Rechargeable G Keni Bike Tail Light: Brighten Your Ride with Safety and Style

Amazon Customer: I live in a condo that looks out on a canal. It is very scenic but also very open. I keep my bicycle on the lanai. I should say I kept my bicycle on the lanai. It was stolen. I was naive back then, we left the screen unlocked and the bike unlocked. After the theft I bought a great new bike and learned to lock the screen, but I felt I needed something more. My internet search led me to this G-Keni light/alarm. It is FANTASTIC.

F.B: The media could not be loaded.  Easy to install and exactly what i was looking for. It does not ring for nothing, it first give a 2 beep warning and if the thief touch the bike again it starts for real !! I recommend 110%

Knobby-Camp: I was under the impression the bracket for the underseat option was aluminum...it's plastic. I painted a razorblade black and hot-clued it to the light-housing...all it will take is to yank on it and the whole thing will break right off if the siren goes off, but, at least they will leave some DNA behind and need some stitches. Aside from that, all else is about what you'd expect for 30 dollars. It flashes bright enough to alert all but the most braindead bubblegum chewing moronic texter to your presence down the shoulder. I bought it for that light, and thats what I cared about. The brake light feature falses the whole time I'm riding...my wife rides behind me and was annoyed because she knew I wasn't hitting my brakes.

Ralph QuirionRalph Quirion: This bike light/security device is decent for the price. It was easy to install. The light is bright and clearly visible. The round one I got shines bright when you slow down. The horn is fairly loud. The security siren works if you jostle the bike.

Here's what I don't like. The 2 "smart" light modes are actually pretty stupid. If you stop for 30 seconds (eg at a busy intersection) the light turns off and does not come back on unless you trigger it. It's under my seat, do you think I know it turned off? No. Luckily, there are 2 normal modes that don't do this and still trigger the extra bright stopping light.

My next issue is more of a concern. In the pictures I provided I showed the fob opened with a dime for reference. The non rechargeable battery is WAAY smaller than any AAA or AA battery. I haven't looked for this type of battery yet, but I'm worried about being able to replace it when the time comes. Again, the light is rechargeable, the remote is not. You can change the light function without the remote, but you can't use the security without it.

KevinKevin: I recently purchased a beautiful new Gazelle ebike. I also purchased two kryptonite locks (one ulock and on chain combo lock). The bike was a $4k purchase so the last thing I want to do is buy cheap locks.

While I was looking for a trunk bag I happened upon this little unit and I'm so glad I did!
Installation is pretty straightforward and they even supplied the allen keys used to secure to the bottom of the seat, it was a little finicky and I had to install it upside down due to the cane creek thudbuster seatpost I have installed. All in all it took about 5 minutes to get secured.

The unit is pretty easy to use and once armed does a good job of alerting. The alarm is reasonably loud and will definitely get your attention if you set it off in an enclosed area. The alarm is motion sensitive and the first trigger is short then resets itself. If the bike is moved again then the alarm really goes off! Cool, I can hardly wait to watch some curious onlooker try to sit on my bike, lol.

Of course nothing can replace the security of having good anti-theft locks on your bike but this little gadget is so inconspicuous (it looks like a normal tail light) that I think it...

Tim KlineTim Kline: Having indulged myself with a very $$$ e-bike, I was immediately concerned about having it stolen. Researching anti-theft ideas, I came across the Keni Bike alarm. Let me state in no uncertain terms: this is terrific item.

It arrived promptly, and installation was easy (the directions are a little badly written, but you really do not even need them). The light is nice and bright, but in fact I do not use it much, preferring to reserve this as an alarm and use a clip on other tail light I have. So for me, this is an alarm first and foremost.

The fob is more than decent, sending the signal right through our house from the first floor to the basement where I store my bike. It's as good or better than the fob for my new car! I got in touch with Kenny and got him to send me a second fob, which he did for a small amount, and it was easy to pair with the alarm. I have peace of mind with two fobs.

Setting the alarm is easy. You just push the alarm key on the fob. The trick is, do not move the bike until the second beep, or you will cancel the alarm. Once it is set, it is very sensitive. Some have complained about it being too sensitive, and being set off by the wind....

Kellin QKellin Q: Alarm:
Once the alarm is set, any movement of the bike at all will set it off for 30 seconds and remains in alarm mode until it's deactivated or dies. The alarm can be shut off with a press combination of the blue button if you set it up, but if you don't set it up I'm pretty sure all it does is turn the alarm on. I don't use it so I don't know. As for loudness, it's LOUD. You'll very easily hear it if you go into a store. It's about as loud as a car alarm, but not quite.

Light:
It's not the brightest tail light I've seen for a bike, but it's still plenty bright. Covers 180 degrees easily, although loses brightness towards the extreme side angles like you'd expect. Has three modes: slow blink, fast blink, steady. Makes a very quiet noise when the light is on almost like the PCB allows for a tiny bit of current to go into the alarm speaker. You can only really hear it when trying to, but I guarantee this decreases battery life.

Remote:
The remote range is easily as advertised and you can extend the range a bit by pressing it upwards against your chin before pressing a button as your head will act as an amplifier. It's very light and feels cheap so I'm not so...
