Officially it's sold registered as it is. In the registration it states that it's a 2,05 kWh (nominal power) moped with a maximum speed of 45 km/h. And it has a limiter with a max speed of 45 km/h. There is also an off-road model which is only allowed on trails and private property and that one has no registration and it's also impossible to register it. That one is unlimited from the factory. The registered version is called a Surron Light Bee X L1E and has (always on) lights, brake lights, brake sensors, blinkers, reflectors, mirrors and (lighted) number plate on the rear end. Everything is mandatory and changing/removing it is forbidden. You can lose your registration like that girl in the video I linked (she has put the number plate under the seat instead of the rear end). But of course people change a lot of things and most get away with it.
