ZTTO Bicicleta bicicleta anti-roubo segurança alarme bloqueio alerta sonoro com controle remoto

The bicycle alarm arrived in northern Germany after 16 days. After unpacking, I noticed that it rattles a lot. But that disappeared after inserting the 9-block battery. The bracket is intended for 15 mm tube thickness (frame). But my Ebike has a 30 mm frame. It makes sense to mount the alarm system under the saddle. Screws are included. The remote control is already equipped with a battery (replaceable) and works immediately. The alarm volume is around 110 decibels. Triggered when the bike moves. If you press "close", there will be 1 confirmation beep, if you press "open" 2 confirmation beeps.

This alarm system for bicycles and scooters or installed on a trailer is flawless. The noise of this alarm system alone scares certain people. I've been using the same alarm system for my e-bike for over a year now I had to buy a second one to have a complete bike with trailer to secure

Hello Madam Sir I allow myself to write to you to tell you that the alarm does not work the red button to activate does not work please Madam Sir believe in my deepest respect tell me how we could proceed thank you in advance Mr: Drink

The instructions for this product are not very clear at all. It states that you can set the cade to what you want. By pressing ABCA to reset. But we're is ABCA. No letters no the device. So have not put it on my bike as yet. Still trying to suss it out.
