I'd say in most of the EU you can ride <125ccm motorbike with regular car license, so this changes nothing at least in EU. Heck, I don't even know what is supposed to be "50ccm" ebike, ebikes are limited by laws in regard to their power wattage (250W) and speed (25kmh), not volume. Specifically EU directive says for pedal assisted ebike is this: "cycles with pedal assistance which are equipped with an auxiliary electric motor having a maximum continuous rated power of 0.25 kW, of which the output is progressively reduced and finally cut off as the vehicle reaches a speed of 25 km/h [15.5 mph], or sooner, if the cyclist stops pedalling" Everything else ain't ebike and requires some sort of license. Though of course the reality is police won't be checking every single ebike on road and they have no way to meaure the power.
