113dB Bike Alarm Wireless Vibration Motion Sensor Waterproof Motorcycle Alarm with Remote

Awesome little alarm. Works great Loud and responsive to the remote. Recommended Will purchase another.

There are already a lot of photos and videos of this product so I will not beat a dead horse. I can see where there could be some problems with placement of the alarm. If you were to put it in a place that gets more vibration or unmitigated shocks, I could see it being damaged. However, if you think critically about where you place the it, you should not have any problems. I installed this on my ebike and it has been working great. Too good, sometimes, like when I forget to turn it off before unlocking it from the bike rack or going to jump on it to take off from behind my house. Everything works very well though I have not gone in to change settings at all because the first time I pressed any button it was the emergency button, in my bedroom, and it was earsplitting. Seriously the neighbor upstairs probably thought... I don't know what I would have thought but it would have woke up the whole house and my ears were ringing. I have seen the issues some people have with the fob. Maybe they will eventually make one a little stronger so that you can put it on your keys, but for my purposes, I did not even really want this on my key ring and I had a better solution just sitting around anyway, which I will post a picture of. I just wear it around my neck but under my shirt when I have the ebike with me. Works great for me. The price was great for what this thing does. If you get a good lock and have this thing armed, I mean, as soon as a person would go to position their bolt cutter or angle grinder, this thing will start making some noise... very loud noise, and you really have to be in the hood for this to go unnoticed and for it not to scare the hell out of them. When I go into a store in the day I just park the bike in a car spot and arm the alarm. It ain't going anywhere. Try out a flat lanyard like in this photo for the fob and it should not break. For me, this is an easy five star item. I waited a little while to write the review just in case it broke early on but I have about a hundred miles on the bike and everything is perfectly cromulent. I recommend it. Thank you.

This bike alarm is easy to use and does pretty much what you'd expect. It has a lot of settings and different sounds you can choose from, which is nice. The instructions that come with it are actually really helpful, which made setting up a breeze. The battery will eventually need to be replaced, but that's expected. The best part is how loud it is, which keeps people away from your bike. Word of warning, though, do not test it in a garage; the sound genuinely hurts, and that's exactly what you want! Definitely recommend.

This alarm surprised me, its price is so low and yet it works VERY WELL! Its super loud like VERY loud. On my bike even a light touch will set off the first warning sound (which is great! Cause people will be deterred immediately). 2 things i wish were better tho are the size and weight of the alarm i wish there was a smaller option even if it means the batter dies quicker. And 2 is the big one i would like them to change!! When using the remote to lock/unlock the alarm the sound goes off at full volume and its painfully loud and immediately gives away the presence of your bike. Pls update this and make the locking/unlocking sound quieter!!

This is a nifty little gadget for your bicycle, e-bike or motorcycle. It works completely independently of the cycle's power. It runs on 3 AAA alkaline batteries. After watching some videos, some users got up to 18 months on a set of batteries. It was easy to install. It comes with instructions on how to customize it to your preferences or you can use it as it came to you. Just pull out the plastic tab on the alarm and that activates the batteries. Now it'll work with your remote. It comes with two zip ties and two adhesive pads so you determine how to install it. It's small, so it'll hide in lots of places. I put mine under the rear rack on my e-bike. Now when I stop and run into the store I can just hit the remote button like I do in my car and quit worrying.

This works great! I definitely feel better knowing my motorcycle has an OBNOXIOUSLY LOUD and SENSITIVE alarm while it's parked outside :) The remote is a good size, slimmer than it seems, the actual alarm is on the bigger side, but it still fit unseen!

very loud. easy to use and adhesive is very strong. use for my ebike and highly recommend

Lost a star because the instructions are nonsensical. I had to pore through a few YouTube videos to figure out how to change its settings. And, it has an odd SOS function that I accidentally engaged while trying to set ringtones, sensitivity, and volume. I had to reset the device to factory default to get the SOS function to turn off. Lost another star because you can’t select the motion alarm’s ring tone. You can, however, set the ringtone for the “find me” button. I liked those alarms sounds better than the default set at the factory for the motion alarm itself. But, this thing is LOUD. And it is very inexpensive. I’m keeping it. I have an older car that does not have an alarm and this is a cheap way to arm that car. Plus, I’m thinking of using the alarm for backpacking trips. I’ll keep it in the bear canister and arm it once I stash the canister for the night. Buy it; the price is right.

la sonnerie de l'alarme est fort réduite..argent jeté à la poubelle!

Un antifurto elementare ma perfettamente efficace e semplice da utilizzare, ottimo per bici. Ampiamente consigliato

After 2 years of buying still working well. They Key chain battery is still working. But buzzer's battery I changed few days ago. Very good build quality.

Seems to work as described and certainly is loud! Happy with my purchase and delivery, thanks!

On opening up the alarm to try out the batteries and the device, I had a concern. The screw seemed really cheap, as did the screw driver. I was worried about stripping the screw itself or the plastic. But I used my own Phillips screw driver and gently got that screw out to proceed to the next step of opening up the alarm box. They give you a plastic device that looks like a guitar pick and that was useless in trying to open up the alarm box. I got two slot head screw drivers and used those to wedge away at the tightly sealed plastic. I ended up chipping the plastic a bit opening up the two halves. Next, was installing the three triple A batteries. They looked real cheap, so I threw those away and used high quality batteries I purchased separately. The batteries installed securely. Everything looked intact inside, so I put the alarm box together again to try it out. Next, was trying to read the very, very small print instructions with my big magnifying glass. I gave up on that and went to You Tube to find instructions there and I did. So I slowly went through setting up the remote control’s three buttons. That went well and discovered, an excellent bike horn. The seven different high pitched alarm to chose from in pitch and the three different types of noise was a perfect deterrent noise. I don’t get my new e-bike until May and can’t install/ try it out until then. But I’ll install the alarm with the tie wraps and the two-sided stickers provided. The location will be under my seat in the posterior direction to keep it drier. Once you activate your alarm, by the remote button. The first disturbance (dependent on sensitivity setting you chose. I suggest the 4th level) your alarm sounds a warning short beep. On the SECOND disturbance of your bike, then the continued alarming begins. The noise definitely will attract onlookers and annoy your bike thief. This remote is effective for 60 feet away. My Apple Air Tag will be located under the bike seat, just inches away from this alarm - under black Gorilla Tape. The remote control will be located by my right thumb on the handle bar, because of that cool sounding horn. I use my plastic rescue whistle as well and a flicker bell alarm to warn people ahead, I am coming behind them. Then I announce verbally, “passing to your left” and carefully pass other hikers on the bike pathways. The color black blends into my seat and bike rack color and the looks of the alarm appears esthetically good for my bike. Overall, I am confident the alarm/ horn will endure a long time and will do its job to SCARE AWAY THE THIEF or at least slow down the bike thief. Even though the bike horn will be located under my bike seat, I am again confident pedestrians and other bikers will hear this horn. So good price and apparently good, effective bike alarm!!
