I believe that there have been some teething troubles with the Vectrix, but it is a brave attempt to get something to market that could meet the needs of a lot of people.
The price is the real stumbling block, as it's competing head-to-head with cheap Chinese ICE powered scooters, that are awful lot cheaper.
As someone who's part way through the build of an electric moped, albeit based on a Yamaha RD50MX motorcycle style machine rather than a scooter, I can definitely see the attraction. I'm hoping that my converted moped will meet the majority of my local travel requirements, so eliminating probably 50% or more of my car use.
What bothers me is that potential customers seem to be hung up over range and speed, often having quite unrealistic views of what they really need. I've had several friends comment that my target range of around 25 to 30 miles, and top speed of around 40mph (don't tell DVLA/DfT etc!) is way too low. When challenged about their daily journeys, most have reluctantly admitted that they don't need more performance than this. I think this is one of the hurdles that electric vehicles still have to overcome, as the "milk float" image is still a very strong demotivator in the minds of a lot of people.
