Sakase Bicycle Wireless Rear Light Cycling Remote Control Alarm Lock Fixed Position Mountain Bike Smart Bell Tailight

It appears that there are several manufacturers or distributors of this bicycle Light/Alarm. I've seen this product listed by; Amrka, Longfite, G Keni, Xiaokoa, Sakase, Antushi, and Antusi. The price ranges between $12 to $29. To get the best price, search Amazon for "bicycle alarm" and then browse the similar products.I would suggest that you avoid the competing bicycle alarm product that doesn't feature a light, has the two button remote, and requires a 9v battery. If you do your research, it eats those 9v batteries VERY quickly.If you're only interested in an alarm and not a light, there's a very similar product on Amazon by wsdcam. It doesn't feature a light, uses three AAA batteries, has an adjustable sensitivity feature and 6 different bell sounds. It attaches to a bike via a double sided sticker or Zip-Tie. It usually sells for about $13 to $19.My review of the productI ordered from this product listing and was sent a version of this light/alarm manufactured by ANTUSI. The box says Antusi Cicada A6. My cost was $16 + free shipping.InstallationIt attaches to the underside of your bicycle seat by way of a two piece plastic clamp. Two screws and tools are included. Depending on the design of your bicycle seat you may need to install the unit in an inverted manner (upside down) or get creative with the extra ZIP-TIE included. If you have a standard/common seat type the installation should be straight forward and easy.My seat features two small "springs" under the back (for comfort) and I was unable to install the unit in it's preferred configuration.Inverted/upside down installationAn inverted installation (upside down) creates some issues; (1) The device may be more difficult to detach when needing a charge. (2) You probably won't be able to install the screw that attaches the unit directly to the clamp (it offers added protection after you snap the unit into place). That means the unit has a higher possibility of coming loose and that someone could more easily pull the light off your bike. (3) The speaker area will face UP, and depending on if it extends beyond your seat - it may collect water if you ride in the rain.Attaching to the seat postIf you look closely at all of the Amazon listings by the various manufacturers/distributors you'll notice that some offer an additional bracket to allow attachment to the seat post. View the images for each listing to see if that's included (the bracket will be shown in a product image). The unit I received didn't have such an attachment.It may be possible to use one of the two ZIP-TIES included to attach the unit to the seat post. Assemble the under the seat attachment, snap the unit into place, then run a ZIP-TIE through each side of the attachment and around the seat post. As an example I'll include a picture of the ZIP-TIE running through the attachment.In my particular circumstance, the unit was more difficult to install than I would have preferred. Every unit should come with both the under the seat and seat post attachment.FunctionalityIt comes with a very short USB cable for charging (for connecting to a laptop, etc). But, you can use almost any cell phone charger that has a micro USB plug (currently the most common type). The main light will come on when charging and go out when fully charged. It would actually make more sense the other way around. Charging is very quick (it took mine about an hour or two to charge).There are two buttons on the unit. A red button that cycles through the available modes for the light. A blue button that's used to pair the device with a remote, should that need to be done.The remote can be attached to a keychain or easily snapped in and out of a cradle that attaches to your handlebar with a ZIP-TIE (included). There are four buttons on the remote, from top to bottom; LOCK (set the alarm). UNLOCK (turn off the alarm). LIGHT (activate the light and cycle its modes). BELL (can be used like a bike horn).The light is INCREDIBLY BRIGHT and the alarm is VERY LOUD. It definitely performs well. If your bike is bumped, it let's out a warning chirp. If the bike is moved in any seriously jarring way then the alarm goes into full action. You can turn it off immediately with the remote or it will turn itself off after a minute or so. A very effective deterrent to theft.Final ThoughtsWith the exception of a potentially difficult install (depending on your seat) and incredibly poor instruction manual, I think this is the best bicycle LIGHT/ALARM combo currently available.

Unit seeming is working great, nice light, good alarm, the bell is loud but could really use a different sound such as a bell. This is a replacement for a unit that did not work. When I got it it too did not work, I thought to go on line see if I could find any information, somehow I managed to get it working. I still have question on why when charging it it stays lit solid red light there is nothing in the instructions about this & my believe is it is telling it is charged. More evening rides to come.

Wow this is really nice I use it all the time when the bikes are loaded on the back of the RV as a deterrent and anytime we park the bikes after riding. The flashing light is also really nice when riding and when the alarm goes off it’s pretty loud.

Very satisfied as it fits nicely under the seat and works as advertised. I especially like the fast flashing for the tail light... alarm sensitivity is just right.

Sensitive, loud and good rear light performance. Easy to install but not easy to uninstall. Not very convenient for charging. It cannot be normally at all: when the cable connects, it just keep shouting without charging.

great item

I have one and gave this as a gift

Works great. Short battery life
