Overview
The Fosmon 113dB bike alarm is a compact, wireless anti-theft alarm designed to help protect your bicycle, e-bike, scooter, motorcycle, cart, trailer and other valuables. It uses a loud 113dB siren and a built-in motion and vibration sensor to warn you when your vehicle is moved.
This alarm is controlled by a remote, so you can arm and disarm it easily. It is IP65 waterproof, making it suitable for outdoor use in rain and splashes.
Key features
- 113dB loud vibration alarm to deter theft
- Remote control operation for arming and disarming
- Motion and vibration sensor reacts when the vehicle is moved
- Adjustable 7-level sensitivity to suit different setups
- Three volume levels so you can choose how loud the alarm sounds

Installation and use
Setting up the Fosmon anti-theft vibration alarm is simple. First, choose a suitable mounting surface on your bike, scooter, motorcycle or other item and clean it. You can then attach the alarm using the supplied adhesive or use the cable ties and brackets on the back of the unit for a more secure fit.
Once installed, use the remote to arm the alarm. If the alarm detects vibration or movement, it will sound. You can adjust the sensitivity through seven levels to reduce false triggers or make it more responsive, and choose from three volume levels. The SOS function will detect an accident if the vehicle tilts more than 45° from its original position and will emit a beeping sound to attract attention.
The alarm can also be used as a luggage alarm, fence alarm, trailer alarm and for other items where extra security is needed, especially when combined with physical locks.
