zerotop Bike Alarm with Tail Light, USB Rechargeable Anti-Theft Bicycle Alarm with Remote, 110dB Wireless Vibration Motion Sensor Motorcycle Alarm with Mount for Mountain Bike Electric Scooter Trailer

The media could not be loaded. This is the first anti theft alarm tail light I’ve purchased , honestly it’s the best, not the best , but it’s sooo good, it has a very loud alarm of about 110dB if not more, it’s volume can be adjusted as well. Once the lock is turned on from the remote any small push of the bicycle would trigger the alarm, it makes a beep first time as a warning, then once touched again, it beeps loudly again, then the third time it’s touched it makes a very loud sound that doesn’t stop at least not immediately until it’s unlocked using the remote, The auto break works well, the light changes as you ride ie if you stop or more, it either dims or shines brightly. In all this is just a very good product

Easy to fit, very bright light with 5 flashing programs and built in alarm with sound and sensitivity settings. Good price and works well

Very loud

Really impressed with this, great quality item at a great price!

Very good light and alarm.very loud

Works great

I love this. The alarm is enough to deter anyone in a built up area and the light function is the icing on the cake - especially as it’s auto/on/off.Battery life seems pretty good too. I ride daily and charge this weekly if that.

Have not fixed this to my bicycle as yet because my new bike arrives on Monday! But have set it up on my breakfast bar and tapped my breakfast bar and the alarm ⏰ goes off the alarm is very loud the reason I have purchased this is because my bicycle will be locked out side in my garden so if anyone tampere with my bicycle I will and all my neighbours will hear the alarm ⏰ going off! The 4 light features modes are great too cant wait to fit it to my bicycle
