Wsdcam Bike Alarm with Remote 2 Pack, 113dB Wireless Anti-Theft Vibration Motorcycle Bicycle Alarm Vehicle Security Alarm System (Blue)

Less than a minute to install (though zip ties were too thin), it is a very powerful deterrent! Love it! Price was great too!

I like that the units give you a warning blast if there is a single bump and then goes off. If you continue to bump or bump hard the first time it goes off and has to be turned off with fob. I was able to get both fobs to control the two units so can put on my two set of keys. Overall I am very pleased.

Put on both my bikes, very cool, kinda loud, and works well. This is just a deterrent and with a good lock this becomes a nice system for alerting U if someone’s messing with ur bike.

I found an alternate use for these when not biking. I sit them on top of our bathroom garbage cans. Our dog decided that rummaging through the garbage is great fun. Not anymore. We heard the warning and he hauled a$$ out of the bathroom like he had been shot out of a cannon. The slightest bump activated the warning! I have my portable security camera aimed at the setup hoping to catch him in the act again!

Good for my car

I attached this to my recumbent trike in order to prevent theft and vandalism while not actually riding. It seems to work well, giving a warning beep before sounding off loudly. A touch of the bike will set it off.

Delivery was fast product was nice, easy to install and use.

Added these to our eBikes to act as a deterrent to opportunity theft. They were easy to mount and set up.

THESE ARE GREAT TO PUT IN REMOTE LOCATIONS.. GOT ONE GLUED TO A MAGNET AND STUCK DOWN ON MY NON RUNNING CARS CATALYTIC CONVERTER. . . JUST FOR THIEVES..

I liked it all
