EN 15194 is a directive not a law, for it to be law individual countries have to write it into their own traffic law.
France did that, the whole text without modification, the UK did the same thing. No other EU country made EN 15194 law
UNMODIFIED, some parts are used but no all of them. As EN 15194 says explicitly one motor of 250 W
nominal power, many other countries have written that as maximum power for example. The podbike is illegal in France on french roads because it has two motors, maybe in Germany/Austria/Switzerland two motors are not a problem but that depends on laws in those countries, not the EU. In France the fine for riding an illegal pedelec on the road is 20,000 € (yes you could buy two or more velomobiles with legal pedelec support for that amount...).
Legal problems aside for the country I live in the podbike is also pretty inefficient compared to a velomobile with a chain. It uses the false theory that a bike chain is complicated, dirty, fragile, requires lots of maintenance, etc (they can be of course, but mine aren't). Bike chains have been around for over 100 years they must be doing something right - like being very efficient at translating rider power to the rear (or front) wheel(s), up to 98% on very efficient versions of the bicycle. The day a podbike has over 95% of energy efficiency (proven by an external test center) I would look at one out of interest. It is also very heavy which increases its inefficiency, especially in Norway and especially here, where I live (hills)
@beate the Citicar Loadster is a cargo bike which weighs 180 kg and uses over 26 Wh/km, think of how much further it would go with a chain drive on that big battery. There is also a special category for cargo bikes in some country laws which allows them to use more powerful motors while retaining the 25 km/h assistance limit.
