Mengshen Wireless Motorcycle Bicycle Alarm, Security Anti-Theft Alarm with Remote Control, IP55 Waterproof, 113 dB Super Loud (Black)

For a basic bike alarm it woks well, easy to install and loud alarm

Excellent product at good price

East to install.Could be louder but for the price a decent product

Very neat and easy to use. Great loud sound. Useful to keep my bicycle from being taken.

Very loud but 1. Put your palm on it and it gets muffled. 2. The arm and disarm beep is weak and cannot be heard from more than a short distance.I used to have a different bike alarm. Whenever I wanted to check on it's security I could hear the beep at the press of a button from over 150 feet away in heavy traffic and indoors.This has to be hidden otherwise it can be silenced. The problem is that hiding it inside a bike reduces it's volume and nobody takes any notice of alarms especially if they are not very loud.It may be best attached semi- externally but in a place a hand cannot reach so it sounds at full volume and cannot be easily removed.

What a brilliant alarm really loud. You can put it on any vehicle, soon as any vibration the alarm goes off. Brilliant. Such a good price as well.

Absolutely brilliant product in just one day it's done it's job instantly stopping unwanted interest of the vehicle in two locations just brilliant. Jj

This little beast is a must have for motorcycles or bicycle owners. It works very well.
