I'm wholly supportive of the BEBA concept but think it's best to stay primarily as a trade association to avoid conflicts of interests and possibly even internal disputes.
A national club for e-bikers may be an idea, but even that could cause problems. For example, an event like Presteigne would logically be run by the national club, but as it stands it's now to be a BEBA event.
.
I've said before that I think that Presteigne is more of a trade event open to the public much the same as events at the NEC or Olympia or Wembley etc.
If a club or association or fellowship or something similar was formed for consumers, then Presteigne would be on the members calender as one of the events to attend, a bit like the Ching challenge would also be and anything else relevant to ebiking.
I see two options for consumers - a formal route and an informal route, personal membership of BEBA would be down to individual choice.
The formation of a group for informal, but organised, events such as ride out's and gatherings can easily be arranged through a forum, or even a section devoted within a forum such as Pedelecs. This just needs enough people to put some effort into gathering together and not much more, over time it would build it's own momentum, but it would be a bit of fun and not take itself too seriously. There would be no membership fees or membership as such and all liability would be down to individuals, no risk assessments, no insurance (other than personal), no elf and safety required.
The formal formation of a club or such like brings a whole host of insurance, liability and health and safety issues that IMO would make the whole thing a PITA.
It would be good as a group of like minded people if members of the trade and BEBA joined in on gatherings and visa versa, we are all in this together.
