BTW wrt the above....have you noticed the growth in electric mopeds/bikes?
Here they are taking off fast as the battery tech has improved enormously.
e.g. 50 mile range 15-30 mph & coz they're classed as bikes no helmet,
insurance, road tax, licence etc.

I was looking for a twist & go moped for my wife as she would like to
go to the farm & back/town & back etc but doesn't like cars. So 
thought the std 49cc tist & go moped would be what she needed. I spent
the whole evening looking at electric bikes & mopeds etc. V. impressive

e.g. search ebay for "moped electric" & have a look.

e.g.:

"New Electric Motorbike Motorcycle Moped 30MPH 1500W".

I am sorely tempted.
