Like the other replies, I'm sorry to hear about the theft an have plenty of gas to throw on the fire but that won't help.
I also ride a bicycle, a relatively cheap one because I have planned ahead for the possible theft, what would I do if I'm there, or not, etc... The reason I mention this is that in the cycling community there is a list where you can report your bike stolen and often they are recovered. They did actually locate a person of interest that does things like act as a broker for the thieves to take stolen bikes to. If the bikes are inexpensive enough they resell them locally. If they're in the 5-15k range they'll advertise them out of the country to avoid possible detection by the victim and/or LE and if there's interest they'll transport them to whatever locality where there are buyers, so long as the economics make sense. I suspect the same holds for any stolen item: an e-bike, firearms, etc.
The smart and imaginative criminals are very creative. Anyways it might be worth your time to try to locate a similar list where stolen e-bike information is aggregated. I don't see it being a privacy issue for you nor exposing you to more security risk. Hope this helps.
