Thanks to Robert for this link -

http://www.myswitzerland.com/en-au/e-bike.html

The tourism site lists about a dozen e-bike tours, all nicely described and with maps and photos. There's also a listing of shops that hire out e-bikes (and ordinary bikes).
Something like this would be nice for Tassie - we're not as hilly as Switzerland, surely.
As well as that,  the website has a route planner that covers walking, cycling on paths & roads, mountain bike riding, skating and canoeing.
