I applaud any manufacturer who contributes to a forum like this. I've been involved in light aviation for many years and the vast majority of manufacturers/importers in that area don't dare show their head above the parapet in public forums.
It's easy to be critical of small suppliers in specialist areas, like electric bikes or small aircraft, but often criticism is borne from a lack of tolerance for the inevitable imperfections that will be present in such low volume products.
As someone who has spent a great deal of time developing an effective electric bike for my own use, and who has made some serious (and expensive) mistakes along the way, I can fully understand the problems.
Perhaps if we phrase any critical comment in a polite and constructive way we can encourage manufacturers and importers to contribute. I'm sure that the forum will be a richer place if we have their honest views.
