I have read your post very carefully - and indeed pointed you towards relevant recommendations to Parliament. I have also said I have a lot of sympathy with your points.
However, the language we use when talking about this issue matters and this is a thread where there have been some unpleasant comments about cyclists - because they are just cyclists. It’s your discussion, but you haven’t objected to them, which implies that you agree with them. I suggest you read the description of cyclists posted at 16.09 yesterday and some of the other comments about cyclists on this thread & you might see why I’m upset. You’ve said that your DH & DD cycle so you could consider if it’s a fair way to describe them. This type of language isn’t just used online - I’ve been shouted at just for being on a bike; I can also think of 2 recent cases local to me where cyclists were injured because the driver just didn’t think they should be on the road (one assault, one dangerous driving - neither cyclist was at fault). As I’ve said several times on this thread, we have to be able to discuss road safety without people having a go at cyclists simply for existing.
As for motorbikes, technically there is a good chance that the riders are motorcyclists if their e-bike is too powerful to be classed as an EAPC (electrically assisted pedal cycle). It’s the engine size that matters not the appearance of the bike. The actual rules are:
”If your electric bike does not meet the EAPCrules then it’s classed as a motorcycle or moped.
Your bike is not an EAPC if it:
can be propelled at more than 15.5 miles per hour (mph) by the motor
has a continuous rated power output higher than 250 watts
does not have pedals that can propel it”
(This should be a list of bullet points but I can’t get that to format properly - the source is “Riding an electric bike: the rules” on gov.uk ).
This point is often overlooked in discussions about e-bikes, but it is actually quite important. Firstly, because it means the rider should be wearing a motorcycle helmet, have insurance and a licence. Secondly, it means that the police will not exercise discretion if the rider is on the pavement - if the e-bike is a motorbike it has to be on the road. Thirdly,
it needs vehicle approval (which is why there is an Issue re illegal e-bikes as these are the ones without vehicle approval).
As for why all this is important to your OP - it’s quite simple. You want (understandably) the riders of e-bikes to be punished if they are riding anti socially - if the e-bike is classed an electric motorbike, then the rider is likely to get a more severe punishment.
