Surprised by your data. I don´t think we reach 10000 here in Spain, never mind our proverbial beautiful weather.Probably nearer 100,000 e-bikers in the UK Poppy, believe it or not.
The market was roughly 20,000 a year for some years and is widely believed to have grown from that. Even if the bikes only last five years there will be at least 100,000 e-bikes here.
Have a look at the link below. You've probably never heard of this company or seen their bikes, but over several years they alone were bringing in and selling over 7000 e-bikes a year from just five shops.
Thompson Electric Bikes
That's still a drop in the ocean though, UK normal bike sales are 2 million a year so e-bikes are only 1%.

I´ve looked up your link, and it has given me pause. If I´ve been complaining about my Tucano, and wishing for a more powerful Panasonic, I can´t imagine how plaintive I would be with one of those. How good can they be at -at least- half the price of the bikes we are discussing in this forum. Some of them are cheaper than a reasonable good push bike!
