Your latest post is dishonest, pretending you were saying users could be fined 10s of thousands.
You posted this quote:
"https://www.e-bikeshop.co.uk/
they sell and fit
dongles to the bikes, nothing ever happens about it and they honer the warranty as well, no other dealer can do this."
And then said:
"Well if the police use their powers then they can end up fined 10's of thousands and they are legally obliged to hold records."
Clearly you were saying ebikeshop could be fined, and that was not true, ebikeshop canot be penalised in this way. As I said, your post was mixing up supplier and user liability, the two things are quite separate.
ebikshop emphatically do not need to keep records of the dongles they sell, perhaps you are getting mixed up with vehicles that are intended to be registered for road use?
Of course users can be prosecuted and I posted as much, so I don't understand your challenge.
