I've had mine stolen, and the insurer doesn't want to pay because it's not considered a personal good because they deem it a motorised vehicle. This is a snip from their terms:
Items not considered personal goods are:
› airplanes, automobiles, boats, motorboats or any other motorised vehicles and their
integral parts and installed accessories
These conditions implicitly say that motorised vehicle refers to ones that require a vehicle registration and licence to operate. VicRoads state that 'power assisted bicycle is identical to a pedal powered bicycle, except it has an auxiliary motor.'
Naturally I want to challenge the insurers decision as it's certainly not fair.
I tried to argue that my drone was a camera as its primary purpose for me is taking photographs, but nope, I had to purchase portable cover and it's registered as sports equipment. I doubt you'll have much luck with this sorry :(
