See if you can find an ebike shop in your area that has a bike with the Shimano STEPS system with the Alfine IGH. It can be configured to shift manual or automatic. My wife just tested one in the states, and after trying MANY others, she's in love with this configuration. The brand she found is Wallerang, but I don't think it's sold in NZ yet. The damn Aussies have it though. ;~)
