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

Great product. Very loud.

These alarms are great for our ebikes! Easy to install

Easy to work and put on works good

Simple to use and worked great. We installed in our ebikes and felt very happy knowing we had the alarms.

I used these alarms to help maintain security for our very expensive E-bikes. They work great, allow us to eat at a restaurant, and know that our bikes are secure.

Great Product; very loud

They work great! They are loud enough to scare thieves away!

They look nice and work well. Good envestment.

Got them for our new e bikes and we are very pleased!

Always skeptical of cheap feeling Chinese products but this alarm is loud and long remote range. Pretty cool.
