Similar to a car's one

I'm sure you have two different numbers on the frame. My S-Pedelec has a serial number WSBC... like any other Specialized bike but the VIN is in several places and it starts with 55
EVB...
Definitely, it is one of the requirements.
Another requirement is to have an operable speedometer.
@jabberwocky: We are discussing with
@stompandgo whether he could bring his S-Pedelec to EU. Yes he could. However, the bureaucracy is terrible here. Let me tell you I could complete the whole procedure for my Vado 5.0 45 km/h back in 2019. My e-bike had the number plate and everything. I was paying a modest Third Party Liability insurance every year. Now, wherever I stopped, people were asking me about the number plate. I was bound to ride with traffic, which was greatly misunderstood by drivers, Police, and City Guard. Eventually, the disaster struck. Three years into the ownership, the frame cracked. Yes, the frame with the VIN. Specialized has replaced the cracked frame with a new one, bearing another VIN. My e-bike was upgraded to 6.0 by the warranty. I also got a new EU Compliance Certificate.
It all meant, my old registered vehicle ceased to exist but it was under the insurance I would have to pay infinitely if I didn't deregister the vehicle. No junkyard wanted to scrap my frame with all the paperwork necessary! Finally, I contacted some "scrap metal hunters". I had to pay the "hunter" a small fee for his trouble, and gave him the cracked frame, the broken motor, and the number plate. In turn, he signed the purchase contract as if he bought the e-bike from me. Now, I entered the documentation into the Transportation Department website and got my Vado instantly deregistered, and I also could cancel the insurance.
This sounds like a real ordeal, and it indeed was an ordeal. Now, I
didn't register my Vado 6.0. I ride it as it were a regular 25 km/h e-bike, slowly and on bike paths whenever required. If I ever ride the S-Pedelec fast, it is only on road with the total absence of traffic. Even if I use that e-bike in gravel races, my average speed is below 25 km/h not to make the impression I'm cheating because I'm not.
