I'm just going to reply, because there is a still a bit of confusion about a few things and I'm hoping I can clear some up.
Flecc and others have compared dongle'd eBikes to cars / mini mopeds / and other things that can bought and then can be used illegally, and suggested traders / importers aren't liable for an accident when they are used illegally. This is correct.
However there is an important difference with a dongle'd eBike. All the products you've used as examples are products themselves and tweaking, tuning them etc etc, doesn't change their category of product (legally), and is generally not done by the dealer selling them.
Excuse the boring detail, but it is important. An eBike is classed as a bicycle (BS EN 15194) if a dealer dongles it, it takes it out of this category, and therefore its no longer a CE certified product thats considered safe to be used. This is due to trading standards, and trading standards law clearly says any product sold must be safe. If a shop sells a bike with a dongle on it, its not tested, and not legally allowed to be used ANYWHERE, so do you think any competent lawyer would find it hard to prove that the shop was liable for selling it, under trading standards law.
There is a simple guide to the law here:

So that's why dealers selling dongle'd bikes are taking a massive legal risk, and why we have such a strong stance on it, and I'm frankly shocked Raleigh haven't checked / realised.
If you as a customer buy a bike and then buy a dongle... the dealers of both products (bike and dongle) are legally untouchable and its you as an individual who is responsible for creating this illegal vehicle and taking it onto the public highway.
For us as a business, if customers want to dongle bikes and use them on the road, its stupid and risky but it doesn't really effect us because an accident won't have an impact on the industry or our dealers I suspect.
However for offroad is a different story, and this is where my issue with Martin is (not so much Oxygen / Woosh etc etc, because they don't sell "proper" mountain bikes), if you use a dongle'd bike (either sold as such, or home done) at a trail centre or forest, part etc etc, and there is an accident your actions could and probably will result in ALL eBikes being banned from all trail centres and all forestry commission land and all mtb events. This will have a massive effect on lots of people business over the next x years, and also impact on the lives of many many individuals.
Like it or not eBikes are getting more and more press in the standard cycling magazines and most bike shops now have a much better idea of what they are. With this knowledge comes an awareness of the impact of the bikes, and the fact that people are using dongled bikes at venues is becoming more and more of an issue, and this is why I think pressure should be put on Martin to shop promoting it!
Now, all the above is different again for sPedelecs, because they are built and approved and tested to be what they are... so any shop selling them isn't modifying a CE approved product out of its legal category. So selling them is actually less legally risky for the trade, but the problems for the customer and the industry are still the same. On road, chances of getting caught and chance of it impacting on people other than the user are small. Offroad you'll essentially be riding a Moped at trail centres with all the negative impacts I've discussed above with dongle'd bikes.
So we don't sell the sPedelecs either, because the on-road ones we make can only be used illegally and we don't feel we should be putting our end customers in the position where they break the law. The offroad ones would end up being used in the forests and trail centres where I love to ride, and we don't want to risk these places being closed off to all eBikes.
I hope that all makes sense. Sorry for long post, I hope it clears up some of the misunderstandings regarding the liability issues.
