerning to me as I live in an area where theft is common.I looked online for ways to secure my cute little pocket bike, and many people referred to this neat little device.It's a little lock that will latch onto your brake rotor, and will make it a lot more complicated to roll the little bike away. It also has a terrifyingly loud alarm and sensitive motion sensor.To be honest, I didn't know if this would be of much help, but to my surprise this little thing is quite beefy. It would take a noisy grinder or cutoff wheel to remove the damn thing, and even then I don't know if it would quite make it. Definitely a plus for that.I tried rolling the bike with this lock attached, and boy it's gnarly. If some thief actually did try rolling this while sitting on the bike they would be in for a sudden (and nasty) surprise.Price is affordable, and is a no brainer for anybody that is worried for their cute little thing. A determined thief will probably still be able to get away with the bike, but this will definitely make it harder. It also helped lower my insurance!The included strap definitely helps remind me to not move the bike until I unlatch it.

Easy to use

Spring for something higher quality. This alarm can be difficult get open, and rain triggers it to alarm. Most alarmingly, I was able to unlock with the key to another lock, which I used by accident.

I was parking my Harley in an open parking garage behind my car and was quite worried someone would mess with it. This will by no means stop someone from stealing it if they know what they are doing, but it someone decides to mess with your bike, any vibration will set this very loud, high pitched alarm ringing. It is quite a bit sensitive though as I found that on windy days my bike cover would set the alarm off. It will shut itself off after about 10 seconds though.
