I forgot to tell you that I also put a disc lock and I have a cover. the perimeter sensor tells you right away when someone goes near your bike, so you have time to react. besides, I parked the bike where I can see it, so I know who goes near it and I can see his intentions. I didn’t a qoute with an insurance for my bike and if you want the insurance to pay for the bike if it gets stolen, it is stupidly expensive. maybe I did something wrong, but with the money they were charging I could easily buy another bike in a year and a half.
