Getting back to the original topic - the discussion of illegal bikes on the forum as opposed to the issues surrounding their use - I think it's a good thing. Laws are there (or should be) to balance the protection of society against the freedom of the individual. But laws change as society's needs change and other factors, sometimes technology-based, come into play. The laws governing motor vehicles are a lot different today from when we had men walking in front them waving little flags. The only way the people can get laws updated over time to better match the needs of the day is to discuss their pros and cons in an open forum, reach conclusions and, where necessary, lobby the lawmakers. That discussion also provides a mechanism for those who think the current law should be strictly followed to convey that opinion to those who do not. It also allows anyone to criticise someone who boasts behaviour that would be widely recognised as irresponsible, so demonstrating that the forum members are not just a bunch of anarchists who need to be controlled.
Personally, being new to e-bikes and having test ridden several recently, I think the UK law as it stands errs too much on the side of protection and does not give the individual enough freedom. When it falls in line with EU law and pedalling becomes mandatory it will be even worse. I'm not arguing that we should all be allowed to hurtle around at 30mph untested and uninsured, but the current limits provide so little benefit to many would-be casual riders and commuters, especially given the typically higher cost of an e-bike, that they do nothing to encourage people to use their cars a little less and get a little bit more exercise (both in the interests of the society the law is designed to protect - surely?). Yes, if you have a trick knee or a heart condition then a bit of electric assistance can make the difference between cycling and not, but for a lot of healthy, but not necessarily fit, individuals, I believe the bikes that stick rigidly to the (forthcoming) law will be largely unattractive.
The natural outcome of that is a) e-bikes will become more expensive as volumes drop, b) some current manufacturers will go out of business, c) more people will be forced to go for illegal bikes.
So I say discuss it. I don't expect the law to change in the other direction, but we shouldn't be afraid to say we don't agree with it (if we don't) and pretend that we are all sticking to it (if we are not).
