Interesting to see the pricing for the Wisper 905e as they are sold in Australia. These bikes are similar, although not the same as the greenewheels electric bike (e.g. 7 speed gears instead of 6 speed). They appear to use the same frame and motor, but a quite different control scheme, possibly as they were designed to be sold in the EU where a quite different set of laws apply to power assisted bicycles.
They even have a youtube video
