WSDCAM Wireless Bike Alarm with Remote, Rechargeable Bicycle Alarm System Anti Theft, IP65 Waterproof, 113dB Loud Bike Alarms for E-Bikes, Motorcycles, Scooter, Outdoor Riding and Cycling Safety

loud for what it is. i like that you can charge it, battery has lasted about a week so far strong. would buy again, excellent condition and the fob was really cool and user friendly. wish I had got the bundle deals w more alarms. super sensitive. great for security and peace of mind. works amazing, super functional

This is just what I needed. I recently had one of my bikes stolen and when I purchased a new one, I wanted to make sure it had all the security features in case I had to leave it unattended for even few minutes. This alarm is so loud and does exactly what it says. My brother got so annoyed with me testing it indoors he had to leave for an hour lol. When i did it outside, I think it's what made other car alarms go off, haha. t works well.

Great nice and loud

This is very easy to use and it is very LOUD. I like the fact that the alarm is rechargeable and the remote make it easy to arm and disarm. Hopeful this will help keep out e-bikes safe.

It works and it's loud. However, if someone is determined to take your bike they will still take your bike. I would only use this in conjunction with a good bike lock. With the alarm as an added layer of defensive against theft, it should make thieves seek an easier target.

works well! many options!

It’s loud and don’t have to replace batteries as it is re chargeable.

Works well
