Fosmon 113db Bike Alarm with Remote, Motion Sensor Bicycle SOS Alarm, IP65 Waterproof Anti Theft Alarm System, Wireless Siren for E-Bike, Motorcycle, Scooter, Cart, Trailer

Put this under the seat of my motorcycle. Works perfectly and is nice and loud. Comes with all batteries, so no need to wire it up to the bike's battery. Installed in minutes. Very happy with it.

Superb alarm. So good, i wanted another for one of my other bikes, but was concerned about frequncy clash between the two. I contacted the seller in the USA and they were very quick to respond and super helpful. I bought my second one and they bother work brilliantly. I thoroughly recommend these alarms.

I bought this for my wife's e-bike whilst touring Europe in our motorhome. The device is easy to fit but be sure to use both the double sided tape and zip ties to prevent it from easily being prised often and discarded. It's quite large so you may need to give some thought about where you locate it. Also you need to be sure you leave access to the screw for battery replacement. Otherwise you may have to cut it off and require fresh tape and zip ties to re-fit. Once fitted just remove the plastic battery isolating tab and it's ready to go. Setting is easy once you have read the included instruction sheet. The alarm is really loud!! It sounds a warning blast if accidentally nudged. Move it further and it delivers a continued blast of varying tones that attracts immediate attention. Of course it's not a substitute for a good lock, however if the bike is within earshot during a coffee stop I'm confident enough not to use a lock. I forgot I'd set it on one occasion and the warning blast even made me jump! So pleased with it I've just ordered a second one for my own bike. Only negative is the loop on the remote is made of thin plastic and has already snapped when attached to another key fob. Hence four stars otherwise it would have been five.

Nice & slim , easy set very load piece of mind . Fitted to a moblity scooter which is stored outside under a cover .

They are excellent and great value for money, I bought another two alarms.

Good item good to be safe, quite loud

very loud and sensitive

This is actualy pretty good, lifted seat up popped it with 2 x zip ties under seat, easy to alarm, with the fob, if bike moves alarm goes off exactly what it says on the tin, works perfectly, now for the downfall if its windy it sets it off if you have it under a tarp/cover, that said if it's in a garage shed ectthis is awesome

Only had it for two days. When tested it on my Fold 1 Plus it worked great. Mounted easily and was loud. Hope it will never have to be used. But I’m confident that it will work if needed. Good price and recommended.

Excelente producto

Fajny gadżet moim zdaniem bardzo dobrze wykonany, kupiłem coś podobnego na aliexpress i nie było to w jakość jak jest tutaj. Generalnie fajnie się sprawdza chociaż wiadomo, że nie jest zabezpieczeniem doskonałym ale odstrasza potencjalnego złodzieja i chyba dlatego został zrobiony. Sygnał głośny. Czujnik ruchu wrażliwy. Zapewne przyda się jako odstraszacz amatorów nieswoich rowerów

Liten smidigt alarm

Super alarmanlage fürs rad oder anderes geht laut und reagiert super.einfache bedienung und anleitung.manko das sie batteriebetriben wird.aber passt trotzdem.
