Protect and deter theft with Fosmon’s 113dB Bicycle Alarm. This alarm works great to provide additional security for bicycles, motorcycles, e-bikes, scooters, carts, trailers, and other expensive equipment.
This device can be used for more than just being a bicycle alarm. With IP65 water resistance and the ability to be mounted with adhesives or cable ties, you can use this device almost anywhere. Increase security by using this as a luggage alarm, trailer alarm, fence alarm, window alarm, and more.
Control the sensitivity of your vibration sensor alarm with 7 levels of adjustment. The alarm sound can also be set to 3 different volume levels. You are able to pair up to 8 remotes with one alarm, or use one remote to control multiple alarms.
Clean and dry the desired mounting surface. Then, apply adhesive on the back of alarm and place on desired surface, or thread cable ties through brackets on back of alarm and tie around the desired item. After the alarm has been mounted, use the remote to arm and disarm accordingly.
This bike alarm responds to vibration and being moved. When nudged, a small beep will sound, and when it is moved the alarm will trigger for 30 seconds or until stopped. With SOS enabled, the alarm will automatically make a beeping sound when your vehicle falls over due to accidents.

I bought this for my Scooter and it works great. Sensitive enough to beep a warning while I put a tarp on and loud alarm if I moved my scooter. Small, lightweight, and easy to put on. Comes with batteries, zip tie, and double sided tape. Very happy with it and I loved the advertisement for it. Made me laugh!

So I bought these for going on an overseas trip. They worked great for that. I bought 3.1 for the door and 2 for something else. I won't go into detail on that here. I only ended up using one on the door, and it worked great. The things are loud as hell. I had 2 programmed to 1 remote and 1 on it's own.An unforeseen use came up at home as well. My dog loves to get into the blinds to look outside. I was worried she would mess them up. So I programmed them all to 1 remote and put them on the windowsills when I'm at work. Now she won't touch them!You can change how sensitive or how loud it is. I didn't find the need for any of that though. If you need some type of motion (vibration) sensing alarm, this is a great option.

I recently added this remote-controlled alarm to my electric scooter, and I couldn’t be happier with the results. As someone who relies on my scooter for daily transportation, I’m always concerned about theft, especially when locking it up at a bike rack in public. This alarm has given me so much peace of mind.Durable and Well-BuiltThe alarm feels solid and well-made. It’s compact enough to stay out of sight, but the quality of the build gives me confidence that it can withstand daily use and varying weather conditions.Powerful AlarmThe sound is LOUD—exactly what you want in an alarm. If someone so much as nudges the scooter, it triggers a piercing alert that would scare off any would-be thief and draw immediate attention.Easy InstallationThe installation process was straightforward. It comes with everything you need to attach it securely, and the instructions were clear. I had it set up in less than 10 minutes.Convenient Remote ControlThe remote control is a game changer. It’s small enough to carry on my keychain and has a good range, so I can activate or deactivate the alarm without having to be right next to the scooter. The remote also feels sturdy and well-designed.Added Security LayerWhile I always lock up my scooter with a quality U-lock, this alarm adds a crucial extra layer of security. Knowing that any tampering will trigger a loud alarm makes me feel much more comfortable leaving my scooter unattended for extended periods. It’s a deterrent that could make a potential thief think twice.Battery LifeThe battery life has been excellent so far. I’ve been using it for a few weeks, I appreciate that it doesn’t drain quickly despite being in constant use.OverallThis remote-controlled alarm has become an essential part of my scooter setup. It’s affordable, easy to use, and provides an extra layer of protection that every electric scooter owner should have. If you’re looking for a reliable, effective way to deter theft, this is it. Highly recommend!

Easy to install and use. I would like the alarm to be a litle louder, but the sensitivity is good!

I bought this alarm for a newly purchased ride on tractor mower to determine thieves! My neighborhood has been having lots of thefts. Last year I had a walk behind mower stolen and they actually tried to break in my house! I now have a security system with cameras yet this will add extra security for the mower!The volume is definitely loud enough to scare off any theft attempts and I can hear it inside my home!

Fits okay. Sticks okay. The noise is extremely LOUD!!! It literally detects vibrations with great quality and performance. If it sticked better it'd be the best to preventing theft.

When I received it it didn't work I don't know if it was the battery what was dead or just a speaker wasn't connected correctly but after I took it apart and screwed with the internals a little bit I got to work a little bit better update from the first rating I did for this product

Die Alarmanlage ist recht laut. Ich kann mir vorstellen dass das einen potenziellen Dieb vom stehlen abhält. Ich würde sie wieder kaufen.

Great value little alarm that is easily customisable for purpose.7 sensitivity settings3 choice of tonesVolume is customisableWhen armed, gives two brief different tonal warnings intervals apart before it wreaks havoc (continuous).Also has finder button to locate item.For $23-28, despite the crisp plasticky look and feel of the remote, this little wonder has become a necessity as an effective deterrent to bike theft as bike locks are all eventually overcome with the right tools. So nobody's complaining. Thankyou!Trick is to find a spot to hide/ secure it so that it is hard to remove too easily.

This is an awesome little alarm. I put it on my motorcycle for a little extra security when I walk away from it. If someone just bumps the bike a little bit, it gives a warning signal, and if they touch it again, then it goes off in an alarm form. It has a good little clicker that you can use to lock your bike as you walk away from it and unlock it as you walk up to it. Everything about this is actually a lot better quality than I expected. I think it’s totally worth it. Great for $23 bucks!
