I am quite interested in the evolution of electric bikes and cars, but they're not quite there yet. Take motorcycles for instance. For £10,000 I can buy an electric bike with the same performance as a £2500 125, that'll average 145 mpg, but it has about a third of the range as the 125 on one tank of petrol, and takes hours to charge. It just doesn't make economic sense yet. When it does, I'll consider it.
