(Hope my question not covered earlier in the tread and I can't recollect every point made but) if part of the reason for limited enforcement the difficulty with identifying if a bike is legal or illegal. If an officer suspects a bike is too powerful is there an easy check on the spot?
If no easy means to identify are they ways to properly identify legal bikes with some certification system? Maybe a bit like the CE system where fake CE marks are illegal (I believe) and importing with a fake make would become illegal.
(nb I'm not familiar with law, etc. so thinking aloud and happy to he corrected).
Legal bikes bought as such have to have a "plate" on them somewhere
mine is on the bottom bracket
but it is basically only a very good quality sticker that won;t come off
I saw a "kit" somewhere that came with a sticker anyway
I have also seen from some other countries a thing where they could put the bike on it and see how fast it went
but how the detect if the motor cuts out I am not sure
also - there is - apparently - some "allowance" as to the cut off speed - I think it is 10%
but I think they look for the easy wins
such as a hub motor the size of a dinner plate
and a clearly visible throttle - which is easy to test for if found
If they tackle all of them then the rest that are only a bit dodgy are much less of a problem and could be looked at later
