I bought the new, necessary bike mount (€ 17,99 including shipping costs), and the new spine mount adapter (€ 22,99 including shipping costs). I don't know if I'll use the M3+ mounted on my handlebars very often, but I was curious to see what it looks like. The spine adapter attaches to the M3+ with a screw, and you can then attach the loop carabiner to it if needed. The spine mount adapter itself weighs 12 grams, and the loop carabiner weighs 14,5 grams, the M3+ weights 126 gramms, so the total weight of the three components is 152,5 grams. I think I'm too lazy to unscrew the adapter and it will stay permanently at the device.Here are a few pictures:
A nice little detail on the bike mount: when you slide the device onto the bike mount, the movable part marked 1 locks and secures the device. To remove it, you have to press the lever (marked 2).
