I've just found these on the web - they're foldable electric bikes from New Zealand. I know they go against the ethos of getting out there on bikes and doing exercise but on the other hand they could be the greener alternative to cars for commuters. I think they're brilliant, if rather expensive though I expect that in time the price may come down.
