Tchipie Motorcycle Alarm Disc Brake Lock, Theft Prevention Motorbike Security Wheel Disk Lock for 7mm Brake Rotor with 110db Alarm Sound with 1.5m/5ft Reminder Cable for Motorcycles Bicycles （Black）

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.

Easy to use and adds a great deal of security. Anyone wanting to steal this bike would have to do some major work to get this lock off. Thieves would probably choose an easier target.

Solid construction. Bright and noticeable. Very sensitive (I was unplugging my battery tender and only touched a wire on the other side of the Scout, and the alarm chirped at me). When I went to take it off a few seconds later, it alarmed. Good job. Not crazy loud, but enough to freak out whoever is touchy-touchy.I wish I had security video of when the neighbors cat jumped on the leather seat and hasn’t been back in the driveway since.

This lock attaches easily to either front or rear disc brake. The alarm is just right on sensitivity. It goes off after slight movement with a warning beep.The reminder cable actually services as a notice and warning of the lock.It is tricky to remove the lock with out setting off the alarm, as inserting the circular key is a challenge. It would help if the lock had a mark to show where the key notch inserts on the lock. I added one with a permanent marker.If the alarm goes off it is loud and piercing for 10 seconds. This should augment a secure cable lock in high risk areas. You can still lift and move the bike with the alarm, perhaps not fast enough to avert theft.

This probably won’t stop a pro but it was cheap and felt more secure when parking at shady motels

Good product

It does exactly what its meant to. I own two of these and was surprised to find out that the keys are actually unique to your lock. Comes with an extra set of batters and as far as waterproof the first night using it. There was HEAVY rainfall for hours and it still worked. I like that its black so it blends in well at night..If you're debating between a different disc brake or this one... Just get this one. compared to my 2 buddies that have a different brand this one is definitely better, hand down.warning 3 LOUD chirps, if disturbed again within 10 seconds or so a piecing alarm will blare.gives me enough time to look outside of my apartment window and take care of business. '/=== ~ ~ ~Update 3... lmao so I traveled overseas for a few days and when I came home the alarm didn’t work at all. The bike remains covered at all times so it didn’t get weather damaged even though it says it’s weather proof, I dropped it from 1 foot or less (from the rear caliper after unlocking) still worked after that but now it is only a lock... lol sad.

This product is a great convenient, compact and secure solution for locking up your bike which works much better than some other products which simply lock around the right handlebar grip and brake lever which doesn’t prevent someone from cutting the brake line and rolling off with your ride.“Thank you for a great product.” (I actually purchased two, one for each of my motorcycles.)

Unit works fine. Easy to use and compact for storage.

Indispensable : Faible coût Bonne fabrication et finition , parait très solide , fonctionne sans bavure (alarme sonore ) les piles durent Lourd dans le sac à dos

Antivol Alarme conforme à mes attentes, qui se place très facilement sur le disque de frein et se range dans n'importe quel endroit car il ne prend pas de place. Seul bémol, il est très sensible dès lors que l'on incère la clé pour ouvrir le bloque disque et désactiver l'alarme. Il lui faudrait une télécommande de désactivation. Il est également livré avec son cordon en acier et recouvert de plastique, d'une recharge de piles en plus ainsi que 3 doubles de clé et d'une housse de rangement.Sinon excellent rapport qualité/prix.

easy to use with a handy storage case for transportation whilst not in use, the reminder cable holds the disc lock in the vertical position under tension and stops the wind etc. from moving the lock resulting in warning beeps, the sensitivity is great it gave me warning beeps as it detected me putting the lock and chain on the rear wheel, the alarm is loud enough to move people on after it sounds, the warning beeps are great as this gives 10 seconds for someone to stop fiddling before the alarm goes off, great little lock well worth the money.

Kit completo con el antirrobo con pilas ya puestas, 1 juego extra se pilas, 3 llaves y el cable (en mi caso naranja).Confirmo las experiencias y opiniones que el resto de compradores de este producto: primer pitido de alarma y si se vuelve a mover, chilla muy alto por lo cual disuade bastante. No me aparece hipersensible al movimiento, me parece lo justo.
