Wireless Bike Alarm + Ultra-bright Taillight + Bike Finder + Electric Horn; Loud Anti-Theft Alarm with Remote; Large Battery; IPX6 Water Resistant; Both Saddle & SeatPost Mount Included; FCC Certified

The order was very fast, I got it the next day, ordered it on Monday morning and got it by next day Tuesday (btw, im in Los Angeles).And the product is very good. Its very very useful and helpful.1. It keeps me safe so that i alert cars when im riding. Since this thing has a remote I can actually access the bell with the remote and so when I am riding thru traffic and need to alert other cars I can just easily press the clicker to alert. It would emit a sound loud enough to be heard by other cars. Really really helpful in my opinion.2. Keeps my bike safe against from theft. I like that the anti theft has a system program/warning built in too, so that when it is accidentally bump then it will still alarm but it will stop when it is just accidental. It would completely alarm if theres an actual theft happening.3. It can also be used as a bicycle finder, but i havent gotten to use this feature since i tend to know where i leave my bicycle. :-) But still good to have this feature and moreover the range is far.4. Also good thing about this is its waterproof.5. I can also use it as a taillight at night.The sound of the alarm is very loud, which is good, its loud enough to deter theft and alert the cars. This alarm makes my riding the bicycle as safe as a car. My bicycle is basically behaving like a car, having anti theft/ alarm system, bicycle finder, horn, etc. It makes me want to use my bicycle more often than my car. This thing has so many features, its worth the money for your safety and your bicycle. I highly recommend it. Highly satisfied with this thing.

I live in Pacific Beach (part of San Diego) and this area is known to have one of the worst bicycle theft problems in the country. And while no lock and/or alarm system can stop a determined, well equipped bike thief, a decent system can make a big difference on whether or not your bike is gonna be worth the risk involved to steal it. I'm convinced this alarm/taillight helps make that big difference for my converted Trek E-bike.It works exactly as advertised. The alarm easily arms and disarms reliably with the included remote. The alarm sound is very loud and will definitely bring unwanted attention to any attempted thievery. It also functions as a pretty good taillight and will last a couple of weeks or more before using a charger and a USB cord to charge up the battery. This is my third try with a bicycle alarm. The other two alarm products were not as durable and basically became useless after needing to be taken apart to change the batteries. This item costs a little more but is defiantly worth it. My only minor complaint (not worthy of removing a star) is that feedback "beep" response you get from arming and disarming the alarm is unnecessarily loud. It tends to startle people nearby and for no good reason since really only the alarm itself should be loud. A minor quibble on an overall very good product. HIGHLY RECOMMEND.

Taillight is bright & the remote clicks securely in it's bracket. Alarm is quite loud & functions as expected - short loud burst with the slightest touch of bike once armed. When the bike is touched again within several seconds, it alarms steadily & very loud! Some other reviews expressed concerns about having to unscrew the unit from the bracket to recharge it. I just use a longer charging cord to reach a nearby outlet while the unit is still securely attached to my bike. I prefer to keep it always screwed into the bracket so a thief doesn't just remove the alarm from the bike. Very glad I purchased this product!

Seems to have some problems with alert after few rides on mtb. I don't know how it's gonna work after mountainbiking for a while. Light works well

Awesome product. Light is super bright and good for daytime as well as nighttime visibility. Horn is loud for warning other motorists, but too loud for warning pedestrians ... need a bell for that. Love the theft alert function .. I have a TerraTrike Rambler 3 wheel recumbent trike, and I just arm the alarm and don't need to lock it up. Packaging was very impressive, more like something that costs $100, or more. Love through recharge capability. Highly recommended.

I've originally ordered the remoteless version, but soon realized that was a mistake!I use it along a Kryptonite U-lock to deter wannabe thieves.I've installed 1 each on a hybrid [photo #1], cruiser [photo#2] and mountain bike [photo #3].My only gripe with the product is the location of the charging (mini USB) port.The seat saddle mount is very secure and sturdy, but the charging port location makes it tricky to install under the seat, I ended up using a ziptie the cruiser. It's on the middle of the left side. The mountain bike seat worked the best [photo #3 & 4], but on the hybrid and the cruiser I had to install the alarm in a position where the light is not visible, because the the charging port would've been inaccessible if the alarm is installed between the shock absorbers of the comfort-cruiser seat. Both of those bikes had a tail light already, so not a big issue for me.Although the alarm comes with a seat post mount also, I feel the saddle mount is safer, because it would be very easy to just rip off the alarm from the seat post.Multiple alarms can be paired to 1 remote to avoid the confusion which remote belongs to which bicycle. When I leave from home with the MTB, I just use the red button [photo #3] on the bottom to turn on/off the taillight, using the remote could accidentally trigger the light on the other one of the bicycles near by.

I love love love it. Works well. I love the remote keychain. I ride my bike to the gym and lock it up. Works well. Gives a warning beep if disturbed. If you keep moving the bike, it sounds a piercing alarm. It also it's a great tail light.

Not a horn! It makes an annoying chirpy beep that no car will hear, & is too shrill for pedestrians.
