Onvian115dB Bike Alarm with Remote, Bicycle Anti Theft Alarm Vibration Motion Sensor System, Rechargeable Bike Alarms for Ebikes/Motorcycle/Scooter/Car, IPX5 Waterproof

This alarm works great as an alarm, but the bell is really loud and scares people when you use it. I got a little ding ding bell for when I’m riding on walk/bike paths.

This is a very nice alarm for your electric scooter, bicycle or whatever type of personal vehicle you have.You will need a pouch or some type of container whether that be a pouch, container or bag to place it in, since it does not necessarily have any type of magnetic function to it. Otherwise, great for the price and the remote is easy to understand.Had mine for nearly a week now, works great. Only problem is it's easy to remove once located on the vehicle, so I would recommend getting maybe a pouch with some type of padlock on it in order to make it harder to take.

This alarm is LOUD! Should scare off amateur curious kids or thieves if they touch your bike. Easy to install with zip ties. Added rubber under remote holder mounted on the handlebar to keep it from moving and that worked well. So far, no problems.

This is one of two alarms that I have purchased of this particular design and features. This latest design is definitely an upgrade. The one I have had previously did not come with a USB port for recharging the unit. That is a great improvement. Also the new one (this unit)comes with a few more customized settings*custom alarm ringtones/and remaining charge gauge,etc.. make it a great value. Sensitivity is factory set so theres little to do after you install it where you want. The mounting options are included with zip ties, double sided 3M. It is small enough to mount discreetly and the sound it emits is comparable with some auto alarms. Its water resistant. I only have one less than perfect issue with this unit. ( The instructions are very insistent about using the enclosed USB charging cable/included with the unit). Ok , that's fine if its unique in its power transfer or the harness is unique in the porting,etc. However, their cable DIDN'T WORK. not to worry though,ANY "C" class USB will work great. That being said,its not a big deal for all the other things that it does. And you can sleep easy knowing its going to work and as long as you occasionally charge it or perhaps plug it in to a dedicated USB port that comes on with the vehicle you have it protecting..then you won't have to worry about that either.

This alarm definitely has a cool factor about it. It works very well and is LOUD. I mounted the alarm on the seat post. It's mounting system is secure and solid. No worries about it vibrating loose. I do not know about battery life as of yet however it is easy to remove for charging or can be charged in place using a cell phone charger. Price verses value, it's a lot of bang for the buck.

This is a great little alarm and on the highest volume, it is loud! I bought it to help deter motorcycle thieves and I think it’ll do the job unless the thieves are deaf, overly brazen or high on drugs. I need to quit testing this alarm just for fun because my ears are ringing!I took my first ride with alarm installed today and I forgot to disarm it after coming out of a store. I started to unlock one of the hard side luggage boxes and the alarm gave me the warning beeps to remind me that I forgot to disarm it. It's a great feature and I appreciate it. Anyway, I presume the alarm comes pre-set on the highest sensitivity setting and since it reacts to a mere key inserted into the luggage, that's quite sensitive, which is great. Also, today was a very windy day, with gusts blasting at the motorcycle and that did not set off the alarm, in case you are wondering about wind. Only me fiddling with it prompted the warning beeps. So I give the alarm a 5 star rating. Also, I detest complicated menus on tech products, and this one is simple enough for even non-techies like me.Edit: I still have this alarm 2 yrs later and still love it! Just saying... :)

I just installed this. My friend purchased a similar unit but the alarm in housed in the rectangular case and uses batteries. This unit is very small an unobtrusive, yet very loud. Has micro USBC charging, which is really convenient. The mounting hardware is very sturdy and can go anywhere on your bike out of the way.

Seller : Don't claim this thing works on 'other' vehicles as well as bikes. It doesn't.Tried this same form factor/device from other sellers. They ALL don't work on Golf Cart or ATVor any other vehicle with more than 2 wheels.If you're looking for a wireless alarm for carts/atv etc. You won't find one. I can't.
