Nice find!

I like it but where's the battery goes the lid can easily b taken off and can b shut off by removing the battery if there was a way to conceal the battery where you put on the seat bar now that will keep the battery concealed and it won't get wet if you adds a rubber peace around it so that no water can get into it and you won't lose your bike and it will b water proof but I don't think anyone thought about that when they were building it

To change the sensibility I open the case and changed position for sponge inside.

I ride an e-bike, which is like a magnet for theft.

This is so cool. Now when I am just going into a convenience store and will be within a few yards of the bike, I don't have to padlock it. I also use it with my lock just to deter someone from picking the bike up and throwing it in the back of a pickup.

I have also 'accidently' set it off after arming it if I don't like the crowd around where I am parking my bike. You should see the look on some people's faces when they hear what sounds like a car alarm on my bike.

Easy to install
