FAQs

Can the ebike alarm be used in the rain?

Yes, the alarm is IP55 waterproof, meaning it can handle rain and splashes but should not be submerged.

Is this anti theft alarm for ebike models only or will it work on regular bikes?

It works on most e-bikes, regular bicycles, and scooters — any vehicle where you can securely mount the compact alarm.

What kind of batteries does the alarm use, and how long do they last?

The alarm is powered by 3 × AA batteries. With normal use, they typically last several months before needing replacement.

How easy is it for thieves to remove the ebike alarm?
