I have the third one with the alarm. Someone tried to steal my moped while I was working and it stayed In place and saved my moped from being stolen. I highly recommend it especially with a moped.
Sadly there’s nothing to stop a bike or car from being stolen. If something is made then it can be unmade. Every 20sec a car or bike alarms is chirping in the background, and people are just not interested and have become accustomed to noises that it’s just how it is. Thieves just uses dolly’s now and in less than 5 min the bike or car is on the tow truck and she’s gone.
