There is an article somewhere saying that the top three in the Tour de France in 2012 rode three different brands and all three frames came from the same factory in China...Except the 'Spanish' e-bikes are often fully manufactured and assembled in Shanghai....I have a pile of EN 15194 certificates that are from a very well known Spanish e-bike supplier that are from SFS Shanghai.
We cannot assemble a bike for 50 dollars like they do in China and the U.K consumer demands product as cheap as possible,sadly 'made in the U.K.' has no price cache.
I have some of the Kudos bikes made in Tianjin,the manufacturer is an expert at making frames and seats,I was shown around the factory and there are piles of frames on pallets with well known Austrian and German ID labels,some even have labels in German!!!!
This manufacturer produces some wonderful product,the quality of their welding and the heat treatment facilities are expertly controlled. They make some beautiful sports bikes,with high end spec (D2 electronic gearing) but the anti dumping duty makes it uneconomic to import to the UK.....maybe post Brexit if the anti dumping duty is eliminated it may be attractive to import to the UK?

"Orbea designs and builds bicycles, with some of the higher-cost bikes being made in Portugal but all the others made at the Orbea factory in Mallabia"
I chose Orbea on purpose, the factory is 75 km from here.
My point is that you can make e-bikes in Europe and they can be competitively priced on the market.
