ONVIAN Upgraded Wireless Anti-Theft Motorcycle Bike Alarm Waterproof Bicycle Security Alarm Vibration Sensor with 2 Remotes, 113dB Loud

I use my ebike as a daily commuter to go grocery shopping and other errands. I try not to be away for more than an hour or so. I have an 11 pound chain lock but wanted to protect my bike accessories. I know you can't stop a real bike thief but I can deter an opportunist. I have this hidden out of site so no one knows its there. I am pretty sure this will scare the crap out someone. It is very loud and "should" draw attention. Its easy to operate and mine came with 2 key fobs. .

This is my second such device. This one has worked flawlessly and has a remote range of about 75 ft. Sensitivity is controlled via remote. I have a backup remote to bot. Highly recommend.

The media could not be loaded.  My storage room was robbed two weeks ago and talking to the neighbors guess it's been happening more often now with the craziness we all experience with some hitting even harder.Installed extra pad locks but still didn't feel safe becauze they can easily break it like before so this alarm system was the peace a mind I needed. I know it stop them but at least will startle them and alert the neighbors upstairs.Very easy to install just using the double sided tape included. Just clean the surface where you plan to tape it. It even tape very securely on wood surface. Also come with zip ties if you want it even more secure.The broken English manual that came with was a little hard to understand but with trial and error I figured it out how to set sensitivity and volume of the alarm. Trying to activate and sync the second remote need a little longer to figure it out but I eventually got the second one to work too.Do not throw the manual away because setting it in the future you will need it. Even I went through it I can't remember off my head how I did it without relying on looking at the manual. So they definately need a easier way to set it also better manual so average person not good with gadgets can figure it out quickly.But once it's set it works great. Distant from fremote to unit is pretty far. I walked outside th garage and was still able to arm and disarm the unit. Sensitivity is adjustable and I like how it gives you a initial warning if you trigger it. And within 10-15 second if you disturb the unit alarm will go off for 30 seconds and then off and rearm itself.Battery life will see how long will last so will update when I have to replace the unit battery or remote one.This is great for storage units, home, cars, bikes, motorcycles or anything else that will cause vibration if disturb that you want to be protected from.

This tiny thing saved my motorcycle so many times. Love it!

Solo un control funcionó

Burnt out a few weeks after I bought it, and then my bike was stolen. Don't buy. Get something better.

Worked fine until the temperature dropped to 30 degrees, when I activated it on my bike, it wouldn't stop beeping, so I crushed it open to flick out the battery's. None of that should have happened.

From start to finish the entire process was awesome. Received my items on time and confident that it was safe and secure once received by the hub location near me.

this thing is easy to mount to the bike.. u can hide it anywhere with zip ties..the sensitivity is pretty good.. gives u a warning when u first trip the sensor, then if u trip it again it goes nuts..

Worked as advertised. The second fob was not keyed in and had to find instructions to do this online (not hard). Overall operating instructions adequate but poor english.Overall happy with unit that I’ve attached to a basement storage cage to improve security.

Facile installation.Très "bruyant".Content de mon achat malgré le fait que la manette de rechange ne fonctionne pas même avec pile neuve allume mais aucun contact avec l'alarme.

The media could not be loaded.  The product wasn’t working and i tried opening it and found it was damaged

Le système d'attache consiste en 2 bouts de collant deux faces!?! Heureusement c'est le même boîtier que mon ancien système d'alarme alors j'ai pu utiliser mon propre système d'attache de loin plus commode et sécure! Les instructions en anglais seulement sont si difficiles à lire que pour l'instant j'ai abandonné l'idée d'activer la 2e télécommande.Dommage, ça aurait pu être un système très correct avec un système d'attache digne du nom et des instructions plus lisibles et en français. De très petites économies faites par le vendeur qui font que je ne recommande pas.
