Folds compact but is quite heavy. Holder can be velcro strapped to bike or mounts on standard water bottle mounts.

Comes with a pair of keys, one lighted. The all important card to order spares.

Lighted key.

Lock folded.

Opening up.

Forming a loop.

I don't use the holder. I use the velcro loops and slide it under my saddle.

It sticks out a bit but is secure.

It doesn't get in the way of my luggage.

I haven't tried it with the saddle bag yet, but I would probably carry it inside the bag.

BTW, I have a new spare in the box, if interested PM me an offer with your location.
