Unfortunately, the named brand ones are ridiculously expensive (£12k+) and having ridden a couple of Chinese made motorcycles I'm disinclined to go for the cheaper ones (£3-5k). Especially when you consider that even if the fuel cost were completely free on the electric one it would take nearly 5+ years to get the money back given a named brand 125cc petrol scooter can be bought for next to nothing and will struggle to use more than £10 worth of fuel a week.
For me it would be an optimum balance of environmental consciousness and convenience though. I guess that is worth something.
