Hi Andy, thanks for that, I hadn’t considered an alarm. I was going to have a cable through wheels and lock but it’s the D lock I need to sort out so I can secure the bike to something substantial.
I have two Chinese made (supplied with my Bike), large sort of chain type with 5 or 6 links, each about 6" long (from memory, if you want exact details, I will go in the garage for you and take a picture!), and covered with a plastic film so that it does not scratch. They do not seem to be selling it anymore.
I could not pick the lock, which is an interesting design, that I have never seen before.
Maybe someone here can help better to find a good bike lock or three!.
On my e-bike it fits through the frame and the rear wheel, also around a fixed stanchion or similar.
I use the other one to anchor the front wheel to the frame, as that wheel has a quick release mechanism, and could easily be stolen.
With cutting disks on battery powered cutters, nothing is safe today (sadly!), but two or three bike locks, and asensitive and loud alarm, seems to have put off my "local" thieves, up to now at least!
But a better alarm, probably one that can send text messages to my phone, which will be a new GPS tracker, as my old one has overheated and will not charge, is one of my priorities for the near future.
The GPS trackers I have used, could place my bike within a meter of its actualy position, far better accuracy than was actually claimed....
That may also be an alternative for you, as if the tracker gets vibrated (when correctly set up), you get a text message....
regards
Andy
