Thank you for all your help. I get the Unicorn aspect of my ask. I guess my head was at the Aventon Soltera II has most of what I want, and I'd happily pay an extra grand for more range and/or specs and/or lightness, but that doesn't seem to exist and/or is not possible.

Weight is where I will compromise the most say 50lb max (heck it's not like I'm not carrying way more extra weight on my body than an extra 10lb)

I definitely looked at reviews/specs of the Specialized Vada and it was kinda everything apart from the throttle, and I've generally been a trek/specialized owner in the road and hybrid bikes I've owed and like both brands, sp perhaps will test at my LBS.

On the throttle front, as someone who's done a lot of regular biking, I definitely see why it could be viewed dimly, but I rented one with a throttle a few weeks ago, and I loved it just on getting up to speed quick after a stop and the last 5 mins of a ride when I was tired.

Out of interest, what's the deal with not having throttles on ebikes; is it technological? Regulatory (I'm in US, Cali fwiw)? Tradition? Bike manufacturers fearing it will reduce their ability to state a good range?
