Review on iENYRID Bike Alarm: Remote Control, 110dB Loud, Wireless Anti-Theft Vibration Motion Sensor. Vehicle Security Alarm System for Waterproof Bicycles, Trailers, and Motorcycles. by Brannan Mclemore

I bought it for my e-bike. It was easy to install. What I liked the most is that it is very easy to set different sensitivity and tone levers using the instructions. The built-in battery lasts quite a long time on a single charge. It's been two weeks since I got it. Charging is easy with the included USB cable. It can be easily removed from the socket or laptop and attached to the charging cradle. It calms me down when I park my e-bike in front of a restaurant during the lunch break without locking it. The design is excellent. There are two small soft plastic pads for the mounting bracket, and the design allows it to be temporarily held on the bracket without falling out. This small detail shows the overall quality. I bought two more as gifts for my friends, they love it.
