Mike,
Thanks for the big naked 40 pic. Now I have enough detail that I don't need to find one, just copy what I like instead. My buddy, who has a full metal working shop, has been begging me to buy the cargo ebike whose frame I'm about to retire. I need to come up with a design and say "Here, build me this, and you get my blue bike ready to go." My problem is making up my mind about what I want, which changes daily with new info on ES.
