Hi there,
We had the insurance taken at Lemonade (
https://www.lemonade.com/nl) for a few years now and had good experiences so far.
We pay 27eur/month which consists of insurance for House contents, Liability, accidental damage, and theft for all our bikes (not just one), including the Babboe E-City that we had until it was picked up, last June.
For bikes or other things (phones, computers, etc) below 5000eur, you don't need to do anything special, it is just covered, inside the same policy. And for bikes, it covers theft anywhere, not just at your house.
Worth taking a look.
