This sounds like class A1 vehicle (up to 125 cm3 for ICE, up to 11 kW engine power, up to 0.1 kW/kg engine power per mass of vehicle)
With my class B license (the usual normal car license most people have), the only two-wheel motor vehicles I'm allowed to operate are class AM mentioned by the parent comment above.
For operating class A1 you need a class A license.
"B licence holders in Czech Republic (only motorcycles with automatic and semi-automatic transmission), Italy, Latvia, Slovakia (after two years and only motorcycles with automatic transmission), Spain (after three years), Poland (after three years), Portugal (at least 25 years old or additional licence for mopeds), and Belgium (after two years) are allowed to drive motorcycles not exceeding 125 cubic centimetres (7.6 cu in) within the respective countries."
So roguhly 1/3 of EU population is fine just with B license. In other countries you just need few hours of training.
You can't 'fail' CBT and any motorcycle instructor / downtrained instructor can write you a certificate once you have completed the required steps and are deemed competent. This takes half a day to a day and has to include 2 hours of supervised riding on the road
Many people who don't want to ride bikes with more than 125cc never get their A license and just retake the CBT every 2 years. Most delivery drivers or parking wardens etc. I have seen do this too
Not sure if the EU is similar or not
And the specs mentioned in the artikle "...his brake layout again confirms that the bike is intended to fit the “50cc” moped category, with a top speed of 28 mph(~45 km/h) and no more than 4kW of power"
And if they don't care about license then more than 1/3 of Europe (population) have A1 already with B license anyway, so why use pedals then, this seems like really odd niche for teenagers, since if you are adult you either have B license (and pretty good odds having A1 anyway, so you have much higher limits) and you can drive electric motorbike without pedals or don't have any license and you are not gonna make AM specifically to ride this moped, if they wanted to target the group without license they should add pedals (which they did) and weak 0.25kW electric engine (which, they won't), so this is really motorbike for teenagers, otherwise they should ditch pedals and can put there stronger engine if it's intended for adults.
But AM vehicle category don't require pedals, so the pedals seem pointless.
1 kWh motorized bicycles do not require a license or vehicle registration here. You just need liability insurance on your bike.
